Title: Manufacture of inner circumferential blade grinding wheel
Inventor: TAKAHASHI TSUTOMU
IPC: B24D3/00
Filed: 1995-05-16
Abstract: PURPOSE: To decrease change of a calf width even in the initial period of cutting and to perform cutting in high flatness, by electrochemically removing a metal plating phase of forming a flat part over a fixed thickness, and protruding a super abrasive grain, buried in the flat part, by a fixed protruding amount. CONSTITUTION: In a trueing process, a flat part in parallel to both side surfaces of a base metal is formed in both side surface of an abrasive grain layer 6. Thereafter, in the next electrolytic dressing process, a metal plating phase 5 of these flat parts is electrochemically removed over a fixed thickness, to form a protruding amount averaged part 24 almost parallel to the both side surfaces of the base metal further with a uniform abrasive grain layer protruding amount.  When the protruding amount averaged part 24 is thus formed, changing thickness of the abrasive grain layer 6 is decreased even in the initial period after cutting is started, further by stabilizing an abrasive grain protruding amount and abrasive grain holding force in the both side surfaces of the abrasive grain layer 6, in addition to decreasing changing a calf width, sharpness is excellent, to stabilize a cutting direction, so as to enable flatness to enhance of a cut surface.

Title: Envelope with wavy flap
Inventor: KAI HISAO
IPC: B65D27/16
Filed: 1989-05-12
Abstract: PURPOSE:To improve the workability and obtain a sufficient adhesion by using a single sheet of strippable paper in common for at least two envelopes and cutting the edge of envelope flap into a wavy form. CONSTITUTION:Envelopes are overlapped, one above another, with about 1/4 the average width of the flap 2 exposed and such exposed parts of the flaps are coated with an adhesive 3. The adhesive 3 is immediately covered with strippable paper 4 wider than the exposed area of envelopes 1, i.e., a number of the envelopes 1 are attached to a sheet of strippable paper 4 and, when the envelope is used, they are removed one after another starting with the endmost envelope 1a. Since the width (a) of the exposed part of the adhesive coated area 5 is narrow, even if a number of envelopes are attached to a single sheet of the strippable paper, the entire length of the overlapping envelopes can be confined within a moderate range.

Title: Hydraulic pressure shock absorber for vehicle
Inventor: MORITA ISAMU
IPC: F16F9/50
Filed: 1979-09-13
Abstract: PURPOSE:To produce an effective attenuation force which is controlled by an orifice by increasing a preset force of a slide valve and by increasing differential presures between the upper and lower chambers of a piston. CONSTITUTION:A control rod 19 is actuated to move vertically by a control unit. A spring bearing 29, which is contact to the bottom of the piston rod 11, controls the upperward movement of the control rod 19. The downward movement of a piston 10 in an inner cylinder 2 increases the pressure of a lower chamber B. In- creased differential pressure between the upper and lower chambers A and B are obtained due to a high preset force of a slide valve 13 and thus reduces the pressure of the upper chamber A to a greater extent. The oil in the lower chamber B of the piston flows to an clearance F between a taperd portion 25 and a projected portion 28 through passages D and E and then reaches a passage G and flows into the upper chamber A through passages 23 and 24. In this process, the clearance F between the tapered portion 25 of a slider 21 and the projected portion 28 functions as an orifice to control flow rates and thereby obtains attenuation force in the compression stroke.

Title: Ground load controller
Inventor: IZAWA MASAKI
IPC: B60G17/015
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To further increase the generation limit of grip force of each tire and improve escape performance at the time of a stack, in particular, by temporarily increasing ground load of a drive wheel by an actuator provided between a car body and an axle when the drive wheel is judged to be stacked. SOLUTION: A tire 1 is provided with a linear actuator 5 due to a hydraulic driving between a lower suspension arm 3 and a car body 14. A command value is adjusted from stack signals generated in a stack state detecting part 27, signals from a spring upper acceleration sensor 22 and a spring lower acceleration sensor 23 and signals from a load sensor 20. By driving a servo valve 10 so as to equalize target load and actual load, stroke is generated in the actuator 5. Upper and lower acceleration of a direction increasing tire ground load in the drive wheel is generated in either one of sprung mass and unsprung mass. Therefore, the limit of escape performance at the time of generating a stack is stably increased.

Filed: 1977-09-30
Abstract: PURPOSE:To prevent the abnormal deformation of a material to be rolled formed in case of blooming rolling, by constraining the left and right flanks of the material to be rolled by the side taper portions or roll kalibers up to a final pass from an initial pass. CONSTITUTION:Kalibers I, II for an initial pass and the next pass with wide kaliber width are mounted to both sides of rolls of roll kalibers and kalibers III, IV, V with narrow kaliber width are disposed to a center portion. Kaliber I steel ingot a for initial pass is rolled and changed into a steel piece b, further turned and rolled to a steel piece c, and rolled to a steel piece d by a kaliber 2. The steel piece d is rolled to steel pieces e-f by the kalibers III, IV, V at the center portion, and rolling reduced to a fixed section dimension. In this case, since the left and right flanks of a material to be rolled are constrained by the side taper portions of the roll kalibers up to the final pass, the steel pieces are equalized, thus stably obtaining a rolling material that there is no defect on its surface and its quality is excellent.

