Patent JP-S63289886-A (JP)
Title: Flash lamp control device
Inventor: ITO MASAYUKI
IPC: H01S3/092
Filed: 1987-05-21
Abstract: PURPOSE:To reduce the quantity of a stored charge and to make a capacitor small-sized by a method wherein an electric charge which is supplied from a second direct-current power supply for putting off a lamp is stored in a second charge-storage means formed by a resonance circuit composed of more than one coil and more than one capacitor. CONSTITUTION:A second charge-storage means 10 is a three-stage pulse formation circuit composed of three coils 10-a1-10-a3 and three capacitors 10-b1-10-b3. That is to say, an electric charge which has been supplied from an auxiliary power supply 9 is stored in the respective capacitors 10-b1-10-b3 of the pulse formation circuit 10; if a trigger pulse for putting off a lamp is supplied to a gate terminal 11G of an assistant thyristor 11, the stored charge flows to a main thyristor 7 as a square-wave electric current via the assistant thyristor 11. Accordingly, it is possible to shorten a duration from a turning-on operation of a second switching means to a putting-off operation of a flash lamp; it is not required to store a useless electric charge in the second charge- storage means 10. By this setup, the capacitors constituting the second charge- storage means can be made small.

Title: Magnetic disk device
Inventor: BABA HIROSHI
IPC: G11B5/596
Filed: 1986-05-28
Abstract: PURPOSE:To accurately position a magnetic head on a data track by controlling a driving part to correct the offset between the magnetic head and the data track by an offset correcting device based on the output of a reader. CONSTITUTION:If a magnetic head 7 is set off to a data track 14 by the influence of temperature or the like, this extent of offset coincides with the detected extent of off-track between the head 7 and a servo track 13. Then, the read circuit 31 of a first auxiliary position control part 25 reads out an off-set signal P stored in a storage part 29 and outputs it to an off-set correcting part 22. This correcting part 22 outputs an off-set correction signal 23 corresponding to the extent of off-set to a driving part 11. The driving part 11 controls a carriage 6 based on the signal 23 to move the head 7. Thus, the extent of the off-set between the head 7 and the track 14 is corrected.

Title: Fiber for energy transmission
Inventor: MORIMOTO SHOZO
IPC: G02B6/02
Filed: 1990-05-15
Abstract: PURPOSE:To enhance the cooling effect by a cooling medium by coating the outermost periphery of the fiber with a material having the thermal conductivity higher than the thermal conductivity of a material constituting the outer periphery of the fiber. CONSTITUTION:The fiber is constituted of a core 1 and a clad 2 and a coating layer 3 is provided on the outer periphery. The outer periphery of the coating resin 3 of this fiber is coated with a low melting metal 4 (for example, Bi-Pb-Sn- In alloy) having the high thermal conductivity. The outermost periphery of the fiber is coated with the material 4 having the high thermal conductivity in such a manner and, therefore, the cooling effect by the cooling medium is assisted by the fiber if the energy transmission line is cooled by the cooling medium. The high energy transmission is thus executed.

Title: Fuel injection control device
Inventor: ISHIDA KATSUMI
IPC: F02D41/10
Filed: 1989-05-17
Abstract: PURPOSE:To enhance the startability of an engine by forbidding asynchronous fuel injection until a synchronous signal is detected by a synchronous signal detecting means, after a power supply has been closed. CONSTITUTION:A RAM 56 is initialized by closing a power supply by means of an engine key. The valve opening TA of a throttle valve and the variation of TA are repeatedly obtained for each time interval t1 until a flag XIG reaches 1 by the processing of a synchronous signal interruption program being executed by a synchronous signal generated by the rotation of the engine. Since the flag XIG is 0 until a first synchronous signal is detected after the power supply has been closed, even if the variation  TA of the valve opening of the throttle valve exceeds a prescribed value, for instance, by stepping down an accelerator, increase of supply fuel is not carried out by calculating the asynchronous pulse width for driving a fuel injection valve 6. As a result, supply of surplus fuel before the starting of the engine can be prevented, and the startability of the engine can be enhanced.

Title: Brick masonry construction of blast furnace wall
Inventor: SETO SHIYOUZOU
IPC: F27D1/00
Filed: 1983-07-08
Abstract: PURPOSE:To decrease the damage of the bricks in a blast furnace owing to thermal expansion without requiring a material for absorbing the thermal expansion of the bricks in the stage of laying refractory bricks on the wall of the furnace by using mortar having large compressibility for the mortar for bricks and making the thickness thereof larger on the core side than on the shell side. CONSTITUTION:Refractory bricks 1 are laid up on the inside of a shell 4 of a blast furnace to build the furnace wall. Refractory mortar formed by adding org. fibers thereto to have 10-20% compressibility is used for the mortar to be used in this case. The thickness of the mortar between the bricks 1 is made larger with the mortar 2a of the bricks 1 on the core side than with the mortar 2b of the refractory bricks on the shell 4 side. The thermal expansion of the refractory bricks owing to a high temp. in the furnace is made absorbable by the mortar, so that the damage of the refractory bricks by thermal expansion is prevented without providing an allowance for thermal expansion such as ceramic fibers or the like used in the conventional method.

Title: Combustion controller
Inventor: NAGANUMA HISAO
IPC: F23N5/24
Filed: 1978-10-05
Abstract: PURPOSE: To invariably ensure stable combustion regardless of changes in air feed temperature and exhaust temperature during the combustion.  
     CONSTITUTION: With the ignition, a flame is sensed by a flame detecting circuit 32 and a burner motor 9 and a pump 18 are kept running for continuous combustion. At the same time, when the temperature in the combustion chamber 3 rises above a given level, a fan motor 5 is actuated to feed a hot air into the room. In this process, the feed air temperature and the exhaust temperature are detected with temperature detectors 14 and 16 and inputted to a differential amplifier 33 to detect the difference therebetween. The output is compared with the optimum temperature range. If it is determined to be out of the range, the output of a memory arithemetic device 34 is sent to one or both of a burner motor control circuit 28 and a pump control circuit 31 to bring it back into the normal range. Thus, one or both of the air volume and the fuel volume are changed to ensure combustion within the optimum combustion range.
