Title: Monitor device for processor stall
Inventor: YOKOBAYASHI TAKESHI
IPC: G06F11/30
Filed: 1988-01-14
Abstract: PURPOSE:To inform the occurrence of the stall of a processor to be monitored even to other processors by providing a memory means to store the receiver processor of the interruption information which is designated by an information receiver setting instruction. CONSTITUTION:When a processor stall monitor device 2-1 monitors the occurrence of the stall of a processor 1-1, the device 2-1 stores the information showing the receiver processor of the interruption information into a register 13 after deciding that the received data shows an information receiver setting instruction. Thus the device 2-1 can inform the occurrence of the stall of the processor 1-1 to the interruption receiver processor stored in the register 13 by an interruption via a transmission/reception part 11 in case no monitor restart instruction is received from the processor 1-1 for a prescribed time. Then the processor received the relevant information can take over the process so far carried out by the processor 1-1 having the stall. As a result, the system monitor is possible in response to the application form of a multi-processor system.

Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To provide a fixing device capable of obtaining an excellent image without causing faulty fixing at the abutting position of the temperature excessive rise preventing element of a heater or having no shininess. SOLUTION: This device possesses the heater 102 where a resistance layer 102b energized to generate heat is provided in a longitudinal direction on a base plate 102a and which is constituted so that a thermal fuse (temperature excessive rise preventing element) is allowed to abut on the base plate 2, and a fixing film 103 moving while sliding on the heater 102; and an unfixed image is heated and fixed by heat from the heater 102 through the film 103. At such a time, the, thermal fuse abuts on the outside of a minimum paper passing area on the base plate 102a. Since the thermal fuse is not set in a fixing nip area, the effect of heat absorption by the thermal fuse is not found on the image, and the excellent image without causing faulty fixing or having no shininess is obtained. Then, energizing the resistance layer 102b is interrupted by normally actuating the thermal fuse in the case of abnormal heat generation of the resistance layer 102b caused by the trouble of a temperature control circuit.

Title: Positioning jig for junction with heating process
Inventor: YAKOU TAKESHI
IPC: H01J9/18
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To precisely assemble an additional member to a plate member in the prescribed position by making a material of a structural body of an assembling member holding block by a material having the same coefficient of thermal expansion as that of the plate member. SOLUTION: Supporting bodies 12a, 12b of an assembling member holding block 10 are made of glass, and holding bodies 11 are made of stainless steels. Even if they are heated in a kiln at the temperature in the range of about 400 to 450 deg.C in a state where they are assembled on an assembling stand 20, the positions are not deviated in the A direction since the supporting bodies 12a and 12b perform the same thermal expansion as that of a glass plate 1. The assembling stand 20 is made of a stainless steel, however, the difference of thermal expansion is absorbed since the glass plate 1 and the assembling member holding block 10 are respectively and independently brought in contact with the strike parts 20b, 20c by springs 20.

Title: Pump
Inventor: KOIZUMI NOBORU
IPC: F04B17/04
Filed: 1980-01-23
Abstract: PURPOSE: To produce great torque with a low-capacity solenoid coil, by converting the attractive and repulsive force of a permanent magnet into reciprocating slide action.  
     CONSTITUTION: The tip of a cylinder 17 in an external case 14 is repeatedly magnetized from N to S and vice versa, as a solenoid coil 22 is applied with an alternative current. This change in polarity makes a permanent magnet 19 attached to a piston 18 attracted or repulsed in the cylinder 17. This reciprocating movement actuates a check valve 20 of the piston 18 to take in and discharge liquid or gas from a suction port to a discharge port. The reciprocating movement of the piston 18 utilizing the attraction and repulsion of the permanent magnet 19 can increase the driving force of the piston and also produce great torque for the pump, even when the capacity of the solenoid coil 22 is relatively small.
