Title: Current supply circuit
Inventor: TOKUNAGA MICHIO
IPC: G05F1/56
Filed: 1981-01-28
Abstract: PURPOSE:To decrease the power consumption of a current supply circuit, by converting the output voltage of a DC-DC conversion circuit into a voltage between a sum of a voltage drop across a load resistor plus a specified value of an operating voltage of a DC power supply circuit, and a power supply voltage, through the use of the DC-DC conversion circuit. CONSTITUTION:When a current Is proportional to a load current flows to a comparison terminal of an error amplifier COMP, an output voltage VOUT of a DC-DC converting circuit 9 changed depending on the current Is, and when the current Is increases, the voltage VOUT is decreased, while the current Is decreases, the voltage VOUT is increased. In this operation, when an output voltage of the circuit 9 is between a sum of a specified value of the operating voltage of a DC supply circuit 8 plus a voltage drop across a load resistor, and a power supply voltage VBB, the power consumption of a current supply circuit 6 is reduced.

IPC: H05K3/28
Filed: 1992-01-23
Abstract: PURPOSE:To provide a polyimide pattern without unwanted film left at a development step by treating a copper wiring layer with an aqueous solution of sodium hydroxide, forming photosensitive polyimide precursor film on the copper wiring layer, exposing the wiring layer to a pattern of light and developing it, and heat-treating the developed pattern.

A solution of a photosensitive polyimide precursor is spread on the copper wiring pattern, dried, exposed, and developed. The developed pattern is rinsed with alcohol; thus a polyimide precursor pattern is obtained. No unwanted film remains on through holes at the pattern in this step. After the precursor pattern is thermally cured to obtain a polyimide pattern, the copper oxide on the through holes is etched away.

Title: Coil device
Inventor: TSUKA KAZUMASA
IPC: H01F5/02
Filed: 1995-01-26
Abstract: PURPOSE: To increase the number of turns of a coil without lowering dielectric strength. CONSTITUTION: In a coil device which is provided with an iron core 1, an insulating tape 2 which is pasted with and wound up around the middle part 1a of the iron core 1, a coil 4 wound up on the insulating tape 2 and a coil frame 3 formed on both ends of the iron core 1 so as to regulate a coil winding pace in the longitudinal direction, the coil frame 3 is formed in such a structure that it may cover both ends 2d along the wining direction of the insulating tape 2.  Therefore, since the coil 4 is wound up around the iron core 1 by way of the insulating tape 2 whose thickness is reducible than a molded body, the number of turns of the coil is increased while both ends of the insulating tape 2 in the winding direction is buried inside the coil frame 3, which prevents the generation of a separated space in a boarding area with the coil frame 3 and maintaining an insulation distance between the coil 4 and the iron core 1 with its internal embedded area.

Title: Developing device
Inventor: NAKAMURA TOSHIHARU
IPC: G03G15/09
Filed: 1986-01-21
Abstract: PURPOSE:To obtain a simple developing device which can prevent deterioration of a developing agent caused by the difference of copies in size and improve density variation of copies, by making magnetic fields different from each other between an area where developing agent consumption is high and another area where the consumption is low. CONSTITUTION:This developing device is designed so as to prevent deterioration of a developing agent by making the magnetic circulation of the developing agent in an area where developing agent consumption is low weak in degree and the peak position of the magnetic pole (Pole S2) of a fixed magnet 3 controlling the circulation of a magnetic developing agent 4 in a hopper in the axial direction of a sleeve is changed. This magnetic pole S2 is formed so that the magnet roll 3 can have different magnetic-pole constitutions which are shifted in the peripheral direction between the central part and both end sections. Since the inter-magnetic-pole angle between both end sections of the magnetic pole S2 and another magnetic pole N1 is larger than that at the central part of the magnetic pole S2, the circulating speed of the developing agent in a hopper at both end sections of the nonmagnetic sleeve 2 becomes slower than that at the central part.

Inventor: AKAMATSU MASAHIKO
IPC: H03K17/73
Filed: 1981-01-28
Abstract: PURPOSE:To improve the relation among a turn-on delay time, dV/dt performance and control sensitivity, by controlling a semiconductor swith element with a low voltage obtaned from a voltage division means toward conduction and shortenting the control electrode of the said element through an auxiliary semiconductor switch. CONSTITUTION:When no input IF is present, no light is radiated on a phototransistor (TR)6 and the  TR is nonconductive. Thus the current in the voltage  division means 11, 14 flows to an auxiliary TR13 as shown in dotted arrows,  the TR13 shortens the control electrode pair of an SCR1 and the dV/dt performance can be increased. When the input IF is given, the TR6 turns on and  the current flows to the control electrode of the SCR as shown in the arrow 16. In this case, a low voltage power is supplied to the TR6 from the means 11, 14, then at least, either one of transmission speed and sensitivity can be improved.

Title: Zoom lens system capable of manual and automatic focusing
Inventor: MASUMOTO HISAYUKI
IPC: G02B7/28
Filed: 1982-01-27
Abstract: PURPOSE:To obtain a small size zoom lens system of zooming ratio 3-6 by changing magnification by changing distance between the first and second groups and distance between the second and third groups and moving the first group in manual focussing and moving rear lens groups in case of automatic focussing in a zoom lens system that starts with the first group of positive refraction and the second group of negative refraction. CONSTITUTION:The system starts with the first groupIof positive refraction and the second group II of negative refraction from the subject side successively. Magnification is varied by changing air distance between the first and second groups and air distance between the second and third groups. In manual focussing, the first groupIis moved in the direction of optical axis independently, and in case of automatic focussing, a lens group LF provided in the rear of the lens system is moved. Accordingly, no mechanical interference takes place between manual focussing and automaic focussing. Deterioration of aberration and enlargement of the lens system are prevented by making the focal length f1 of the first group and the focal length fF the lens group LF 0.3<fW/f1<0.6, 0.07< fW/fF<0.4 (fW: shortest focal length of the whole system).
