Title: Electrostatic chuck
Inventor: KUNIOKA TATSUYA
IPC: B23Q3/15
Filed: 1990-03-19
Abstract: PURPOSE:To tear any object attracted to an electrostatic chuck using a low resistance dielectric substance in a short time by furnishing a measuring means for electric field generated with residual electric charges on the surface of the chuck, and providing a means to control tearing of the attracted objects by reference to the results from measuring. CONSTITUTION:When an object attracted 1 is to be torn, a contact changeover device S1 is turned to (b) side while another S2 turned to (a) side, and reverse voltage is impressed on an electrode 2. At this time, the contact changeover device S2 is turned to the (b) side shortly after the reverse voltage is impressed, and the voltage is put afloat from the ground. The residual electric charges are determined by measuring the electric field in this floating condition, and on the basis of results from measurement a voltage controller 9 determines the optimum reverse voltage, and the voltage value of a variable voltage source for tearing 12 is set. After the setting, the contact changeover device S2 is turned again to the (a) side. Repeating this sequence from the electric field measuring to impression of the optimum reverse voltage until the electric field nullifies, should nullify the residual electric charges without being affected by the initial residual electric charge amount or the leak characteristic of the dielectric substance.

Title: Firing timing detection circuit for internal-combustion engine
Inventor: KIMURA YUTAKA
IPC: F02P17/02
Filed: 1983-04-20
Abstract: PURPOSE:To detect the firing timing accurately without delay by detecting only at the start of firing through an input detection circuit on the basis of an input signal having required level converted through a shaper circuit while detecting pulse series signals through a mono-stable multivibrator. CONSTITUTION:Every time when a voltage signal V1 concerning to the firing function is applied onto an input terminal 28, firing timing signal SO constituted with stable pulse series having constant pulse width is detected without lagging from occurrence of said signal V1. In the function of firing timing detector, the circuit 21 will function as a mono-stable multivibrator to set the referential time Ta for determining the pulse width of each pulse SOP in said firing timing signal SO. Consequently even for variation of rotation from low to high, the pulse width of said signal SO is always constant. Even if the voltage signal V1 to be provided to the input terminal 28 is a high voltage signal, it is converted through the shaping circuit 19 to the required level and never causes delay.

Title: Dry etching equipment and cassette
Inventor: MURAMATSU KIMIO
IPC: H01L21/3065
Filed: 1988-03-25
Abstract: PURPOSE:To prevent corrosion of Al on the surface of a dry-etched wafer, by depositing chlorine ions on the wafer surface by a vacuum vaporization by a method wherein sheet-like heaters are incorporated in a cassette for unloading. CONSTITUTION:In a cassette 12 for unloading to store dry-etched wafers 7, sheet-like heaters 15 are located at fixed distances. The wafers 7 are stored between the heaters 15. The heaters 15 heat the wafers 7 to a temperature so that chlorine ion corrosive material attached to the surface of the wafers 7 is vaporized. Vaporized gases are exhausted. Since the dry-etched wafers 7 are heated in the cassette 12 before being taken out of the equipment, chlorine ions on the surface of the wafers 7 is vaporized in a vacuum to be exhausted. As a result, corrosion of Al on the surface of the etched wafers 7 is prevented.

IPC: H01R12/24
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To mount a flexible printed wiring board inside a housing with a simple operation by stopping, between a slide and the housing, the slide in a position to be inclined obliquely upward relative to the housing. SOLUTION: When a slide 5 is forcibly rotated in the clockwise direction around an engaged second projection 11 from its stop position, the spherical projection 31 of a locking means 30 and a recessed part 32 formed in the bottom surface 6a of a guide groove 6 are fitted to and engaged with each other, thus the rotation of the slide 5 in the counterclockwise direction is prevented and it is positioned and locked in this position. Thus, the tip 5a of the slide 5 is raised obliquely upward so as to facilitate the insertion of a flexible printed wiring board and, since the slide 5 is positioned and locked in the inclined position by the locking means 30 when its inclined attitude is maintained, no external supports for the maintenance of this inclined attitude are necessary.
