Title: Burner for pulverized coal
Inventor: SEKIGUCHI YOSHITOSHI
IPC: F23D1/00
Filed: 1985-03-20
Abstract: PURPOSE:To permit stabilized combustion of pulverized coal even when the multi-combustion rate of assist fuel oil is reduced extremely by providing a flame stabilizing member. CONSTITUTION:A secondary air injection nozzle 2 is provided concentrically outside of a pulverized coal and primary air injection nozzle 1. The cylindrical flame stabilizing member 10, protruded so as to surround at least the end section of a clearance between both nozzles 1, 2 and the clearance 13 between the secondary air injection nozzle 2 are made larger than the clearance 14 between the primary air injection nozzle 1. In this case, the pulverized coal and primary air are ignited in the flame stabilizing member 10 and secondary air is also injected from the auxiliary secondary air injecting port 14, however, the amount of secondary air is small and combustion temperature is not reduced whereby the flame can be held in the flame stabilizing member 10. According to this method, the secondary air from the auxiliary secondary air injecting port 14 flows along the inside surface of the flame stabilizing member 10 and adhesion of pulverized coal, ash or the like may be prevented.

IPC: G01L9/00
Filed: 1985-03-22
Abstract: PURPOSE:To eliminate the error due to an ambient temperature in adjusting the zero point and to prevent the mutual interference of the zero point adjustment and the span adjustment by impressing, to an amplifier, the bias voltage related to the voltage source to impress the prescribed voltage to the shear- shaped gauge formed at the distortion generating part of the semiconductor diaphragm, and adjusting the zero point. CONSTITUTION:In the length-wise direction of a shear-shaped gauge 8 formed at the distortion generating part 3 of the semiconductor diaphragm, electric power source edges 9 and 10 are formed, and here, the prescribed voltage is impressed. Output edges 11 and 12 of the shear-shaped gauge 8 are connected to an amplifier Q2, and the amplifying output is connected successively through resistances R11 and R13 to amplifiers Q3 and Q4. A zero point adjusting means composed of a variable resistance R16 impresses the bias voltage related to the voltage of the voltage source to an amplifier Q3, adjusts a zero point, and a span adjusting means composed of a variable resistance R14 changes the feedback voltage of an amplifier Q4, and adjusts the span. Thus, even when the zero point is adjusted, the error due to an ambient temperature, etc., does not occur.

Abstract: PURPOSE:To prevent the false operation of a relay, etc. mounted to a front of a door, by fixing electrical machinery and apparatus generating vibration into a simple unit, and by fastening the unit into a frame of this enclosed switchboard through a vibration-proof device. CONSTITUTION:A simple unit 10 forming a breaker chamber 2 is fixed to a frame 1' of an enclosed switchboard 1 through vibration-proof rubber 11. Parts for transmitting vibration by the breaker 2, such as, main circuit disconnecting portions 5, nuts 7 for pulling-out screws, etc. are fixed at the fixed locations of the unit 10 while the main circuit disconnection portions 5 and conductors 13 are connected by means of flexible conductors 12. Thus, the false operation of a relay, etc. installed to a surface of a door 4 due to vibration can effectively be prevented because vibration by the make-and-break of the breaker 2 is absorbed by means of the vibration-proof rubber 11 between the unit 10 and the frame 1'.

Filed: 1988-03-11
Abstract: PURPOSE:To attain the high-speed character font development to a bit map memory by providing a cache memory between a two-dimensional rectangular region memory transfer circuit and a character generator. CONSTITUTION:The two-dimensional rectangular region memory transfer BIT- BLT circuit 13 reads the character font out of the character generator 11, writes the same into the bit map memory 14 and displays the same on a CRT display 15. The character font address of the BIT-BLT circuit 13 is compared by the cache memory 12 and is read into the BIT-BLT circuit 13 through a data bus 19 if said address exists in the cache memory. The font which does not exist in the cache memory is accessed to the character generator 11 and the font data is stored in the cache by the data bus 18. Said data is written into the BIT-BLT circuit 13 as well. The high-speed character font development is thus enabled.

Abstract: PURPOSE:To form a base region, etc. with high precision by using a polycrystalline Si film shaped onto an SiC film as a base leading-out electrode as the shape of the polycrystalline Si film is kept as it is. CONSTITUTION:A polycrystalline Si film 10 is formed selectively onto an SiC film 7. When film thickness in 5,000Angstrom  is shaped at that time, the polycrystalline Si film 10 covers the side wall of an opening section on the base side by overcross, and can be extended onto an Si3N4 film 4. The Si3N4 film 4 is etched through hot phosphoric acid treatment, and an SiO2 film 3 is etched by a hydrofluoric acid group solution. The polycrystalline Si film 10 is oxidized partially to insulate and isolate the base side and the collector side, and boron is implanted and diffused to the polycrystalline Si film 10 to shape a base leading- out electrode 13 and an external base region 14. Since these shapes can be determined approximately uniquely according to the growth conditions of the Si film, control is facilitated, thus improving the precision of a pattern.

Title: Method for inspecting fusion joint of plastic pipe
Inventor: MIHARA KEIJI
IPC: G01N29/11
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To realize a highly accurate reliable inspection, which can not be expected through visual view inspection, by finding a reference echo scope capable of discriminating an echo on the inner surface by ultrasonic flaw detection method and then subjecting a fusion joint to ultrasonic flaw detection under identical conditions. SOLUTION: Flaw detecting conditions, especially acoustic frequency, discriminable an echo with sufficiently high sensitivity on the inner face 111 at a plastic pipe part 11 are set by reflection pulse method employing a vertical probe 3. It can be set easily by varying the frequency of an ultrasonic flaw detector continuously and grasping the frequency when an echo e becomes large sufficiently at a time t0 =2T/C, where T is the thickness of the plastic pipe and C is the sound velocity in a plastic medium. Ultrasonic flaw detection is then performed under conditions being set while moving the vertical probe 3 on the outer surface of a fusion joint 4 and an echo scope is displayed. If an echo is present in the echo scope at a time t=2T/C, such a judgement is made that a defect exists at a joint directly under that flaw detection face.
