Title: Manufacture of semiconductor integrated circuit device
Inventor: NAITO SHIGEYUKI
IPC: B23K26/38
Filed: 1987-05-27
Abstract: PURPOSE:To cut a semiconductor wafer into a plurality of chips without generating microcracks, by cutting the semiconductor wafer into a plurality of chips by using laser. CONSTITUTION:A dicing region 2 is cut down up to a specified depth by a dicing saw 4. In this case, the dicing region 2 is not compeletely cut off, but a cutting residue 5A is formed, whose thickness is, e.g., about 20 mum. In order to generate no cracks on the bottom, the side surface, etc., of the groove 5, the wafer is subjected to cutting while water is sprinkled. The spot diameter of a laser 6 is made sufficiently small, in order to irradiate the bottom of the groove 5 formed by the dicing saw 4. The spot diameter is made smaller than the thickness of the dicing saw 4. The cutting residue 5A is melted and cut by radiating the laser 6. Thereby, mechanical impulse is not applied to the cutting residue, so that microcracks do hot generate.

Title: Cr differentiation timer circuit
Inventor: MATSUDA MASANORI
IPC: H03K17/28
Filed: 1985-06-13
Abstract: PURPOSE:To attain accurate timer operation by connecting a series circuit composing of the 2nd resistor and a capacitor in parallel across the 1st resistor of a circuit connected to a power supply and connecting a midpoint between the 2nd resistor and the capacitor to a base of a transistor (TR). CONSTITUTION:The series circuit composing of the resistor R2 and the capacitor C is connected in parallel across the resistor R1 to which a switch SW is connected in series and the midpoint between the resistor R2 and the capacitor C is connected to the base of the TR. When a silicon TR is employed, a silicon diode is used for the diode D and the when a germanium TR is employed, a germanium diode is used. Thus, the forward voltage drop VB, VD of the p-n junction of the TR and the diode D are nearly equal to each other. Since the forward voltage drop is that for the same kind of the p-n junction, the temperature characteristic is similar at an optional temperature. Then the operating delay time td of the timer depends on a product CR2 and the temperature change and a power supply voltage VCC are independent of the time.

Title: Exposure control circuit for camera
Inventor: NAKAJIMA YUKIO
IPC: G03B7/083
Filed: 1987-05-26
Abstract: PURPOSE:To make an exposing time accurate without receiving the effect in deviation of integration starting point and offset voltage, etc., of an operational amplifier and a comparator by detecting the increasing portion of the integral value of a photocurrent. CONSTITUTION:When an integration starting signal is received from a shutter button, etc., a switch 4 is turned off. At this time, a switch 5 is turned on and a switch 10 is turned off, and then a capacitor 3 begins to be charged with the photocurrent from a photodiode 1 and a current from a current source 6. When the charged voltage is integrated in the operational amplifier 2 and an output Vout reaches a decision voltage Vc through the comparator 7, a control circuit 12 precedes a front curtain and at the same time the switch 5 is tuned off and then switch 10 is turned on. From this time the capacitor 3 is charged only with the photocurrent from the diode 1. And when the Vout reaches the new decision voltage Vc raised by a current source 11, a rear curtain precedes. Therefore, the accurate control of exposure can be possible without receiving the effect of the offset voltage.

Inventor: INABA ZENJI
IPC: B29C45/66
Filed: 1989-05-24
Abstract: PURPOSE:To automatically perform the controlling of mold thickness and consequently perform mold changing operation efficiently by a method wherein the shifting amount and direction of the position of a rear platen in calculated by a control device by inputting the thickness of a new mold, the thickness of a mold to be changed and the shifting amount, which corresponds to mold clamping force, of the rear platen in order to position the rear platen. CONSTITUTION:When a mold 16 having the thickness (y) is intended to be mounted, the thicknss (y) of the mold 16 is set in a control device for the controlling of mold thickness. At this time, a rear platen 2 is shifted by the amount P=(x-y-A+delta). Concretely, the amount P is obtained by subtracting the thickness (y) of the mold after mold change 16 and the elongation A of tie bars, which is given to the mold before mold change 8 and corresponds to the mold clamping force, from the thickness (x) of the mold before mold change 8 and adding offset amount (delta). When the shifting amount P is positive, the rear platen 2 is advanced. When the shifting amount P is negative, the rear platen 2 is retreated. When the rear platen 2 is shifted by the shifting amount P, a movable platen 4 is also shifted by the same amount or the coordinate position of the movable platen 4 turns to be Q-Z+x-y-A+delta. By advancing the movable platen by Z, the movable platen is positioned and the controlling of mold thickness is finished.

Filed: 1981-08-19
Abstract: PURPOSE:To enable to change the range of setting flow rate with ease, by providing by-pass passages having variable by-pass ports independent of a main valve port designed to be variable in a conventional manner. CONSTITUTION:In case of controlling a flow rate by use of the value of constant flow rate determined by a main valve port 4, all of by-pass passages 13 are closed by use of a blind control plate 17 formed with no holes. In this state, by- pass valve ports 12 are all rendered inoperative, so that constant-flow control is made by the main valve port 4. On the other hand, in case of increasing the range of constant-flow rate, the flow rate can be changed with ease by replacing the control plate 17 by one having one or more holes capable of communicating such a number of by-pass passages 13 as to correspond to the increment of flow rate.

Title: Method of producing shield beam type lamp
Inventor: FUKUYAMA KATSUHIRO
IPC: H01K7/02
Filed: 1977-10-27
Abstract: PURPOSE: To provide a high quality shield beam type lamp excellent in appearance through an evaporation of a metal with a shield member provided close to the inner surface of the opening section of a reflecting mirror section.  
     CONSTITUTION: With the actuation of a vacuum pump, air in an evaporation head 1 is discharged through a conduit 8 communicated to the pump to form a vacuum therein. When the degree of vacuum reaches 10 4  to 10 5  torr, a coil heater 2 is energized through terminals 7 to evaporate an aluminium foil 3 over the inner surface of a reflecting mirror section 5. In this process, since the periphery of the section 5 is covered with a shield plate 6, the periphery is free from coating of aluminium. Accordingly, even when the periphery is heated during a tight welding of the connection between the opening section of the section 5 and the lens section of the lamp by means of an engaging lever or the like, neither dispersion nor color change of the evaporated film takes place due to lack of aluminium in the area being heated.
