Patent JP-H0359628-A (JP)
Title: Camera system
Inventor: IKEMORI KEIJI
IPC: G03B19/00
Filed: 1989-07-28
Abstract: PURPOSE:To reduce the overall size of the camera system while providing the function of a TTL type single-lens reflex camera by dividing a photographic distance range into a long-distance range and a short-distance range and specifying observation systems corresponding to these distance ranges. CONSTITUTION:The photographic distance range of a photography system 1 which has a focus part is divided into the two distance ranges, i.e. a 1st distance range and a 2nd distance range. Then, luminous flux which is passed through the photography system 1 is converged through a rotatable mirror M1 in the distance range wherein the space between the photography system 1 and an image plane is wide to form an object image on a specific plane and the object image is observed by the ocular of an observation system A through an erect non-reverse image member. Further, luminous flux passed through an objective lens provided independently of the photography system 1 is converged by an ocular 11 in the distance range where the space between the photography system 1 and an image plane is narrow is guided to an ocular 11 to observe an object image through an observation system B102. Consequently, the overall size of the camera is reduced almost to that of a two-focus switching type small-sized camera.

Title: Deck-landing guide for helicopter and vertical take-off and landing plane
Inventor: TAMURA TETSUYA
IPC: B64D45/04
Filed: 1990-07-26
Abstract: PURPOSE:To perform deck-landing quickly and safely by installing a measuring instrument for the altitude and distance of a helicopter-VTOL plane and a device for transmitting the measured data both in a ship with a landing deck, and setting up another device, receiving the data and displaying it in a pilot, in the helicopter-VTOL plane. CONSTITUTION:A device 3, measuring the altitude and distance of a helicopter 2 or the like to be landed on a ship 1 with a landing deck and transmitting the measured data at real time, is installed therein, while a device 4 receiving data transmitted out of the ship and another device 5 displaying the data are installed as well. A pilot is steering an air frame so as to reduce a vertical motion (heaving) in his own plane with a deck of the ship as looking a position of his own plane with the deck, and then he is gradually lowering the altitude for landing as controlling it so as to make motion of this own plane accord with the heaving at a deck-landing position of the ship. Thus, the degree of dependence on skill of the pilot becomes lowered, and time required for the deck-landing is shortened, thus a range of operation of the helicopter or the like on a deck of the ship under bad weather is enlarged.

Title: Logic circuit having two input and one output
Inventor: TAEESU JIYUN
IPC: H01L27/092
Filed: 1990-07-26
Abstract: PURPOSE: To reduce the design layout area of a logic circuit by providing two inputs and one output and, at the same time, using two insulating gate FETs. CONSTITUTION: When logic '0' is impressed upon one input terminal A of a logic circuit, an N-channel MOS transistor(Tr) 32 is not conducted, but a P-channel MOS Tr 33 is conducted. As a result, the output of the logic circuit becomes logic '1' regardless of the state of the other input terminal B'. When logic '1' is impressed upon the terminal A, on the contrary, the Tr 33 is not conducted and the Tr 32 is conducted. In this case, the output terminal 35 of the circuit becomes logic '0' when the input terminal B' becomes logic '1' and logic '1' when the terminal B' becomes logic '0'. Therefore, the circuit functions as a NAND gate in which the terminal 35 becomes logic '0' only when logic '1' is impressed upon both the input terminals A and B'. Therefore, the degree of integration of a semiconductor chip an be improved by making the design layout area of a logic circuit smaller.

Title: Cmos operational amplifier
Inventor: KOIDE JIRO
IPC: H01L21/8238
Filed: 1991-08-06
Abstract: PURPOSE:To extremely reduce the power supply noise of an amplifier and, at the same time, to stabilize the operation of a digital-analog mixed integrated circuit by forming a capacitor of the first and second metallic wiring layers facing each other with an interlayer insulating film in between. CONSTITUTION:A capacitor is formed by facing the first and second metallic wiring layers 2 and 3 with an interlayer insulating film in between. When the capacitor is formed in such way, high-frequency digital noise superimposed upon a power supply voltage line is by-passed from a VDD (positive voltage) to a VSS (negative voltage), because an electrostatic capacity is formed between the VDD and VSS, and the capacitor is formed to the power supply line of an amplifier. Therefore, a measure can be taken against the noise of the amplifier by the conventional two metallic layer wiring technique without changing its process.

Abstract: PURPOSE:To carry out accurately and surely transcribing an uneven pattern and to prevent a product from warp, by heating the cavity face with a high temp. heating medium when a molten polymer resin is injected and filled into a cavity and cooling the cavity face with a low temp. heating medium when cooling and taking-out. CONSTITUTION:At a specific time before a time when a molten polymer resin is injected and filled into a cavity 3, switch valves V3 and V4 are closed and switch valves V1 and V2 are opened to heat the cavity face at a specific temp. in advance. As temp. decrease of the molten polymer resin is small and resin flow property becomes good by doing so, transcribing property of an uneven pattern is good and occurrences of resin orientation, optical strain, weld lines and the like can be prevented. When the molten polymer resin is fully filled into the cavity 3, the switch valves V1 and V2 are closed and the switch valves V3 and V4 are opened to cool the cavity face to a specific temp. and to accelerate hardening of the resin. As a molded disc base plate is cooled rapidly with the heating medium, no warp exists therein.
