Patent JP-H049703-A (JP)
Title: Angular displacement sensor
Inventor: KURISUTOFUAA JIENTAIRU
IPC: G01D5/16
Filed: 1990-04-27
Abstract: PURPOSE:To generate a signal related to the amount of the angular displacement of an object correctly by providing a detecting means with a substance having an electric resistance which changes as a function of the angular displacement, and forming the substance of a conductive ink adhered onto a base material. CONSTITUTION:A conductive ink sensor utilizes a conductive ink 32 adhered onto a base material 34. The ink 32 generally has carbon particles in a coupling material. When the base material 34 is bent to turn the ink 32 outside, two physical reactions within the ink 32 change the electric resistance of the ink. According to the first reaction, the distance between the conductive carbon particles is enlarged owing to the expansion of the ink 32, resulting in an increase of the electric resistivity. This reaction occurs also when the base material 34 is bent to turn the ink 32 inside of the bending part, whereby the resistivity is decreased since the distance between the particles is reduced. According to the second reaction, when the ink 32 is at the outside of the bending part, a very thin crack is formed in a direction intersecting the longitudinal direction of an angular displacement sensor. If the bending is increased, the width of the crack becomes larger, thereby further increasing the electric resistance.

Title: Image forming device
Inventor: MURAHASHI TAKASHI
IPC: B41J2/44
Filed: 1987-05-11
Abstract: PURPOSE:To obtain a light deflector with optimum size by specifying the scanning direction length of a reflecting mirror included in a light deflector for deflecting an optical signal modulated from an image signal and writing image information in a recording body. CONSTITUTION:An optical signal modulated from an image signal is deflected by a light deflector in a deflecting system 300 and an electrostatic image is formed on an image forming body 11. Since the optical signal beam is deformed to a lateral elliptical shape at the time of passing a cylindrical lens 33, the use of a rectangular mirror in a main scanning direction is required for the reflecting mirror in the deflecting system 300. The horizontal direction length D of the reflecting mirror is selected based on an inequation I under the consideration of the focal distance of a scanning lens 42, the diameter of a beam spot, scanning width, and so on. Consequently, a light deflector having the optimum size matched with a recorder can be formed and economical efficiency and image forming efficiency can be improved.

Title: Resistance value trimming of thermal head
Inventor: YOSHIIKE NOBUYUKI
IPC: B41J2/35
Filed: 1990-04-26
Abstract: PURPOSE:To trim the resistance value of a resistor in a short time by dividing the resistance value of a thermal resistor for each dot within a specified range and applying a constant pulse voltage for each divided block. CONSTITUTION:A dot resistance value is divided into (1) a value of +15% or higher, (2) a value of +15% to +10%, (3) a value of + or -10% and (4) a value of -10% or lower. Then the dots of (1) are uniformly trimmed by -20% and the dots (2) are uniformly trimmed by -10%. As a result, a specified dot resistance value distribution is obtained. If dots with a resistance value of +30% or higher are present, the dots cannot be trimmed within a tolerable trimming range. In addition, all the dots can be easily trimmed to a tolerable range by two-step trimming method, if the resistance value distribution range if equal to -10% to +30% of a target resistance value.

Title: Method and device for impurity diffusion
Inventor: IWAMATSU SEIICHI
IPC: H01L21/223
Filed: 1980-08-20
Abstract: PURPOSE:To improve uniformity in a wafer and between wafers by a method wherein in a device being in depressurized condition at less than one atmospheric pressure and is heating substrates, an imprity soutce consisted of a gaseous body or evaporated gas from a liquid is introduced and is made to diffuse. CONSTITUTION:The plural wafers 3 put on a jig 2 are accomodated in a quartz tube 1, and are heated at the prescribed temperature. In the depressuized condition of the inside of quartz tube by a vacuum pump 5, the impurity gas is supplied from an evaporator 7 of a liquid diffusion source (BBr3, etc., for example) held at a constant temperature with an electronic cooling and heating devidce 6, for example. Because the inside of the quartz tube is held at the depressuized condition and impurity gas in the quartz tube has the large average free path, the impurity gas collides with the respective wafers equally and diffuses uniformly. Accordingly deteioration like a solid diffusion source is not generated on the diffusion source, and intermixing of contamination can be also prevented.

Filed: 1982-06-29
Abstract: PURPOSE:To set easily fail-safe of a controlled system, by providing the second time limiting means whose time limit is longer than that of the first time limiting means for monitoring an operation of a CPU. CONSTITUTION:In case of a temporary malfunction of a CPU 1, it is detected by the first time limiting device 3, the CPU is reset to its initial start state, and as soon as the cause of the malfunction is eliminated, it is reset to its normal state. Also, when an output of the second time limiting device 8 is generated, a control signal of the CPU is applied to a controlled system 5, but since the time limit of the time limiting device 8 is longer than that of the time limiting device 3, no output is generated in the time limiting device 8 in case of a malfunction of the CPU. Therefore, an erroneous control signal from the CPU in which a malfunction is caused is not applied to the controllled system 5. Accordingly, fail-safe of the controlled system 5 can be set easily.

Abstract: PURPOSE:To perform a normal read-write operation in a self-system by inputting the driving current signal of the head positioning means of one system to the power amplifier of the other system through a mutual intervention suppressing circuit composed of a secondary low-pass filter and a primary high-pass filter. CONSTITUTION:A signal at one end of a current detecting resistance 28a connected in series to a motor coil 25a is inputted to a power amplifier 22b of the other system through a mutual intervention suppressing circuit 23a. In the same way, a signal at one end of a current detecting resistance 28b connected in series to a motor coil 25b is inputted to a power amplifier 22a of the other system through a mutual intervention suppressing circuit 23b. Consequently, when the driving current signal of one system is inputted to the power amplifier of the other system as a mutual intervention suppressing signal composed by the cascade connection of the secondary low-pass filter with the primary high- pass filter after its waveform is processed desirably through the mutual intervention suppressing circuit, a mechanical vibration and a vibration by the mutual intervention suppressing signal becomes reversed polarity. Thus, the vibration of a head is reduced to about 1/10 lor below and the read-write operation is operated normally.
