Abstract: PURPOSE:To miniaturize a rectifier and multiplier. CONSTITUTION:Semicircular shield electrodes 41-4n are arranged in opposition to likewise semicircular RF (high frequency) electrodes 31-32, and capacitance is formed between these electrodes.

Title: Dehumidifier for compressed air
Inventor: SUZUKI SEIICHI
IPC: B01D53/26
Filed: 1990-09-19
Abstract: PURPOSE:To prevent the mixing of condensed water droplets into the compressed air to a vortex tube by arranging a baffle member around the compressed air inlet of the vortex tube and arranging a vortex head apart from the inner peripheral wall and bottom of an air cooling chamber. CONSTITUTION:An annular baffle member 72 extending toward the bottom wall 42-2 of a cooling chamber 42 is provided to a vortex head 19. Consequently, the water droplets condensed on the surface of the head 19 are dropped as shown by F toward the bottom wall 42-2 from the lower end of the member 72 and separated. The head 19 is arranged in the chamber 42 apart from the inner peripheral wall 42-1 and bottom wall 42-2, and hence the droplets are hardly transmitted to the head 19 from the walls. The mixing of condensed water into the air introduced into a compressed air inlet 24 is prevented in this way. Accordingly, dehumidification efficiency is improved.

Title: Sticky screw
Inventor: SATOMI SHINJIRO
IPC: F16B23/00
Filed: 1989-09-22
Abstract: PURPOSE:To prevent falling-off of a screw from a screw driving means such as a driver and the like by coating sticky material in a slot or a hole of a screw head. CONSTITUTION:A sticky screw 2 is made by coating sticky material A in a slot 8 of a head 6 of a minus screw 4. As to sticky material, generally used sticky material such as EM series, solution type series and the like, e.g., cemedine CT-1300 and others are enough for this purpose. As to screws, a plus screw and a hexagon socket head cap screw and the like are also appli cable. When a screw driver is inserted into the slot or the hole of the head of the sticky screw, the sticky screw adheres to the screw driver through the sticky material. So, when the is fastened to the base surface, the screw does not fall down. On the other hand, when the screw driver is removed from the screw, resistance is low.

Abstract: PURPOSE:To design adaptation to an LSI controlling the number of using times of condenser by comparing terminal voltage of condenser in CR circuit with the reference voltage, by generating the output signal with equal pulse width having horizontal synchronous period, and by making it return to the 1st latch part. CONSTITUTION:The latch part 1 generates outputs Q following input a, b, output signal B of the latch part 1 rises when the input/output signal A is in low level and output signal D of comparator part 4 is in high level, and falls when next input signal rises. Switching part 2 is in low level when signal B is in high level. Terminal of condenser C in CR circuit 3 is grounded, and output signal C is in low level. When the signal B gets in low level, switching part 2 gets in high level, and the condenser C in CR circuit 3 is charged from electric source Vcc through resistance R. Output signal C rises slantly, and CR circuit 3 becomes integral circuit. Horizontal synchronous period pulse can be separated from the composite synchronous signal by comparing the signal of the charged and discharged wave length obtained by controlling charge and discharge of CR circuit by switching with the reference value.

Abstract: PURPOSE: To obtain an alloy contg. no Cd as a toxic element and having corrosion resistance better than that of the known alloy contg. Cd by adding Zn with any of lead, Al and rare earth metals or Mn or Al, rare earth metals and Mn by specified amounts.  
     CONSTITUTION: This Zn alloy for an electrochemical battery can is the one having a compsn. contg. any of 0.05 to 0.8% Pb, 0.005 to 1% Al and 0.0005 to 0.1% rare earth metal or the mixture thereof (REM) or 0.005 to 1% Mn or 0.005 to 1.5% mixture of Al, REM and Mn, and the balance Zn. In the case where the content of Pb is less than the lower limit, the alloy is made too brittle, and in the case it is more than the upper limit, its mechanical strength is made insufficient, and there is a fear of causing the problem of corrosion. When Mn is not present, in the case the contents of Al and REM are less than the lower limits, its mechanical strength and corrosion resistance are insufficient, and in the case they are more than the upper limits, a two layer structure is formed. When Mn is contaied alone and Al+REM+Mn are contained, in the case their contents are less than the lower limits, its mechanical strength and corrosion resistance are made insufficient, and in the case they are more than the upper limits, cracks are generated at the time of rolling.

Filed: 1984-11-26
Abstract: PURPOSE:To prevent the unnecessary scanning of a recording medium and to reduce the deterioration in the record medium at a special regeneration mode by responding to the mode setting means to control a guidance means and by changing a positional relation against the regeneration means of the recording medium. CONSTITUTION:When the recording mode is set, a mode detector 11 detects it, and a signal corresponding to it is outputted to a guide post driving device 7. In case of performing a special mode regeneration, a mode setting device 10 is set on a still regeneration mode, the guide post drive device 7 is actuated through the mode detector 11 to move a tape guide post 5. Thus, the wound angle of a magnetic tape (t) becomes enough 180 deg., and the audio area of the magnetic tape and a record regeneration head 4 falls in non-contact condition. Therefore, the audio area of the magnetic tape (t) isn't scanned, and only the necessary video signal is taken out. Thus, the prevention of the unnecessary recording medium from scanning and the prevention of the deterioration of the recording medium can be achieved.
