Inventor: HATTA TATSUO
IPC: H01S5/00
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To increase a light output emitted from a laser diode module, and to make the whole constitution of the laser diode module downsized and light- weighted.

Title: Rotary head assembly for magnetic recording and reproducing device
Inventor: HONDA KATSUHIKO
IPC: G11B5/52
Filed: 1985-09-02
Abstract: PURPOSE:To obtain a rotary head assembly with high turning accuracy by making the position where the moment of the radial load of two radial bearings is zero nearly coincident with the height of the rotary head. CONSTITUTION:The height of the magnetic recording/reproducing head is made nearly coincident with a position where the moment of the radial load of radial bearings is zero. Let the resultant force of a pressure distribution fa be Fa and the resultant force of a pressure distribution fb be Fb, the overturning (turning) moment due to external disturbance be M, then the relation of M=Fa s+Fb b is established. In order to make the position 0 where the radial load moment is 0 unchanged,the relation of Fa/Fb=b/a is established. In making the radial bearing widths A, B equal, a=b is obtained from the relation of A=B and the point 0 is a midpoint of the bearing span (a+b) of the radial bearings 5, 6. In making the point 0 where the radial load moment is 0 coincident with the height of the head, the head 1 is turned with a state of the least vibration to an external disturbance (overturning moment).

Title: Transmission device
Inventor: YAGISAWA TOSHIHIRO
IPC: H04N19/00
Filed: 1988-08-05
Abstract: PURPOSE:To improve reliability, to reduce cost and to lighten and miniaturize a device by providing a band compression means for a coder and providing a recording and reproducing means which records and reproduces a compression signal by means of the coder. CONSTITUTION:The coder 42 has the band compression means 56, and the recording and reproducing means 44 which records and reproduces the compression signal by the coder 42 is provided. Namely, the recording and reproducing means 44 records the compression signal by the coder 42 and therefore the recording and reproducing means 44 does not need to execute a compression processing by itself. The band is eliminated from being expanded in a non- compressed state in an input level for the recording and reproducing means 44. Thus, a processing related on compression and expansion is simplified and constitution is simplified and miniaturized.

Title: Operation circuit of pilot control valve
Inventor: ISHIYAMA HIROSHI
IPC: F15B11/00
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To relieve shocks at times of a stop, a reverse operation, and a start using only general purpose parts by connecting the output port of an opening and closing valve to an oil tank instead of closing an opening when the spool of a pilot control valve passes a neutral point. SOLUTION: When the lever H of an operation valve 6 is turned to the left side at a start time, pressure oil is supplied to a port 2b via the check valve of a flow control valve 3b. While the pressure oil also supplied to the port 8b of a directional control valve 7 from a pipeline 5a, and a pipeline 10a and a pipeline 24 a are connected so that the pressure oil of a pipeline 4b flows to an opening and closing valve 23. The opening and closing valve 23 is in a conductive state at first, but is shut off when the spool of a pilot control valve 1 moves a little. The spool of the control valve 1 starts to move rapidly in the early stage of the start time, but the pressure oil is shut off with movement so that the pressure oil of the pipeline 4b returns to an oil tank 11 from the operation valve 6 passing through the throttle valve of a flow control valve 3a. Thereby, the moving speed of the spool of the control valve 1 is reduced, and the oil volume flowing into an actuator is reduced so as not to give any shock to an operator.

Title: Device for automatically adjusting azimuth of reproducing head
Inventor: MINAMISHIMA MAMORU
IPC: G11B5/584
Filed: 1982-11-08
Abstract: PURPOSE:To simplify the circuit constitution and reduce the cost of the titled device, by generating an inversion signal which inverts a signal to high level and low level in response to the advance and delay of the signal phase and adding the inversion signal to an azimuth adjusting motor through a switching circuit. CONSTITUTION:When the azimuth of a reproducing head 1 is not under an appropriate condition and the phase of one phase comparison signal advances than that of the other phase comparison signal, the level of an inversion signal at the output point O1 of a phase comparison circuit 8 becomes high level Va by a high-level signal from the output terminal Q1 of a flip-flop circuit FF1. When the level becomes high, a dead zone setting circuit 15 outputs a high-level signal and closes the analog switches SW1 and SW2 of a switching circuit 16. In response to the closing, the high level Vb of the inversion signal is inputted into the switching circuit 16 and added to an azimuth adjusting motor and the azimuth of the reproducing head 1 is adjusted. When such an arrangement is made, the circuit constitution can be simplified and the cost can be reduced.

IPC: F21S4/00
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To increase the light flux of a fluorescent lamp in a low temperature range. SOLUTION: This luminaire is equipped with a coldest-point heating member 20 making substantially intimate contact with a tube-wall outer surface portion in the proximity of the coldest point in a lighted fluorescent lamp 30 and with a tube-wall outer surface portion higher in temperature than the coldest point to heat the tube-wall outer surface portion in the proximity of the coldest point by heat conduction. The axial length of the coldest-point heating member 20 is selected so that it can make substantially close contact with the tube-wall outer surface portion in the proximity of the coldest point (an outer surface portion of a glass tube 31 at an end part of the fluorescent lamp 30) and with the tube-wall outer surface portion higher in temperature than the coldest point (an outer surface portion of the glass tube in the proximity of a filament). Therefore, the coldest-point heating member 20 conducts the heat of the tube-wall outer surface portion higher in temperature than the coldest point to the tube-wall outer surface portion in the proximity of the coldest point in the fluorescent lamp 30 to heat it up, thus raising the temperature of the coldest point in the fluorescent lamp 30 and increasing the light flux of the fluorescent lamp 30 in a low temperature range.

Title: Porous electrode base of fuel cell
Inventor: SUGIYAMA TOSHIHIRO
IPC: H01M8/02
Filed: 1984-09-18
Abstract: PURPOSE:To increase reservoir capacity of electrolyte and enable electrolyte supplied to the reservoir to permeate and replenish speedily throughout a matrix layer by communicating electrolyte reservoir with the peripheral area of a porous plate and forming a hydrophilic region facing a matrix layer. CONSTITUTION:Electrolyte supplied from the outside permeates from a electrolyte reservoir 8 into the hydrophilic region 12 throughout the peripheral area of an electrode base 5, and then replenished from the hydrophilic region 12 around a matrix layer 3. From there, electrolyte permeates throughout the layer 3 by capillary action. This rapid permeation and replenishment over all area of the matrix layer 3 enables a characteristic of a cell to recover speedily after supplying electrolyte. Functioning as a reservoir of hydrophilic region 12 formed around the electrode base causes effective reservoir capacity of electrolyte to increase largely.
