Title: Micro wave oven
Inventor: TAKADA YOSHIYUKI
IPC: H05B6/64
Filed: 1988-06-17
Abstract: PURPOSE:To obtain a micro wave oven of simple structure with a good cooling ability at a low cost by making the structure such that, in a sectional form of a fin-like flange of an air guide, thicknesses of the edge and the bottom of the flange are of the same or the edge is thicker. CONSTITUTION:In structure, a flange portion 3a of an air guide 3 is formed by a resin to provide resiliency, making the edge and the bottom of a flange fin-like in the same thinness in sectional form, as well as having a slit 36 formed on the corner of the flange 3a. The periphery of the flange 3a of the air guide 3 being highly flexible, with good linearity, and with smooth flow of a resin during formation, it adheres to the external wall 26 of a heating chamber even if there is a small degree of roughness on the surface of the external wall 2b of the heating chamber 2. A portion of the wind blown out of a fan 6 passes through a cooling wind passage 1-a of a magnetron 1, entering an air guide 3 and changing direction, is exhausted from an inlet pore 2-a of the heating chamber into the heating chamber 2. Since adhesion between the external wall 2-b of the heating chamber and the flange 3-a of the air guide is good, no bad effect is produced on temperature rise of the other electric parts.

Title: Video signal processor
Inventor: KAWAHATA HITOSHI
IPC: H04N9/87
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To reduce a circuit scale for performing a noise reduction(NR) processing and a Y/C separation processing and to improve accuracy at the time of an NR operation. SOLUTION: A switch 23c selects a terminal 23b when the switch 1c selects base band video signals as input and the switch 23c selects the terminal 23a when the switch 1c selects composite video signals as the input. In a BPF, non-correlated components are extracted from the output of an A/D converter and line memories 5 and 7 and optimum non-correlated components are selected and supplied through a variable circuit and a nonlinear filter to a subtractor 27. An inter-frame signal processing circuit performs an inter-frame NR processing at the time of the NR operation and an inter-frame Y/C separation processing at the time of a Y/C separation operation. The subtractor 25 subtracts the output of the variable circuit 17 from NR processed video signals and attains NRed video signals.  The subtractor 27 subtracts the non-correlated signals of the nonlinear filter 19 from the composite video signals and Y/C separated video signals are attained in a mixer 29.

Filed: 1980-10-27
Abstract: PURPOSE:To prevent backward flowing and unsmooth flowing of a copy original, disturbance of stack order, etc., by providing a back flow prevention member for inhibiting its back flow without hindering unloading flow of the original, near its outlet.

Title: Clocking system for operating state of taxi
Inventor: MIYASHITA YUKIHIRO
IPC: G07C5/00
Filed: 1988-06-17
Abstract: PURPOSE:To attain efficient clocking by changing a time interval for the clocking operation of an empty taxi in accordance with the length of continuous time of the same operating state. CONSTITUTION:A data signal formed by a data signal generating circuit 7 is transmitted to a base station 4 by a radio transmitter/receiver 3 on a taxi 2. The circuit 7 includes a timer circuit 8 and the circuit 7 counts up the continuous time from the start of the empty state in response to the clocking operation of the circuit 8. The clocking operation is executed every 1st time T1 within a previously determined fixed time T from the time t1 emptying the taxi, and after the passage of T, executed every 2nd time T2 and the continuous time data are updated every clocking operation and sent to the station 4 as the signal D. In the station D, the signal D is processed by a processor 6 to grasp the position of each taxi and the empty time of the taxi. In accordance with a request for meeting a taxi, an empty taxi 2 having a long empty time is commanded to meet a customer. Since the clocking operation is executed in accordance with the length of the empty state continuing time, accurate and efficient clocking can be attained.

IPC: G02B7/04
Filed: 1989-06-13
Abstract: PURPOSE:To prevent impact from being frequently or successively given to a zoom lens by detecting that the impact those strength is to a certain extent or more is given to the zoom lens from the outside and moving the zoom lens to a proper protective position. CONSTITUTION:When the impact such as pressing force, etc., is given to the zoom lens 5 from the outside, it is detected by an impact detection means 1 and a control means 4 supplies a moving and advancing signal to a zoom lens driving means 3 by receiving an impact detection signal from the means 1. Therefore, the zoom lens 5 moves from a proper position toward the protective position. When the zoom lens 5 moves to reach the protective position, a protective position detection means 2 is actuated and the control means 4 supplies a stop signal to the zoom lens driving means 3 by receiving a protective position signal from the means 2. Thus, the impact is prevented from being successively given to the zoom lens 5 from the outside.

Title: Guide rail of elevator in unit-type building
Inventor: TOKUNARI HIROHISA
IPC: B66B7/00
Filed: 1995-06-19
Abstract: PURPOSE: To prevent taking comfort of an elevator from being deteriorated even if facing ends of upper and lower guide rails are deviated in such a direction as to be approached to each other, by the combination precision of upper and lower building units and the assembly precision of respective building unit themselves. CONSTITUTION: Since upper and lower guide rails 8 are separated from each other by the dimension T, the deviation amount is absorbed by the clearance of the dimension T even if respective guide rails 8 are deviated in such a direction as to be approached to each other. Therefore, facing ends 8C are not struck against each other, the distortion of respective guide rails 8, to be generated caused by striking is eliminated, and the slide movement of a guide part 4A can be smoothly performed.

Title: Inspection mark
Inventor: KOMAI MASATSUGU
IPC: G03F1/44
Filed: 1988-06-20
Abstract: PURPOSE:To easily inspect an appropriate focal point by forming a triangular mark for inspecting an appropriate focal point on a photomask for exposing a fine pattern. CONSTITUTION:A triangular mark is formed on the photomask. In two edge parts 2 and 3 making 45 deg. angles of the inspecting mark 1, a line width varying rate due to a change in the focal point at the time of exposure fluctuates greatly, and in appropriate focusing, line width becomes the smallest, whereas in out-of-focus, it becomes greater. When light enters obliquely due to defocusing, line width changes significantly to be greater, and accordingly an exposure pattern with the round edge parts is appeared. In the case of appropriate focusing, an exposure pattern with the sequare edge parts is appeared. Consequently, appropriate focusing can be confirmed at a glance.
