Title: Insulator for electrical dust precipitator
Inventor: MIMURA YUUJIROU
IPC: B03C3/70
Filed: 1983-02-04
Abstract: PURPOSE:To obtain a good insulating condition and to maintain a function as an insulator by providing an air chamber in the insulator and constituting the insulator so as to have the width of an evacuating slit larger than an electrical insulation spacing. CONSTITUTION:A hollow air chamber 2 is provided in an insulator body 1, and a hole for feeding clean air from the outside into the chamber 2 and an evacuating hole 5 for evacuating the air from the chamber 2 to the outside of the insulator are provided. The shape in the insulator surface part of the hole 5 is made into a slit shape 6 and is made larger than the space of the slit so that the wall surface of the chamber 2 serves as an insulating surface.

Title: Toner concentration controller
Inventor: ISHIDA KAZUYA
IPC: G03G15/08
Filed: 1987-01-28
Abstract: PURPOSE:To obtain sufficient image density even at the time of low humidity by driving a toner replenishing mechanism independently of control based upon a toner density control means when the image density detected by an image density detecting sensor is lower than a prescribed density value. CONSTITUTION:When the image density is more than prescribed density, toner replenishment to the developer in a developing device is controlled by a detecting signal from a sensor for detecting the toner concentration in a ATDC controlling developer by using the toner replenishing mechanism 47, a toner concentration detecting sensor 46 and a toner concentration control means to fix the toner concentaration. When the image density is thinner than the prescribed density, the toner mechanism 47 is forcedly driven independently of ATDC control, the toner concentration is increased and the image density is restored to a level more than the prescribed density. Thus, the image density can be prevented from being lowered even at the time of low humidity.

Filed: 1978-02-21
Abstract: PURPOSE:To operate the electric contacts with the operating protrusion part provided integrally with a center frame by providing the center frame composed of synthetic resins having elasticity between the watch case, back cover and movement and making use of its elasticity. CONSTITUTION:A center frame 4 composed of synthetic resins having elasticity is disposed between the inside circumference of a watch case 1 and movement 5.

Filed: 1980-02-18
Abstract: PURPOSE:To prevent destruction of an IC by detecting the IC test pattern which is prohibited from being applied for a long period of time and changing it over after a certain period of time. CONSTITUTION:In the case of a specific pattern, by which contention of outputs arises in the tri-state or the like and a long-time application of which may result in destruction of an IC, an element destruction indicating flag bit 17 is stored correspondingly to a pattern data 16 in a pattern storing memory 15. When said specific pattern is accessed by the count of an address counter 14; even if abnormality is detected, the input of an terminal 11 is 0 and the pattern is fixed; the output of the bit 17 enters an OR element 12 to actuate a starting pulse generator 13 to advance the address counter 14. Thereby, there is no possibility of a long-time application of the pattern which may destroy the IC19 being tested.

Title: Printing method by charging deflection type ink-jet printer
Inventor: EBI YUTAKA
IPC: G06K15/10
Filed: 1980-02-18
Abstract: PURPOSE: To improve printing quality in a charging deflection type ink-jet printer by charging ink drops in a specified order.  
     CONSTITUTION: Ink drops jetted from an ink-jet head are charged and deflected by deflecting electrodes to print a recording paper. In this case, when the maximum number of columns to charge ink drops is M, each column is divided into the number K of lines which is obtained by dividing the maximum number M of charging columns by a natural number N (N≥3), and charging is performed in the order of lines. Moreover, on the first line, charging is performed so as to start from an arbitrary column (≤K) and skip over K; on the second line, from an intermediate column L and skip over K; on the third column, from an intermediate column P and skip over K and so on. Thereby, the influences of air resistance and coulomb force exerted by a preceding charged ink drop on a succeeding charged ink drop can be minimized, so that ink drops are allowed to fly substantially independently of each other.

Abstract: PURPOSE:To prevent effectively the occurrence of channel current, to reduce leakage current between a gate and a cathode of GTO and thereby to prevent the deterioration of a gate turn-off characteristic, by curbing the inversion of a digged-in portion of a PB layer to an N<-> layer which is caused by the re-increase of the impurity concentration of the PB layer, lowered with digging-in, due to the diffusion of Ga. CONSTITUTION:After an NE layer 2 is diffused selectively in a PB layer 1 in the same way as usual first, mesa etching is applied to form mesa junction, and then an insulating film is formed as a mesa passivation film in the portion of the mesa junction. After Ga is deposited on this insulating film subsequently, Ga is driven in for a prescribed time, and lastly a PSC film is deposited. For instance, mesa passivation oxidation is executed for one hour, at the temperature of 1,200 deg.C and in wet oxygen (wet O2), Ga is deposited thereafter for 15min, and then Ga is driven in for 30min in wet O2. Thereby the inversion of digged-in portion of the Pb layer 1 due to ionization, i.e. the inversion thereof to an N<-> layer, is curbed very much.
