Title: Combustion rate control device of gas cooker
Inventor: YOSHIMURA SADAO
IPC: F24C3/12
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To control the flames of a burner to a large heating power as occasion demands by operating an operation unit which executes an adjusting operation which hinders a standard heating power zone from moving to a large heating power zone and cancels the blocked state produced when the operation is blocked by the control operation. SOLUTION: An opening 91, which inserts a rear end locking piece 81 of a lever main body 8 is formed on the front wall surface of a bracket 41 where a stage 92, which is a stop area, is formed on the upper edge of this opening 91. The position of the operation lever at the time when the rear end locking part 81 comes in contact with the stage 92, forms the border between a standard heating power zone and the large heating zone. One more stage 93 is provided on the opening 91. Even when the operation lever is moved in the throttling direction rapidly, the rear end locking part 81 comes in contact with the stage 93 so as to prevent the generation of an accidental fire, thereby blocking the rapid movement to the faintest heating power position.  This construction does not allow the operation lever to be operated, if a careless operation is executed, from the standard heating power zone to the large heating power zone and enables the flames of the large heating power to spring out dramatically around the surrounding areas such as pans.

Title: Optical information recording material
Inventor: NOMURA SHIGERU
IPC: G11B7/2533
Filed: 1984-11-30
Abstract: PURPOSE:To obtain a recording material free of double refraction, having excellent formability and moisture resistance and capable of being used for a high- capacity recording type optical disk, by limiting the degree of conversion into acetale of a polyvinyl acetal resin to within a specified range. CONSTITUTION:The optical information-recording material is formed from a resin composition comprising a polyvinyl acetal having a degree of conversion into acetal of not lower than 60mol% and lower than 65mol%. The polyvinyl acetal resin is obtained by bringing polyvinyl alcohol into reaction with an aldehyde in the presence of an acidic catalyst, thereby converting polyvinyl alcohol into polyvinyl acetal. If the degree of conversion is low, hygroscopicity is high due to residual hydroxyl groups. To obtain such polyvinyl acetal, it is preferable that purity of polyvinyl alcohol used as a raw material is high. Therefore, it is preferable that when polyvinyl alcohol is obtained by saponifying polyvinyl acetate with an alkali, the content of residual acetyl groups is not more then 5mol%. If the content of the residual acetyl groups is high, the transmittance of the recording material is low.

Filed: 1988-10-12
Abstract: PURPOSE:To decrease number of multipliers and to save the quantity of the hardware by employing multi-circuits for circuits corresponding to sections representing the same characteristic in a tap coefficient series of a transversal filter and using multipliers. CONSTITUTION:A digital input signal from an input terminal 1 is shifted sequentially in a shift register 2 by using a clock signal corresponding to a delay time. After the signal is shifted to a prescribed position, the content of a stage corresponding to an area 9 in the shift register 2 is led to M sets of n-stage 2nd shift registers 10. The frequency of the 2nd clock signal is selected so that the shift operation and multiplication operation are executed within one delay time as to the signal of the all stages of all the 2nd shift registers 10, outputs for M times from the 2nd multiplier 6a and the output of the multiplier 6 are added by an adder 7 and the result of addition is outputted to an output terminal 8. The output is extracted from the output terminal 8 for each delay time, then the same output of the transversal filter as the case with a conventional filter is obtained.

Abstract: PROBLEM TO BE SOLVED: To reduce deterioration of narrow band-pass characteristics at a low cost and to facilitate adjustment by forming a high-temperature superconductor film on a surface facing the internal wall surface of a metal housing, where a dielectric substrate having a microstrip line resonator is installed. SOLUTION: This dielectric substrate 2, where microstrip resonators each composed of a ground conductor 3 and a strip conductor 4 of the high-temperature superconductor film are formed, is arranged in a normal conductor metal housing 1 so that the ground conductor surface 3 is grounded to the internal wall of the metal housing 1. A housing upper lid is grounded to the bottom surface of the dielectric substrate 5 in terms of high frequency, by electrically connecting the high-temperature conductor film 6 to the metal housing 1 at its periphery.  Thus, the top surface internal wall of the housing 1 facing a ground conductor part is covered with the high conductor film 6, so that a region of the internal wall of the housing 1 where the normal conductor occupies is only sidewall; and then deterioration of narrow band-pass characteristics is reduced, and height of the side wall of the housing is varied, to vary the coupling coefficient between the resonators, thereby facilitating the adjustment the passing band width.
