Title: Nitride semiconductor laser element
Inventor: SANO MASAHIKO
IPC: H01S5/042
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To improve the heat radiation property of a laser element and aim at continuous oscillation by inserting a laser chip where a positive electrode and a negative electrode are made on the same side into a support which has a recess whose inner face is metallized. SOLUTION: For a laser chip, an n-type nitride semiconductor layer 2, an active layer 3, and a p-type nitride semiconductor layer 4 are stacked on a substrate 1, and a negative electrode 10, on the surface of the n layer 2 exposed by etching, and a positive electrode 11, on the surface of the uppermost p layer 4, are made. A recess to insert a laser chip is made on the surface of the support 20, and the inner face of recess is metallized with a recess metallic film 21. A laser chip is inserted in face-up condition into the recess of the support 20, and the heat conducted to the board side of the laser chip is absorbed by the recess of the support. This makes the heat generated by the active layer easy to be conducted to the support, and improves the heat radiation property of the chip. Moreover, this can improve the reliability on a laser element.

Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To improve heat radiating performance by forming a high thermal conductive layer diffusing the generated heat by a heating element on a mounting substrate on the back surface of a hard cover to improve heat conductivity. SOLUTION: For a card-type circuit module housing the mounting substrate within a case 1 with the soft cover 10, the high thermal conductive layer 2 diffusing the generated heat by heat generating element 12 on the mounted substrate 11 is formed on the back face of the hard cover 10. In addition, in order to speedily transmit the generated heat from the heat generating element 12 to the high thermal conductive layer 2, a flexible heat conductor 4 is inserted between the heat generating element 12 and the hard cover 10. Consequently, on the back face 10 of the hard cover 10, the heat conductor is joined to the position corresponding to the heat generating element 12 to be a cooling target and the mounting substrate 11 is covered by the hard cover 10.  Thus the heat conductor 4 presses the heat sink surface of the heat generation element 12 with contacts while elasticaly deforming a little vertically to form a satisfactory thermal bus between the heat generating element 12 and the high thermal conductive layer 2 to improve heat radiating performance.

Title: Magnetic recording medium
Inventor: HOSOYA MANABU
IPC: G11B5/702
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium having better surface smoothness and electromagnetic conversion characteristics by specifying a difference between the pH of ferromagnetic powder incorporated into a magnetic film and the pH of the magnetic powder or non-magnetic powder incorporated in an intermediate layer to a prescribed value or below. SOLUTION: The magnetic recording medium 1 includes a base 2, the intermediate layer 3 disposed thereon, the magnetic layer 4 disposed on the layer 3 and a back coating layer 5 disposed on the rear surface of the base 2. The difference from the pH of the magnetic powder incorporated into the magnetic layer 4 of this magnetic recording medium is <=2, more preferably <=1. When the difference of the pH exceeds 2, a difference in thixotropy between the magnetic film 4 and the intermediate layer 3 increases and unequal coating and coating film defects are liable to arise. The magnetic powder having pH4 to 12 is usually used as the magnetic powder to be incorporated into the magnetic film 4 and the powder having pH of >=7 is preferable and the powder having 8 to 11 is more preferable in terms of the improvement of the corrosion resistance and oxidation resistance of the coating film.  The same holds true of the magnetic or non-magnetic powder to be incorporated into the intermediate layer 3.

Filed: 1987-07-16
Abstract: PURPOSE:To reduce internal resistance and improve discharge characteristic by press-attaching a wedge-shaped projection arranged on the back side of a cap to the upper part of a connecting part between cells. CONSTITUTION:A connecting part 8 between cells is formed by welding electrode lugs 7 of positive and negative plate clusters 5, 6 together, with a partition wall 4 of a case 2 interposed between them.

Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To make residual toner always retained inside a housing part in the middle of disassembling operation so as to prevent the toner from scattering outside and to improve operability in the case of the disassembling by forming the outside of a toner housing part side becoming a bottom surface into a planar state becoming a stable placing surface in the case a cartridge main body takes a posture that a toner housing part faces downward and an aperture faces upward. SOLUTION: The outside surface 2a of a toner hopper 2 on the opposite side of the aperture 6 is the flat planar state so as to be the stable placing surface. That is, the area of the surface 2a is made to be as large as possible, so that the surface 2a of the hopper 2 becomes the bottom surface in the case the aperture 6 faces upward and the cartridge main body 1 can be stably placed. The surface is formed to be the flat surface. Thus, the residual toner in the toner hopper 2 always retains inside the hopper in the middle of the disassembling operation, so that the toner is prevented from scattering outside. Since the toner cartridge is stably placed in the middle of operation, the operability in the case of disassembling constituting parts is improved.

Abstract: PURPOSE:To stably maintain pounding precision at the target pounding precision by providing a controlling part for operating an actuator which adjusts the opening of an outflow port of polished rice to the direction wherein the actual pounding precision of polished rice discharged from the outflow port thereof approaches the target pounding precision. CONSTITUTION:A polishing roll 3 provided to a polishing chamber is rotated and driven. Then unpolished rice sent into the polishing chamber is polished and this polished rice is discharged from the outflow port 7 of the polishing chamber. Pounding precision can be changed by adjusting the opening of the outflow port 7 for polished rice. Further a torque sensor 33 is interposed between the polishing roll 3 and a power source 5 for rotating and driving the roll 3 and detects transferred torque. Furthermore, a controlling part 40 compares the detected torque of the sensor 33 with a signal correspondent to the target pounding precision and operates an actuator 20. This actuator 20 adjusts the above-mentioned opening to the direction wherein actual pounding precision of polished rice discharged from the outflow port 7 approaches the target pounding precision. As a result, the pressure of the inside is directly measured regardless of fluctuation of voltage of a power source and dispersion of the characteristics of a motor. Thus, pounding precision is controlled stably and automatically.
