Title: Electrophotographic recorder
Inventor: KONDO YOSHIHIRO
IPC: G03G15/05
Filed: 1988-09-26
Abstract: PURPOSE:To make recording speed quick by a method wherein toner having applied to a charged electrode is made to fly by Coulomb's force caused by potential difference between a surface potential of a photosensitive layer varied by light from a first light source and a potential of a charged electrode, and the toner is stuck to a recording medium. CONSTITUTION:An electric potential Vs of a surface electrode 5 is kept at a second electric potential V2, and an electric potential Vb of a back surface electrode 3 is kept at a second electric potential V2. First light 8a is radiated from a first light source 8, and a surface electric potential Vfp becomes almost the first electric potential V1. When the surface electric potential Vtp exceeds a threshold voltage Vth a that time, a toner image 9a is formed on a recording medium 7. The electric potential Vb of the back surface electrode 3 is switched to the second electric potential V2 by a switching means 10. Since a photosensitive layer 4 has become low resistant, the surface electric potential Vfp is switched to the second electric potential V2 for a short time. Then, the electric potential Vb is switched again to the first electric potential V1 by the switching means 10. Since the surface electric potential Vfp has been preliminarily switched to the second eleciric potential V2, a recovery term is extremely short to shift instantly to a stationary term (a).

IPC: G11B15/02
Filed: 1990-09-12
Abstract: PURPOSE:To enable dubbing of an address multiplex, control signal itself as it is by sending duty information of a reproduced address multiplex control signal to a transmission destination and using the sent duty information so as to control the duty of the control signal. CONSTITUTION:Figure (a) indicates a head switching signal switching heads A, B provided to a rotary drum opposite to each other by 180 deg. alternately, and figure (b) illustrates a reproduced video signal and figure (c) depicts a reproduced address multiplex control signal. Front ridges of the address multiplex control signals are spaced at a prescribed interval, but the tail end differs because the duty factor is modulated by the multiplexed information. Figure (d) shows a discrimination data outputted from a duty discrimination circuit 207 and figure (e) indicates a discrimination data resulting from delaying the discrimination data in the figure (d) by one frame at a delay circuit 209. The address multiplex control signal is in dubbing as it is with a comparatively simple means in this way.

Title: Power amplifier
Inventor: TOMARU FUMITO
IPC: H03F3/68
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To always provide optimum and stable combined output in accordance with the change in environment by adaptively controlling phase output based on the output levels of a plurality of power amplifiers and combined output level information. SOLUTION: Input signals from input terminals 11 and 12 are amplified to prescribed levels by power amplifiers 21 and 22. The output combined by a hybrid H: 8 and the outputs of the respective power amplifiers 21 and 22 are branched by directional separators 14, 71 and 72 and detectors 17, 51 and 52 extract respective pieces of output level information. The extracted output level information are sent to a phase control part 18, a phase shifter 5' is adjusted so that the combined output of the hybrid H: 8 becomes maximum and output 4 is obtained. The respective output phases of a plurality of power amplifiers are adjusted so that combined output becomes maximum.  Thus, stable relay amplification can be executed with a high gain even if a change occurs in the phase characteristics of the power amplifiers by a secular change, a temperature change, and the condition change of the installation of a cable.

Title: Optical reflecting mirror and production thereof
Inventor: OGATA KIYOSHI
IPC: G02B5/08
Filed: 1987-09-24
Abstract: PURPOSE:To prevent exfoliation of a reflecting film from a base material by forming the reflecting film on the base material and a protective film consisting of aluminum nitride on said film, then providing a mixed layer contg. the constituting materials of both the base material and the reflecting film near the boundary of said base material and film. CONSTITUTION:The reflecting film 6 is formed on the base material 4 by subjecting the base material 4 to vapor deposition of a reflecting film 6 material and irradiation of accelerated ions and the mixed layer 5 consisting the constituting materials of both is formed near the boundary face of both; thereafter, the base material is subjected to vapor deposition of aluminum and irradiation of accelerated nitrogen ions 28b in a vacuum, by which the protective film 10 consisting of the aluminum nitride is formed on the reflecting film 6. Since the aluminum nitride as the protective film 10 has a high light transmittance and thermal conductivity, local heating hardly arises even in the case of reflecting large-power light. In addition, the mixed layer 5 acts like a wedge and, therefore, the high adhesiveness of the reflecting film 6 to the base material 4 is obtd. Exfoliation of the reflecting film 6 is thereby substantially prevented.

Inventor: HASEGAWA KAZUO
IPC: H01L33/00
Filed: 1994-09-08
Abstract: PURPOSE: To provide a light emitting element driving circuit capable of simply reducing a useful power. CONSTITUTION: Driving means 10 operates in synchronism with an input single (a). Controlling means 11 also outputs control signals c1, c2 in synchronism with the input signal (a). Voltage converting means 12 comprising a charge pump circuit among a power source 8, the driving means 10 and LED's 2 also operates according to the control signals c1, c2. Therefore, it operates in synchronism with the input signal (a). When the input signal (a) is low (non-light emitting), the voltage converting means 12 charges capacitors connecting in series from the power source 8, and when high (light emitting), a connection of internal capacitors is converted to be in parallel to set a voltage to be 1/2, consequently discharged to the side of the LED's 2. Therefore, power efficiency is high.

IPC: G03B21/132
Filed: 1992-09-09
Abstract: PURPOSE:To prevent adverse effect from being exerted on a projected image by preventing the bend of a lens holding frame body for a projecting lens constituting a projecting head, the deviation of the optical axis of the projecting lens caused by secular change and the distortion of the projecting lens. CONSTITUTION:The projecting lens 46 is held in the forked lens holding frame body 52 integrally formed at the tip part of an arm 40.
