Title: Optical asher
Inventor: KAWASUMI KENICHI
IPC: H01L21/30
Filed: 1988-04-13
Abstract: PURPOSE:To homogenize concentration of ozone on a wafer surface therefore uniformize an ashing rate by a method wherein positions of a number of nozzles which supply reaction gas and the position of a wafer are relatively changed during a processing period. CONSTITUTION:Ultraviolet light is irradiated via a synthetic quartz plate 10 on the surface of a wafer 1. The wafer 1 is mounted on a rotary stage 4 which is heated, and is rotated several tens of rotations per minute in a direction of the shown arrow, for example. Reaction gas containing ozone is supplied from a number of nozzles 2 provided on the synthetic quartz plate 10 and flows in a narrow flow gap 11 between the synthetic quartz glass 10 and the surface of the wafer 1. By relatively changing the positions of the nozzles 2 and the surface of the wafer 1 in time by shifting the rotation center of the rotary stage 4 during processing time or shifting the synthetic quartz plate 10, supply of ozone on the surface of the wafer 1 can be uniformized.

Title: Cassette case, unfolded plate for cassette case and metal mold for creasing
Inventor: KUBODERA TAKESHI
IPC: B31B50/25
Filed: 1992-04-09
Abstract: PURPOSE:To prevent heat-shrinkable wrapping film from being damaged by a method wherein edges, defining an opening, of the front part and the rear part of a cassette case meet common edges of the front part and the side parts and of the rear parts and the side parts at angles greater than 90 degrees. CONSTITUTION:An unfolded original plate for a cassette case is folded so that edges 201, 201, defining a case opening 17a, of the front part 2 and the rear part 2a of a cassette case 18a intersect, at an angle of 90 deg. or greater, edges 203 that are common to the front part 2 and the side parts 3a and to the rear part 2a and the side parts 3a that are superposed on each other. Namely, folding lines 203 are drawn toward points A2 that are positioned inside 1/100mm or more away from perpendiculars A-A1 extending from the points A on the bottom 4 to the edges 201 of the opening. Reinforcing parts 5, 5 are formed on both sides of the bottom 4. When the cassette case 18a is formed of the aforementioned unfolded original plate, the length of the opening is shorter than the length of the bottom, making the clearance between the opening and a contained cassette is almost nil. Thereby, warping of the case, arising from shrinkage of heat shrinkable film with which the case is wrapped, can be prevented, and damage to the film can be prevented.

Abstract: PURPOSE:To reset the output voltage rapidly to the original voltage by inserting a resistor in series with a field circuit by the operation of a voltage detecting relay during the period while the output voltage of an AC generator becomes higher than the prescribed voltage. CONSTITUTION:The output voltage of an AC generator 1 is detected by a transformer 3 for an instrument, compared by an automatic voltage regulator 4 with a reference voltage, a thyristor amplifier 5 is operated, and a current is supplied to a field circuit 2. A parallel circuit of a resistor 7 and a contact 8 is connected to the circuit 2, and the contact 8 is opened or closed by a voltage detecting relay coil 9 which is connected to a transformer 3.

Title: Branched pipe
Inventor: KANOU SHIYOUICHI
IPC: F01N99/00
Filed: 1978-07-20
Abstract: PURPOSE: To provide a branched pipe wherein a plurality of almost parallel branch passages are connected to a single main passage so that stress concentration does not take place even if vibration or the like is applied to the branched pipe, namely, that the pipe has a high durability.  
     CONSTITUTION: A dual exhaust pipe 56 comprises a branch passage part 50, a main passage part 52 and a connection part 54. The branch passage part 50 has two pipes 58, 60 coupled to each other through an intermediate section 62. The cross-sectional form of the branch part 50 is like spectacles. The cross-sectional form of the intermediate part between the branch passage part 50 and the connection part 54 is almost elliptic. Since these parts 50, 52, 54 are integrated with one another in the flowing direction of fluid, no stress concentration takes place even if the exhaust dual exhaust pipe is vibrated. The durability of the exhaust pipe is thus raised.

Filed: 1993-04-16
Abstract: PURPOSE:To recognize a state amount distribution at a reference position of a data processor by simultaneously sending sensor information for detecting the distribution in a room and information of a direction of a sensor to the processor. CONSTITUTION:A sensor installed in a room decides, when an infrared signal is sensed by photoreceivers 2a, 2b, 2e, 2d, an infrared signal incident direction, i.e., a direction of a state amount data processor of a transmitter from an intensity of the signal. After the direction information of the signal and a plurality of indoor state amount sensors (radiation temperature sensors) 4a, 4b, 4c, 4d are converted in summary to a signal, and then transmitted as an infrared signal to a room via a light emitting unit 3. A state amount data processor calculates, when the signal is sensed, a state amount distribution from its signal content. The information is output, for example, to an air conditioner. Thus, it can be used for an air conditioner for realizing a comfortable indoor environment.

Title: Fixation structure between spectacle frame and pads
Inventor: TANAKA KENJI
IPC: G02C5/12
Filed: 1987-04-14
Abstract: PURPOSE:To easily adjust pads finely by fixing right and left pads to respective metallic pad couplers, fitting the respective metallic pad couplers in respective pad metallic coupler fitting members projected from a spectacle frame nearby its bridge, and fixing them with screws. CONSTITUTION:The upper parts 11B and 12B of the respective metallic pad couplers 11 and 12 are sectioned in an L shape,and their lower parts 11C and 12C are sectioned cylindrically. The lower parts 11C and 12C which are sectioned cylindrically may be formed by boring or by bending expanded plates one after another. Through holes 11A and 12A are formed in the upper parts 11B and 12B of the metallic pad couplers 11 and 12. There is no bridge part between the metallic pad couplers 11 and 12, so the bridge of the spectacle frame 4 is only a bridge 4B. Consequently, the fine adjustment of the spectacle frame which is made matching with a spectacle user is facilitated and a decrease in the weight resulting from no bridge exceeds an increase in weight resulting from the metallic pad couplers 21 and 22, so the spectacles can be reduced in weight on the whole.
