Title: Vertical field-effect transistor
Inventor: SHIDA NAOYUKI
IPC: H01L29/08
Filed: 1991-01-28
Abstract: PURPOSE:To prevent the ON-resistance of a vertical field-effect transistor from being increased even if the specific resistance of an epitaxial layer is increased and to contrive to increase the breakdown strength between a source and a drain by a method wherein a one conductivity type buried layer of an impurity concentration higher than that of a first region formed separately of a base region is provided in the surface of a drain region directly under a gate electrode. CONSTITUTION:A channel is generated on the surface of an N-type base region 4a held between a P<+> source region 5 and a P<-> epitaxial layer 3 by applying a negative voltage to a gate electrode 7 and when holes flow to a drain electrode through the tunnel, they pass through a P<+> buried layer 2a. As a result, the holes flow vertically more than those in the case of a conventional vertical field-effect transistor and an ON-resistance of this vertical field-effect transistor becomes small by the amount of a reduction in a current path. Thereby, even if the specific resistance of the epitaxial layer is increased, the ON-resistance becomes smaller than that of the vertical field-effect transistor of a conventional structure and a breakdown strength between a source and a drain is increased.

IPC: H05B6/68
Filed: 1994-01-28
Abstract: PURPOSE:To keep the filament current at a proper level even when the output of an inverter device for feeding a driving current to a magnetron is made extremely small. CONSTITUTION:The power of a magnetron 12 is fed from an inverter device 1 through the secondary winding 2a of a high-voltage transformer 2, and the filament current of the magnetron 12 is fed from the auxiliary secondary winding 2b of the high-voltage transformer 2 through a coil 14.

Abstract: PROBLEM TO BE SOLVED: To ensure running stability during steering. SOLUTION: In order that the response of a yaw rate with respect to the change of a steering angle δt conforms to the aimed response, a moment in the yaw direction is applied to a car body, through the correction of torque commands TR and TL to motors 12R and 12L.

Title: Dag applying method and device for external surface of cathode-ray tube
Inventor: HIRAYAMA KAZUNARI
IPC: H01J9/20
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To provide a DAG (R) applying device for an external surface of a cathode-ray tube which stably obtains a DAG applying condition without generating blurring and sagging of DAG relating to wearing of an applying roller. SOLUTION: A diameter of a DAG applying roller 16 is measured by a roller diameter measuring means 23. A moving locus setting the roller 16 so as to maintain a prescribed applying condition relating to an external surface of a cathode-ray tube 11 is automatically changed corresponding to decrease of the roller diameter according to wearing. An adhesion condition between the roller 16 and an external surface of the cathode-ray tube 11 can be always maintained in a proper condition. Without generating blurring of the DAG 15 due to decrease of a collapse margin of the roller 16 and sagging of the DAG 15 due to an excessive collapse margin of the roller 16, a good applying condition of the DAG 15 is stably obtained.  Necessity for stopping a production line and increasing a replacement frequency of the roller 16 is eliminated, so as to improve production efficiency of the cathode-ray tube 11, so as to almost prevent generation of uselessness.

Title: Black phenolic resin molding compound
Inventor: FUKUSHI HIDEMI
IPC: C08L61/00
Filed: 1981-01-22
Abstract: PURPOSE: The titled compound which is free from flying of any colorants, remarkably improves a working environment and makes the use of conventional black colorant and plasticizer completely or partially unnecessary, which is prepd. by adding carbon black used in "sake" brewing to a phenolic resin molding compound.  
     CONSTITUTION: 1W10wt% (based on the total molding compound to be obtd.) carbon black used in "sake" brewing is added to a phenolic resin molding compound. A black phenolic resin molding compound for use in wiring instruments,  electrical appliances and household utensils is obtd. Although a conventional  black colorant such as carbon black is easily flyable and is difficultly handled,  the carbon black used in "sake" brewing never flies and is easily handled because it contains 40W80% alcohol. Thus, the cost reduction becomes possible by  making the use of conventional black colorant or plasticizer completely or partially unnecessary.

Title: Current bias circuit
Inventor: YATSUGI TOMISHIGE
IPC: H03K5/13
Filed: 1987-01-20
Abstract: PURPOSE:To accurately compensate the temperature characteristics of a load by forming a current mirror circuit by 1st and 2nd npn type transistors(TRs) and connecting the connector of the 1st npn TR to the collector of the 2nd pnp TR. CONSTITUTION:The collector current I1 of a TR 6 is slightly set up so as to be almost equal (up to about twice) to the collector current I1 of a TR 11 by a resistor 8. Consequently, dispersion is not almost generated in current amplification between TRs 6 and 11 and the characteristics of voltage to collector current between the bases and emitters of TRs 6, 11 and the current I1 can be also accurately set up to a prescribed value by setting up the value of the current I1 accirately. A current I1 can be set up to a sufficient large value as compared with the current I3. Since the value of the current I2 can be accurately set up by setting up the value of the sufficiently large current I3 accurately, even if the collector current I2 of a TR 5 is a slight current, the collector current I1 of the TR 11 can be also accurately set up.

Abstract: PURPOSE:To dispense with an expensive battery and to maintain a white balance even at the time of turning off a power source by storing a set value to decide the gain of a gain control means to change the gain of a chrominance signal into a memory exclusive-use for reading to be electrically writable. CONSTITUTION:When the power source of a device is turned off and the power source is inputted again, white balance data DR and DB at addresses at which they are written last are referred to by a CPU 40, and they are sent to variable gain amplifying circuits 34 and 35. Namely, a condition in which the white balance is obtained last is maintained. Namely, a P(Programmable) ROM 50 necessary for originally storing a program to operate the CPU 40 is utilized, and the white balance data are stored in the unoccupied area. Thus, without using the expensive battery and adding an EEP(Electrically Erasable and Programmable) ROM, the white balance data can be maintained even when the power source is turned off.
