Title: Lighting equipment
Inventor: KOBAYASHI KAZUTOSHI
IPC: F21V14/00
Filed: 1991-03-31
Abstract: PURPOSE:To illuminate a structure efficiently and prevent the glare from striking against pedestrians and so on by arranging a louver so as to cover a low reflectance part and an approximately half of a light projecting opening on the opposite side of this low reflectance part. CONSTITUTION:A low reflectance part 10 is arranged in a part irradiated by the direct light from a lamp 5, and is formed by carrying out low reflectance finish on the inside surface of an equipment body 1. A louver 11 is also arranged so as to cover an approximately half of a light projecting opening 2 on the opposite side of the part 10, and is arranged in its slant posture so as to cover the lamp 5 when seen from the pedestrian side. The opposite surface to the unit 10 of the louver 11 is formed further to have low reflectance (provided that high diffusibility), so that the lowering of equipment efficiency can be prevented. A lighting equipment constituted in this way is embedded on the side of a footpath and so on, and in the case of illuminating a structure, the glare striking against pedestrians can be prevented by means of the part 10 and the louver 11, and the equipment efficiency can be also heightened since the lamp 5 side of the louver 11 is formed to have high diffusibility.

IPC: B30B9/20
Filed: 1990-04-06
Abstract: PURPOSE:To allow the dehydration and compression treatment of garbage by energizing a sliding plate outward at all times so that the front end of the sliding plate pressed to the inner peripheral surface of a treating machine body in contact therewith is emerged and submerged to and from the outer peripheral surface of a rotary. CONSTITUTION:The outer peripheral surface of the rotating rotary 3 is provided with a garbage feed port 112 and a garbage discharge port 113 eccentrically both 3, 1 with each other in such a manner that both come into contact only with the inner peripheral surface of the treating machine body 1 between these ports. A sliding groove 32 is formed on the rotating rotary 3 from the outer peripheral surface toward the inside. The sliding plate 4 is fitted into the sliding groove 32. The sliding plate 4 is held energized at all times toward the outer side by an elastic body 5 so that the front end of the sliding plate 4 pressed to the inner peripheral surface of the treating machine body 1 in contact therewith is emerged and submerged to and from the outer peripheral surface of the rotary 3.

Patent JP-S63259477-A (JP)
Title: Voltage supply circuit
Inventor: FUKUDA MINORU
IPC: H03K5/08
Filed: 1987-04-15
Abstract: PURPOSE:To supply a specified value of pulse voltage of a correct ground level or the like, by generating an output voltage corresponding to a first voltage during a specified period when a voltage is changed in a pulse between a third voltage between first and second voltages and a fourth voltage biased in the opposite direction to the second voltage, not the first voltage. CONSTITUTION:An amplifier 20 receives first and second voltages V1 and V2 as working voltage, and a signal generation means 12 receives a third voltage V3 between the first and second voltages and a fourth voltage V4 biased in the opposite direction to the voltage V2, not the voltage V1, as input signal. When an output voltage C of the means 12 is a negative voltage V4, the output voltage D of the amplifier 10 tends to fall down a an negative level as the voltage V4 is below the working voltage V1 of the amplifier 10, but it will not be down below the ground voltage because the emitter of a transistor 26 is grounded. Thus, no current flows through a resistance 28 for current detection and so a negative power source terminal voltage V1 of an operational amplifier 14 is turned to the ground voltage. In other words, the saturation of the amplifier 10 enables the supply of a pulse voltage of correct ground level solely depending on the working voltage of the amplifier 10.

Title: File control system
Inventor: YOSHIDA KAORU
IPC: G06F12/00
Filed: 1988-04-15
Abstract: PURPOSE:To avoid production of an incomplete file by writing a changed file into an idle area of a system data base and then changing the address of a file control table into the address which is written into the changed file. CONSTITUTION:When the file of a system data base is changed, the changed file is written first into an idle area of the system data base. Then the address of a file control table 11 is changed into the address where the changed file is written from the address where an original file is written. Thus the address of a file control table 21 shows the address of the unchanged file despite occurrence such a fault where a power supply of a device is cut while the changed file is written.

Title: Vane type air pump
Inventor: KANEDA HIROSHI
IPC: F04C18/352
Filed: 1983-05-26
Abstract: PURPOSE:To reduce noise by sucking air into a discharge chamber with the aid of an arced face on a projection formed at the inlet edge part of a discharge chamber at the retraction side of a vane so as to reduce the quantity of air to be collected and jammed into a slit opening by a rotor. CONSTITUTION:The vane-retraction-side edge part of the inlet 32 of a discharge chamber is shaped in the form of a projection 38 which is continuously bulged from a land part L and the projection 38 has an arced face 37 swelling towards the inside of the discharge chamber 30. The arced face 37 of the projection 38 at the inlet 32 of the discharge chamber 30 accelerates the speed at which air flows along the face 37, thereby reducing the pressure around the face 37. As a result, the quantity of air to be collected and jammed into the clearance between rotor 7 and a land L may be reduced due to efficient suction thereof into the discharge chamber 30. Consequently, the quantity of high pressure air inside an opening 18 is decreased to reduce noise produced when it is discharged into the outlet 31 of a suction chamber 29.

Title: Output circuit
Inventor: KOJIMA MICHIAKI
IPC: H03K19/0944
Filed: 1982-06-01
Abstract: PURPOSE:To increase the permissible range of input information, by reducing an output current in output transition and a grounding noise of an inductance without varying the direct current ability of an output transistor (TR). CONSTITUTION:The driving ability of an output buffer circuit B is lowered below the driving ability of an output buffer circuit A to a 1:1 ratio. When the output of the output buffer circuit A drops to a low potential ''0'' and the output of the output buffer circuit B rises to a high potential ''1'', and when an output information terminal Dout has transition from the high potential ''1'' to the low potential ''0'', the driving ability of the output buffer circuit B is lower than the driving ability of the output buffer A, so output current variation dI/dt decreases, reducing a grounding noise dV. To decrease the driving ability of the output buffer circuit B most simply is that the width W of the channel of a depletion type TRQ5 is reduced (with the channel length unchanged). Consequently, the delay of a rising time, i.e. an increase in dt of dI/dt is realized.

When a control section 42 decodes the pulse code signal to be a recording operation signal, a recording section 19 is set to the recording mode and enters the recording state. A voice signal is given to a recording microphone 46 and a radio transmission section 40 modulates the signal into a prescribed radio frequency and the radio wave is sent from a transmission antenna 41.  The radio wave is received by a reception antenna 37 of the voice notice device main body 30 and demodulated into a voice signal by a radio wave reception section 39, recorded on a recording section 19 as voice information and stored in a memory section 20 as voice data.
