Title: Musical sound synthesizer
Inventor: KUNIMOTO TOSHIFUMI
IPC: G10H7/00
Filed: 1991-04-26
Abstract: PURPOSE:To vary musical sound to be synthesized by a control signal supplied from the outside by adjusting the feedback ratio of the feedback path of an excitation meant corresponding to the control sagnal. CONSTITUTION:In a musical sound synthesizer in which a natural musical instrument is simulated, a signal is circulated between an excitation part 1 and a waveguide network 2, and a circulating signal is fetched as a musical sound signal. In such a case, nonlinear amplification by nonlinear circuits 104 and 106 is performed, and also, a negative feedback operation by the feedback ratio beta is performed. Therefore, hysteresis occurs in the input/output characteristic of the excitation part 1 i.e., the output change of a multiplier 108 against the input change of an adder 101, and the width of such hysteresis is increased as increasing the feedback ratio beta. For example, when the feedback ratio is increased by increasing a signal P corresponding to blowing pressure, a resonance frequency and the waveform of the input signal of the waveguide network 2 can be varied, and pitch height and a tone color can be varied.

Title: Hot water feeder
Inventor: MIYOSHI AYATERU
IPC: F24H1/18
Filed: 1987-04-21
Abstract: PURPOSE:To detect presence or absence of leaked water positively with a simple configuration at an initial stage by a method wherein a continuous time for a flow rate of fed water is measured. CONSTITUTION:In case of an accident of leakage of water, even if a user stops a water feeding after a desired feeding of water, a sensing of flow rate by a flow rate caused by a leaked water from a damaged part in a hot water storing tank 21 or a piping or a safety valve 27 is continuously performed, an overflow water in a bath tub due to a forgetting of stopping water of a user is continuously performed for its detection of flow rate. A comparing part 31 of a control part 30 compares, for example, a continuous time of sensing of a flow rate with a reference set value time, a discriminating part 32 may judge presence or absence of an abnormal condition such as a water leakage or overflow and in case that the abnormal condition is present, a transmittance part 33 is operated to operate the water stopping means or an informing means 34. In case of a longer period, even if the operation of the informing means 34 is stopped in advance, the control part 30 may compare data of a water flow rate meter 25 with a reference setting value and judging it so as to perform an automatic control of an opening or closing of an electromagnetic water stopping valve 24. Therefore, in case the hot water feeding unit shows an accident of water leakage or a forgetting of stopping water, tap water from a source of water supply is automatically shut, so that the hot water storing tank 21 is not applied with any a water pressure head and so a flow rate of leaked water can be instantly and rapidly decreased.

Title: Exposure lamp controller of copying machine
Inventor: SUENAMI KENICHI
IPC: G03B27/54
Filed: 1982-06-07
Abstract: PURPOSE:To ensure a linear change for the effective value of the voltage supplied to an exposure lamp to the set value, by providing a storing means for peak effective voltage value. CONSTITUTION:The effective value of voltage is obtained through a circuit 33 which rectifies the voltage of a power supply 31 of a copying machine. This effective value is stored to a capacitor with a specific timing by which the pulse is supplied from a pulse generating circuit 41. Thus the effective voltage value is stored in a peak value detecting circuit 34 for ahalf period. In order to vary the copy concentration, a comparator controls a driving circuit 38 which makes a bidirectional thyristor 39 on the basis of the value obtained from a subtraction performed by an arithmetic circuit 35 between the lamp voltage value Es indicated from outside 36 and the preceding storage value. The effective power value supplied to an exposure lamp 40 is restored to the original value after a half period despite the variation of the power supply voltage due to the conduction of a heater of a fixation device by varying the angle of conduction.

Title: Method and apparatus for detecting at least either the inclination or height of an optically multilayer object
Inventor: OSHIDA YOSHITADA
IPC: G01B11/02
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To accurately measure the inclination or height of an object having a laminate structure such as semiconductor wafers, irrespective of its structure or optical characteristics by setting the incident angle of an irradiating light to specified value or more. SOLUTION: A laser beam emitted from a semiconductor laser 1 is formed into a thin collimated beam to a collimate lens 11 and applied to an exposure area on the surface of a resist of a wafer through a mirror 13 at an incident angle of 85deg. or more. A reflected light is condensed on a light position detector 3' by a mirror 210 and condenser lens 20 to detect the condensed position thereof. If the exposure area inclines by α, the normal reflected light inclines 2α, and hence the condensed spot of the light position detector deviates 2α where (f) is focal distance of the condenser lens. Thus, control can be made so that the photoresist face on the wafer may align with the reticle pattern image face.

