Title: Clean booth apparatus
Inventor: NISHIYAMA MASAMITSU
IPC: F24F7/06
Filed: 1993-11-04
Abstract: PURPOSE:To secure and maintain cleanness on the side of a clean room by providing an inlet port of a blowing device at a lower part of a clean booth apparatus and on its surface facing the external side of the clean booth. CONSTITUTION:When a circulating fan 3 is actuated, air in a clean room 10 is sucked through an air inlet port 7 and sent into an air conduct chamber 1 via an air conduct duct 11 (the arrow B). After passing through a filter 8, air sent into the air conduct chamber 1 is blown into a clean booth through air outlet ports 9 to descend through the inside of the booth (the arrow C) and discharged from the underside of the foot of a vinyl sheet 5 (the arrow D). In this case, since the air inlet port 7 is formed at the lower part of the outer side surface of the air conduct duct 11, discharged air is sucked through the inlet port 7 in the state of a horizontal air stream, and dust on the floor face 10A of the clean room is hardly dragged and sucked. By this method, cleanness on the side of the clean room 10 is secured and maintained.

Title: Evaporator for absorption-type refrigerating machine
Inventor: MATSUMAE KAZUNORI
IPC: F28D3/02
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To enhance heat transfer performance by a method wherein a spacer is attached between adjacent upper and lower heat exchanger tubes along the length thereof and a liquid accumulating part is formed near a joint part of the spacer and the lower heat exchanger tube to prevent the expansion of a dry part of a refrigerant liquid flowing down on the surface of the heat exchanger tubes. SOLUTION: A refrigerant liquid sprayed and dropped from above the top stage heat exchanger tube 31a by a refrigerant liquid spraying device flows down circumferentially on the surface thereof to reach a spacer 19. The refrigerant liquid flowing down on the spacer 19 runs down continually getting together in the longitudinal direction of the heat exchanger tube 31b though a part thereof is accumulated into a liquid accumulating part 19a formed at a joint part of the heat exchanger tube at the subsequent stage and the spacer 19. Even if a dry part exists at a corresponding position of the surface of the subsequent stage heat exchanger tube 31b, the part is narrowed by the refrigerant liquid flowing down from the liquid accumulating part 19a. This improves wettability of the heat exchanger tubes Thereby achieving a higher heat transfer performance.

Title: Video disk player
Inventor: TENMA TETSUYA
IPC: G11B27/10
Filed: 1988-11-01
Abstract: PURPOSE:To use an integration circuit for any video disk player by processing a signal having a frequency 4fsc four times of that of a chrominance subcarrier being a reference to generate a reference horizontal synchronizing signal. CONSTITUTION:An oscillated frequency from a voltage controlled oscillator VCO 16 varies with a phase difference between a reference frame pulse and a reproduced frame pulse around the frequency 4fsc. The output of the VCO 16 is fed to a frequency divider 21 via changeover switches 17, 18 and frequency- divided to be a reference horizontal synchronizing signal, which is fed to a spindle servo circuit 8. As a result, the rotating speed of the spindle motor 2 is accelerated/decelerated in response to the phase difference between the reference frame pulse and the reproduced frame pulse. When the reproduced phase is advanced, the oscillation frequency of the VCO 16 is lowered and the reproduced phase is delayed by a loop, then both the frame phases are changed in the coincident direction. Thus, since the signal of the frequency 4fsc is a reference signal of almost all video equipments, the circuit is applied to any video disk player.
