Title: Container information detection apparatus and ink-jet print apparatus
Inventor: YAMAGUCHI TADAOKI
IPC: B41J2/175
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To detect whether or not an ink cartridge is set to an ink-jet printer and the amount of remaining ink in a simple constitution with high reliability. SOLUTION: The apparatus is provided with a content detection part 5 and a container detection part 6. The content detection part 5 is set to a container (ink cartridge) 2 to let a light projected from a light-emitting part 7 reach a photodetecting part 8 in accordance with the amount of ink stored and remaining in the container and the presence/absence of the container. The content detection part 5 is formed of material having light permeability and an index of refraction nearly equal to that of ink. The container detection part 6 is substantially in the same shape as the content detection part 5, whose surface to be irradiated with the light is mirror-finished. When the container is loaded, the light projected from the light-emitting part 7 is reflected at the container detection part to reach the photodetecting part 8.  On the other hand, when the container is not loaded, the light from the light-emitting part 7 runs straight and never reaches the photodetecting part 8. Accordingly the presence/absence of the container can be detected surely. Moreover, the presence/absence of the container can be detected by a detector used for detecting the amount of remaining liquid.

Title: Thin film deposition system
Inventor: MITSUI AKIRA
IPC: H01L21/205
Filed: 1990-02-15
Abstract: PURPOSE:To reduce deposited amounts of reaction by-products with the maximum increase in metal flange inside wall temperature during film deposition by providing a cooling water pipe to cool a metal flange with a remote- controllable valve. CONSTITUTION:A cooling water pipe to cool a metal flange is provided with a remote-controllable valve, where the front door closes. In a vacuum state, the temperature of front flange A1 does not increase to such a degree as to melt down an O-ring 5 even if cooling water is not flowed. Therefore, in case the reaction chamber is in a vacuum state, a program to close cooling water valves is incorporated into the sequence. This process can increase the temperature of the front flange A1 inside wall during film deposition to the utmost, thereby reducing deposited amounts of reaction by-products.

IPC: G03B17/00
Filed: 1988-02-18
Abstract: PURPOSE:To allow stable sequence operations by winding a film, charging a shutter and driving a mirror by using exclusive motors, detecting motor rotating speed and discriminating whether the motors are simultaneously driven or sequentially driven. CONSTITUTION:When an exposure operation is finished, a CPU 33 rotates the motor 1 once, and a movable reflecting mirror descends, and the shutter starts charging. At the same time, the CPU 33 detects the rotating speed of the motor 1, namely, the descending speed of the mirror, by a mirror speed detecting switch SW3. When the rotating speed of the motor 1 is slower than the specific value, the rotation is continued, and the shutter is continuously charged, and when the charging is completed, conduction patterns 8a and 8b become adjacent to each other, and the motor 1 is stopped. When a pulse signal generated by the conduction/nonconduction change of the conduction patterns 30a and 30b becomes the equivalent number to the one frame of the film, the motor 20 stops, and the film winding is completed.

Title: Magnetic disk device
Inventor: HASHIMOTO YASUICHI
IPC: G11B27/10
Filed: 1981-03-13
Abstract: PURPOSE:To improve a processing speed during access by eliminating the need for substitute processing by a disk controller by inhibiting a sector pulse output which corresponds to a defective sector by a specific means. CONSTITUTION:An ROM12 uses a track address held in a register 11 as a readout address to output a sector signal, leading a defective sector by one, from the corresponding address. A counter 15 is initialized by an index pulse IP and generates an increment output by a sector pulse SP, and its contents are compared with the output of the ROM12 by a comparator 16, thereby outputting an effective inhibition signal from the comparator 16 when coincidence between the both is detected. Consequently, an AND gate 18 is closed to inhibit the (S)th sector pulse SP from being transferred to a disk controller, so that a controller accesses a magnetic disk device by automatically jumping over the defective sector while disregarding the presence of the defective sector.

Abstract: PROBLEM TO BE SOLVED: To make sound press-contact possible by forming press-contacting ends on the surface of one side edge section of an insulating film and, at the same time, forming slots which are opened between each press-contacting end in the edge section of the film. SOLUTION: Conductive leads 3 which form a contact probe 1 are arranged in parallel with each other at short pitches on the surface of an insulating film 2 in such a manner that the leads 3 are tightly adhered to the surface. A press-contacting end 7 for the terminal of electronic parts, etc., and a connecting end 8 for an inspection device, etc., are respectively formed at both ends of each lead 3. While the press-contacting ends 7 of the leads 3 are arranged in a row in one side edge section of the film 7 by arranging the ends 7 along one side edge of the film 2, slots 9 which are opened between each press-contacting end 78 are formed in one side edge section of the film 2. Therefore, the press-contacting ends 7 are restricted and arranged in a row and the film 2 is divided into the press-contacting ends 7 and a comb-shaped insulating film piece.  The degree of flexibility freedom of the film piece can be secured, because the film piece can be bent independently in the vertical direction.
