Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor excellent in electrophotographic characteristics such as sensitivity, less liable to optical fatigue and ensuring satisfactory productivity because of a long pot life of a coating soln. for the photosensitive layer by incorporating a mixture of specified hydrazone, butadiene and styryl compds. as an electric charge transferring material into a photosensitive layer. SOLUTION: When a photosensitive layer contg. an org. photoconductive material is formed on an electrically conductive substrate to obtain an electrophotographic photoreceptor, a mixture of a hydrazone compd. represented by formula I, a butadiene compd. represented by formula II and a styryl compd. represented by formula III is incorporated as an electric charge transferring material into the photosensitive layer. In the formula III, R<1> -R<6> are 1-4C alkyl and they may be the same or different. Since the mixture of the three compds. is used, defects in the case of use of one of the compds. are compensated. The hydrazone compd. accounts for 40-95 wt.% of the entire electric charge transferring material, the butadiene compd. accounts for 1-50 wt.% and the styryl compd. accounts for 4-50 wt.%.

Title: Information recording medium and its manufacture
Inventor: KAWANISHI YOSHITAKA
IPC: G11B7/24062
Filed: 1994-09-30
Abstract: PURPOSE: To manufacture the high density and high accuracy recording medium through reducing the dullness or unsharpness of the periphery of each of the record pits of the medium and to provide the manufacture of the medium. CONSTITUTION: This medium is provided with a multilayer film 1B12 which consists of at least two layers and is formed by alternately laminating high refractive index layers 1B1 and low refractive index layers 1B2 one by one in that order repeatedly on a transparent substrate 1A, and a resin film IC laminated on this multilayer 1B12 . At least one refractive index layer of the high refractive index layers 1B1 and low refractive index layers 1B2 has hole- like record pits 1P which are formed by an etching method after forming the multilayer film 1B12 .  The incident laser beam on each of the pits 1P is reflected by a reflection layer provided at the bottom of the inside of the pit 1P and a phase difference between this reflected laser beam from the pit 1P and another reflected laser beam from an unrecorded part is generated to reduce the quantity of the reflected light by the interference. Thus, this medium enables reproduction by the push-pull method.

Title: Controller for plural actuators
Inventor: IWASAKI MICHIO
IPC: F15B11/22
Filed: 1987-09-21
Abstract: PURPOSE:To prevent plural actuators from being operated by external force by providing a differential valve to stop the operation of the plural actuators caused by an oil flow through the plural actuators when a directional control valve is in a neutral position. CONSTITUTION:When a directional control valve 3 is in a neutral position A0 and external force is applied to an actuator 4, a pressure is generated on a bottom 4B so as to shift a differential change-over valve 101 to a position B2. A differential change-over valve 201 is shifted to a position C1 due to said shift. In this case, since outlet ports 106, 206 of a pipeline 9 to a bottom chamber 5B within one actuator 5, are connected/disconnected respectively to/from inlet ports 102, 202 in positions B1, C1 of differential change-over valves 101, 202, oil on the bottom 4B of the other actuator 4 can not flow into the bottom 5B of said actuator 5.

Title: Prevention of adhesion of foreign matters
Inventor: SAITO AKIO
IPC: H01L21/304
Filed: 1992-09-04
Abstract: PURPOSE:To prevent adhesion of foreign matters in a hydrofluoric acid water solution by adding a substance controlling zeta potential of foreign matters and a substrate to a hydrofluoric acid water solution. CONSTITUTION:HF: H2O=1:19 solution 2 is adjusted and an anionic interface activator is added into a layer to be cleaned. Since absolute values of zeta potential of both of Si particles and an Si substrate are small (approaching zero) in a hydrofluoric acid, and electrostatic repulsive force between foreign matters and the substrate comes to be lowered so as to facilitate adhesion of foreign matters. Adhesion of the anionic interface activator to the hydrofluoric acid water solution lowers zeta potential (increases absolute value) of foreign matters and the substrate. Thereby, electrostatic repulsive force between foreign matters and the substrate increases so as to prevent adhesion of foreign matters.

Thereby, the PLA is provided w]th the means to substitute the true for the false of the OR plane and the means to substitute the true for the false of the output. In other words, discharge MOS transistors (80-86) are connected to word lines (61-63), and an inverter 93 is provided additionally, As a result, the transistors (80-86) corresponding to active word lines (61-63) can be energized, and either the bit lines (110-112) is discharged, then, the output resistant to the crosstalk can be obtained at inverters (97-99).

Title: Electric power controller
Inventor: ESATO SATORU
IPC: G05F1/10
Filed: 1984-11-09
Abstract: PURPOSE:To minimize electric power consumption by adopting such a control system that a DC electric power source is turned on only when a system electric power source is turned on and off. CONSTITUTION:When an electric power source part 3 receives the instruction for turning on the electric power source, it turns on the DC electric power source supplied to a system electric power source control part 5, and supplies the DC electric power source to the system electric power source control part 5 through an electric wire 15. When the DC electric power source is decided, the electric power source part 3 transmits the decision signal of the D electric power source of the system electric power source control part 5 to its own electric power source control part 4 through a signal line 14. At this point, said part 4 transmits instructions for turning on/off the system electric power source and activating to the system electric power source control part 5 through a signal line 16. When the self electric power source control part 4 detects the system electric power source sequentially turning on/off termination, it reset the held instructions for turning on/off the system electric power source, and transmits the latter instruction to the electric power source part 3. Thus, if turning on and off the electric power source of an electric power source controller is controlled, useless electric power can be saved, and the reliability of said controller can be improved.

Title: Vapor growth device
Inventor: KANO TSUNEO
IPC: H01L21/205
Filed: 1990-09-07
Abstract: PURPOSE:To enable a uniform film to be grown by providing a jet-out port for spraying a reaction gas toward a central part of the wafer perpendicular to the wafer surface for each wafer. CONSTITUTION:When performing vapor growth, a wafer 3 which is placed on a boar 4 is inserted into a reactor core tube 2 which is heated by a heater 1 and a reaction gas is introduced from a gas introduction port 5 and is sprayed toward a central part of the wafer 3 from a jet-out port 9 and the reaction gas flows toward an outer-periphery part while being subjected to reaction from a central part of the wafer 3 as shown in a gas flow 6 so that gas concentration at the outer-periphery part becomes thinner than the central part. However, since the temperature at the outer-periphery part is higher than that at the central part, difference in growth speed of the film becomes smaller, thus enabling a uniform film with less scattering of film thickness distribution within the wafer surface to be grown.

Filed: 1986-10-06
Abstract: PURPOSE:To always execute refresh by an appropriate timing by preparing not only a first clock but also a second clock for executing a refresh operation, and also, controlling them so that an access can be executed preferentially, when timings of both operations have been superposed. CONSTITUTION:An input data DI supplied to an input terminal 2 is synchronized with an external clock CK1 supplied to an input terminal 4 in a D-type flip-flop 3. Subsequently, the synchronized input data DI is synchronized with an internal clock CK2 obtained from an internal clock oscillator 6, in a DFF5, and takes a timing of refresh of a DRAM1. That is to say, in case a refresh timing by a signal SRT and a rise detecting point of the external clock CK1 by a signal SCK have been superposed, the signal SCK is brought to priority, and also, a state of the signal SRT is held, and after write and read-out have been ended, the refresh can be executed. In this way, even if a frequency of the external clock CK1 is varied, the refresh operation can always be executed in a prescribed period.
