Title: Analyzer for liquid sample of patient
Inventor: REIMONDO FURANSHISU JIYAKUBOUI
IPC: G01N35/00
Filed: 1994-04-18
Abstract: PURPOSE: To count remaining test elements accurately by reciprocatively installing a plunger inside a housing, wherein the plunger is to move test elements distributed in the liquid of a patient. CONSTITUTION: A pinion 144 and rack 146 drive a housing 120 so that a plunger head 110 is brought in contact with a test element E. When the housing 120 starts moving up- and-down, a flag 140 moves from a sensor 142. At this point, a computer 143 counts advancing runs of the pinion 144 caused by a step motor. Even after the head 110 contacts the element E, the pinion 144 continues driving so that the stack of elements E is press-contacted to a platen. Then a flag 116 shuts off the beam of light between a diode 134 and a sensor 136, and a signal is transmitted to the computer 143 to stop the pinion 144. The computer 143 calculates the number of remaining elements E from the count of advancing runs made by the step motor.

Title: Differential device
Inventor: TERAOKA MASAO
IPC: F16H48/32
Filed: 1990-03-29
Abstract: PURPOSE:To perform reliable support, to prevent leakage of the pressure at a seal part, and to improve reliability by locating a pressure passage, running to an actuator, on the inner side in the radial direction of a bearing for supporting a differential case. CONSTITUTION:Since the communicating part and the seal part of a pressure passage 69 between a case 25 and a support part 57 are arranged on the inner side in a radial direction of a bearing 31 for supporting a differential case 23 to the case 25, reliable support is carried out and production of swinging is decreased, resulting in prevention of leakage of oil and ensurance of excellent reliability. Further, since a peripheral member is lubricated by means of transmission oil, even when oil leaks, no adverse influence is exercised on the peripheral member. Since the pressure passage 69 is formed by utilizing a support part 57 of an axle 7, a cost for newly mounting the support part 57 is prevented from an increase. Since the support part 57 is not protruded axially outwardly of the bearing 31, built-in properties are not lowered. Further, since the oil passage 69 is not formed in the axle 7, the number of seal spots is reduced and reliability is improved thanks to reduction of the number of seal spots.

Title: Auto-winder of camera
Inventor: IGUCHI SUSUMU
IPC: G03B17/42
Filed: 1978-06-29
Abstract: PURPOSE: To supply current to a time constant circuit through a hold switch which maintains a close state while a motor is making film winding operation for one frame and let operation such as stop of current supply to the motor take place when the output thereof reaches the specified value.  
     CONSTITUTION: When a power source switch SW 1  is turned ON and SW 3  is closed, a pulse is transmitted to a capacitor C 1  and base current is flowed to a transistor Q 4  to turn it ON through a diode D 2 , causing a relay RY to energize to supply power to a motor M. As the motor M revolves, the hold switch SW 6  interlocking to the the revolution goes ON to charge a capacitor C 2 . As the shutter is released, a memory switch SW 6  switches to the storage side and the base potential of Q 4  becomes equal to the emitter potential and Q 4  turns OFF to de-energize the relay RY thereby breaking the power supply to the motor M. At this time, Q 1  turns OFF and the charging charges of the C 2  are discharged. At the same time Q 2  turns OFF to flow current to an LED, thus displaying the shutter under opening. This current turns Q 3  OFF and similarly maintains Q 4  at OFF.

Abstract: PURPOSE:To reduce an equipment cost while the sectional accuracy of material is improved by using a rolling will wherein a four-roll mill is arranged at the final stand of a group of finishing roll mills constituted of roll mills of plural stands. CONSTITUTION:The rolling will is constituted of a group of two-roll mills in which two-roll mill stands S1-Sn of (n) stands are arranged alternately at phase of 90 deg. and a four-roll stand Sn+1 which is inclined by 45 deg. to the directly before stand Sn as the final stand. Two-roll mills Sn-2, Sn-1, Sn from three stands to one stand before the final stand and the final four-roll mill Sn+1 compose a group of finishing rolls.

Consequently, a spread of the material can be restrained.

Title: Radiation resistant paper and production thereof
Inventor: YAMAZAKI HIDEHIKO
IPC: D21H19/10
Filed: 1994-03-28
Abstract: PURPOSE: To obtain paper resistant to radiation which is used for printing, processing or sterilization by impregnating paper with a dilute solution of a radiation-reactive monomer having vinyl groups. CONSTITUTION: A radiation-reactive monomer bearing vinyl groups such as tetraethylene glycol dimethacrylate is dissolved in a non-aqueous solvent such as ethanol or an aqueous solvent to prepare its dilute solution. Then, the paper is impregnated with the dilute solution on or after the papermaking. The surface tension of this dilute solution is made lower than the critical surface tension of the fibers constituting the paper to allow the monomer to be sufficiently soaked in the gaps between filaments in the paper, then dried to remove the solvent to give this paper which holds almost all of the spaces between fibers in the paper layer. This paper resists electric beams or gamma rays applied for printing ink hardening or sterilization of the products packed with the (processed) paper without deterioration.

Filed: 1989-03-30
Abstract: PURPOSE:To automatically turn off a driver by comparing the drain voltage of the FET of the driver in a charging circuit with a supply voltage in a chip, controlling the gate voltage of the driver, and charging a load circuit up to the supply voltage inside the chip. CONSTITUTION:In an initial stage, a control signal SEP is at an 'L', transistors (TR) Q10 to Q12 are turned off, and a current mirror CM is not operated. Since Q23 is turned on, a terminal N5 is precharged to VCC(EXT), and Q20 is turned off. In the initial stage when an output SAP of a charging circuit 33 is precharged to 1/2VCC (IIN), the through current of the charging circuit does not exist. When the signal SEP is changed to an 'H', Q10 to Q12 are turned on, an input terminal N1 of the CM decreases below the reference current of a terminal N4, the CM is operated, and the charge to the load circuit connected to the SAP is started. When the potential of the SAP increases higher than the internal supply voltage VCC (INT), the CM raises the N5, the driver Q23 is turned off, and the charging is stopped.
