Title: Molding method
Inventor: ODA SHIGEO
IPC: B22C15/02
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To execute a molding under good compactness and compression without developing a catch-in phenomenon by smoothly scraping the whole upper surface after pre-compressing molding sand near the inner surface of a molding flask and/or near the inner and the outer surfaces of a pattern and pressing with a pressing plate. SOLUTION: The molding sand S is charged into a space as a mold cavity demarcated with a pattern plate 2, molding flask 3 and banking flask 4. Successively, an annular thin plate body is lowered to pre-compress the molding sand S of a peripheral edge part at the lower end near the molding flask 3. Successively, after taking out the annular thin plate body from the molding sand S, the heap-up state molding sand S on the upper surface of the banking flask 4 is smoothly scraped with a scraping plate 6. By this method, the molding sand S is removed in the molding flask 3 and the banking flask 4 in the condition of non-leaning, i.e., in the condition of being difficult-to-develop the catch-in phenomenon.  Successively, the pressing plate is worked by working a cylinder and the molding sand S is compressed without developing the catch-in phenomenon to make the mold having wholly good compactness.

Title: Damping force adjusting device
Inventor: IKOMA AKIHISA
IPC: F16F9/46
Filed: 1990-03-13
Abstract: PURPOSE:To widen an adjusting range of generated damping force so as to be made available for hydraulic damplers most suitably by setting hydraulic pressure to be supplied to the respective back faces of leaf valves at extension and compression sides by means of a variable throttle which is changed by expansion force produced when voltage is applied to an electro-strictive member. CONSTITUTION:A piston rod 2 is inserted into a cylinder 1 in such a way that it freely comes in and out a piston section 3 is concurrently provided at its lower end section wherein the piston section slides within the cylinder 1 while partitioning the cylinder into a rod side oil chamber and a piston side oil chamber, and a piezo-electric element 4 acting as an electro-strictive member is disposed within a through hole 2a bored at the axial core center of the piston rod 2. A variable throttle 7 is controlled wide/narrow in such a way that a spool 73 is slid within a housing 70 with voltage applied to the piezo-electric element 4 acting as the electro-strictive member. When voltage applied to the piezo-electric element 4 is appropriately controlled, back pressure applied to the back face sides of respective leaf valves 5 and 6 is determined, so that the quantity of deflection at the outer ends of the respective leaf valves 5 and 6 is thereby changed.

Title: Thin film transistor and its manufacture
Inventor: NISHIMURA KENICHI
IPC: H01L29/786
Filed: 1993-03-22
Abstract: PURPOSE:To provide a TFT of positive stagger structure wherein the OFF- current between a source and a drain is restrained, and the manufacturing method wherein the TFT is formed without inreasing the number of masks. CONSTITUTION:Insulating films 106 are formed on side surfaces of both steps of a source wiring 102 and/or a drain electrode 104, and contact layers 105 are formed on the upper surfaces of both electrodes 103 and 104. As a result, the source electrode 103 and/or the drain electrode 104 do not come into contact with a semiconductor layer 107 which is formed so as to cover the electrodes. The insulating films 106 are formed by oxidizing both of the electrodes 103 and 104, in the state that masks formed on the contact layers 105 are left in order to form the source electrode 103 and the drain electrode 104, so that the insulating films 106 are not formed on the surfaces of the contact layers 105. Hence the contact layers 105 is in contact with the semiconductor layer 107. Superflous masks for forming the insulating films 106 are unnecessary.

Filed: 1992-03-18
Abstract: PURPOSE:To lower the hardness of an electrifying roller so as to decrease electrifying sounds and to execute uniform electrification by including many voids into the contact member and specifying the volumetric rate of hollow parts. CONSTITUTION:The electrifying roller 2 which is an electrifying member consists of a metallic arbor 2C made of a stainless steel, etc., for impressing an AC bias from an external power source 4 and the contact member 2a formed by dispersing conductive powders of carbon, tin oxide, etc., into EPDM, urethane, etc., and is formed by encapsulating the voids 2b1 of air, nitrogen, gaseous argon, etc., into the contact member 2a. The contact member 2a is so formed as to attain voids VH/VT>0.4 where the volume over the entire part of the contact member is designated as VT and the sum of the volume of all the voids 2b1 as VH. Since the electrifying roller 2 is constituted in such a manner, the roller is extremely light and soft and eventually the electrifying sound is small. The impressed frequency of a primary power source is increased and the interference of a laser beam with the unequal electrification occurring in the primary frequency is eliminated.

Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To allow tensile load to be exhibited well using a drillhole of a small radius by using a tension member combined with a C-turn-type tension member. SOLUTION: The part of a tension member 1 near its end is exposed by the required length, and a load resisting element 4 is suspended from the exposed part, and the tension member 1 is folded back starting from the load resistant element 4. The folded part serves as an anchored length part 2 of the desired length extending from the load resisting element 4 toward the ground. The tension member 1 is placed in a drillhole 9 and grout 10 is injected for anchoring. Such a tension member 1 curved at its end is combined with a tension member 12 made to turn in the form of C and hung on the load resisting element 4.  Thereby the tension member 1 curved at its end is combined with the tension member made to turn in the form of C, to form an odd number of anchors, with the anchored length part 2 of the tension member 1 enabling the tensile load of the tension member itself to be exhibited; also, the tension member needs to be bent by only a small amount, so that the diameter of the drillhole can be reduced.

Inventor: TAKAHASHI KUNIO
IPC: A47F3/04
Filed: 1990-03-15
Abstract: PURPOSE:To effectively illuminate without interrupting a visual line by providing a guide plate for guiding chilled gas to be diffused from a chilled gas diffuser to an article to be cold stored and so guiding it as not to be brought into contact with the inner surface of a transparent display cover to be introduced into a suction port, and proving the article from an illuminator in a housing through a placing plate made of a light transmission material. CONSTITUTION:Chilled gas to be diffused from a chilled gas diffuser 25 is guided into a guide plate 31 of a containing chamber N to cool an article S to be cold stored. Since the chilled gas after cooling the article S becomes negative pressure at a suction port 26 by the blowing action of a blower 10, it is sucked from the port 26 into a cooling chamber 24. Since no dew- condensation occurs in a cold storage display case at all, a labor of wiping the condensed dew is eliminated, and the display of the article S is held excellently. An illumination lamp 28 is energized to illuminate the article S through a placing plate 30. The upper position of the article S is disposed only with a transparent display cover 32 having no fog, there is no obstacle to interrupt a visual line to the article S in a state observed from above, thereby holding an excellent illuminating effect.

Filed: 1989-03-15
Abstract: PURPOSE:To industrially produce a grain-oriented silicon steel sheet having a very small iron loss by forming an oxide coating film by a sol-gel process on the surface of a grain-oriented silicon steel sheet after finish annealing. CONSTITUTION:A silicon steel sheet is finish-annealed to grow secondary recrystallized grains and an oxide coating film is directly formed by a sol-gel process on a forsterite coating film formed on the surface of the steel sheet.
