Title: Jet engine designed to drive compressor by its steam turbine
Inventor: NEMOTO ISAMU
IPC: F02K3/00
Filed: 1978-08-04
Abstract: PURPOSE: To provide a jet engine designed to drive compressor by its steam turbine, in which heat absorbing tubes for heating water are provided along the inner wall of combustion chamber and jet nozzle of the jet engine, and these tubes are connected seccessively to steam turbine, cooler and pump, whereby it is enabled to increase output of the jet engine and thus to lower fuel consumption.  
     CONSTITUTION: Air with its pressure being increased by ram pressure is compressed further by compressor 1 and introduced into combustion chamber 3 under high pressure. In combustion chamber 3, fuel is injected from fuel injection nozzle 4 into compressed air for igniting and exploding the same, and thrust is obtained from kinetic energy of the jet stream of air ejected to the outside from jet nozzle 5. In driving the compressor 1, water compressed by pump 7 is supplied under pressure to heat absorbing tubes 6 formed along the inner wall of combustion chamber 3 and jet nozzle 5. In the tubes 6, water absorbs heat from combustion gas under isothermal and isobaric condition and is changed into over-heated steam. This over-heated steam is introduced into steam turbine 2 and expanded adiabatically, whereby turbine is turned at a high speed and compressor 1 is driven.

Title: Debugging system for logic type language
Inventor: HAGA HIROHIDE
IPC: G06F9/45
Filed: 1988-04-20
Abstract: PURPOSE:To cause output information to be as little as possible, and simultaneously, to cause a time difference detected with the place of a bug to be as small as possible by changing the execution sequence of debugging to that of an interpreter. CONSTITUTION:The execution sequence of a logic type programming language is changed from a 'depth priority (depth-first)' to a 'width priority (breadth- first)'. Namely, on the interpreter of a logic type language, under the control of the execution system of the logic type language realized by the logic type language, the execution of a logic type program is imitated, and the program to be originally executed in the depth-first is executed in the breadth-first. Consequently, without giving any change to the execution system main body of the logic type language, the program can be executed in the breadth-first. Thus, the difference in time up to a finding by the place of the bug can be made small, and the efficiency improvement of a debugging work can be executed.

IPC: A61P35/00
Filed: 1984-05-15
Abstract: PURPOSE:To suppress the discoloration of an etoposide solution, by dispersing an insoluble reducing agent in the etoposide solution, agitating the mixture, and removing the insoluble reducing agent by filtration. CONSTITUTION:An etoposide solution (e.g. solution of etoposide in ethanol, polyalkylene glycol, etc.) is added with 0.01-10wt%, preferably 0.05-0.5% insoluble reducing agent (e.g. sodium sulfite, sodium pyrosulfite, L-ascorbic acid, thiourea, etc.), and the additive is suspended in the solution by agitating at room temperature for >=10min. The obtained suspension is filtered to remove the insoluble reducing agent and obtain the etoposide solution having suppressed discoloration. In the case of using said solution for injection, the discoloration-suppressing effect can be further improved by sealing the solution together with an inert gas (e.g. N2, He, Ne, Ar, etc.) in an air-tight container such as ampule.

Abstract: PURPOSE:To obtain a smooth speech which contains no noise by editing the output of a reverse filter in each pitch cycle which is the output of a pitch extractor and leading the output to a synthesizing filter, and determining the characteristics of the reverse filter and synthesizing filter with the output of a spectrum analyzer. CONSTITUTION:The output of the reverse filter 8 is edited in each pitch cycle which is the output of the pitch extractor 6 and led to the synthesizing filter 10. The characteristics of the reverse filter 8 and composite filter 10 are determined with the output of the spectrum analyzer 7. Then the output of an editing device 9 is inputted to the synthesizing filter 10 (having the opposite characteristics from the reverse filter 8 because of the output of the spectrum analyzer 7) to obtain a speech signal wherein phoneme information is restored. Their input/output speed ratios need not be integers or reciprocals like 2 and 1/3 and may be 1.2 and 1.1, and the object of editing is a residue signal having no correlation, so there is no noise. Consequently, the smooth speech having no noise can be obtained.