Title: Rolling mill
Inventor: NARISHIMA SHIGEKI
IPC: B21B1/22
Filed: 1986-05-22
Abstract: PURPOSE:To prevent the generation of sheet breakage and to roll a material to a flat sectional shape by disposing upper and lower tension rolls in proximity to work rolls to at least either of the inlet side or outlet side of a multi-stage rolling mill and varying the rotating speed and deflection thereof. CONSTITUTION:While the upper and lower tension rolls 5, 6 are kept applied with a decrease deflection by divided press rolls 8-10, said rolls are driven at the speed lower than the speed of the upper and lower work rolls 1, 2 by a motor 14. Since the rolling material 12 is held lightly rolled down by screw- down cylinders 7 by the tension rolls 5, 6, both ends in the transverse direction is elongated larger than in the central part. The transverse distribution of the tension is, therefore, larger in the central part T2 and smaller at the ends T2', T2''. The central part where the tension is large is mainly rolled and elongated. The sectional shape in the transverse direction of the rolling material 12 rolled by the work rolls 1, 2 is made into the flat shape if there is a tendency to edge waving. Since the tension distribution of the rolling material is smaller at the transverse ends than in the central part, the generation of a crack from the transverse ends is obviated.

Abstract: PURPOSE:To readily form epitaxial layers of different partial thicknesses with flat surfaces by forming a polygonal recess of a main body at the side parallel to the (100) direction on the (100) surface of a P type Si and covering the surface with an N type epitaxial layer. CONSTITUTION:A window having a side parallel to (100) is formed at an SiO2 52 on the (100) surface of a P type Si substrate 51, and is anisotropically etched, thereby forming a recess 501. After N+ type layers 53, 531 are diffused, an N type epitaxial layer 54 is superposed, and an SiO2 mask 55-551 are covered on the recess 502. It is again anisotropically etched to flatten the surface of the layer 54, and the remaining SiO2 mask 55 is removed. Thereafter, a high withstand voltage part 101 and a low withstand voltage part 102 are isolated via the P type layer 59, and a linear IC is formed in the ordinary way. According to this structure, an Si device having an epitaxial layer having partly different thickness and flat surface can be readily obtained by employing the mask of the side parallel to the prescribed direction as a main body and performing twice anisotropic etchings and once entire epitaxial growth.

Title: Controlling method of food thawing using infrared ray detector
Inventor: KUSUKI SHIGERU
IPC: A23L3/365
Filed: 1978-09-26
Abstract: PURPOSE: The time when food thawing will finish is automatically determined depending upon change in signals of temperature detecting by infrared rays after the temperature has reached a predetermined level, thus effecting uniform heating independently from the conditions of the food.  
     CONSTITUTION: After the detecting signals attains the predetermined level, it stops for a certain time T and cycles of heating to a predetermined level are repeated to lessen the temperature difference between the inner side and the surface, thus the difference ΔS between the signal that reduces within time T and the predetermined level becomes smaller with every cycle. When this ΔS becomes smaller than the threshold value ΔS that has been predetermined, the heating finishes. This way of controll can finish thawing in a shorter time when thin food is thawed, and in a longer time with thick food, resulting in uniform thawing.

Title: Controller for airflow of boiler
Inventor: TAKADA SHINJI
IPC: F23N3/00
Filed: 1983-06-28
Abstract: PURPOSE:To perform safe and continuous operation of a boiler even if a power source fails in operation, by a method wherein, when a V power source (a power source for a first fan) is failed in operation, a power source is switched to a commercially-available power source, an airflow change command is given to the other fan to control a change in a wind pressure in a boiler into a wind pressure prevailing within a safety range. CONSTITUTION:In case power source V for a first fan 1 is failed in operation, a control signal is positively sent to also a second fan 2 to safely operate a boiler 3. When the power source V for the first fan 1 is failed in operation, a given function signal is sent to the terminal of a control input part 18, and a damper 16b is operated to decrease a wind pressure in a boiler. When an airflow change signal equivalent to an airflow Q2 at the control input terminal 18 is sent to the second fan 2, a wind pressure in the boiler 3 is reduced to a value equal to an airflow difference Q1-Q2, and is reduced over the hazardous wind pressure of a boiler. A command on an airflow Q2 (a control signal sent to the terminal 18) gives an opening signal to, for example, a damper 16b of the second fan 2 for a specified time, and thereafter, by sending a closing signal, a wind pressure is restored to a value prevailing before the power source V is failed in operation to achieve a purpose.
