Patent JP-H102761-A (JP)
Title: Photoelectric encoder
Inventor: YAKU TORU
IPC: G01D5/38
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a photoelectric encoder which eventually achieves larger amplitude of an output signal by enabling more efficient utilization of the light supplied. SOLUTION: Diffused light DL passes through a first grating 14 of an index scale 13. At this point, light interference occurs right below a step by a step of a grating element 17. The light interference forms a dark area of a dark and light pattern. When light is reflected on a second grid 15 or passes through a third grating 16, grid elements 18 and 19 block the passage of the light. As a result, in a photodetector 12, an output signal with a (grating pitch P/2) cycle is obtained during the moving of a main scale 11. Thus, a moving distance of the main scale 11 can be measured, based on the output signal.

Title: Control of idle revolution speed of internal-combustion engine
Inventor: TAKAHASHI TOORU
IPC: F02D31/00
Filed: 1982-09-06
Abstract: PURPOSE:To permit control with the proper transient response by setting the upper and the lower limit values in the estimated value of the state variable and the integration value of the deviation of revolution which are the main information of the control input value of a dynamic model for controlling a number of variables and allowing said limit values to be held. CONSTITUTION:An integration operation gain block 14 calculates two control inputs, width PA of the control solenoid driving pulse of VCM for controlling the bypath air amount in idling, and ignition timing IT, from the integration value of the deviation SA between the aimed value Nr of the engine revolution speed and an actual value N, and the state variable x calculated in a state supervisor 13, and controls the idle revolution speed N of an internal-combustion engine. Said state variable x is obtained through estimation of the dynamic internal state of a control subject 12 from the transmission function matrix which is linearly approximated. The upper and the lower limit values are set in the integration value of the deviation of revolution and in the estimated value of state variable, and when the limit value is reached, holding is performed. Thus, overflow and underflow in calculation can be prevented, and the idle revolution speed can be controlled with the proper transient response.

A shift amount reception part 6 receives the desired parameter value, and a shift amount deciding part 7 decides the shift amount of each area from said parameter value by means of the table 5. These decided shift amounts are stored to the table 8. A pattern reception part 9 receives an original graph, and a variable graphic deciding part 10 decides whether the points related to the shift are existed within the same area or not. Then a parallel shift part 10 and an expansion/contraction processing part 12 are actuated if said points are set within the same area or in different areas respectively.

Title: Combustor
Inventor: TAKESHITA SHIRO
IPC: F23L1/00
Filed: 1990-06-13
Abstract: PURPOSE:To accomplish low NOx and low noise by providing on the downstream side of a burner a combustion chamber, heat exchanger, exhaust unit, water inlet for feeding water to the heat exchanger, hot water outlet for feeding hot water to terminals, connecting pipe which branches off from the water inlet and communicates with a straightening plate through a shut-off valve. CONSTITUTION:Flame temperatures fall by such temperature as to correspond to the latent heat of vaporization of water in the atomized form supplied through a straightening plate 11. The quantity of produced NOx depends on the flame reaction temperatures and the quantity of produced NOx decreases as said temperature fall, and hence the quantity of NOx can be reduced. Since the plate 11 made of porous material is provided in an air chamber 7 to effect straightening of flow, uniformization of distribution and noise absorption, secondary air fed to a flame unit 8 is stabilized and flames can be stabilized an fluctuation of pressure produced during combustion is absorbed, with the result that peak of resonance produced in a space such as the air chamber 7, combustion chamber 3, etc., and an exhaust unit 5 is restrained. Further, sounds emitted from a fan 1 also is absorbed, so that fan noise from the unit 5 can be reduced.

Title: Variable-output oil burner, and water heater or hot water supply type bath heater with same burner
Inventor: OTA HIROMI
IPC: F23D11/38
Filed: 1989-06-16
Abstract: PURPOSE:To reduce pressure variations in a kerosene return pipe and thereby obtain a burner capable of stable combustion, by adding a condenser in parallel to an output terminal of a control valve-driving circuit. CONSTITUTION:When the effective value of a driving current applied to a return flow rate control valve 4 is increased by a control valve-driving circuit 6, the opening of the valve 4 is enlarged, rendering a return flow rate QR greater and a spray quantity QN smaller. When the effective value of the driving current is reduced, on the other hand, the valve opening is reduced, and the spray quantity QN is increased. Thus, the spray quantity QN can be varied. with a condenser 7 added in parallel to an output terminal of the circuit 6, a waveform is obtained in which AC components superimposed on a DC signal are substantially smoothed. Therefore, pressure variations conventionally generated in a kerosene return pipe 9 by the driving of the return flow rate control valve 4 are reduced, so that kerosene can be sprayed stably.

Title: Vertical magnetization recorder
Inventor: YAMAMORI KAZUTAKE
IPC: G11B5/02
Filed: 1978-12-18
Abstract: PURPOSE:To increase the record sensitivity by securing the fixed amount for the distance of shift between the recording main magnetic pole and the tip face of the high-magnetic permeability component. CONSTITUTION:High-magnetic permeabilit component 4 with coil 3 wound is provided inside main magnetic pole 2 formed by the high-magnetic permeability thin film and with the tip part opposing to magnetic tape 1. Then the D/T ratio is selected to 1/3-1 between shift amount D between pole 2 and the tip face of component 4 and total thickness T of pole 2 and component 4. Thus relative magnetic field H0 which is to be the recording magnetic field to tape 1 becomes maximum. As a result, the sensitivity can be increased for the vertical magnetic recording with a simple constitution using no exciting auxiliary magnetic pole or the like. If the tip part of component 4 is formed like the taper, the magnetic flux density can be increased to ensure the better recording.

Filed: 1995-06-21
Abstract: PURPOSE: To provide a pressing means for an optical fiber and the connecting method for the optical fiber which makes a stable optical connection with a high reflection attenuation quantity without using a refractive index matching agent which is unstable to temperature variation and suppresses the development, etc., of a crack even when the optical fiber is buckled. CONSTITUTION: When optical fibers 1 are fixed with fixation members 3a and 3b, the optical fibers 1 are buckled between an array member 5 and the fixation members 3a and 3b, so the opposite end surfaces of the optical fibers 1 are pressed against each other. Here, the optical fibers 1 have UV coating materials 1a removed only at parts arranged in through holes 5a and are still coated with the coating materials 1a at the buckled parts, so fracture due to the buckling is suppressed. The connection end surfaces of the respective optical fibers 1 are previously shaped, so the connection end surfaces of the respective optical fibers 1 are connected together in contact and the insertion loss and reflection attenuation quantity are both equal to or more than those of conventional technology.
