Title: Control system for serial printer
Inventor: NODA TOSHIKI
IPC: B41J29/38
Filed: 1978-04-18
Abstract: PURPOSE: To shorten the time for data transfer between an electronic computer and a printer by setting the initial value of a display counter controlling a busy control circuit by a column counter.  
     CONSTITUTION: Data D outputted from the central controller are parallel/series-converted by series/parallel converter 1 and then transferred to the printer. Further, data D are also sent to carriage-return decoder (CR decoder) at the same time and a CR code provided to data D is decoded. Although the output of CR decoder 3 is sent out to delay counter 4 and column counter 5, column counter 5 is made to count up by data other than the CR code and operates so that it will be initialized by the CR code; and the initial value of delay counter 4 is set by the count value of column counter 5 at that time.

Title: High voltage bushing
Inventor: MATSUURA KIYOSHI
IPC: H01B17/26
Filed: 1978-04-19
Abstract: PURPOSE: To simplify the structure of bushing insulator without making the length and thickness of bushing greater and to improve the withstand voltage over the surface by providing an insulating brim, the diameter of which is greater than that of flange, to the outside of the bushing insulator.  
     CONSTITUTION: An insulating brim 7, which forms the insulating barrier, is provided to the bushing insulator 1. The brim 7 is circular or polygonal and its outside diameter D is made greater than that D' of the frange 2. Also its location is determined such that the distance g between the brim and flange is made less down to the range in which the flange can be bolted. Thus the bushing can be made small- sized since the withstand voltage is improved by providing only an insulating brim to the bushing of the same dimension.

Title: Production of fiber-reinforced composite metallic material
Inventor: HASEGAWA JIYUN
IPC: C22C47/12
Filed: 1984-03-09
Abstract: PURPOSE:To prevent spring-back of a fiber molding and to obtain a fiber-reinforced composite metallic material which is easy to machine by using the fiber molding made by disposing reinforcing fibers on a lower pressure receiving plate coupled with a stress holding member and compressing the same with an upper pressure receiving plate. CONSTITUTION:A lower plunger 8 is placed in the bottom of the lower part 5 of a die and the bound material of a stress holding member 3 and a lower pressure receiving plate 21 is set thereof. Guide pins 9 are plunged onto the bound material and the die is set. Whiskers of silicon carbide, etc. 10 mixed with water are put each slightly into the die. An upper pressure receiving plate 11 is lowered by an upper plunger 7 and while the whiskers 10 are compressed, the plate 11 is forced into the top end part of the member 31 and is thus caulked, by which a fiber molding is formed. Such fiber molding is transferred into a molten metal forging installation where the molten base metal is brought into contact with said molding so as to penetrate therein. The molten metal is thereafter solidified and the precise and homogeneous fiber-reinforced composite material is thus obtd.

Title: Path changeover control system
Inventor: MIZUKURA TAKESHI
IPC: H04L12/437
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain the system in which both ends having a path fault inbetween are switched by allowing a communication equipment detecting the path fault to insert a fault signal to a main signal and to send the resulting signal and allowing a communication equipment not detecting the fault to select other path with a path changeover switch based on the signal. SOLUTION: When a path monitor section 8a of a station A detects a fault in a path from a station C to the station A, the section 8a uses a path fault detection output as a trigger to drive a path changeover section 9 of its own station so as to throw a path changeover switch from the position shown in solid lines into the position shown in dotted lines. Thus, the path is switched from a path via a station B into a path via a station D. Its own station fault signal FERP insert section 5a of its own station inserts a G1-byte to a path overhead POH of a main signal or inserts an FERP to a V5-byte and sends the resulting signal to the station C via the station B as a transmission signal SE.  On the other hand, when an FERP detection section 8-3a of the station C detects the FERP from the received signal, the changeover section 9 of its own station to switch the path from a path via the station B to a path via the station D.

Title: Linear type burner assembly
Inventor: UIRIAMU PII KOPIN
IPC: F23D14/62
Filed: 1992-02-03
Abstract: PURPOSE: To keep stable frame by adding such an amount as drop of oxygen level in a process air to the process air and introducing a combustion air into a mixing area for compensation, and increasing the oxygen level to at least a limited value for reinforced combustion characteristics of the mixture in the mixing area. CONSTITUTION: When the oxygen level in the process air is sufficient for keeping combustion of the mixture comprising the process air and gas, a burner assembly operates only on the mixture. However, when the level of inert gas is at a level sufficient for keeping a proper combustion of the mixture or above, or the oxygen level in the process air is at a scheduled limit value or below, the frame in the mixing area comes to be unstable. In that case, a control means 70 actuates a combustion air supply device 52 to supply a combustion air into the mixing area through openings 46 and 48 of a burner base 18, so that the composition of the mixture between air and gas supplied to the mixing area is reinforced, thus the frame generated in the mixing area is kept stable.

Title: Ion source
Inventor: TAGUCHI TADANORI
IPC: H01J37/08
Filed: 1985-03-11
Abstract: PURPOSE:To control consumption of ion source material by making the area of porous emitter material at the side contacting with the ion source material smaller than that of ion source material sump and the area at ion discharge side. CONSTITUTION:In order to control consumption of ion source material, supply of ion source material to the porous emitter material must be limited. It can be achieved by lowering the heating temperature but high current density can not be obtained. Consequently, it is necessary to reduce the contacting area between the porous emitter material and the ion source material. When reducing the area of porous emitter material at the ion source material supply port section and covering the remaining section with heat-resistant member, supply of ion source material to the porous emitter material is limited. As the heat- resistant material, same material with the porous emitter material, metallic material having high melting point such as Mo, Ta or heat-resistant ceramic can be employed. Preferably, the shape of the porous emitter material and the heat-resistant member is such that they will form a cylinder as a pair.

Abstract: PROBLEM TO BE SOLVED: To improve the throughput of the whole system by receiving a processing starting instruction from a central processor, writing the processing result in a response buffer through a response buffer mediation circuit and reading the processing result of a task from the response buffer. SOLUTION: Each of all the subprocessors SPU 4-1 to 4-n in idle states in which no processings are not executed performs a read access to an instruction buffer 2 through an instruction buffer mediation circuit 5, receives a processing starting instruction from a central processor 1 and writes the processing result in a response buffer 3 through a response buffer mediation circuit 6. The central processor 1 reads the processing result of a task from the response buffer 3 after the processor 1 writes the processing starting instruction in the instruction buffer 2. As a result, the improvement of the throughput of the whole system can be expected.
