Title: Combustion apparatus
Inventor: KAWASAKI YOSHITAKA
IPC: F24C15/24
Filed: 1988-12-09
Abstract: PURPOSE:To permit the effective utilization of combustion heat by a method wherein a combustion chamber is provided with an exhaust gas collecting section constituting an inverted cup type exhaust gas collecting space at the upper part thereof and at least the front surface side wall of the section is constituted by a heat radiating body bored with a multitude of communicating holes to retrieve efficiently heat discharged together with exhaust gas and convert it into radiation heat. CONSTITUTION:Upon combustion, fuel is burnt in a combustion cylinder 2, the wall surface of the combustion cylinder is heated by a part of the combustion heat, the radiation heat of the combustion heat is discharged to the outside through a heat permeable member 4 while the radiation heat is radiated directly from the front surface and is reflected by a reflecting plate 3 from the rear surface of the title apparatus. Both of the radiation heats are used for heating the forward part of the apparatus and a space heating. The heat discharged together with exhaust gas is collected once into an exhaust gas collecting unit 5 and heat exchange is effected while high-temperature exhaust gas (arrow G) passes through the communicating holes 8' of a heat radiating body 8 whereby the exhaust gas is discharged as low-temperature exhaust gas (arrow G'). Heat, retrieved by the heat radiating body 8, is discharged from here by radiation again, however, the heat radiating body 8 is faced to the forward part of the apparatus and, therefore, all of the radiation heat can be used for the heating of the forward part and space heating whereby 50% or more of the combustion heat can be utilized effectively.

Title: Optical branching device
Inventor: SUGITA MASARU
IPC: G02B6/28
Filed: 1987-12-10
Abstract: PURPOSE:To assure the optical path where light is inputted from a waveguide to a waveguide through a half mirror even if electric power is not supplied so that the light can be transmitted to the ensuing station by disposing the half mirror between the waveguide and the waveguide and inputting the light reflected by the half mirror to the waveguide after amplifying the same. CONSTITUTION:The light outputted from a light emitting element 4 is reflected by the half mirror 31 and is inputted to the waveguide 2. The electric power outputted from power supply devices 5 of the respective stations B-D is stabilized and held to and at the specified voltage by a constant voltage power supply 32c and is supplied to a received light amplifier 32. The light emitting by the light emitting element 4 is no longer emitted if, for example, the electric power is assumed to fail to be supplied from the power supply device 5 by a certain reason while the light outputted from, for example, the waveguide 1 is amplified in said amplifier and is inputted to the waveguide 2. However, the optical path where the light from the waveguide 1 is inputted through the half mirror 31 to the waveguide 2 is assured and, therefore, the light is not amplified but can be transmitted to the ensuing station.

SOLUTION: In an apparatus, a plurality of timing signals at every identical angle of rotation are generated with reference to one rotation or a rotating body, and the angle of rotation of the rotating body is detected on the basis of the timing signals. Then, one timing signal out of the respective timing signals is changed, its change position is made to correspond to the zero point of the rotating body, a detection circuit 81 which detects the change position is provided, and the detection timing of the change position is detected as the position of the zero point. In this case, a plurality of slits are formed on the rotating body at identical intervals in the circumferential direction, and the formation of one slit out of the slits is omitted.  A signal output value is increased on the basis of beams of measuring light penetrating the slits when the beams of measuring light are blocked by the rotating body. The respective timing signals are formed in such a way that the signal output value is decreased when the beams of measuring light penetrate the slits. It is preferable that, when the output signal value is increased so as to reach a reference value, a zero-point detection signal is output.

Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To realize dynamic video of a character by storing shape data of an approximately circular shaped structural part so as to constitute the character and coordinate data for every content of action of the character. SOLUTION: The contents of the action of a character 5 for 60 frames per second are registered beforehand in a prescribed recording medium by preparing plural patterns and defining mutual positions of respective parts to constitute the character 5 as the coordinate data for the respective contents of action.

Filed: 1987-12-14
Abstract: PURPOSE:To shorten a processing time and to improve the performance of an instruction processing by making access to a main memory device only for one time in case of making access successively to the same address on the main memory device for plural times. CONSTITUTION:A detection circuit 9 detects a case where a vector load address store instruction makes access to the same address on the main memory device MS24. In case of a simple load store instruction, the address of operand data is decided by VAR representing the sum of a leading element address and an element interval VIR. Therefore, the access is recognized as the one to make access to the same address on the MS under a condition VIR=0. A request control circuit 10 changes the number of memory requests to be sent to a main memory control unit SCU23 by indication from the circuit 9. In other words, in case of making access to the same address on the MS, only one request is sent, not sending 64 requests successively.

Filed: 1990-11-21
Abstract: PURPOSE: To provide a substantially circular beam spot even in a peripheral part by preliminarily converging the phenomenon of electron beam vertically long before it is incident on a deflecting field by a quadrupole electrostatic lens changed according to the deflection. CONSTITUTION: A potential difference is caused between vertical bulkhead electrodes 15, 16 and horizontal bulkhead electrodes 12, 13 by the increase in deflection of electron beam to generate a quadrupole electrostatic lens electric field to each electron beam passing hole 17 between both the electrodes. In the quadrupole electrostatic lens, the electron beam incident in original circular form is made to a vertically long elliptic form. When a gradually increasing dynamic focusing voltage is consequently applied to a focusing lower electrode assembly 5 and a focusing upper electrode assembly 7 arranged on the electrodes 12, 13 according to the deflecting quantity, the action of the main electrostatic focusing lens is weakened according to the deflecting quantity to extend the focal distance of the electron beam.  Therefore, the focal track of the main electrostatic focusing lens is regularly formed near the screen of a cathode-ray tube. Thus, a circular beam spot can be provided also in the peripheral part of the screen, not to mention the screen central part.
