Title: Apparatus for cooling blades of gas turbine
Inventor: KOBAYASHI SHIGEYOSHI
IPC: F01D5/18
Filed: 1978-11-17
Abstract: PURPOSE: To attain uniform distribution of temperature over the surface of gas- turbine blades, by forming a plurality of radially extended cooling holes having the cross-sectional shape at a predetermined depth beneath the blade surface, and  changing the intervals between these cooling holes to suit distribution of heat transmitted from combustion gas.  
     CONSTITUTION: Cooling air 11 bled out from compressor is introduced into header 12 formed in rotor blade 10 and then into cooling holes 16 formed between outer metal plate 17 and structural core 14. Here, since the sectional configuration of these cooling holes is substantially the same, distribution of cooling air to the cooling holes 16 is uniform so that their cooling capacity is substantially equal to each other. As for cooling at the trailing edge of the blade, cooling air is issued to the outside from slit 15. In the above arrangement, distances S between adjacent cooling holes 16 are adjusted to suit distribution of heat transmitted from combustion gas. Thus, distribution of temperature over the surface of blades can be made uniform independently of the distribution of heat transmitted from combustion gas, since cooling capacity of cooling holes 16 is substantially equal.

Title: Waste disposal device
Inventor: HOSAKA MASATO
IPC: F23G5/50
Filed: 1990-05-29
Abstract: PURPOSE:To provide a waste disposal device which is of a simple constitution and dries and disposes of it without smoke and odor by providing a control means which stops a heating means in a waste receiving and storing chamber by the signal from a temperature sensor which is provided on a catalyst and then stops a blower after a certain time has passed. CONSTITUTION:It is possible to detect the end of drying of a waste 2 when a rise in the temperature of a catalyst 10 is detected by a temperature sensor 12. When the end of drying is detected by the signal from the temperature sensor 12, the oscillation of a magnetron 3 is stopped by a control section 15. Because of the heat capacity possessed by the waste 2 its temperature does not drop rapidly even if the oscillation of the magnetron 3 is stopped. Under this situation combustible gases are generated for a while from the waste 2. Now a blower 6 is operated for a certain time after stopping the oscillation of the magnetron 3 to supply the air for transportation to waste receiving and storing chamber 1. And, after combustible gases that are generated are all disposed of with the catalyst 10, if the operation of the blower 6 is stopped by the control section 15, the waste 2 is dried and disposed of without developing smoke and odor.

Title: Band correcting and amplifying circuit
Inventor: IKEBE HIROJI
IPC: G11B20/10
Filed: 1988-06-07
Abstract: PURPOSE:To stabilize the variance of an amplifier in a multitrack and to improve the S/N by inputting a signal whose frequency is higher than that of a signal which is reproduced by a magnetic head and verifying an amplification degree of the amplifier at that time. CONSTITUTION:In a state that an SW1 is closed to an input terminal side and an SW2 is opened, the title circuit is operated as a test mode for verifying an amplification degree of an amplifying element. In this state, from an input terminal 1, a sine wave signal of a frequency (fc) of (n) times of a signal frequency (fo) reproduced by a magnetic head is inputted to an amplifier 3. The signal which has been amplified by the amplifier 3 is rectified by a rectifier 4 and becomes a DC signal by an integrator, 5, and a DC level which has been varied in accordance with the amplification degree of the amplifier 3 is replaced with a digital signal by an A/D converter 6. Subsequently, the digital signal is encoded, and at every clock given to an input terminal 9, it is inputted to a D-flip-flop 6 and held. In such a way, said signal is amplified by a prescribed amplification degree irrespective of a variance by the frequency (fo) and can be outputted in a stable form, and also, the S/N can be improved.

Title: Error correcting coding and decoding system
Inventor: ONISHI MAKOTO
IPC: H03M13/23
Filed: 1992-06-02
Abstract: PURPOSE:To prevent the deterioration in the effective coding rate through the addition of a termination bit when a convolution code is employed in a communication system sending data in a burst way. CONSTITUTION:Some of first and last (K-1) sets (K is a restricted length) of codes in a code series outputted from a coder 50 are omitted and the remaining codes are transmitted, and the information such as the initial state of the coder 50, the termination bit, initial code point of time to be sent and a code burst length is decided simultaneously by a sender and a receiver. The omitted codes are estimated by using the information at decoding by a decoder 54. Thus, the error correction capability is higher for a convolution code with a long restricted length and a small coding rate and the reduction in the effective coding rate is large simultaneously. Thus, the code with a high error correction capability is used without decreasing the effective coding rate.

Title: Method for preventing formation of tin whisker
Inventor: KAWANAKA RIYUUSUKE
IPC: C25D5/10
Filed: 1982-08-12
Abstract: PURPOSE:To prevent effectively the formation of tin whiskers without losing the effect of tin plating, by subjecting a substrate metal to conventional tin plating and by forming a very thin lead layer on the plated metal. CONSTITUTION:A striking tin film 12 is formed on a substrate metal 13 such as brass by plating with a tin plating soln. A tin film 11 is formed on the film 12 by conventional tin plating, and a thin lead film 31 of >=0.05mum thickness is formed on the film 11. Since the tin plating and the thin lead film are separately prepared, the advantages of the tin plating are reserved, and the plating soln. requires simpler control than a plating soln. for solder plating. An expensive plating soln. such as a solder plating soln. is not used in this method, so this method is very effective as a method for preventing the formation of tin whiskers.

Title: Switching circuit
Inventor: NISHIDE TAKUYA
IPC: H03K5/1252
Filed: 1981-09-10
Abstract: PURPOSE:To prevent a malfunction of a control part due to chattering of a switch, and also to shorten an operating time of a remote-control device, by providing an integration circuit which integrates an output signal of the switch, and does not integrate an output signal of a receiver. CONSTITUTION:In case of a normal state, an FET1 does not conduct, an FET2 conducts, a point (a) is set to ''0''V, and a switch 3 is opened. Therefore, voltage of the lower end of a capacitor 22 is ''0''V, and voltage across it is a value V1 obtained by voltage-dividing the supply voltage Vcc by resistors 19, 20. When the switch 3 is operated in this state, its output voltage is integrated, and after that, is outputted to a transistor 9. Also, in case when pulselike voltage has been outputted from an output part A in a normal state, a time constant decided by values of the resistors 19, 20 and the capacitor 22 is selected in advance larger than duration of a pulse, therefore, the output voltage from the point (a) is superposed on said V1 and is outputted to the transistor 9. In this way, the output voltage from the output part A is not integrated, even if a pulse of short  duration is outputted, the circuit of the following stage and thereafter is operated exactly.
