Title: 4-channel stereo reproducing device
Inventor: ONO KAIJI
IPC: H04S7/00
Filed: 1988-08-16
Abstract: PURPOSE:To allow a listener to feel as if speakers for each channel were located at an equal distance from the listening position by providing a means retarding an output of a middle channel by a prescribed time with respect to left/right channel outputs. CONSTITUTION:A listening position 107 has a distance (d) to a middle channel speaker 104 and a rear channel speaker and a distance l with left/right speakers 103, 105. In this case, the distance d' between the listening position and the left/right speakers has a difference 'd with the distance (d) and the output of the middle channel speaker reaches the listening position earlier by 't='d/v than the output of the left/right speakers, where V is the sound velocity. When the audio output of the middle channel speaker 104 is retarded by time t, the speaker 104 is felt to be moved imaginarily from the listening position to the distance d' and a natural presence is obtained, the output attenuation can be added in addition to the output delay.

Title: Catalyzer combuster
Inventor: MATSUMOTO TOSHINARI
IPC: F23K5/00
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a catalyzer combuster in which a gas flow rate is made large and an air flow rate is made small on igniting and further, the gas flow rate is turned to a rated condition and the air flow rate is made large in a catalyzer combustion to improve the ignition performance and the combustion performance by interlocking an ignition part and a pressure adjusting part. SOLUTION: When a user pushes down an ignition switch 40a, as an ignition part 40 and a pressure adjusting part 38 are interlocked, a control valve is further opened owing to displacement of a control lever 60 and fuel gas ejecting from a fuel tank is increased. Further, the efficiency of an air ejector 25 is decreased and suction air volume is relatively decreased. Hence, flame touches a catalyzer 23 for combustion and temperature abruptly rises. When the user releases the ignition switch 40a, the control lever 60 transfers to the original position, and the gas flow rate returns to the rated value. In this way, the gas flow rate is increased and the air flow rate is decreased at the time of iginition, and the gas flow is returned to the rated condition at the time of catalyzer combustion in order to increase the ignition performance and the combustion performance.

IPC: H01L21/822
Filed: 1986-08-29
Abstract: PURPOSE:To increase the capacitance per unit area and to reduce a leakage current by a method wherein, after a lower-part electrode metal has been formed on a substrate, an insulating film whose thickness is sufficiently thicker than a prescribed value is deposited on the lower-part electrode and a layer herring prescribed thickness is formed by etching, then an upper-part electrode metal can be formed on the layer. CONSTITUTION:An MIM-structured capacitor is composed of a substrate 1, a lower-part electrode metal 2, an insulating film 3 and an upper-part electrode metal 4. The insulating film 3 is formed by depositing an (SiN) film which is sufficiently thicker than do. The insulating film 3 is then etched so as to obtain a prescrided film thickness under a condition of isotropy or a little anisotropy. During this process, the initial film thickness to be deposited is to he thicker than do in order to avoid any locally thin part, and a film thickness which is thinner than do is finally obtained by etching. Through this constitution, it is possible to avoid a part whose film thickness is locally thin and which may cause the reduction in the breakdown voltage even though the film thickness is thinner than do.

Title: Film-thickness measuring method
Inventor: TAKEDA HISATAKA
IPC: G01B11/06
Filed: 1990-08-01
Abstract: PURPOSE:To make it possible to measure a film highly accurately regardless of the kind and the property of the film by containing the effect of the absorption of light in the interference waveforms of a sample to be measured and a reference sample having the same film quality as the sample to be measured, and offsetting the waviness when conversion functions are synthesized. CONSTITUTION:Incident light Li is imparted into a film 3 of a sample to be measured 1 and a film 4 of a reference sample 2 having the same material quality as that of the film 3. Interference waveforms 11 and 12 of an upper-surface reflected light Lf and rear-surface reflected light Lr which are detected after the reflection undergo Fourier transformation into individual converted functions 21 and 22. The shapes of the functions 21 and 22 have the waveforms of the high crests and waviness. The crests contain the interference information, and the waviness contains the information of light absorption. Then, the functions 21 and 22 are synthesized as the ratio pattern. The wavinesses of the functions 21 and 22 are offset with the synthesized function 30. False peaks do not appear in the function shape of a synthesized converted function 40 which is obtained by the Fourier transformation of the function 30. Peaks P and Q corresponding to the difference in light paths with respect to the samples 1 and 2 clearly appear without position deviation. A film-thickness detecting means 50 extracts the peaks P and Q, specifies the peak P corresponding to the sample 1 and computes the film thickness t1 of the sample 1 based on position coordinates xp.

Abstract: PURPOSE:To improve yield and to early accelerate the manufacture of a product by melting a fuse element by radiating it with a laser beam light or conducting a melting current if a timer setting time is required to be altered as a result that the timer setting time is actually measured after a die is sorted or a prod uct is inspected. CONSTITUTION:If the fact that variation in data reading speed due to a memory cell occurs due to an error in a processing step or the like at the time of mass production is discovered by a die sorting test, it is necessary to alter the timer setting time to a suitable value by altering the delay time of a delay amount controller 1 by operating a delay amount controller 1. In this case, when a fuse element F3 is, for example, melted to be turned OFF and a switch circuit 24 is closed, the output of a delay gate stage output terminal 644 of a delay circuit 64 is input to an inverter 65 to reduce the delay time. Thus, the setting time is shortened. In this instance, in order to close the switch circuit 24, fuse elements F1, F2 of the circuit 24 are melted to be turned OFF.
