Title: Electricity charger
Inventor: MASUDA SENICHI
IPC: B03C3/00
Filed: 1978-12-25
Abstract: PURPOSE: To uniformly charge an object with a large theoretical quantity of electricity in a short time, by exciting a corona discharge electrode by a voltage separate from a main voltage which is applied between the corona discharge electrode and another electrode facing it.  
     CONSTITUTION: A dust-containing gas introduced into a box 2 through an inlet port 4 in the direction of an arrow 5 is released to the outside through an outlet port 6 in the direction of another arrow 7. A-A' shows a virtual plane between facing electrodes 1, 1'. Strip-shaped corona discharge electrodes 9, 9', ... having projections 8 are vertically supported and insulated at their tops and bottoms on insulators 10, 11 so that the corona discharge electrodes are located on the virtual plane. Every other corona discharge electrodes are connected to each other through common wires 12, 13 so that all the corona discharge electrodes are divided into two groups. An excitation-type corona discharge electrode system 14 is thus formed. A high AC voltage is applied to both the groups of corona discharge electrodes from an exciting power source 15. A main high DC voltage, which is negative as to the grounded facing electrodes 1, 1', is applied to the corona discharge electrode system 14. This results in charging particles to a prescribed level at a very high speed.

Title: Gas sensor
Inventor: KUYAMA HIROKI
IPC: G01N27/12
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To enhance the thermal stability of a gas sensor which uses a conductive polymer membrane. SOLUTION: Two comb-shaped electrodes 3, 3 are formed on a glass substrate 1, and a conductive polymer membrane which is composed of poly(3'-n-octyl-2,2'; 5',2"-terthiophene) is formed on the surface of the electrodes 3, 3 as a sensitive membrane 7. The conductive polymer membrane is doped with FeCl3 as a dopant. Since side chains exist every two residual groups in the poly(3'-n-octyl-2,2'; 5',2"-terthiphene), a spatial margin in which the dopant exists is obtained. In addition, since the side chains are situated regularly as compared with poly(3'-n- octyl-2,2'-bithiophene), the random property of the distribution of the dopant is reduced. When the poly(3'-n-octyl-2,2'; 5',2"-terthiphene) is used for the sensitive membrane, the thermal stability of a gas sensor is enhanced.

Abstract: PURPOSE:To prevent appearance from being impaired by making the periphery of a sink difficult to be stained and making work in the sink easy to perform. CONSTITUTION:A dewatering rack 2 is provided to the side of the sink 1, and a water receiving tray 3 is also arranged underneath the dewatering rack 2.

Title: Fan connection state detecting system
Inventor: SAKAI HARUHIKO
IPC: G06F1/00
Filed: 1988-07-02
Abstract: PURPOSE:To identify a normal state, a disconnected state of a fan and a fault state of the fan itself through one signal line by providing the title system with an oscillator having frequency higher than a rotary pulse. CONSTITUTION:Usually, a fan pulse signal S1 outputted from a rotary pulse detecting means 1 is synthesized with a pulse signal S3 generated from the oscillator 5 by a gate means 2 and a waveform such as a signal S1' is outputted. Thereby, a signal inputted to a deciding circuit 4 through a gate means 3 goes a high frequency pulse group having a fixed period like a waveform S2. In case of an unconnected state, no signal is applied to a connecting part, so that the signal inputted to the circuit 4 through the gate means 3 continues the 'L' state like a waveform S2'. When the fan itself fails, signal S1 continues 'H' or 'L', so that the signal inputted to the circuit 4 goes a waveform S2''. Thereby, the waveform S2'' can be discriminated from the continuation of 'L' at the time of the unconnected case and the deciding circuits can identify both the signals.

Abstract: PURPOSE:To realize a pipeline type A/D converter realizing a high speed conversion rate. CONSTITUTION:A latch circuit 16 is inserted between a sub A/D converter 12 and a D/A converter 15 in the pipeline type A/D converter.
