Patent JP-H0327579-A (JP)
Title: Light emitting diode drive circuit
Inventor: YAGI KEIJI
IPC: H04B10/2507
Filed: 1989-06-24
Abstract: PURPOSE:To perform a high speed drive and to prevent current consumption from varying by adding a peaking current to a driving current at the time of light emission, feeding it in parallel with a LED after a light pulse output is risen, and shortcircuiting both ends of the LED at the time of extinguishing a light emission. CONSTITUTION:A transistor Tr 14 is turned ON simultaneously upon supply of a normal current ID at the time of light emission of a LED 2, and a peaking current IP is fed to the LED 2. As a result, the rising time of a light pulse output 2a is largely shortened. If the Tr 14 is turned OFF after the output is risen, a current IQ corresponding to a current IP flowing to the Tr 14 is fed through a Tr 9 by the operation of a constant current circuit 23. Since the Tr 9 is provided in parallel with the LED 2, the current IQ does not pass the LED 2. Accordingly, since current consumption of a whole circuit is not varied, an erroneous operation by a noise is not generated. When the LED 2 is extinguished, a TR 15 is turned OFF, a Tr 16 is turned ON, and no current ID flows to the LED 2. In this case, a Tr 13 is turned ON, and the LED 2 is conducted at both ends.

Title: Shock relaxing clutch mechanism
Inventor: MIYAGI YOSHIO
IPC: F16D23/10
Filed: 1981-10-09
Abstract: PURPOSE:To effectively moderate a shock at coupling, by driving a driven side in preliminary rotation immediately before the coupling operatiopn and performing the coupling operation under a condition in which a relatively rotating speed of driving and driven sides in a positive clutch is decreased. CONSTITUTION:A prime moving shaft 22, gear 42, gear 61 and input shaft 71 of an auxiliary rotary driving mechanism part in a positive clutch 1 are always continued rotating. While a one-way rotary transmission clutch 3, built in a gear 41, is constituted such that a driven shaft 21 and the gear 41 are rotated in an equal direction, further rotation of the gear 41 is transmitted to the driven shaft 21 by action of the one-way rotary transmission clutch 3 only when a rotary speed of the driven shaft 21 is in a condition tending to decrease lower than a rotary speed of the gear 41. After coupling, when rotation of the driven shaft 21 is faster than rotation of the gear 41, the gear 41 and the driven shaft 21 are in a slipping state in the one-way rotary transmission clutch 3.

IPC: B41J13/00
Filed: 1989-06-23
Abstract: PURPOSE:To remove tilting and transverse displacement of a sheet forcedly pressed to a sheet guide means until the sheet is brought into contact with a roller by once retracting the sheet, inserted in a conveying means, to a position, where the sheet is not brought into contact with the roller in a sheet transfer amount detecting means, and again advancing the sheet. CONSTITUTION:A sheet 13, which is a conveyed unit, is pressed to an opposite surface to a vibrator-secured surface in an elastic unit 20, and by applying frequency voltage from a power supply means 24 to a vibrator 19 to form an advancing vibratory wave in a manner possible to switch it in both normal and reverse directions in the elastic unit, thus the sheet is given transfer-feed force and conveyed by a vibratory surface in which the advancing wave is formed. Here by controlling the power supply 24 with a control means CNT to switch the direction of this advancing wave, the sheet is once retracted to a non-contact position with a roller 23 in a sheet transfer-feed amount detecting means and again advanced. In this way, until the sheet is brought into contact with this roller 23, the sheet is forcedly pressed to a sheet guide 21, and conveyance of the sheet is stabilized by removing its tilting and transverse displacement.

Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device and a package, that can prevent a bonding impact from causing concentration of stress and can disperse the stress so as to mount elements and wires without damage, by setting at least one of layers between pad electrodes, elements, and wires with an average evenness of 0.5 μm or less, or controlling a capacity ratio of an interconnection layer and an insulator. SOLUTION: Each surface of electric insulating layers 4 (a, b, c) is set with an average evenness of 0.5 μm or less between terminal electrodes 2 and elements 5. The average evenness is achieved by, for example, a chemical and mechanical polishing. This arrangement makes it possible to reduce concentration of stress especially on a part having a large unevenness due to a bonding impact so as to prevent damage on the elements disposed below. Further, a capacity ratio of a wire and an insulator is controlled so as to prevent concentration of stress upon bonding and mounting. Consequently, it is possible to mount the elements and the wires without damage.

Filed: 1983-09-05
Abstract: PURPOSE:To improve an electromagnetic conversion characteristic and durability with a magnetic recording body consisting of providing a magnetic layer dispersed with ferromagnetic powder in a binder by adding polyester having a carboxylic group at least at one terminal of the molecular chain to the binder. CONSTITUTION:Polyester of about 200-5,000mol.wt. having a carboxylic group at least at one terminal of the molecular chain is incorporated into a binder. The polyester is obtainable by using excessively dicarboxylic acid in the stage of condensing polyol and dicarboxylic acid. If the mol.wt. of the polyester is smaller than about 200, the adjustment of the mol.wt. is difficult and synthesis is difficult. If said wt. is larger than about 5,000 no improvement is observed in the dispersibility of ferromagnetic powder and is therefore said wt. is undesirable. The mol.wt. of the polyester is more particularly preferably about 400- 1,000. The polyester is used at about 0.1-10wt%, more preferably about 1- 5wt% by the weight of the ferromagnetic powder.

Title: Focusing controller
Inventor: MIYASHITA ATSUSHI
IPC: G02B7/28
Filed: 1983-09-07
Abstract: PURPOSE:To stabilize the operation of a focusing controller by adding a means which stops the focusing operation when a camera is confronted with an object having low contrast. CONSTITUTION:A drive starting pulse is outputted from a driving circuit 7 so as to drive a sensor 3, so the Q' terminals of D-FFs 20-1 and 20-2 are held at the level of logic ''1''. Then, the control signal from a control signal generating circuit 9-7 places AND gates 9-3a and 9-3b in readiness for use, and a new binary video signal A is inputted to the CK terminals of D-FFs 20-1 and 20-2. If the binary video signal A is all logic ''0'' or ''1'' because the subject is low in contrast and entirely black or white, neither the CK terminals of the D-FFs 20-1 nor 20-2 has a change of a logical signal from ''0'' to ''1'', so the Q' terminals are still at logic ''1'' and a log contrast signal S goes up to the logic ''1''. Consequently, the driving of a lens is stopped.

Title: Fixing abnormality detector for copying machine
Inventor: KIKUCHI HIDEO
IPC: G05D23/19
Filed: 1991-06-10
Abstract: PURPOSE:To detect even such abnormality that occurred when no power is supplied to a fixing heater by storing the temperature when the supply of power is cut off to the heater and then detecting the temperature when the power is supplied again to the heater so as to compare both temperatures with each other. CONSTITUTION:When a power supply is turned on, a microcomputer 1 sets the mode of a peripheral LSI. Then the microcomputer 1 reads the present time out of a clock IC and stores it in order to check the abnormality of a fixing part and calculates the time when the supply of power is cut off to a fixing heater from the time when the supply of power is cut off. Then the fixing temperature of the present time point is estimated based on the fixing temperature set when the power supply is turned off as well as the calculated OFF time of the power supply. If the detected temperature is extraordinarily lower than the estimated fixing temperature, the abnormal state of the fixing part is shown and a copying operation is inhibited. If the detected temperature is extaordinarily lower then the estimated level, the short circuit in a thermistor 14 is detected. Then an abnormal state is shown if the fixing temperature is lower than the temperature set when the power supply is turned off and does not reach a prescribed level even after a prescribed time.
