Title: Heater for indirectly heated cathode-ray tube
Inventor: MIYATA YOSHIHIKO
IPC: H01J29/04
Filed: 1985-12-13
Abstract: PURPOSE:To prevent crack of insulation layer due to thermal expansion difference between core lead and insulation layer by forming many recessed areas and extruded areas at the internal surface of insulation layer. CONSTITUTION:The internal surface of insulation layer 2 is formed with recessed portion and extruded portions. Therefore, even when the core lead 1 is in contact with the insulation layer 2 with a little deformation, a leakage current between heater and cathode can be reduced because of small contact area due to the recessed and extruded portions 3 at the internal surface of insulation layer 3 and a high insulation property can be maintained. When a gap 4 is provided between the core lead 1 and insulation layer 2, the core lead and insulation layer 2 are not influenced by distortion resulting from thermal expansion because thermal expansion of core lead 1 and insulation layer 2 is absorbed by the gap 4 and alumina crack and disconnection of core lead 1 can be prevented.

Title: Disk cartridge and driving mechanism for the disk cartridge
Inventor: OKITA MASAO
IPC: G11B23/00
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To fit a chucking hole and a positioning hole to a driving pin held by a spring member, by providing the positioning hole with a butting part which butts the driving pin of a disk cartridge-driving mechanism only in a rotating direction of a recording disk. SOLUTION: At an early stage with a 3.5-inch floppy disk 1 loaded on a turntable 8, a driving pin 10 is pressed to a hub 3 attracted by a chucking magnet 13 into a driving pin insertion hole 8(2) of the turntable 8 in spite of a repulsive force of a spring member 11. The driving pin 10 is located below the hub 3. When the turntable 8 rotates in a direction of an arrow A, the pin 10 reaches the neighborhood below a positioning hole 7 of the hub 3, and is fitted in the hole 7 because of the repulsive force of the spring member 11. The pin 10 consequently butts against an inner edge 7(1) at the side of a front end of the hole 7.  Thereafter, when the pin 10 butting the inner edge 7(1) of the hole 7 is strongly pressed, in reaction to the pressing, a spindle shaft 9 is pressed to a corner 6(1) constituted of two straight parts 6(2) and 6(3) of a chucking hole 6 thereby to move the disk 1. The disk is thus centered.

Title: Program changing method
Inventor: KAJIKAWA ISAO
IPC: G06F13/00
Filed: 1992-09-24
Abstract: PURPOSE:To shorten the time required for an operator to change a program by providing such a server system that transmits the data all at once when all transmission requests are received from a prescribed number of client systems. CONSTITUTION:The terminals 4-1-4-n have different processing speeds and the receiving timing s and therefore a server 300 receives the reception requests from the terminals 4-1-4-n in the different timings. Under such conditions, the server 300 is always busy if the change data are transmitted in accordance with the timings of the terminals 4-1-4-n. Therefore the next change data are not sent to the terminals 4-1-4-n before the transmission requests of the next change data are received from all terminals. When all change data are read, the end information is given to the terminals which are through with the reading of the change data.

Title: Manufacture of semiconductor laser
Inventor: YOSHIDA ICHIRO
IPC: H01S5/00
Filed: 1990-10-18
Abstract: PURPOSE:To make it possible to form a required strain multiple quantum well structure, reduce a threshold value, and increase its output power by using an organic metal gas phase synthetic process or a molecular line epitaxial process and changing cyclically the supply amount of In. CONSTITUTION:An AlGaInP optical waveguide layer 6 formed on an n-GaAs substrate 2 comprises AlGaInP light confinement layers 61 and 63, and an AlGaInP strain active layer 62. The layer 62 is manufactured and formed based on an organic metal vapor phase synthetic process where trimethylindium (TMI) or the like is used as a raw material gas. In this case, an epitaxial growth is made by changing only the flow rate of TMI gas, keeping a constant flow rate for the other raw material gases. On the other hand, when a molecular beam epitaxial process is used, two In raw material ejection cells are provided, one cell is adapted to keep an On state constantly while the other cell is ON/ OFF controlled, which makes it possible to change the raw material supply of IN. It is therefore, possible to obtain an active layer having a required strain multiple quantum well structure and manufacture a semiconductor laser which has a low threshold value and high output.

Title: Measuring apparatus for ion concentration
Inventor: OKI NAOTO
IPC: G01N27/416
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring apparatus whose measuring accuracy can be held easily by ejecting cleaning water which cleans a sample nozzle, a reagent nozzle and the like is into a dilution tank and measuring the ion concentration with an ion selective electrode. SOLUTION: Cleaning water which cleans the inside of a sample injection nozzle 1 is ejected, in about 500μl, to a dilution tank. The water is sucked to an integrated electrode 3 via a sipper syringe 5, and it is measured by a data processor 18 so as to be data-processed. Since the cleaning water is measured directly without being diluted, it is converted into the value of about 50 times when a sample is measured. When the sodium-ion measured value of the cleaning water is 10mmol/l and the cleaning water in a sample is 1 to 3%, a maximum error of 0.2mmol/l is generated in the measurement of a sample-diluted solution as compared with a case in which 1% of cleaning water is mixed uniformly.  When a sodium ion concentration to be alarm- displayed is set at 0.1mmol/l, a 'drop in the water quality of cleaning water' is displayed on a printer or a CRT when the sodium ion concentration in the cleaning water is computed as 10mmol/l. Thereby, the accuracy of a measuring apparatus can be controlled easily.

Title: High power factor switching power supply
Inventor: TSUJI HITOSHI
IPC: H02M3/155
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a power supply apparatus which can reduce switching loss, when a switching element is off. SOLUTION: A parallel circuit of a potential-up capacitor 11 and a resonance inductance element 12 is provided between an output side of a switch element 4 and a cathode side of a diode 7. With power feeding during the period, when the switch element 4 is on, a choke coil 6 can accumulate energy. When the switch element 4 is off, the choke coil 6 releases energy, through a smoothing capacitor 8, a diode 7 and a potential-up capacitor 11. After the release of energy, the potential-up capacitor 11 and the resonance inductance element 12 resonate with the released energy to increase the potential in the side of the switch element 4 of the potential-up capacitor 11.  When the switch element 4 is off, a potential in the output side of the switch element 4 becomes higher than that in the input side, a voltage applied across the input and output of the switch element 4 is lowered to drop the switching loss.

Filed: 1985-12-16
Abstract: PURPOSE:To simplify an intake air structure by connecting an intake passage on the lower course side of a throttle valve to a negative pressure tank through a connecting passage, while providing a control valve the opening of which is increased due to the small opening of said throttle valve, in said connecting passage. CONSTITUTION:A large capacity negative pressure tank 20 which absorbs excessive variation in intake negative pressure of a single cylinder, also serves as a balance passage. That is, a manually operated throttle valve 14 is provided in an intake passage 6 connected to the combustion chambers of cylinders, and the intake passage 6 on the lower course side of the throttle valve 14 is connected to the negative pressure tank 20 with a connecting passage 22, while a control valve 24 the opening of which is increased in the small opening area of the throttle valve 14, is provided in the connecting passage 22. Thereby, since the opening of the control valve 24 is increased during the low load operation of engine when the opening of the throttle valve is small, in particular, at the time of idling, the intake passages 61, 62 are connected to the negative pressure tank 20 at the lower course side of the throttle valve 14. Thereby, pressure variation in the intake passage 6 can be balanced, removing the instability of combustion like the conventional balance passage, while accumulating a large intake negative pressure in the negative pressure tank.
