Title: Buffer member for semiconductor device
Inventor: IWASAKI YOSHITAKA
IPC: B65D85/38
Filed: 1993-01-18
Abstract: PURPOSE:To prevent decrease in quality of semiconductor devices due to an external shock during transfer of the semiconductor devices. CONSTITUTION:In a buffer member 101 for semiconductor devices installed between a tray group 107 in which a plurality of trays are stacked on which a plurality of semiconductor devices are respectively mounted and a container 109 for holding the tray group 107, unevenness parts are formed on the inner and outer surfaces of the buffer member 101, and protrusion parts 105-1 of the inner surface come into contact with the tray group 107 to fix the tray group 107, and protrusion parts 103 of the outer surface come into contact with the container 109 for holding the tray group 107 to fix the entire buffer member 101. Thus, even if an external shock is applied to the container 109 for holding the tray group 107, the protrusion parts 103 in contact with the container 109 correspond to recess parts 103-1 and as a result, a large force can be prevented from being directly applied to the semiconductor devices.

Title: Safety device for electronic control circuit
Inventor: HYODO HITOSHI
IPC: F02D45/00
Filed: 1986-01-14
Abstract: PURPOSE:To set the output state of an electronic control circuit to a designated output state in case of runaway of the circuit by providing a discriminating circuit or the like which discriminates the output of a pumping circuit which outputs the operating state of the electronic control circuit. CONSTITUTION:When the duty ratio of a pumping output is 10%, outputs of a frequency/voltage converting circuit F/V and a duty ratio/voltage converting circuit D/V are within a prescribed voltage range, and outputs of comparators COMP1 and COMP2 are in the high level, and gates are opened, and an electronic control circuit is in the normal operating state. If the processing speed in the circuit CPU is changed, the output of the circuit F/V is on the outside of the prescribed voltage range, and outputs of comparators COMP1 and COMP2 go to the low level. Consequently, NAND gates 1, 2, and 3 are closed. Thus, a solenoid of a control valve V1 or the like is not excited independently of the high or low level of the output port of the CPU, and the certain speed running control is prevented from falling into an abnormal state because of runaway of the CPU.

Filed: 1983-01-18
Abstract: PURPOSE:To enable to manufacture by solving a problem of mechanical strength by improving a hot water tank in a state pressureless and open to the atmosphere and a metallic material is converted into plastic material, by so constituting that a valve to be controlled by a temperature setting device and a valve to be controlled by a liquid level detector are provided and cold or hot water in the hot water tank is circulated between the hot water tank and a heat collector by a pump. CONSTITUTION:When pressurized supply water such as service water is supplied up to the upper limit of a hot water tank 2 from a source 4 of water supply, supply water is suspended by turning a solenoid valve 5 into a closed state through detection of the upper limit of a water level by an electromagnetic bar 7 of a water level detector 6. Althrough water supply to a heat collector 1 is not carried out at that time, it is better to supply water by operating a solenoid valve 7 in an open state by making the solenoid valve 7 short-circuit (manual operation) electrically. As the solenoid valve 7 is opened when a temperature of the heat collector 1 becomes more than a set value of a temperature setting device 10 under the above state, a pump 3 is operated by detecting deterioration of pressure of a pipe system by a pressure switch built in the pump 3. Cold water in the hot water tank 2 is fed to the heat collector 1 through operation of the pump 3, and hot water is returned to the hot water tank 2 from the upper part through a check valve 14. The operation of the pump 3 is turned into an intermittent operation as the operation of the pump 3 is controlled by the temperature setting device 10.

Abstract: PURPOSE:To prevent flaw or loss of the surface of a pad without loss of conductivity with the pad by providing a contact having conductivity and elasticity at the end of a probe. CONSTITUTION:A mount 4 formed in a semicircular disc state is provided at the end of a probe, and a contact 5 having elasticity and excellent conductivity is mounted at the lower part. The contact 5 is formed with a magnetic conductive material 7 linearly in an elastic element 6 formed of rubber material in a semispherical state. The end of the contact 5 is positioned on a pad 2, and a probe 1 is moved down while holding the state. Then, the lower surface of the contact 5 is brought into contact with the pad 2. In this case, the contact 5 is effected by pressure by an energizing force applied to the probe, so deformed as to be collapsed to absorb overload at the time of impact, thereby eliminating flaw or the like on the pad 2. A magnetic conductive material 7 is deformed, but since it is formed in close contact therewith, its conductive characteristic is not lost.

Abstract: PURPOSE:To surely discriminate the intrusion of a human body by having total >=3 detecting sensors disposed along the two direction; the moving direction and height direction of the human body and previously set recognition patterns for detecting the human body. CONSTITUTION:A program 6 judges that detection signals are not the detection of the human body by the recognition patterns for human body detection stored in a memory 4 if the signals are not simultaneously outputted within a specified period of time when the detection signals of a prescribed level are inputted form the detecting sensor 2c to a computer device 3. The program distinguishes the intrusion of the human body or not by discriminating whether there are the outputs from the detecting sensor 2c or not within the specified time when the detection signals are simultaneously outputted from the detecting sensors 2a, 2b. Namely, the recognition patterns for human body detection are previously set by the output order of the respective sensors relating to the moving direction and the height direction and the human body is exactly detected by comparing these patterns and the actual patterns of the sensor outputs.

Title: Vane pump
Inventor: TANIGUCHI NAONORI
IPC: F04C2/356
Filed: 1980-01-25
Abstract: PURPOSE: To reduce the capacity of a motor by a method wherein there is provided a passage of small diameter for supplying back pressure oil on a vane holder part which holds vane in such a manner that it can slide freely and it makes possible to supply pressure oil only when the occasion should arise.  
     CONSTITUTION: When a rotor 3 is rotated by a motor 13, the oil from an inlet port Q is compressed and moves to a high pressure side, while since the pressure oil on the high pressure side reaches the back part of a vane 7 through a small- diametrical passage (u) for the back pressure oil and gives a back pressure to the  vane 7, the oil pressure on the high pressure side rises. When the pump is stopped in order to reduce the pressure of discharge oil and a back pressure relief valve 20 is turned off, pilot pressure oil is discharged, the vane 7 becomes free from back pressure and the vane pump 15 cannot generate pressure. In this manner, since the discharge pressure can be generated only when it is required, a motor 13 of a small capacity can be applied for the vane pump 15 having a structure where energy is accumulated in a fly-wheel.
