Title: Cutting machine
Inventor: OKAMOTO MAMORU
IPC: B23B39/00
Filed: 1983-05-04
Abstract: PURPOSE:To facilitate the elimination of chips produced during a cutting operation by allowing a cutting tool to act on a workpiece mounted on a mounting bench upward from its lower part, while allowing the workpiece to oppose to a main shaft above said shaft. CONSTITUTION:A workpiece 18 is fixed on an indexing rotatary table 19 via a mounting bench 20 in this drilling machine, while the table 19 is placed in a prescribed position, and a cutting tool 15 attached to the tip of the main shaft 13 is forced to act on the workpiece upward from the lower part to drill the workpiece, thus allowing chips produced during the cutting process to fall spontaneously. Accordingly, the elimination of the chips is promoted, while the chips are forced to flow down naturally due to the flow of cutting oil after lubrication and cooling by supplying the cutting oil from the toll 15 to a part to be cut via a rotary joint 16 on the lower end part of an inclined head 6 during the cutting.

Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To shorten the low speed traveling time of a cage side door on the closed end and prevent increase of a door hitting noise by the entrance side door on the closed end by a simplified construction. SOLUTION: An elevator door device is composed so that first a cage side door 6 starts traveling preceding a main link 11a, an auxiliary link 8a and a fulcrum 7a when a door is making an opening movement and a checking cage side engagement piece 39 does not make a relative movement with respect to the door 6a but only the driving cage side engagement piece 38 makes a relative movement with respect to the door 6a in the door opening direction by being pressed by a cam surface 47 of the auxiliary link 8a through a bearing 46 and a link 56, while an entrance side movable engagement piece 30 and a fixed engagement piece 31 are sandwiched between the two engagement pieces 38, 39.  It is also composed so that the initial speed of the entrance side door when it starts to travel may be the same speed of the cage side door 6a with the cam surface 47 in the stopped condition of its relative movement when door opening action is taken.

Title: Piston for internal combustion engine
Inventor: SHIMIZU SHIGERU
IPC: F02F3/00
Filed: 1978-06-29
Abstract: PURPOSE:To decrease the maximum value of impact noise by positioning the center of a piston pin eccentrically on the anti-thrust side for the shaft center of a piston and allowing the impact noises in exhaust and intake stroke to be nearly equal. CONSTITUTION:On a piston 1, a piston pin 4 is arranged eccentrically by a on the anti-thrust side from the shaft center Ax, and the thick parts 1a and 1b thicker than the thrust side are formed on the anti-thrust side of the piston 1, and thus, the center of gravity G of the piston 1 is positioned close to right above the center 0 of the piston pin 4. Owing to such constitution, the impact noise in explosion stroke of the piston depends on a thrust force R and an inertia force Fi, and as the moment around the center 0 of the piston pin due to the inertia force Fi is nearly zero, the moment M can be reduced, and impact noise can be suppressed.

Title: Received signal processing circuit in radar and similar apparatus
Inventor: SUZUKI TOMOHIKO
IPC: G01S7/527
Filed: 1980-06-11
Abstract: PURPOSE:To prevent the steep rise of the received signal, by supplying a specified DC voltage signal in the receiving signal, at the time separated from the transmitting poit of time in a very short time length. CONSTITUTION:Transmission is made based on a transmitting trigger A1 and a received signal B1 is obtained. A level V1 at the point of time separated from the generation of said signal B1 by the time length T1 is sampled and held by a sampling pulse c. Said holding continues until the generation of the pulse c in the next period. Said level V1 is sent to an adder 7 via a gate circuit 5 during the period of the time length T2 before the generation of the next trigger A2. At the time the sending is terminated, the trigger A2 is generated, and the received signal B2 is obtained by said trigger A2 and sent to the adder 7 via a gate 6. Then a signal g from the adder 7 is sent to a differential circuit 8 where a signal h is obtained. Thus the steep rise of the received signal can be prevented.

A diffusion layer reaching the base layer is then formed in the vicinity of the collector on the layer followed by formation of a base contact. The layer 2a is then removed up to a masking part for forming an electrode thus exposing the collector contact 20.

Title: Lubricating oil pump of two-cycle engine
Inventor: NOMURA KENICHI
IPC: F01M1/02
Filed: 1988-03-31
Abstract: PURPOSE:To prevent the suction of the air in an oil storage chamber into a metering pump chamber by setting the opening position to a distributor accommodating cylinder hole of a metering suction passage, below the opening position to the oil storage chamber. CONSTITUTION:When a worm gear 4 is revolved through the engine revolution, a distributor 5 revolves, and plungers 8 and 10 moves vertically in reciprocation through a cam surface 11, and the charge plunger 8 having a large diameter sucks a large quantity of oil from an oil tank A, and said oil is discharged and stored into an oil storage chamber 13. While, the metering plunger 10 sucks the oil in the oil storage chamber 13 through a metering suction passage 19 and a suction passage 21 and supplies said oil into an engine C from a discharge passage 22. Further, the excessive oil in the oil storage chamber 13 is returned into the oil tank A through a passage 17. The metering suction passage 19 communicates to the bottom part of the oil storage chamber 13 and the lower part of a metering cylinder hole 6 under the oil storage chamber 13. Therefore, the inflow of the gas bubbles in the oil storage chamber into the metering pump chamber is prevented.

Title: Pressure-sensitive transfer erratum correction material
Inventor: YAMABE KIYOSHI
IPC: B41M5/132
Filed: 1990-03-28
Abstract: PURPOSE:To improve the drying properties of rewritten characters by a method wherein a white ink composition prepared by dissolving or dispersing a white pigment, a filler, and a binder, as main components in a volatile solvent is applied on a substrate and dried to form a white ink layer, and a specific surfactant is compounded in the white ink layer composition. CONSTITUTION:One or more kinds of surfactants having a 10 or more Hydrophile-Lipophile Balance value are compounded in a white pigment, such as titanium dioxide, suitable for correcting or hiding an erratum, a filler, and a binder, such as resin and rubber. This compound is dissolved or dispersed in a volatile solvent to produce a white ink composition. This is applied on a flexible substrate and dried to form a white ink layer. At this time, in the process of volatilizing the volatile solvent, a groove-form rough surface is formed on the ink layer. Writing on the surface by a water pen, a fountain pen, or the like, results in the water content contained in the written ink being penetrated into the white ink layer through the groove-form rough surface by a capillary action. Furthermore, because the water content is adsorbed into the hydrophilic groups of the surfactant, the rewritten lines or characters are rapidly dried.

Title: Taking out device for wave motion power
Inventor: KITABAYASHI SEIICHI
IPC: F03B13/18
Filed: 1979-06-25
Abstract: PURPOSE: To take out the ocean energy as the turning force by a method wherein the unbalance of gravity of floating power is made to be caused on both sides centering around a barrel shaft at the time of rotary barrel sinking into the water and of its separating from the water surface.  
     CONSTITUTION: Respective openings 51W54 are all provided adjacent to the partitions on the same turning direction sides. Consequently, as to the water receiving chamber 11, the water enters into from the opening 51 but when the water taken in reaches to a certain extent the air has its escape cut off thus to stop the water invasion. Likewise as to the water receiving chamber 14, the air remains staying. On the other hand, as to the water receiving chambers 12, 13 the openings 52, 53 are positioned high in their respective chambers so that the air escapes according to the invasion of water to fill the chambers 12, 13 with water. Accordingly the floating power of the air in the water receiving chambers 11, 14 together with the tare of the water in the chambers 12, 13 act the torque turning to the right on the barrel shaft 2 to take out the ocean energy.
