Title: High cr steel tube excellent in workability
Inventor: ITAMI YOSHIAKI
IPC: C22C38/18
Filed: 1992-06-22
Abstract: PURPOSE:To obtain a steel tube hardly causing thickness reduction and breakage at the time of bending by actively increasing the Lankford value in a direction parallel to the rolling direction of a steel strip to be produced into an electric- resistance-welded tube and the Lankford value in a direction orthogonal to the rolling direction mentioned above up to specific values or above, respectively. CONSTITUTION:A strip of a steel containing 7.5-25wt.% Cr and having a metallic structure composed essentially of ferrite is continuously formed into a cylindrical shape by means of a roll forming machine and formed into a high Cr electric- resistance-welded tube by means of electric resistance welding. In this steel tube, in the stage of a steel strip, the Lankford value r0 in the direction parallel to the rolling direction of the steel strip and the Lankford value r90 in the direction orthogonal to the rolling direction are regulated to 1.2 or high and 1.5 or higher, respectively. When r0 and r90 are below the respective lower limits, workability sufficient to be used as automobile exhaust manifold, etc., cannot be obtained. Further, in the case where particularly strict workability is necessary, it is effective to regulate r0 and r90 to 1.5 or higher and 2.0 or higher, respectively.

Title: Optical head
Inventor: ANDOU HIDEO
IPC: G11B7/09
Filed: 1982-09-21
Abstract: PURPOSE:To provide high detection sensitivity to the out of focus near the focusing point by disposing a photodetector obliquely with respect to the locus that the condensing point of a detection optical system forms on account of the deviation in focusing. CONSTITUTION:The reflected light from the recording layer or reflection layer 10 of a recording medium passes through an objective lens 11 and is made into the light parallel with the optical axis 1 when the focus is matched. The parallel light are condensed on the blind zone 9 between two photodetection cells 3, 4 of a photodetector 5 inclined with respect to the optical axis 1 by a lens 12 of detection system, resulting in the decreased detection sensitivity. On the other hand, when the recording layer or reflection layer 10 approaches slightly to the lens 11 or parts therefrom, the light spot on the photodetector 5 spreads in width asymetrically to the right and left, resulting in the increased detection sensitivity. The high detection sensitivity for the slightly out of focus near the focusing point is thus obtd.

Title: Fuel injection unit for internal combustion engine
Inventor: YAMAMOTO YOSHIHISA
IPC: F02D41/38
Filed: 1980-11-21
Abstract: PURPOSE: To prevent delay in a timing of fuel injection by running the preliminary electric current which is slightly lower than the necessary actuating electric current beforehand on a magnetic valve deciding a timing of fuel injection.  
     CONSTITUTION: Fuel fed from the pressure source 3 is fed to a fuel chamber 23, while it reaches a port (a). When a force is added to a magnetic valve 15, the fuel pressure of pressure source 3 actuates on a chamber 20 to move a spool 13 toward right direction, so the pressure reaching the port (a) actuates a plunger 11 to lower direction to inject the fuel in the fuel chamber 23 from a nozzle 9. At this time the preliminary electric current which is slightly lower than the necessary actuating electric current runs through the magnetic valve 15 by a control circuit 5 before trying to add a force to the magnetic valve 15, so the magnetic valve 15 is added a force immediately after command of adding a force is given not to generate a delay in operation.

Abstract: PURPOSE:To obtain an inexpensive thermal recording head having excellent mass productivity by forming a large number of heating resistors and filmy switching elements connected in series with the heating resistors, which are  turned on by heat, on the same subtrate. CONSTITUTION:When a heating resistor 1a1 is to be driven, a switch 201 is turned to +E/2 side and a switch 211 is tured to -E/2 side, whereupon a voltage E is applied to a filmy switching element 191, and voltage to be applied to the other filmy switching elements 192 to 194 becomes E/2 or 0. In this case, when the voltage E meets the relationship E>Vr>E/2, only the filmy switching element 191 is turned on and a current flows in the heating resistor 1a1, whereby causing a heat-sensitive paper to be heated. By connecting the filmy switching element 19 with the heating resistor 1a in one to one basis in this way, the same matrixing drive as in the case of diode matrix can be attained.

Title: Hot water-supplying apparatus and water temperature-controlling method therefor
Inventor: ICHIKAWA HIROSHI
IPC: F24H1/10
Filed: 1990-06-21
Abstract: PURPOSE:To obtain hot water for which the fluctuation of water temperature is controlled by automatically regulating the mixing ratio of water to hot-water, by a method wherein a water-feeding pipe is joined to the side of an intake for a heat-exchanger through a temperature-measuring means for feed water, and a water-mixing means whereby the hot-water from the heat-exchanger and the water are mixed is joined by branching. CONSTITUTION:Temperature of hot-water from a heat-exchanger 13 is monitored by a temperature-measuring means 16 for the hot-water. That is, when the temperature of the hot-water rises to about 85 deg.C, a fuel-controlling device 20 actuates motion control in order to shut the supply of fuel gas for a gas burner 17, and the gas burner 17 is in the state of non-combustion. When the temperature of the hot-water falls to 70 deg.C or lower, the fuel gas is supplied to the gas burner 17 and the gas burner 17 is in the state of combustion again. When such a process is repeated, the temperature of the hot-water from the heat-exchanger 13 fluctuates within a definite range. However, the hot-water from the heat-exchanger 13 is led to a thermo-mixing valve 15, and the mixing ratio of the water to the hot-water is automatically regulated on the basis of the temperature of the hot-water, and hence the fluctuation of the water temperature is absorbed.

Filed: 1990-06-21
Abstract: PURPOSE:To shorten the checking time and to eliminate the operating mistakes with a nonvolatile memory EEPROM by checking all working addresses with a single key operation and displaying an error showing character if a defective area is detected. CONSTITUTION:When two specific keys, e.g., a CH display key and a CH storage key are pushed double on a key matrix, a microcomputer decides a test start command of an EEPROM 16 and displays a character 'TEST' on an image display device 17. Then the data O are written into all working addresses of the EEPROM 16. Then the microcomputer reads out the data and decides this data. If an area of the data 1 is detected even just in a single bit, a character 'ERROR' is displayed on the device 17. Then a test is through. Thus the quality of the EEPROM 16 is checked in a 'one-touch' operation.
