Title: Compressor
Inventor: NISHIMOTO KAZUMI
IPC: F04B35/01
Filed: 1993-06-28
Abstract: PURPOSE:To provide the possibility of starting with a low voltage without requiring any particular start device, large-sized motor, or costly pressure control device by furnishing a solenoid to move a suction valve with a plunger which is in contact with the suction valve. CONSTITUTION:A plunge 19 in contact with the suction valve 14 is moved by a solenoid 20 installed on the outside of a cylinder head 16. When a compressor 1 is to be started, the plunger 19 in contact with the suction valve 14 is attracted by feeding current to the solenoid 20, and the load for fluid compression at this time is reduced by moving thereby the suction valve 14 and opening it forcedly, and also at the time with overload. the load of fluid compression due to high pressure is reduced. Thus it is possible to start a drive motor 2 with a low voltage, while at the time of overload, failure due to lock of the motor 2 is avoided.

Title: Control method for cargo handling machine
Inventor: DOBASHI AKIRA
IPC: B25J9/10
Filed: 1994-07-08
Abstract: PURPOSE:To attain the decelerated state with no impact by setting the optimum acceleration and the optimum over-acceleration for the control via the speed command, combining deviation value between the present speed and command speed, and setting the method for selecting one of three regions of over- acceleration, constant speed, and underacceleration for speed control. CONSTITUTION:The command force applied to a force sensor 4 via the arm 1 of an operator is converted into the command signal by a command converter 5 for acceleration/deceleration control. The command converter 5 is provided with a speed comparator 51 outputting the difference signal DELTAV between the command value from the force sensor 4 and the present operation speed detected by a speed sensor 8.1 The first discriminator 52 compares DELTAV with the absolute value of the speed deviation alpha and judges whether over-acceleration (or under- acceleration) should be applied or not. The second discriminator 53 discriminates whether the acceleration is over-acceleration or under-acceleration based on the relation between the value of DELTAV and the present acceleration ai and applies the speed control of over-acceleration, constant speed, or under-acceleration to a servo motor 7 based on the discriminated result.

Title: Evaporator for use in non-azetropic mixture medium
Inventor: KOYAMA YOSHIO
IPC: F28D7/16
Filed: 1985-07-18
Abstract: PURPOSE:To eliminate the composition distribution of a medium within the evaporator to provide an evaporator for use in a non-azetropic mixture medium, having an excellent heat- exchange function by disposing smoothing plates for securing the recirculation flowpath of the medium along the longitudinal direction of a heat transfer tube bundle. CONSTITUTION:The smoothing plates 3 are disposed along the longitudinal direction of a heat transfer tube bundle 2 within an evaporating chamber 1 so that the two smoothing plates 3 encircle the side surface of a heat transfer tube bundle 2 along the longitudinal direction of the heat transfer tube bundle 2 so as to secure the recirculation flowpath 6 for a medium liquid 5 between the outer shell of the evaporating chamber 1 and the smoothing plates 3. By the provision of the smoothing plates 3, natural circulation vortexes 19 in the vicinities of the upper parts on the right and left hands of the tube bundle 2, which are produced in a conventional evaporator 12, are eliminated to remove the ununiformity in the medium composition. As a result, since the total surface area of the heat transfer tube bundle 2 is effectively used for the heat transfer, downsizing of the evaporator can be realized. Further, when the present evaporator 20 is incorporated in the thermal apparatus such as a heat pump device, the function anticipation of the device can be easily conducted because no maldistribution of media having different compositions exists in the evaporator 20.

Filed: 1980-11-10
Abstract: PURPOSE:To efficiently operate a brushless motor by applying a pulse having a duty ratio proportional to the speed deviation signal to the input of one complementary transistor to which a current from a stator coil is flowed, thereby preventing the through phenomenon. CONSTITUTION:When the outputs of magnetic detectors 1, 2 are respectively L and H, transistors TR14, 25 of complementary amplifiers 4, 5 of output terminal are ON, while transistors TR15, 24 are OFF. Thus, a current from a power source VCC flows in a circuit of the TR14, the stator coil 7-1, the TR25 and a ground terminal G. In the amplifier 4, the TR15 is OFF with constant resistance. Even if a rectangular pulse is applied to the base of a modulation transistor TR 16, no through phenomenon occurs. In the amplifier 5, the TR24 is OFF, and the power voltage VCC is constant. Accordingly, no through phenomenon occurs. The TR25 is modulated with the rectangular pulse from a speed control circuit 10 via the modulating TR26, and the duty ratio of the rectangular pulse is controlled by the current of the stator coil 7-1.

Title: Power supply reset circuit of contactless switch
Inventor: KAMIYA FUMIO
IPC: H03K17/22
Filed: 1984-07-27
Abstract: PURPOSE:To attain reset operation of a power supply even when the power supply is intermitted frequently by discharging immediately an integration capacitor of the power supply reset circuit every time a power supply is interrupted. CONSTITUTION:When a power supply is applied and a power supply voltage reaches a prescribed value, a voltage detection circuit 10 drives a constant current source 11, a prescribed current flows from the constant current source 11 to be flowed to a transistor (Tr)12, a Tr14 of a current mirror circuit CM1 and an integration capacitor C1. Since the emitter area of the Tr13, 14 of the circuit CM1 is 1S:nS, the collector current of the Tr12 is amplified to n-times by the circuit CM1. When a terminal voltage across the C1 is increased and the collector and the collector voltage of the Tr14 rises and reaches to a prescribed level, a comparator 16 gives an output to attain the operation of a contactless switch. When the power is turned off, the power supply voltage is lowered, the base potential of the Tr15 is decreased and the electric charge in the C1 is discharged rapidly through the Tr15. Thus, reset is attained surely even when the power is applied again.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To control the lowering speed of a shutter door with viscosity resistance by alternately stacking plural fixed plates and rotary plates in an operating chamber filled with silicone oil at the end of a winding shaft. SOLUTION: A ring-shaped operating chamber 40 is formed by hubs 21, 22, 23 sequentially engaged with a winding shaft 5 to be rotated together and a housing 30 where plural thin ring-shaped fixed plates 50 are disposed at the end part of the winding shaft 5, and filled with high-viscosity silicone oil. Plural rotary plates 61, 62, 63 respectively engaged with the hubs 21, 22, 23 to be rotated are stacked alternately between the fixed plates 50. When the winding shaft 5 is rotated during the closing of a shutter door, the hub 21 and the rotary plate 61 are rotated, sequentially the hub 22 and the rotary plate 62, and the hub 23 and the rotary plate 63 are rotated to generate viscosity resistance in a space up to the fixed plates 50.  Accordingly, brake torque is increased in proportion to the rotating speed of the winding shaft 5, so that the increase in the lowering speed can be restrained by the increase in the suspended weight of the shutter door.
