Title: Manufacture of oxide magnetic thin film
Inventor: TAGAMI MASAMICHI
IPC: H01F41/18
Filed: 1979-06-12
Abstract: PURPOSE: To manufacture a magnetic thin film for high density recording on a substrate with high efficiency in a high yield by using Fe 3 O 4  or additive-contg. Fe 3 O 4  as a target and carrying out sputtering in an atmosphere of a neutral gas or a neutral gas and an oxidizing gas.  
     CONSTITUTION: Fe 3 O 4  or Fe 3 O 4  contg. an additive such as Co is used as a target, and while applying a pressure sputtering is carried out with a sputtering apparatus in a neutral gas or an oxygen-contg. oxidizing gas to form a ferromagnetic iron oxide thin film on a substrate. As the neutral gas and the oxidizing gas for the sputtering atmosphere Ar and O 2  are generally used, respectively. Both the gases may be mixed and used. This thin film can be converted into a ferromagnetic iron oxide thin film based on more perfect γ-Fe 2 O 3  by heat treatment in an oxidizing gas.

Title: Ink jet recorder of speed control and bias type
Inventor: JINNAI KOUICHIROU
IPC: B41J2/075
Filed: 1978-06-21
Abstract: PURPOSE: To provide an ink jet recorder, by which a character is divided into picture elements, each speed of ink drops is controlled according to the positional informations of respective picture elements, then the ink drops are charged, and the charged ink drops are biased under a certain voltage to reproduce the picture character on a piece of recording paper.  
     CONSTITUTION: Ink in an ink jet head 3 is ejected by pressure from an ink feeding pump, is separated into charged ink drops at charging electrodes 4 due to the oscillation of an electric distortion oscillator 2, and the charged ink drops are biased by bias electrodes 8 to be printed on a piece of recording paper 10 as dots. Thus in this case, the degree of bias of an ink drop can be varied according to the ejected speed of the ink drop, and therefore desired degree of bias of an ink drop can be obtained by controlling the ejected speed of the ink drop. The present recorder has advantages, for example, that since ink drops are charged to the same level, applied voltage to the charging electrodes may be constant, and only when printing is required, ink will be ejected by the oscillation of the electric distortion oscillator.

Title: Displacement detector
Inventor: ARIMURA YOSHIAKI
IPC: G01D5/30
Filed: 1986-04-02
Abstract: PURPOSE:To detect the displacement position of an article to be measured with good accuracy, by selecting a sensor outputting a max. value signal from sensors outputting detection signals corresponding to the position of the article to be measured and outputting the code signal inherent to the selected sensor. CONSTITUTION:For example, in the case of a rotary encoder, the light emitted from a light emitting diode 6 is incident on an optical fiber 10 and subsequently incident to a photodiode 7-1. Even when the output light emitted from the optical fiber 10 is not condensed to one photodiode 7 but irradiates two or more photodiodes 7, the photodiode 7 max. in light receiving quantity is selected and the code signal inherent to the selected photodiode 7 is outputted. Because the interval between the photodiodes provided in a row can be made narrower than the width of the light emitted from the optical fiber 10, the photodiodes 7 can be arranged in a row in a state compressed at high density and quantity of rotation can be detected with high accuracy.

Title: Ignition timing controller for turbosupercharged engine
Inventor: ITOU YOSHIYASU
IPC: F02D23/00
Filed: 1983-04-28
Abstract: PURPOSE:To make idle-up control attainable while checking the wastage of fuel consumption, by controlling the ignition timing to advance as far as the specified angle when a fact that an idling speed is in a state of being upped is so judged in time of idling. CONSTITUTION:In time of engine driving, first of all, that whether a throttle valve is in a fully closed state by a signal out of a throttle sensor 6 or not is judged by a computer 1. When it is judged as ''YES'', the ignition timing is calculated so as to be suitable for a state of idling. That is to say, on the basis of an engine speed obtainable from the output of a turning engine sensor 7, an ignition timing map inside a ROM is seached whereby the ignition timing is found. Next, judging from a control signal and the like in relation to an idle-up speed control valve 4, a fact on whether idle-up control is going on or not is judged, and when a ''YES'' judgment is the case, ignition timing in time of idling is controlled to advance as far as the specified angle and thereby an igniter 2 is controlled, thus idle-up control takes place while checking the wastage of fuel consumption.
