Title: Apparatus and method for sampling of analog signal voltage
Inventor: RAKUSUMI NARAYANAN SANKARANARA
IPC: H01L29/762
Filed: 1991-05-21
Abstract: PURPOSE: To improve a sampling device for an analog signal voltage. CONSTITUTION: A small number of charge single-body source regions 10 in a semiconductor main body 1 are clocked in phase with a charge transfer gate 6. Consequently, a metering potential well formed of a metering electrode 4 is filled with carriers through a DC gate 5 to alternate predetermined levels. Excessive carriers from it are drawn back through the DC gate. The remaining carriers leave through the transfer gate. To improve high-frequency operation, an extremely short gate 20 on it is prepared between the DC gate and metering well, and the gate on it is clocked in an opposite phase from the source region 10 and transfer gate 6. Consequently, a potential barrier which rises, when the excessive carriers are drawn back is created.

Title: Electromagnetic focusing cathod ray tube
Inventor: FUKUDA KIYOUHEI
IPC: H01J29/68
Filed: 1980-10-17
Abstract: PURPOSE:When moving a magnetic field regulating mechanism in the direction where the focus fiedl will be stronger, to prevent the deterioration of the temperature variation compensating characteristic even when the field strength is varied, by making such that the ratio between volume and the surface area at the portion of a temperature variation compensating mechanism which isn't lapped over the field regulating mechanism will decrease gradually. CONSTITUTION:A temperature variaton compensating mechanism 6 made of uniform magnetic steel is fixed to the outercircumference of a permanent magnet 2 or a magnetic field generating means, while a tubular fiedl regulating mechanism 5 made of soft ferromagnetic material is located movably in axial direction against the next section 1 of a cathode ray tube bulb. Consequently when said mechanism 5 will move in the direction where the focus field will be stronger, the ratio between the volume and the surface area at the portion of the compensating mechanism which lapped over the regulating mechanism 5 will decrease gradually. In other word the flux amount shunted to the mechanism 5 in accordance to the movement is reduced, while the flux amount passing at the non-overlap section is also reduced thereby the thickness of the uniform magnetic steel is made thin. Consenquently the temperature variation compensating characteristic will not deteriorate even if  the field strength is varied.

Title: Photoelectric type smoke sensor
Inventor: NAKAMURA TAKEHIRO
IPC: G08B17/10
Filed: 1983-08-09
Abstract: PURPOSE:To provide a sensor which is compact and easy to assemble and has improved accuracy by forming a photodetector which receives the reflected light scattered and reflected by smoke and a photodetector which compensates the output of the photodetector to the same semiconductor chip. CONSTITUTION:Smoke is passed freely in a case 1 by a slit 11 formed to a sensor case 1 and external light is shielded. If no smoke exists, the light emitted from a light emitting diode 4 is made incident directly on a photodiode 52 formed to a semiconductor chip 5. On the other hand the top surface of a photodiode 51 is covered by an electrode 51a and therefore the direct incidence of the light thereon is prohibited and only the reflected light reflected by the inside wall, etc. of the case 1 is made incident thereon. When the smoke flows into the sensor, the light is effectively scattered and reflected by the fine particles P of the smoke and quantity of light incident on the photodiode 51 increases sharply. The output of an amplifier 72 is thus made larger than the output of an amplifier 73 then a comparator 74 operates and a smoke detection signal is outputted from a signal generating circuit 75.
