Title: Chiming sound amplifier for electronic chiming circuit
Inventor: ITOYAMA HIROSHI
IPC: G04C21/12
Filed: 1978-07-11
Abstract: PURPOSE:To make it possible to always maintain constant the tone of the intermittently chiming signals, which are attenuated with a preset time constant, by using an amplifier which has its output voltage independent of the amplification of a transistor. CONSTITUTION:Sound frequency signals f1 are intermitted by chiming frequency signals f2 and are attenuated into chiming signals, which are fed to the base of a transistor TR Tr1. The primary winding of an output transformer is connected as a load resistor R1 between the emitter of the TR Tr1 and the collector of a TR Tr2. The emitter of the TR Tr1 and the collector of a TR Tr2. The emitter of the TR  Tr1 is connected through a resistor RE with a power source, and the TR Tr2 has its  emitter grounded to the earth and its base connected with the collector of the TR  Tr1. The output voltage of the amplifier thus constructed becomes EOUT = VO X  RL/RE (wherein VO stands for an input voltage) so that it become independent of  the amplification of the TRs Tr1 and Tr2. As a result, it is possible to generate the  chiming sounds of a preset tone irrespective of the influences due to the dispersion  and fluctuations in the amplitude of the transistors Tr1 and Tr2.

IPC: G11B7/24015
Filed: 1984-04-27
Abstract: PURPOSE:To prevent the deformation of a disk and the deterioration of a recording layer, and to realize the excellent durability by constituting a spacer provided on the inside and the outside peripheral parts of two disk substrates, of a porous material having gas permeability. CONSTITUTION:Between two discoid transparent disks 11, 11', spacers 13, 14 are inserted and held by its inside peripheral part and outside peripheral part. As for a material of the spacer, a porous plastic material having gas permeability similar to a disk material quality which passes air flow freely but does not pass dust in the air is selected. Accordingly, deformation by a pressure difference between the hollow part and the outside, which is generated when there is no gas permeability does not occur at all. Also, a dew condensation phenomenon of the hollow part when the outside temperature has dropped suddenly is not generated and the deterioration by a chemical variation caused by the dew condensation can be prevented. Therefore, the excellent durability can be realized.

Title: Gas cooking device
Inventor: YASUDA JUN
IPC: F24C1/00
Filed: 1989-04-04
Abstract: PURPOSE:To utilize the air flow of a cooling fan for using for the cooling of a hot air flow circulation fan to prevent the temperature increase of a top board by communicating an opening of the rear of an exhaust guide and an exhaust cylinder and another opening of the rear of a rectangular frame with each other. CONSTITUTION:A cooling fan 10 for cooling a hot air flow circulation fan 6 is set in the rear of the hot air flow circulation fan 6. The cooling fan 10 is allowed to draw-in air from the outside of a body to allow cold air to flow toward the hot air flow circulation fan 6. When cooking is executed in a heating chamber 5, heat is mainly transmitted in the heating chamber 5, an exhaust guide 8 and an exhaust cylinder 9 to also begin to raise the temperature of a top board 12. At this time, the cold air flow of the cooling fan 10 allowed to flow toward the hot air flow circulation fan 6 is allowed to flow upward through the exhaust guide 8. The cold air flow colliding against the bend part of the exhaust cylinder 9 is allowed to pass in an opening 13 of the exhaust cylinder 9 and collide against the top board 12 through another opening 14 of a rectangular frame 11. As the result, even if a cooking time is made long, the top board 12 is forced to be cooled by the cold air flow of the cooling fan 10 to control temperature rise. Accordingly, even if the number of cooking if large, deformation of the top board caused by heat is small to lengthen a life time of the top board 12.

IPC: G06F1/30
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To enable even a nonvolatile memory having a long writing time to store data and to prevent erasure of data in an emergency such as a power failure by writing the same data as those to be written into a RAM or a register into the nonvolatile memory every time the data are actually written into the said RAM or register. SOLUTION: When the data are stored in a RAM 5 or register 6 in a normal operation mode, an address signal which designates the RAM 5 or register 6 is inputted to an address control part 9b of a nonvolatile memory 9. Then an address is designated in response to every address signal. Thereby, an area which is corresponding to the RAM 5 or register 6 is allocated to the memory 9. If a power supply is cut under such conditions, the latest data are written into the memory 9 every time the data stored in the RAM 5 or register 6 are rewritten. Thus, the data stored in the RAM 5 or register 6 are saved into the memory 9.

Title: Voltage reference diode

IPC: H01L29/864
Filed: 1978-07-14
Abstract: PURPOSE: To reduce the noise draft by enveloping the periphery of P-N junction of a temperature compensation diode by a P-N junction having a smaller depth than the first-mentioned P-N junction.  
     CONSTITUTION: In the periphery of a P-N junction J 3  of a temperature compensating forward diode, provided is a P-N junction J 4  enveloping the junction J 3  and having a smaller depth than the latter. By so doing, the difference of impurity concentration between the junction J 3  in the bulk and the substrate is made smaller than that between the junction J 4  exposed to the substrate surface and the substrate, so that the forward voltage in the juction J 3  is smaller than the forward voltage of the junction J 4 . In consequence, the electric current can hardly flow in the surface region, and the electric current flows only through the PN junction J 3  in the bulk. It is therefore possible to obtain at a high yield a voltage reference diode which has a small drift and which is less liable to suffer unstable factors at the boundary between the junction and the protective film.

Abstract: PURPOSE:To raise the temperature of the exhaust gas led to a gas turbine in order to raise the gas turbine efficiency and attempt to raise the power generation efficiency of a gas turbine generator by providing a combustion assisting device to assist in the combustion of the exhaust gas in an exhaust gas pipe passage which transports the exhaust gas of a pressurized, fluidized bed boiler to the gas turbine of a gas turbine power generator. CONSTITUTION:Exhaust gas of relatively low temperature of about 830 deg.C that is formed by low temperature combustion goes through an exhaust gas pipe 12a for flow-in and is led to a combustion assisting device 17 after the dusts in the exhaust gas are caught in a dust collector 3. The exhaust gas of low temperature of about 830 deg.C that is led in this way to the combustion assisting device 17 burns with the combustion assisting combustion air from a combustion assisting air pipe 19 with combustion assisting fuel (natural gas, light oil, heavy oil, etc.) from a combustion assisting fuel pipe 18 at several hundred degrees over 1000 deg.C to become the exhaust gas of high temperature of about 1100 deg.C and is exhausted from a flow-out exhaust pipe 12b. This high temperature exhaust gas of about 1100 deg.C flows, therefore, into the gas turbine 11, and the turbine efficiency is raised and the power generation efficiency of the gas turbine power generator 10 is raised with the efficiency for the whole plant raised.
