Title: Mounting device for ceiling speaker
Inventor: KANZAKI YOSHIHIRO
IPC: H04R1/02
Filed: 1994-06-23
Abstract: PURPOSE:To bring a panel and a ceiling into close contact by folding a spring which makes a panel cover a ceiling hole through a holding tool. CONSTITUTION:A circular opening 32 is formed at the position corresponding to a ceiling hole 24 at the center of a main plate 28. A speaker 34 is mounted on the rear side of the main plate 28 so that it can amplify sound from the opening 32. The main plate 28 is integrally provided with two folding tools 36. The panel is large enough to cover the ceiling hole 24. A projection 50 is formed at the center parts in the forward and backward directions of the both ends. The other end of the spring is engaged with an engagement hole 52 which is formed on the projection 50. As a spring 40 is pulled to draw it from the ceiling hole 24, the panel is made up and covers the ceiling hole 24 when the spring 40 returns to the original state. In this case, the spring 40 is folded back by the folding tool 38.

Title: Air pressure regulator
Inventor: NAKANISHI KOJI
IPC: G05D16/16
Filed: 1986-07-15
Abstract: PURPOSE:To reduce the response delay by building a pilot valve, which controls the supply of a certain pressure by charging and exhaust, in a main valve for pressure control charging and exhaust of a pilot pressure to this pilot valve in accordance with the air pressure pulse obtained by a two-port solenoid valve. CONSTITUTION:The control command for pressure control to a main valve 20 is converted to air pressure pulses by two-port solenoid valves 30 and 31, and they are applied as the pilot pressure to a diaphragm chamber 29 to operate respective valve bodies. Thus, the linearity of pressure control is improved, and the pressure is accurately controlled, and two-port solenoid valves 30 and 31 are permitted to be small-sized and small-capacity, and a sufficient durability is attained through two-port solenoid valves 30 and 31 are small-sized because the pilot pressure is used for solenoid valves 30 and 31 and the supply air pressure is not directly controlled as conventional. Since air is discharged by a pilot operation type exhaust valve body 27 when the discharge pressure is higher than a set pressure, a higher relief capability is taken through the two-port solenoid valve 31 for exhaust is small-sized and small-capacity.

Title: High frequency oscillation circuit
Inventor: ABE SHUJI
IPC: H03B5/12
Filed: 1989-06-27
Abstract: PURPOSE:To take-out stable and large oscillation output power by taking-out an oscillating output from the collector of one differential transistor, to which positive feedback is loaded from a tuning circuit, in an oscillation circuit constituted by connecting the tuning circuit to a differential amplifier. CONSTITUTION:A choke coil L3 (a resistor is available as well) is connected to the collector of a transistor Q2, to which the positive feedback is loaded through a feedback capacitor C3, and an output terminal T of the oscillating output is connected to a connecting point between the coil L3 and collector. Namely, the load of a buffer amplifier(AMP) or mixer(MIX), etc., is connected to the collector of the transistor Q2. Accordingly, since an influence to be applied to an oscillation frequency by the fluctuation of a load input capacitor CL is reduced and a capacity value to be connected to the base of the transistor Q2 is also reduced, oscillation in a high frequency area (>=1GHz) is made easy as well.

IPC: G02F1/19
Filed: 1992-06-02
Abstract: PURPOSE:To surely eliminate unequal colors and to improve quality by repetitively impressing an AC voltage to a cell after sealing a dispersion into the cell. CONSTITUTION:An electric field is impressed to the dispersion 2 dispersed with anisotropic particles to change the orientation of the anisotropic particles, by which the light transmittance is controlled. After the dispersion 2 is sealed into the cell 1, the AC voltage is repetitively impressed thereto to eliminate the unequal colors.

Then, the oriented state and random state of the particles are repetitively executed if the impression to the AC voltage to the cell 1 is intermittentry executed and the unequalness of the oriented state and density of the particles existing in an initial period are presumed to be gradually eliminated by such motion of the particles and the unequal colors are presumed to be eliminated. Then, the unequal colors are easily and surely eliminated after sealing of the dispersion 2 or before shipping of the product.

IPC: H03M1/14
Filed: 1987-07-02
Abstract: PURPOSE:To reduce the variation of an analog input voltage by providing a switch which stays off at least while the analog input voltage is sampled by the voltage comparators of a second group between the switch group of plural pieces of the switches and the reference voltage impressing terminal of the voltage comparators of the second group. CONSTITUTION:All reference voltage supply routes connected to the voltage comparators A21-A2(K-1) of the second group through the switch group E1-EL are provided with the switches SW1-SWK-1, which turn on or off complementarily to the switches, included in the voltage comparators A2 of the second group respectively. Because these switches SW stay off at least while the analog input voltage is sampled by the voltage comparators A2 of the second group, the capacity of the switch group E is not transmitted to the input terminal of one side of the voltage comparators A2 of the second group, i.e., the analog voltage impressing terminal 16, and the variation of input impedance is reduced. Thus, the variation of the analog input voltage comes small.
