Abstract: PROBLEM TO BE SOLVED: To reliably and urgently shut off a circuit, while suppressing the explosion force of an explosive to low. SOLUTION: A bus bar 17 is connected between a battery post 3 and a stud bolt 10 to be connected with an electric power supply wire. An aperture 20 is formed in a housing 16 storing an explosive sealing part 15 and a fractured part 27 for the bus bar 17 is installed immediately in front of the housing 16. The fractured part 27 is made thin by forming a recessed part 28, and cut parts 30 are formed in both sides.  When abnormal incidents occur, electric current flows in a trigger wire 19 and an explosive in the explosive sealing part 15 is exploded and the explosion force is applied toward the aperture 20 of the housing 16 and the fractured part 27 immediate before the aperture 20 receives the explosion force in the front, so that the part where the recessed part 28 is formed as illustrated by the dotted line is at first ruptured and both ruptured fragments 38 are curved in the parts of the cut parts 30 as to be parted from each other. Consequently, an electric circuit is broken off.

Title: System for processing transfer of inter-module information
Inventor: KAI YASUSHI
IPC: G06F9/54
Filed: 1988-02-18
Abstract: PURPOSE:To share a common scheduler regardless of the addition/deletion and the change of modules by calling out these modules by using the address of an input/output information area including an input and output information parts as a calling parameter. CONSTITUTION:A scheduler 23 receives the information on the occurrence of an event from an event detecting part 1 and starts a prescribed module 24 for the event. Then the scheduler 23 sets the information decided by said event at an input information part 21 for delivery of an input/output information area 20. The module 24 refers to the information on the part 21 as a calling parameter for execution of the processing and sets the transfer information on the processing result at an output information part 22 to return it to the scheduler 23. The scheduler 24 refers to the next processing of the part 22 of the returned area 20 and starts another module 24 to be called next if designated. Then the contents of the part 22 are shifted to the part 21 and delivered to the relevant module. While an event waiting state is reset when the next processing is not designated.

IPC: C12N1/16
Filed: 1982-03-08
Abstract: PURPOSE:To suppress the occurrence of a variant of respiratory insufficiency produced during the cultivation of a yeast, by cultivating the yeast in a medium containing the extract of Dunaliella. CONSTITUTION:A yeast is cultivated in a medium containing the extract of Dunaliella. Dunaliella cultivated in a hypertonic salt medium, Dunaliella cultivated in a hypertonic magnesium sulfate medium, etc. may be cited as the Dunaliella used. The extract used is an extract obtained by extracting an alga of Dunaliella with a solvent. An aqueous solvent is preferable as the solvent, and an aqueous solvent containing a saccharide, salt, acid, base, etc. may be cited as the solvent. Since Dunaliella is basophilic and its cell is easily broken when it is immersed in pure water, or other hyptotonic solution, the extraction of the essence is preferably carried out by hot water extraction in a short time (about 3-5min) using an isotonic solution of glucose solution, mannitol solution, sorbitol solution, etc.

Title: Internal-combustion engine covering combustion chamber wall surface with porous heat insulating material
Inventor: KISHISHITA TAKAHARU
IPC: F02F3/12
Filed: 1984-02-29
Abstract: PURPOSE:To improve volumetric efficiency every so better, by covering a combustion chamber wall surface of a piston or the like with a porous heat insulating material. CONSTITUTION:A piston 4 is covered with a porous heat insulating member consisting of a porous heat insulating material 2 and a metallic film layer 3. This porous heat insulating material 2 is of ceramic having a minute hole of more than 80% in porosity. A combustion chamber wall surface of a head bottom, a liner, etc., is also covered in addition to the piston. With this constitution, heat in time of combustion will no longer escape owing to a heat insulating effect of the heat insulating layer and what is more, since heating for suction air is reducible, volumetric efficiency is thus improvable.

Abstract: PURPOSE:To simplify the angle adjustment at fitting by adopting different size for the butted face of holding members and allowing the difference of the sizes to bring the protruded part of the butted face into contact onto the reference face of a fixed member and fix it so as to eliminate the difference and variation of the magnetic gap angle. CONSTITUTION:The angle of a face mated to the butted faces 2a, 2b to the reference face A of the magnetic gap 3 is fixed to a prescribed angle theta to an angle of end faces 5e, 5f to the reference face A. Since the angle theta is decided with high accuracy in forming the supporting member 5 without variation, the shift of angle of the magnetic gap 3 to the reference face A and the variation in the shift are eliminated. Furthermore, a size B between the reference face A and the lower end of a core half 1', that is, a track lower end is decided definitely as the size being the sum of the height C of a projection 5d from the reference face A and a thickness D of the holding member 2'. Since the sizes C, D are decided with high accuracy in forming the supporting member 5 and the holding member 2', the size B, that is, the size of track position from the reference face A is decided to a prescribed value with high accuracy.

IPC: H04L7/08
Filed: 1995-02-24
Abstract: PURPOSE: To make a sync bit generation circuit used for a base station and a mobile station of a digital radio telephone system economical in configuration and small in size. CONSTITUTION: A flip-flop circuit(F/F circuit) 11 operates by the clock CK of 384kHz and the timing signal TM of a timing generation part 26, outputs a signal with the halved frequency of the clock to an F/F circuit 12. The F/F circuit 12 operates by the clock and outputs the level of the output signal of the F/F circuit 11 to an F/F circuit 13. On the other hand, the F/F circuit 13 outputs the signal of the halved frequency when the output signal of the F/F circuit 12 is inputted. A sync bit is outputted from an AND circuit 15 by the signal of the halved frequency and the timing signal. Thus, the sync bit generation circuit can be constituted by the inexpensive F/F circuit whose chip size is small.
