Title: Video signal processing circuit in projection tv
Inventor: NISHIDA MASAMI
IPC: H04N9/31
Filed: 1988-09-13
Abstract: PURPOSE:To facilitate the correction of the trapezoidal distortion by changing a reading timing by a constant time and changing the frequency of a reading clock by a constant frequency at the time of reading out of a line memory. CONSTITUTION:From a reading control circuit 17, a reading permitting signal, in which a generating timing is delayed by a constant time for a prescribed H based on the counted output of an H counter 16, is generated. In a PLL circuit 18, a frequency-dividing ratio N is incremented for a prescribed H by the control of a frequency-dividing ratio control circuit 19, and thus, a reading clock, in which the frequency rises constantly for the prescribed H, is generated. For example, at the time of N=288, first 1H data fetched into a line memory 13 by the writing clock of a constant frequency 4fsc are read from the memory 13 by the reading clock of the approximately same frequency 4fsc. At the time of N=289 in a next 1H, a reading clock frequency is higher, and therefore, the signal outputted from a D/A converter 20 is time-base-compressed.

Title: Led collimator
Inventor: HAGAMI YOSHIHISA
IPC: G02B27/30
Filed: 1985-10-15
Abstract: PURPOSE:To convert light emitted from an LED into parallel light efficiently and directly, by converging the diffused light emitted from the LED through an optical lens, and providing a first stop made of synthetic resin and a second stop made of metal on a path after the optical lens. CONSTITUTION:The light emitting part of an LED 1 is located approximately at the focal point of an optical lens 2. The focal pint is located at a position, which is separated from the end of the optical lens 2 by about r/2, where (r) is the radius of the optical lens 2. Therefore, the considerable light of diffused light emitted from the LED 1 passes the optical lens 2. Of the light, which has passed the optical lens, the light rays, which have the large angle with respect to the cylindrical axis of a sleeve 5, are inputted and absorbed in a first stop 3 made of synthetic resin. The remaining light rays, which are not absorbed by the stop, are inputted in a second stop 4 made of metal. A part of the rays are absorbed in the second stop 4, and the other part is reflected and after all absorbed in the first stop 3. Thus, the light, which is emitted from the LED collimator, becomes only the light rays that are approximately in parallel with the cylindrical axis of the sleeve 5.

Abstract: PURPOSE:To obtain a photodiode which is high in sensitivity even to ultraviolet ray of 300nm in wavelength lambda by a method wherein an injection protective film of thermally oxidized SiO2 is formed on a P-tupe silicon substrate. CONSTITUTION:A thermal oxide film 2 tOX in thickness is formed on a P-type silicon substrate 1, a polysilicon film 3 is formed thereon, and the polysilicon film 3 is patterned through a photolithography technique to form a polysilicon mask 31 provided with a window. Then, arsenic ions are implanted into the substrate 1 through the in termediary of the thermal oxide film 2 using the polysilicon mask 31 as an implanting mask. An N-type injected layer 5 formed in the P-type silicon substrate 1 at a photodetective section 4 is set to 0.8mum or below in thickness through the control of the implanting energy concerned. Then, the P-type silicon substrate 1 is thermally treated in a heat treatment oven. By this setup, carriers generated by light are sufficiently restrained from being trapped and recombined by ultraviolet in a photodiode, so that the photodiode becomes high in sensitivity to ultraviolet ray 300nm or so in wavelength lambda.

Title: Beam loading monitor device for accelerator
Inventor: SUZUKI RYOICHI
IPC: H05H7/00
Filed: 1989-09-05
Abstract: PURPOSE:To detect a low-level microwave signal by providing a means feeding the emitter current and collector current and outputting the amplified signal from a collector only when the negative signal voltage is applied to an emitter. CONSTITUTION:The base of a transistor 4 is connected to the ground via a forward voltage bias power source 6, a collector is connected to the ground via a collector resistor 5 and a voltage source 3, an emitter is connected to the ground via an emitter resistor 7, and the signal from a dummy load is inputted via a coaxial cable 9. When the signal voltage is negative (V=-Vo), the voltage between the base and the emitter becomes the forward voltage or above. The nonlinear characteristic of the PN junction between the base and emitter is sufficiently steep at the point equal to the forward voltage, thus a current flows until the voltage between the base and emitter becomes the forward voltage, and the current value is I=Vo/R. The voltage V (=IR'=VoR'/ R) is generated across the collector resistor 5 at this time. The voltage is amplified to R'/R times, and the low-level microwave signal can be detected.

Title: Static electricity absorption type handset
Inventor: KOBAYASHI TERUO
IPC: H04M1/03
Filed: 1985-10-16
Abstract: PURPOSE:To eliminate static electricity charged on a human body by forming a part or all of a handset by a resin material of volume resistivity of 10<7>-10<10>OMEGA.cm and connecting the forming with an earth line of a semiconductor circuit driving a handset. CONSTITUTION:Since a part or all of the handset 7 is formed by a resin material having a volume resistivity of 10<7>-10<10>OMEGA.cm, the electricity is conducted slightly. When a user charged with static electricity grips the handset, the charged static electricity passes the handset slightly and flows to the earth line of the semiconductor circuit. Since the static electricity is flowed not in a short time as spark discharge, no unpleasant feeling is given to the user and the current due to the static electricity flows directly to the earth line, then destruction of the semiconductor circuit is precluded.

Abstract: PURPOSE: To realize a control wherein a constantly appropriate number of burners are in use with less variation by measuring a total quantity of fuel flow by using a value detected by a flow portion of each burner stage and controlling the number of the burners according to the total quantity of the fuel flow. CONSTITUTION: A plurality of stages, e.g. three stages, of burners 10 (10a-10c) are respectively connected to CWM (pulverized-coal/water mixed fuel) fuel feed lines having a flow meter 4 and a pressure transmitter 5 connected in this order. Four sets of CWM burners, for example, are parallelly connected downstream of the pressure transmitter 5. Four sets of the burners of a second burner stage 10b are always kept ignited for starting.

In accordance with the increasing amount of the CWM fuel flow which corresponds to the increase of the load, the burners are ignited in an igniting sequence.
