Title: Method and device for drilling thin sheet
Inventor: HAYAKAWA JUN
IPC: B26F1/24
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To effectively drill a small diameter hole on a fine sheet with a simple device about the technical means to drill a hole from several hundred to several microns on a material. SOLUTION: A tip cut wire 1 is inserted in a tube 2 having the internal diameter made larger only by the clearance part 7 as the fluid passage than the external diameter of the wire 1, in the state of retreating the tip 1a of the wire 1 from the tip 2a of the tube 2 to the base end side and restricting the movement of axial direction of the wire 1, the fluid flow is generated in the clearance 7, next, by releasing the restricting movement of the wire 1 in the axial direction, the wire 1 is transferred with the fluid friction, the tip 1a of the wire 1 is collided to a fine sheet and the sheet is drilled. The wire 1 is made more slender, the surface area per unit mass of the wire is made larger, so the large machining force can be applied relatively.  Because the transferring force of the wire 1 is applied with the circumferential fluid friction, the buckling of the wire 1 caused on the machining reaction force can be avoided. After drilling, the wire 1 is retreated to a prescribed position with a wire retreating means 13 and the preparation of next drilling is completed.

IPC: G06T1/20
Filed: 1990-02-16
Abstract: PURPOSE:To obtain a histogram at a high speed by providing a 2PORT-DRAM and a counter. CONSTITUTION:The image data dots are serially added to a 2PORT-DRAM 1 for each scan, for example, and the 2PORT-DRAM changes the address of one of both ports as an address kept in a single scan and stores this changed address for each dot. Then the direction vertical to the scanning direction inputted when a single screen is through is pointed with the address of the other port. Therefore the dot data on the vertical direction contained in the 2PORT- DRAM 1 are added to a shift register. The dot data on the direction vertical to the scanning direction are serially outputted with addition of a shift clock. A counter 2 counts the horizontal dots in an input state and the vertical dots in an output state respectively via a selection circuit 3. Thus the horizontal and vertical histograms can be obtained at a high speed.

Title: Inspection apparatus and removing apparatus for substrate-adhering foreign matter and method and removing adhered foreign matter
Inventor: SHUDO KAZUO
IPC: G01N21/88
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To detect an adhered foreign matter by irradiating the entire surface of a substrate with parallel laser light and detecting a change in illuminance of a passing light with an illuminance meter. SOLUTION: A glass substrate 6 is fixed through suction by supporting pins 4. A laser beam 100 from which an extra light has been eliminated by a slit 3 passes a position separated such a slight distance that the beam nearly touches a lower face of the substrate 6. An illuminance meter 8 is set to the side opposite to a laser light-projecting part 1, and measures an intensity of the laser beam 100 every time the swept laser beam enters the meter. The illuminance meter 8 moves in a lateral direction by the rotation of a ball screw 9 and the therefore can obtain an illuminance signal to a move distance as a function. If a foreign matter 7 is present, the illuminance decreases because of the shadow. The foreign matter 7 can be discovered accordingly.  Moreover, a position coordinate of the foreign matter 7 can be obtained from a coordinate of the ball bearing 9 at the time when the signal is obtained.

Abstract: PURPOSE:To obtain P-ROM small both in area and contact resistance by a method wherein a semiconductor domain isolated by a thick film through selective oxidization is exposed for covering with poly-Si, and an electrode is placed on the semiconductor surface after base-emitter diffusion given in sequence. CONSTITUTION:An n<+> buried layer 2 and an n<-> epitaxial layer 3 are formed on a p<->-type Si substrate, an isolated layer 4 is formed through oxidization with an Si3N4 as a mask, and the layer 3 is exposed by eliminating an oxidized film on the portion surrounded by the layer 4. Next, the layer is covered selectively with an Si film 11 wider than the portion exposed according to CVD process. Then, B ion is implanted to form a p-base 12 in the domain 3, and p ion is further implanted to form an n<+> emitter 13. An Al wiring 14 is formed on the poly-Si film. According to this method, a contact area is taken larger than ever before between poly-Si and Al, and since it can be taken full of the emitter area, an Al-Si contact resistance dose not grow large, and thus a device with small area and contact resistance is obtainable.

Title: Turbo-molecular pump driving power unit
Inventor: CHINO HIROYUKI
IPC: F04D27/00
Filed: 1989-02-14
Abstract: PURPOSE:To secure required driving force as well as to keep off generation of heat in a motor by selecting an output voltage in an inverter output circuit automatically according to a load change at times of speed-up and rated speed. CONSTITUTION:Since an output current of an inverter output circuit 3 being fed to an a.c. motor 4 is large enough at time of speed-up, a current value being detected by a current detector 6 is larger than a reference value out of a reference circuit 8 whereby in this inverter output circuit 3, frequency and voltage both go up in accordance with control over an output voltage/ frequency control circuit 5. When a rotational speed is reached to the vicinity of rated speed, load of the a.c. motor 4 is decreased, and when the detected current value becomes smaller than the reference value, a comparator 7 outputs an output voltage signal to the output voltage/frequency control circuit 5, selecting an output voltage in the inverter output circuit 3 to the lower value. In addition, when a load change has been done at the rated speed during operation, the comparator 7 turns an output voltage selector signal to ON or OFF according to a fact that the detected current is less than the reference or more than it, thereby selecting the output voltage of the inverter output circuit 3.