Title: Feeding method for purge gas for preventing occurrence of backfire at flare stack
Inventor: ITOU TAKUSEN
IPC: F23N5/24
Filed: 1983-06-01
Abstract: PURPOSE:To reduce an amount of purge gas to be supplied, by a method wherein it is previously detected that an exhaust gas amount, introduced to a gland flare, exceeds a treating colume, purge gas for preventing the occurrence of backfire is fed to a flare stack, and when an amount of exhausted gas is decreased over the treating volume, supply is stopped. CONSTITUTION:When a second ON-OFF valve 26 is opened and closed during an increase and decrease in the number of combustion steps of a burner, such opening and closing operation is detected by a limit switch 25, an ON-OFF valve 7 of a purge gas feed pipe 6 is operated, and purge gas for preventing the occurrence of backfire is fed to a flare stack 1. When the second ON-OFF valve 26 is closed, feed of purge gas is stopped. Before exhaust gas, equivalent to an amount, by which the exhaust gas exceeds the treating volume of the all-step burner treating volume of a gland flare 2, is introduced to the flare stack 1, the second ON-OFF valve 26 is already opened, and purge gas is previously supplied to the flare stack 1. Thus, the exhaust gas, remaining in the flare stack 1, is removed by means of purge gas, and this prevents the occurrence of backfire due to explosion.

Filed: 1994-05-13
Abstract: PURPOSE:To obtain a filament for artificial lawn pile fabric, composed mainly of a polyolefin- based synthetic resin, maintaining characteristics such as weather resistance and cold resistance, exhibiting a stiffness strong enough to recover from a g laid down state under pressure and having a visual appearance similar to a natural lawn when viewed from a distance. CONSTITUTION:A three-layer film composed of the core layer 3 prepared by blending 3 to 25 pts.wt., preferably 5 to 10 pts.wt. polycarbonate-based resin with 100 pts.wt. polyolefin-based synthetic resin and both the right and back surface layers 4 respectively prepared by impregnating 100 pts.wt. polyolefin-based synthetic resin with 0.1 to 2 pts.wt., preferably 0.2 to 0.5 pts.wt. decomposition type foaming agent (e.g. an azo-based, a nitroso-based or a hydrazide- based foaming agent) is formed by the melt co-extrusion method at a temperature beyond the decomposition temperature of the foaming agent. The resultant film is cut into a prescribed width and subsequently subjected to hot stretching by a factor of 3 to 10 times. A crimp treatment is applied to the obtained composite flat yarn 5, thus producing the objective filament for artificial lawn pile fabric. This filament can manifest a satisfactory recovering force by a stiffness of the core layer even when it is laid down by application of a pressure. Since an expanded resin layer constitutes each surface layer, white luster can be prevented by irregular reflection of light on the surface. An artificial lawn produced therefrom has, therefore, a visual appearance similar to a natural lawn.

IPC: F01N1/00
Filed: 1994-05-13
Abstract: PURPOSE:To provide a muffler which can achieve the reduction of manufacturing cost and the simplification of assembly work, and moreover obtain excellent silencing effect. CONSTITUTION:A muffler 30 is composed of an outer pipe 2, an inner pipe 4 and a silencing section 6. The outer pipe 2 is a so called stepped pipe, and composed of a large diameter section 23, small diameter sections 21 provided at both its ends and a tapered section 22, and can be obtained by applying a prescribed pipe diameter reducing method to a pipe to be reduced in dia. where a fixed tapered part is formed at the pipe ends and a plurality of grooves is provided axially. Since a plurality of grooves acts as so called a shrinkage margin, even if a pipe reduction rate is high, a pipe to be reduced in dia. is not damaged. Thus, since a difference in a diameter between the small and the large diameter part 21, 23 of the outer pipe 2 can be made considerably large, the space of the silencing section 6 surrounded by the inner and the outer pipe 4, 2 can be set up sufficiently wide, and sufficient silencing material can therefore be filled up therein.
