IPC: H01L21/306
Filed: 1981-06-01
Abstract: PURPOSE:To avoid discontinuity of an upper electride and improve the yield and reliability by providing inclinations to upper edges of a lower pattern which crosses with the upper electrode. CONSTITUTION:A photoresist pattern 13 is formed on a film 12 adhered on an Si substrate 11 and the film 12 is etched off to about a half of its thickness by isotropic etching using the photoresist pattern 13 as a mask. At this time, the etching profile is are shape and eaveses 14 which have the length nearly equal to the etching depth are formed to the photoresist pattern 13. Then, if the remained film 12 is etched off by anisotropic etching, the pattern width A of the formed film pattern 12' is nearly the same as the width B of the resist pattern 13.

Title: Inner box of cooking machine
Inventor: ENAMI TOSHIAKI
IPC: F24C15/08
Filed: 1983-05-13
Abstract: PURPOSE:To eliminate leakage of electric wave and obtain excellent appearance by a method wherein the area of outer surface-outer surface contacting section of two sheets of coated steel, being connected and contacted by means of curling work, is designed so as to be larger than 1/2 of the total contact area of contacting section of two sheets of coated steel. CONSTITUTION:The tip end section of a ceiling plate 9 is formed so as to be the connecting section of curling work, folded in double. Accordingly, the area of the outer surface-outer surface contacting section, shown by marks X, of a front plate 5 and the ceiling plate 9 is more than 1/2 of the total area of the contacting section of the front plate 5 and the ceiling plate 9. According to this method, the area of conducting section is more than 1/2 of the area of total contact area and, accordingly, the leakage of electric wave due to the burn-out of coat may be reduced remarkably. On the other hand, the tip end of the ceiling plate 9 is folded in double into the inside of the connecting section of the front plate 5, therefore, the coat 5a of the front plate 5 is bent with a larger radius of curvature. Accordingly, the coat 5a of the front plate 5 will never be separated at the bent section.

IPC: G01B11/00
Filed: 1995-03-15
Abstract: PURPOSE: To improve response speed of a drive level control in the case of irradiating a substance of high reflectance. CONSTITUTION: A semiconductor laser 2 is driven by a semiconductor laser drive circuit 1. A light receive signal is received by PSD(a position sensitive device) 6, I/V converted, and added by an adder. The added output is sampled so as to input into a charging circuit 21. When the input signal is changed in the positive direction, the charging circuit 21 which rapidly charges a capacitor rapidly responds to the change in the output of an S/H circuit 10 in the positive direction so as to input it in a differential amplification circuit 22. The response speed of the driven level control signal can be thus improved, when a high reflectance substance is rapidly scanned.

Title: Overheating preventive device for data output system
Inventor: YAMASHITA JUN
IPC: G06K15/12
Filed: 1988-04-08
Abstract: PURPOSE:To detect the temperature of a head accurately and with no time delay without using a temperature sensor by detecting the electric power consumed by at least one of the head and a power supply, and estimating the temperature of at least one of the head and the power supply on the basis of the power consumption. CONSTITUTION:A current-detecting means 23 outputs a voltage signal according to a supply current, and an electric charge according to the voltage signal is accumulated into a capacitor C1 through a resistor R1. The accumulation of the charge corresponds to heat accumulation in sn LED array head 3. When the voltage signal is not outputted from the detecting means 23, the charge accumulated in the capacitor C1 is consumed by the resistor R1. The consumption corresponds to release of heat from the head 3. Where a reference voltage Vref supplied to a plus (+) input terminal of a voltage comparator 24 is preliminarily set to an appropriate value, it is possible to turn ON a READY signal when the temperature of the head 3 is not higher than a predetermined temperature and to turn OFF the READY signal when the head temperature is above the predetermined temperature. With the READY signal turned OFF, supply of an output data signal from a host computer is stopped.

Title: Detection of scanning distortion
Inventor: INOTA MASAHIRO
IPC: G01B11/00
Filed: 1981-06-03
Abstract: PURPOSE:To make the detection of the quantity of scanning distortion that changes momentarily in a real time during scanning period by converting the two-dimensional movement of a light beam to one-dimensional movement by the use of a one-dimensional condensing optical system. CONSTITUTION:The light beam of a laser light source 1 is focused via a lens 2 and a mirror 3 to the reflecting mirror surface of a galvanometer 4, and the focal point is set on the centerline of the oscillation of the reflecting mirror. The deflection point of this light is so disposed as to parallel with the plane having the condensing characteristics of a one-dimensional elliptical mirror 5. A one-dimensional sensor array 6 is disposed at the other focal position of the scanning beam by locating the array direction perpendicularly to the scanning plane. Then, the light beam moves only one dimensionally in the array direction of the array 6, and since this on-dimensional movement occurs in the inclination errors of the galvanometer 4, it is detected as the deviation information of the position by the array 6, whereby the change in the quantity of scanning distortion with respect to the optical path length of the light is detected in a real time.

IPC: C02F1/66
Filed: 1982-05-20
Abstract: PURPOSE:To contrive to hold a pH value of water flowing out through a drain pipe in a neutral range, while miniaturizing a main body, by constituting the titled apparatus in a manner such that basic substance is provided at the inlet side of the main body for the inflow of acidic dew-condensed water and that an ion-exchange body is provided at the outlet side. CONSTITUTION:The main body 1 of the apparatus has inlet and outlet openings 2, 3 at its upper and side parts, respectively, and the tubular body of a neutralizer 4 for basic substance is provided in a treating tank 5 at the side of the opening 2 inside the main body 1 under a condition floating above the bottom. In addition, weakly basic ion- exchange resin 6 is provided in a treating tank 7 at the side of the opening 3 inside the main body 1. The tanks 5, 7 are partitioned from each other by partition plates 8, 9. When acidic dew-condensed water is let flow into this treating apparatus through the opening 2 at a proper flow speed, it is neutralized with the neutralizer 4 and the resin 6 and then discharged through the opening 3. Hereon, even if an amount of acidic dew- condensed water formed from combustion gas is changed, the surface area of the neutralizer 4 coming in contact with it is held approximately constant at any times. Consequently, the dew-condensed water can be sufficiently neutralized by the resin 6 without deteriorating its neutralizing power, even if its flow speed is changed.
