Title: Lubricant and wire for welding
Inventor: ARAI TOSHIO
IPC: B23K35/40
Filed: 1979-12-12
Abstract: PURPOSE:A lubricant which is specified of the kinds of compounding components and their componding ratios, which does not cause the problem of entry of hydrogen, and hindrances to current supply characteristic and weld metal, and which considerably enhances feed characteristic and also provide excellent effect in drawing. CONSTITUTION:This lubricant consists in suspending 0.1-10pts.wt. a fluorine-base low polymn. degree compound of 2,500-10,000mol.wt., and 0.1-20pts.wt. graphite and/or MoS2 in a volatile solvent such as trichloroethylene. With the mol.wt.  below said range, satisfactory drawability and feed characteristic are not obtainable, and above said range, dispersibility is poor and the lubricant cannot stick uniformly on wire surface. The graphite and MoS2 to be used in combination are fine  powder of <=3mu grain size to obtain a stable suspension. In the case of the one for  coating, it <=1mu is desirable in consideration for the effect on current supply characteristic and deposited metal. If the weight ratios of the components are set at the  above-described ratios, they stick at the former/the latter =0.5-99, and if pickup  is made adequate, sufficient lubricity is obtained.

IPC: H01H50/56
Filed: 1993-06-30
Abstract: PURPOSE:To make molding powder hardly generate a CONSTITUTION:In a leaf sprung support device having a support base 1 having a regulating part 11 formed from a molding material a blade spring 21 inserted to the regulating part while one surface 21b side is slid on it, and supported by and fixed to the support base 1, the leaf spring 21 is formed on the top end position in the direction where a bent piece 21e bent on the other surface 21d side is inserted to the regulating part 11. Thus, since the round bent outside part of the bent piece 21e is inserted while the one-surface 21b side is slid onto the regulating part 11 formed by the molding material even when the drawing roundness of the rupture surface formed at drawing is laid in an extremely small and sharp state because of the relatively small thickness of the plate having spring property, the molding powder is difficult to generate.

Title: Ccd drive circuit
Inventor: YAMAMOTO TOSHIROU
IPC: H01L21/339
Filed: 1978-12-26
Abstract: PURPOSE:To reduce the occupation area with addition of a resister and a MOSFET to the 2-phase drive circuit. CONSTITUTION:A series resister R is inserted between a drain d1 and a capacitor C2 of a MOSFET Q1 and a MOSFET Q5 is connected to a gate g3 of a MOSFET Q3. When the voltage of the input terminal I is H, the MOSFET Q1 and Q4 turns on immediately, the incoming current (a) of the capacitor load rises very sharply. Here, the MOSFET Q5 is for the gate grounding of the MOSFET Q3. The moment the input voltage turns to L, FETS Q1, Q4 and Q5 are turned off so that the falling current (b) changes slowly. In this case, if a sufficiently large resister R is selected, the value of the capacitor C2 can be reduced noticeably as the charge time constant of the capacitor C2 is tau C2R. With a less occupation capacity, the circuit can be miniaturized, thus advantageous in the placement on the same substrate with the CCD in the form of a chip.

Title: Direct recording system
Inventor: FUJII TADASHI
IPC: G03G15/00
Filed: 1978-12-26
Abstract: PURPOSE:To eliminate ground stains, enhance image density and increase recording speed by holding a fixed spacing between the developer carried on a counter electrode and a recording sheet and applying ultrasonic vibrations to the counter electrode. CONSTITUTION:The spacing between a recording electrode 5 and a counter electrode 6 is maintained at a value nearly equal to the paper thickness of a recording sheet S and the developer 7 carried to the counter electrode maintains a fixed spacing without making contact with the sheet S. A vibration energizing means is taken to the counter electrode 6 and is bonded with an ultrasonic wave vibrator 10. Excitation current is intermittently supplied to the vibrator 10 from an ultrasonic wave generating source 12 in synchronization with the recording operation. The ultrasonic wave vibrations cause the surfaces of the developer 7 to wave and the wave tops are torn off by the image signal and are directly deposited on the sheet S side, whereby toner images are formed. Since the developer does not contact the sheet, there are no ground stains and the recording speed may be increased.

Filed: 1981-10-14
Abstract: PURPOSE:To obtain a clock rate error signal in a disc reproducing device by detecting a signal having the maximum or minimum pulse width out of continuous signals, and after converting said signal into the voltage proportional to the pulse width, detecting an error between the converted voltage and a reference one. CONSTITUTION:A motor 1 is rotated by starting voltage 7 and a pick-up 5 traces on a disc 2. A readout signal is supplied to monostable multivibrators 12, 13 and clears a counter 42 through an OR gate 14. The counter 42 outputs a signal proportional to a signal changing point interval just before said clearing operation. A digital comparator 47 compares the I/O values of a D type FF 43 to enter the contents of the counter 42 into the FF 43 and store the number of clocks proportional to the pulse width. A D type FF 44 inputs the maximum value counted by the counter 42 and a digital comparator 200 digitally compares the contents of the FF 44 with a previously fixed reference value. Its error output is converted by a D/A converter 49 and returned to the motor 1 so that the clock rate is fixed.
