Title: Inspection method for aperture mask
Inventor: MIYAJI YASUYOSHI
IPC: H01J9/14
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To improve productivity and prevent the improvement investigation time with respect to defective blackening from being excessively taken by providing a predicting process for observing the color of the surface of an aperture mask after a heating process and for predicting the occurrence or the non-occurrence of blackening irregularities and/or the size of the thickness of a blackened film from the observed result prior to a blackening process. SOLUTION: When an aperture mask is heated in the air environment in a heating process, an oxide film is formed on the surface of the aperture mask, and the surface of the aperture mask is normally purple red in color. When the thickness of the oxide film formed on the surface of the aperture mask is small as a whole, the surface of the aperture mask is brown. When the thickness of the oxide film is large as a whole, the surface of the aperture mask is blue. The presence or the absence of the possibility of occurrence for defective blackening, such as blackening irregularities or the improper thickness of the blackened film, can be predicted prior to a blackening process by providing a predicting process.

Title: Photometric device for camera
Inventor: MAEDA HIROSUKE
IPC: G03B7/099
Filed: 1990-09-29
Abstract: PURPOSE:To measure light over a wide range like artificial panoramic image pickup operation with simple constitution by connecting two photoconductive elements for visible light electrically in series and controlling exposure according to the sum of the resistance values of the respective photoconductive elements varying with the quantity of incident light. CONSTITUTION:Subject light beams from photometric areas which are horizontally different in position in a photographic area are made incident on the respective photoconductive elements 26a and 26b through two photodetection lenses 29a and 29b. At this time, the photoconductive elements 26a and 26b decrease in resistance value when the quantity of photodetection is large or increase when small. The photoconductive elements 26a and 26b are connected in series, so a current based upon the sum of the respective resistance values flows through a circuit. For the purpose, the circuit is so constituted that a shutter speed is fast when the photometric areas are bright and a large current flows and slow when the photometric areas are dark and a small current flows. Consequently, proper exposure is performed with the simple constitution.

Title: Power circuit for induction-heated cooking utensil
Inventor: YUASA YASUHIRO
IPC: H05B6/12
Filed: 1987-10-16
Abstract: PURPOSE:To delay the microcomputer power section output voltage reduction by preventing the reverse current to the input side from the output side of the microcomputer power section when the input power source is momentarily stopped. CONSTITUTION:A reverse current blocking means 12 such as a diode is inserted in series between the output side of the three-terminal constant voltage regulator 4 of the control circuit main power section 1 of an equipment and the three- terminal regulator input side of a microcomputer power section 6 so that the regulator input side of a microcomputer power section 6 becomes the current direction. If the regulator output side voltage of the control circuit main power section quickly drops when the input power source of the equipment is momentarily stopped, the reverse current to the input side from the regulator output side of the microcomputer main power section can be cut off. The microcomputer power section output voltage drop can be thereby delayed, and the automatic reset activation time of the microcomputer can satisfy the preset hold time of the equipment.

Abstract: PURPOSE:To prevent occurrence of clog with splash by furnishing a cap at the tip of a tool body in such a way as enclosing the discharge hole while the opening of the cap is directed to the base end in the axial direction, putting the inside space of this cap in communication with a splash exhaust groove, and thereby promoting smooth exhaust of the splash even in case the prepara tory hole to undergo the intended processing is long. CONSTITUTION:Machining oil L spouted out of a discharge hole 9 via an oil hole 8 in a tool body 1 from the machine tool side when the machining process is executed, is once supplied to the space C in a cap 11, and a great major portion of the supplied oil inverts its flowing direction and is spouted from an opening at the base end of the cap 11 toward the base end in the axial O-direction. Because this opening on the base end side is leading to splash exhaust grooves 6 in cutting edge chips 3, the machining oil L supplied to the tool body 1, as a result, flows into the exhaust grooves 6 from the foremost part so that a flow directed from the foremost in the axial O-direction to the base end is generated in these grooves 6. Accordingly the splash in the grooves 6 can be exhausted smoothly owing to the flow of machining oil L.
