Abstract: PROBLEM TO BE SOLVED: To efficiently process difficult-to-cut ceramics, in applying cavity forming processing to silicon nitride ceramics by a diamond core drill to which high frequency vibration is applied, by selecting amplitude and rotational peripheral velocity within a predetermined range. SOLUTION: High frequency vibration is applied to a rotary diamond core drill 1 from the oscillator 2 connected to a high frequency generator 5 through a horn 3 and the diamond core drill 1 is supported by a support part 4 to be brought into contact with a sample 6. When the diamond core drill 1 in the processing apparatus thus constituted is brought into contact with the surface of the silicon nitride ceramics sample 6, a cavity is formed to the surface of the sample 6 by the rotation and up-and-down vibration of the drill 1 and perforation processing or groove processing can be applied. The vibration amplitude of a vibrator at this time must be set to a range of 10-40μm and the rotational peripheral velocity of the diamond core drill must be selected within a range of 2-7m/min.

Title: Liquid developing device
Inventor: NOBUSAWA HIROAKI
IPC: G03G15/11
Filed: 1989-02-10
Abstract: PURPOSE:To replenish the lack of toner contained in a developer by comparing the concentration of the developer detected by a concentration sensor with a set concentration of the developer and increasing the circulating amount of a circulating pump by the difference between them when the detected concentration is less than the set one. CONSTITUTION:A light emitting diode 7 provided in a developer tank 1 and the concentration sensor 5 composed of a phototransistor 8 and an amplifier 9 convert the concentration of the developer 10 in the developer tank 1 into a voltage value, which is compared with the concentration value previously set by a comparator circuit 13. When the detected voltage value is less than the set one, a pump driver 12 increases the circulating amount by the error output 11 of the comparator circuit 13. Thus, the lack or toner contained in the developer can be compensated.

Abstract: PURPOSE:To obtain an element isolation region comprising few step part on a surface of a semiconductor substrate by forming an insulating layer and a high-resistance semiconductor polycrystalline layer in a groove where an element isolation region is to be formed. CONSTITUTION:After forming a photoresist film 2 on a GaAs substrate 1, an opening part 5 is formed in the part where an element isolation region is to be formed and a groove 6 is formed by etching. Subsequently, a silicon oxide film 3 is formed over the whole substrate and then the silicon oxide film 3 except in the groove 6 is removed together with the photoresist film 2. when an epitaxial GaAs layer is grown, a polycrystalline GaAs layer 4A is formed on the silicon oxide film 3 in the groove 6 and a single crystal GaAs layer 4 is formed in the part where the GaAs substrate 1 is exposed. The polycrystalline GaAs layer 4A shows a high resistance and because its density is smaller than that of the single crystal GaAs layer 4, the film thickness is about 10 deg.C thicker than that of the single crystal GaAs layer 4. However, as the polycrstalline GaAs layer 4A grows from the level 0.1mum lower than the single crystal GaAs layer 4, an even element isolation region 7 can be formed as a result.

Title: Optical position detector
Inventor: TAKEDA HARUMI
IPC: G02B27/18
Filed: 1979-03-17
Abstract: PURPOSE: To obtain the optical position detector of high accuracy and high resolution by providing a reference position projection system within the optical system and compensating the measurement errors owing to the aging of photodetectors and external factors.  
     CONSTITUTION: The luminous flux from a light source part 10 is reflected only in the direction of a projecting lens 30 by a reflecting mirror 20 and the reflected light projected to the subject 60 generates an electric signal by a photodetector Lb on the photodetector 40 surface. Here, part of the transmitted luminous flux of the lens 30 is caused to generate a reference electric signal by a photodetector Ls  by a reference reflecting mirror 50. These signals are processed in an electronic counter device 70, whereby digital displaying is accomplished. Hitherto, Lb was made a reference value, i.e., zero point, but when the photodetector Lb displaces, it directly becomes a measurement error. If this (Lb-Ls) is made a reference value, the differences of addresses may be made constant irrespective of the displacement of the photodetector. Thereby, highly accurate position detection may be accomplished.

SOLUTION: A gradation is carried out so that the combination of sub-fields may be altered every frame to display one gradation, and the top and its lower bits (MSB, MSB-1) except the lowest bit (LSB) are severally divided into (2<n-1> -1)=3 and 1, (2<n-1> -1)=1 and 1 to form each sub-field in five sheets in all. A black circle in a table shows a picture element emission timing, for instance, in the case of the gradation 3, in an odd number frame, an emission is caused in time sub-fields of gradation LSB and MSB-1, and in an even number frame, the emission is caused in three sub-fields of the divided gradation MSB. The combination of sub-fields is varied every frame to cause the emission, and the emission timing of one picture element can be adjusted at random, and nonemission term during carrying therefore becomes various and a pseudo- animation outline can be prevented.
