Title: Reflection type photoelectric detector
Inventor: OGAWA TATSUO
IPC: G01S17/02
Filed: 1978-05-02
Abstract: PURPOSE: To make possible stable detection corresponding to the change components of photodetector output without the effect of aging or other by trisecting the detection output in voltage at  the receiving of reflected light from the object to the detected and correcting upper and lower limit  threshold values according to the change in the intermediate voltage.   
     CONSTITUTION: When the reflected light of projection light by the object to be detected is received  in a photo detector 1, a detecting circuit 6 generates the trisected voltages by way of the resistances 9 thru 11 connected to the collector of a transistor 8 in correspondence to the intensity of the  reflected light. The intermediate value of these trisected voltages is delayed for the specified time  by a time constant circuit 4 and is applied to the positive and negative input terminals of operational amplifiers 2, 3 forming the upper and lower limit comparators of a change component detecting circuit 5. Thereby, the upper and lower limit threshold values of the comparators 2, 3  owing to environmental conditions, the aging of the photo detector 1, etc. are corrected. Hence,  either output of the comparators 2, 3 is processed in an integrating circuit 12 and level detecting  circuit 14 and the transistor 16 of an output circuit 15 for lihting a light emitting diode LED for  alarming is controlled, whereby the photo detection outside the upper and lower limit values is  stably accomplished without the effect of environmental conditions and aging.

Title: Manufacture of cadmium sulfide for electrophotography
Inventor: IKEDA TAKESHI
IPC: C01G11/02
Filed: 1980-04-22
Abstract: PURPOSE: To obtain cadmium sulfide for electrophotography with enhanced light attenuating characteristics by changing over the atmosphere in a process of calcining cadmium sulfide particles from an inert gaseous atmosphere to an oxygen-contg. atmosphere.  
     CONSTITUTION: In the first half of a process of calcining cadmium sulfide particles, while feeding an inert gas, the particles are doped with an activator such as metallic impurities. In the latter half of the process, by feeding an oxygen-contg. gas such as air, defects formed by the first stage calcination in the vicinity of the surface of the cadmium sulfide are compensated with oxygen by substitution. Cadmium sulfide obtd. by this method has less crystal defects, so when it is applied to a high-speed copying machine or the like, high electrostatic contrast and high sensitivity for electrophotography are attained.

Title: Flat fluorescent lamp
Inventor: HINOTANI KATSUHIRO
IPC: H01J61/30
Filed: 1986-03-12
Abstract: PURPOSE:To enable the reduction in size and weight, by providing a pair of electrodes extending perpendicularly to the direction of facing of a pair of flat glass plates. CONSTITUTION:Reinforcing glass rods 8, 8 are disposed perpendicularly to discharge electrodes 4, 4. Since the distance between the facing discharge electrodes 4, 4 and facing auxiliary electrodes 5, 5 is shorter at the side walls 4b, 4b of the discharge electrodes and those 5b, 5b of the auxiliary electrodes than the other portions thereof, the discharge start voltage at each of the side walls is lower than that at each of the other portions according to Paschen's law. Since the side walls have a protrusive form, an electric field is more likely to concentrate thereon. Therefore, discharge is more likely to take place at the side walls than at the other portions. As a result, the discharge is prevented from concentrating in the central portions of three sections partitioned by reinforcing glass rods 8, 8. The discharge is thus uniformed on the whole surface of a fluorescent lamp.

Title: Gold coated globular phenol resin for anisotropic conductive resin
Inventor: NAKABAYASHI AKIRA
IPC: H01B5/14
Filed: 1990-03-06
Abstract: PURPOSE:To obtain a conductive filler optimum for an anisotropic conductive resin excellent in conductivity, dispersibility and an elastic modulus by classifying a globular phenol resin to be coated with gold. CONSTITUTION:A globular phenol resin, where an average particle diameter of a primary particle is 1-30mu and at least 70% or more of the primary particles exist within a particle diameter range of the average particle diameter + or -30%, is coated with gold. One layer made of either nickel or silver is formed as a base layer (a first layer) for gold, and coated with gold as an outer layer (a second layer). If at least 70% or more of the primary particles are not present within the particle diameter range of the average particle diameter + or -30%, secondary coagulation is liable to occur, resulting in poor dispersibility. Consequently, it is difficult to obtain anisotropy in conductivity, thereby leading to an impossibility to cope with densification. Therefore, it is possible to obtain a high density with sufficient anisotropy in conductivity without any deterioration of the conductivity due to thermal pressing.

Abstract: PURPOSE:To execute polling at an extremely high speed by executing the polling basing on whether a data stored in a main memory means in a base station is new or not, and whether a data quantity exceeds a prescribed quantity or not. CONSTITUTION:While ''Is there a data display request?'' from a keyboard 2 is ''NO'', a device is held as it is. When ''Is there a data display request?'' becomes ''YES'', a command is outputted from the keyboard 2, a data stored in a main memory means 10, namely, ''Is there the car concerned in an object area?'' is decided. A data from a comparing means 6 is always counted by a counter means 12, and also stored in a temporary storage means 13, therefore, when a collected data in the counter means 12 does not exist, ''NO'' is obtained, and the operation is shifted to a ransmitting operation of a polling signal by the limiter means 14 and the command from the keyboard 2. When a data in the counter means 12 exists, ''YES'' is obtained, and subsequently, ''Is its data new or not?'' is decided.

Title: Carrier extracting circuit
Inventor: TANABE KENZOU
IPC: H03L7/08
Filed: 1981-04-10
Abstract: PURPOSE:To correct phase shift characteristics to variation in input frequency by providing a phase shifting circuit behind a PLL circuit. CONSTITUTION:A wave to be modulated applied to an input terminal 1 is applied to a phase comparator 3 through an amplitude controller 2. The phase comparator 3 outputs a voltage proportional to a phase difference between said signal and the output signal of a voltage-controlled oscillator 5, controlling its oscillation frequency. A phase difference between the input signal and the output signal of the voltage-controlled oscillator 5 depends upon the loop gain of a PLL circuit 8 consisting of the phase comparator 3, a loop filter and DC amplifier 4, and the voltage-controlled oscillator 5, and as the input singal varies in frequency, said phase difference varies. A phase shifting circuit 6 has characteristics for correcting the frequency-phase characteristics of the PLL circuit 8, compensating the phase shift of the output signal.
