Title: Clean room
Inventor: HIRATA JUNTA
IPC: F24F7/06
Filed: 1990-03-13
Abstract: PURPOSE:To prevent a back-flow in an air cleaner stopped when an thinned-out operation is carried out and further prevent a contamination of a downstream side surface of an air filter by a method wherein a back-flow preventing means is arranged at an air inlet port of the air cleaner of which stopping state is expected. CONSTITUTION:Since no worker is present in a cleaning work area 16 when a production is stopped, air cleaners 12a and 12d placed over a cleaning passage 21 (a passage between the devices 18) in the cleaning work area 16 are stopped. At this time, since a back-flow preventing damper 14 is closed at the stopped air cleaners 12b and 12d, a back-flow (a flow from an air filter 11 to an air inlet port 13) is prevented, a contamination at a downstream side surface of the air filter 11 is prevented. Accordingly, when the operation is started again, the clean room is not contaminated.

IPC: G01P1/08
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a vibrationproof thermometer which prevents a well from being broken due to its resonance with an exciting source such as Karman's vortex or the like, which prevents a screw part from being broken down due to metal fatigue, in which a time constant does not become large when a temperature is measured by the thermometer and whose temperature detecting accuracy can be maintained. SOLUTION: A vibrationproof thermometer is composed of a well 100, a thermocouple 30 and a junction head 40, it is attached to piping 20 which is vibrated, and it measures a temperature inside the piping 10. In the vibrationproof thermometer, the well 100 is composed of a pipe inside well 101 and a pipe outside well 102. The mass of the pipe outside well 102 is made equal to, or more than, the mass of the piping inside well 101. The moment of inertia of the piping outside well 102 regarding an arbitrary axis which is inside the well mounting face 103 of the piping 10 and which is passed through the center of the well 100 is made smaller than the moment of inertia of the piping inside well 101 regarding the axis.

Title: Ohmic electrode for semiconductor device
Inventor: KAWADA HARUO
IPC: H01L29/417
Filed: 1987-03-19
Abstract: PURPOSE:To improve the uniformity in a plane and the reproducibility of FET characteristics by forming a source or a drain ohmic electrode in a sawtooth shape. CONSTITUTION:An ohmic electrode 14 facing a gate electrode 6 is made a sawtooth shape and the directions of all sawteeth are arranged in the direction of <100>. Accordingly, the end of the ohmic electrode 14 is not affected by a piezoelectric charge due to the difference of the coefficients of thermal expansion of an insulating film such as SiO2 or Si3N4 for passivation or interlayer insulation and GaAs crystal since the piezoelectric charge is not generated in the direction perpendicular to an axis <100>. This improves the uniformity in a plane and the reproducibility of ohmic resistance and the uniformity in a plane and the reproducibility of FET characteristics are improved.

Title: Picture monitor transmitter
Inventor: FUJII HISATAKA
IPC: H04N7/18
Filed: 1989-03-15
Abstract: PURPOSE:To attain quick monitor picture by sending to a receiver side only part newly entering a still picture attended with the movement of an image pickup means and synthesizing the part onto the picture having already been and received and displaying the synthesized picture. CONSTITUTION:After a sent picture data is decoded on a receiver side, a preceding pattern preserved in a receiver side pattern memory having already been displayed on a display device 11 is moved to the right or the left by X dots and the sent picture data is displayed in the blanked part to display the picture of the camera 3 after movement. When the picture is moved to the left and right at a small interval, since the picture near the center is not updated, all the picture is sent at each prescribed time. Thus, the movement is smaller than the entire picture element except a large camera movement. Then the picture data quantity sent after the end of the movement of the camera is small, the time required for compression, transmission and decoding is reduced, and as a result the monitored picture is observed at a high speed on the receiver side.
