Title: Tanden-type master cylinder
Inventor: KOBAYASHI HIDEYUKI
IPC: B60T11/20
Filed: 1979-10-08
Abstract: PURPOSE: To permit the boosting characteristics of a master cylinder to be independent of the brake pedal stepping speed by allowing the compensation ports in the pressure chambers of a tandem-type master cylinder used in the hydraulic brake gear of a vehicle to be connected and disconnected with the fluid chamber around the secondary piston.  
     CONSTITUTION: With a brake pedal operated; a primary piston 2 and secondary piston 3 slide leftwards together, and a cup 11 disconnects a compensation port 1f from a fluid chamber 10 communicated with a reservoir 16 as well as a cup 12 closes a compensation port 1e. Further advance of the piston 2 causes the pressures in pressure chambers 7, 8 and 9 to rise. Because the pressure-rise rate of the first chamber 7 is larger than that of the second chamber 8, the fluid in the first chamber 7 flows into the second chamber 8 through a hole 2c and a cup 6, and is sent to a wheel cylinder together with the fluid in the second chamber 8. When the fluid pressure exceeds a given value, a relief valve 18 operates to stop the pressure rise. After that, the external force applied to the piston 2 is consumed to raise the pressure in the second chamber 8. Therefore high pressures are generated in the second and third chambers 8 and 9, and sent to the wheel cylinder.

Filed: 1979-10-08
Abstract: PURPOSE: To reduce the number of part items and make a device small by using a spring commonly for energizing two relief valves in the relief valve system of a hydraulic-type toggle joint used mainly for vehicles.  
     CONSTITUTION: In the upper part of the main body 25 of a cylinder is provided a cavity 71 communicating to an inlet 26 in the right end thereof, to a ring-shaped groove 62 in the left end thereof and to a drain chamber 37 in the central part thereof, and a relief valve 72 is incorporated in the right-end part of the cavity 71, whereby the rise of the pressure in a pressure chamber 36 above a fixed value is prevented. Moreover, in the left-end part of the cavity 71 is incorporated a relief valve 73, which prevents the pressure in the pressure-oil storing chamber 65 of an accumulator 64 from rising up to an extraordinarily high level. A spring 76 for seating the ball-like valve body 75 of the relief valve 72 is also used for seating the valve body 78 of the valve 73 on a valve seat 77.

Filed: 1980-09-18
Abstract: PURPOSE: To increase the melting amt. of a wire and to improve welding speed by melting the wire by the positive polarity pulse current of which the peak value is below the transition current value and transferring globules at the reversed polarity pulse current above the transition current value.  
     CONSTITUTION: Welding pulse current is so set as to have the positive polarity pulse current part of which the peak value IP 1  at which a wire 1 melts is below the transition current value and the reversed polarity pulse current part of which the peak value IP 2  in succession to this is above the critical current value. Then, the quantity of heat input to the wire 1 increases in the part of the positive polarity in the first half of the pulse current and the wire 1 melts quickly. In the part of the reversed polarity in the second half, the molten part at the leading end of the wire 1 is finely grained, and transfers to base metals 3. Namely, the wire 1 is simply heated in the first half and the transfer to the base metals 3 occurs always in the reversed polarity part in the second half. Thereby, the spatters by short circuiting are reduced and the occurrence of undercut is prevented.

Title: Rotary disk for speed detection
Inventor: ASANO HOKAO
IPC: G01D5/36
Filed: 1984-06-25
Abstract: PURPOSE:To obtain mechanical strength, attain high division, and to improve stability in size by arranging a plane part and a V groove part alternately in the outer peripheral part of the rotary disk made of transparent resin. CONSTITUTION:A plane part 2 and a V groove part 3 are formed alternately at the outer peripheral part of the rotary disk 1 made of transparent resin. Incident light from a light emission part travels straight in a plane part, but is refracted at a V groove part 3 and does not reach a photodetection part. This disk 1 having transmission and nontransmission parts is rotated between a light emitting and a photodetecting element to detect the rotating speed. Thus, a plane part 2 and a V groove part 3 are provided to the outer peripheral part of the disk 1 to constitute a transmission and a nontransmission part, so the problem of a burr treatment and a run of resin during resin formation is eliminated to increase the mechanical strength, attain high division, and improve the stability in size.

Abstract: PURPOSE: To hold the cutting angles of tool cutting edges substantially constant even on tool positional adjustment, by forming two slides as connecting links between two double-armed cranks of a parallelity of crank mechanism. CONSTITUTION: Positional adjustment to a tool requires axial movement of an operating rod 34, which is converted into the corresponding rotary motion of double-armed cranks 20 and 22 that moves two slides 12 and 14 simultaneously and oppositely to each other. In this movement, the centers of gravity S of the slides 12 and 14 middled between their respective two crankpins 24 and 26, and 28 and 30 are also moved simultaneously and oppositely to each other to maintain the mass balance between these slides 12 and 14. The slides 12 and 14 are connected together by the double-armed cranks 20 and 22, such that the centrifugal force caused in these slides 12 and 14 never counters the movement of these cranks 20 and 22.
