Title: Closed type refrigerant compressor
Inventor: SUDOU MASAYASU
IPC: F04B39/06
Filed: 1983-03-30
Abstract: PURPOSE:To make it possible to lower the temperature of each section of a compressor, by arranging pipes extending from the bottom of a closed casing, crossing over the lateral surface of the casing so that the compressor is cooled down with the use of air convection in the pipes. CONSTITUTION:Air in a pipe 9 which is adapted to be heated by lubrication oil 8 and coolant gas, comes up through the pipe 9, when the temperature of the air in the pipe 9 is raised. That is, air warmed in the pipe 9 climbs since low temperature air exists in the lower section of the pipe 9. Lower temperature air is introduced into the pipe 9 as indicated by the arrow when the warmed air is vented from the top of the pipe 9. The air introduced in the pipe 9, is then heated by lubrication oil and coolant gas filled in a closed casing 1, therefore, climbs under natural convection and is vented from the top of the pipe 9, thereby the temperature of each section of the compressor may be lowered.

Title: Antenna for small-sized radio equipment
Inventor: MATAI MASAHIRO
IPC: H01Q13/18
Filed: 1986-03-11
Abstract: PURPOSE:To secure the satisfactory communicating sensitivity even when the using condition of the small-sized radio equipment is changed by being equipped with at least two pairs of the one side short-circuiting microstrip type antenna having a mutually different exciting direction. CONSTITUTION:The first and second antennas 10 and 20 having a mutually different exciting direction are connected to a circuit board 40 of a radio equipment. The first antenna 10 is a one side short-circuiting microstrip antenna of a two-layer structure and the second antenna 20 is a one side short-circuiting microstrip antenna of a three-layer structure. For example, when the first antenna 10 is resonated to the electromagnetic wave of a transmitting side opponent station 103 and the electric power source is supplied to the first amplifier 50, the output signal from a wireless part 53 comes to be the low noise. This is decided by a data processing part 54, and an electric power source supplying circuit 52 is controlled so as to execute the subsequent electric power source supply to the first amplifier 50. Thus, the antenna used for receiving comes to be the first antenna 10 only, and the second antenna 20 is separated from the circuit system of the radio equipment.

Filed: 1983-03-28
Abstract: PURPOSE:To obtain an information converter which converts a digital data into a staircase wave having a modulated period for a data recorder/reproducer, by using a staircase wave generating circuit. CONSTITUTION:The staircase waves of different periods can be selected in accordance with 1 or 0 of the signal at a terminal Q which is obtained by latching a data signal (a) by a latching circuit 11. In other words, the half period T of the staircase wave is short and long when the data (a) is set at 0 and 1 respectively. This staircase wave is recorded on a magnetic tape 3 by a tape recorder 7. An output signal (c) is fed to a buffer 14 of a comparator 5 in the reproduction mode. At the same time, the top and bottom points of the signal (c) are held by a diode D5 and a capacitor C2 and the D6 and C3 respectively. Then the amplitude center potential of the signal emerges at a capacitor C4 through resistances R8 and R9. An operational amplifier 15 compares the signal with the amplitude center. Then it is possible to extract a square waveform (d) which has a short period to a signal 0 and a long period to a signal 1 respectively. Thus, the recording density is greatly increased.
