Title: Reaction device for brake booster
Inventor: KANDA MASANORI
IPC: B60T13/52
Filed: 1979-11-22
Abstract: PURPOSE: To prevent the deformation and damage of a power piston etc., by interposing a reaction disc as a reaction device for a brake booster, between the pressure receiving part of front surface of the power piston and the thrusting part of an output rod.  
     CONSTITUTION: In a brake booster which causes liquid pressure in a master cylinder through an output rod 18 provided in front of a power piston 3, a reaction disc 22 as a reaction device for the brake booster is interposed between the pressure receiving part of front surface of the piston 3 and the thrusting part of the rod 18. Since the periphery 22a of the disc 22 is surrounded by a nonlimiting space, the periphery 22a is only displaced outwards when the disc 22 is deformed or expanded. Therefore, the deformation or expansion of the disc 22 does not deteriorate the piston 3 and the disc 22 itself. The piston 3 and the disc 22 are thus protected from deformation or damage.

Filed: 1994-06-10
Abstract: PURPOSE:To provide a liquid crystal display device capable of displaying a color unable be displayed due to the restriction in the number of applied voltages by means of the color mixture of plural pixels. CONSTITUTION:A transformation table 19 outputs four bit voltage data complied with image data. The voltage data instruct either of voltages V0-V7 capable of being actually outputted by a D/A converter 23 and their intermediate value. When supplied voltage data indicate the voltages V0-V7, an intermediate color control circuit 21 supplys the upper three bits of the voltage data to the D/A converter 23 and when the voltage data indicate the intermediate value, the upper three bits of the voltage data and data adding '001' to the upper three bits are alternately outputted. The D/A converter 23 converts the supplied three bit data to either of the analog voltages V0-V7, supplys it to a column driver 33 and the color unable to be displayed by merely applying the voltages V0-V7 is displayed by means of the color mixture of plural pixels.

Title: Hinge structure of foldable apparatus
Inventor: URATA ATSUO
IPC: H05K5/03
Filed: 1993-06-23
Abstract: PURPOSE:To fix a cover so that the cover is not easily turned with respect to a case when it is in a closed or opened state, and to make it possible to easily open or close the cover. CONSTITUTION:When a cover is closed from an open state of a case, positional relationships between protrusions 5-1, 5-2 of a support 5 of a hinge and recesses 6-1, 6-2 of a boss 6 of the hinge, wherein relative rotational angles between the protrusions and the recesses is alpha deg., is as illustrated in figure (E). Since the boss 6 is pressed against the support 5 by a coil spring, forces are generated so as to cause the protrusins to slide into the recesses, and hence turning forces are generated in a direction of arrows (closing direction of the cover) as shwon in figure (E), so that the cover is pressed against the case, thereby preventing the cover from being easily opened, thus forming a locked state. When the cover is opened through an angle alpha deg. with respect to the case, the protrusions 5-1, 5-2 and the recesses 6-2, 6-3 are engaged with each other, thereby forming a locked state.

Title: Working system including robot
Inventor: YOSHIKAWA SHINJI
IPC: B23Q7/04
Filed: 1987-06-18
Abstract: PURPOSE:To improve working efficiency by forming the system in the title in such a way that a working cycle is not stopped when a lathe cannot continue working any more but both the lathe and a robot are moved to the origin before working. CONSTITUTION:When working cannot be performed any more, a working cycle is not stopped, but a signal is sent to a robot arm 5 for work carrying in and out and emergency return of the lathe 4. The signal is for directing that a completed work W2 which is machine-chucked 1 when the subsequent work becomes impressible is taken out by the robot arm 5 and put in a completed work tray 20, that a material work W1 held by the robot arm 5 is returned to a material tray where it was previously, and that the robot arm 5 and the lathe return to the origin. This origin means a mechanical origin as the condition before start of working. The robot arm 5 returns to the origin together with the lathe 4 when it receives the emergency return signal to wait for man. Non-work time can thus be reduced, and working efficiency can be improved.

Title: Pattern variable display device for pattern matching game machine
Inventor: KUREOKA TSUTOMU
IPC: A63F7/02
Filed: 1995-05-25
Abstract: PURPOSE: To perform smooth rotation fluctuation and accurate stop display of a pattern display body. CONSTITUTION: In a pattern unit, a rotating body 19 among the plural rotating bodies for which pattern belts are stretched and hung between outer peripheries is supported in a slide contact state by a boss 45 to a rotation supporting cylinder tool 48 directly connected to a motor 17. Then, it is elastically engaged in both forward and backward directions by an elastically deformable transmission braking member 55 disposed to the rotation supporting cylinder tool 48. Thus, since the rotating body 19 receives driving force at the time of acceleration by the activation of the driving motor 17 and is rotated in following up while receiving braking force at the time of deceleration, it is smoothly rotated while back and forth deflection in a rotation direction, that is advance rotation and return, etc., is actively restrained and the smooth rotation movement and accurate stop display of the pattern belts are made possible.

Title: Water-economizing tool for flushing tank
Inventor: HATA TOSHIKATSU
IPC: E03D1/33
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To economize water of a flushing tank as securing the flushing effect, by connecting a connection rod for a float and a vertically movable float fitted to an overflow pipe so as to freely and vertically slide, through a connecting body and fitting an acting body for closing a valve at the lower end of the float. SOLUTION: When stored water W1 is flushed to a toilet seat 1 by manipulation of a flushing lever 15, an acting piece of an acting body 32 for closing a valve presses the upper part of a spherical valve 12 in accordance with decrease of the stored water level to close the valve seat body 11 by the spherical valve 12 and stop flushing. At the same time, a connection rod 6 for a float is turned downward with the interlocking movement of the descending float 31 to open a cut-off valve through an actuation link 5 opening/closing the cut-off valve and supply water from the water supply part 4. As the acting piece of the acting body 32 descends prior to the descending float 31 and pushes the spherical valve body 12 and forcibly opens the valve seat body 11, discharing water volume can be regulated and the stored water W1 can be economized.  And as the full volume in the tank 2 is almost the same with the usual case, the flusing power can be secured and also the flushing effect can be kept.

Title: Semiconductor switch circuit
Inventor: HINO HIROBUMI
IPC: H03K17/60
Filed: 1984-07-25
Abstract: PURPOSE:To suppress an overvoltage generated when a semiconductor switch element turns off and to reduce the loss of a snubber circuit by using a coil having inductance L instead of discharging energy E accumulated in the capacitor C of the snubber circuit through a resistance, and utilizing oscillations of LC to regenerate E into a power source. CONSTITUTION:The capacitor 13 is inhibited by a diode 11 from being discharged, so VSC is held at (2Ed+DELTAEd). When TR3 turns on at a period t4, VCE is at 2Ed. When TR3 turns off at t5, a load current flows to 6 and VCE2 is only the forward voltage of 6 and when the load current is ceased, VCE2 varies to Ed. When IB2 is flowed at t7 to turn on a diode 2, a base current shown by ISTB flows to a pnp type transistor (TR)15 by the discharging of the capacitor 13. Then, TR15 turns on with this current ISTB and 13 is discharged through the closed circuit consisting of 13, 15, and 17 in order. This discharging current ISTC oscillates through the electrostatic capacity C of 13 and the inductance L of the coil 17, so it still flows even when VSC falls below Ed.
