Title: Apparatus and manufacturing method of semiconductor laser
Inventor: SHIMIZU HIROICHI
IPC: H01L21/208
Filed: 1978-07-28
Abstract: PURPOSE: To effect the oscillation in the single spot form by making the light spread ing angle small through such construction that the active layer provided on the semiconductor substrate has the stripe form extruding at the central portion of the resonator and becomes bigger in depth with distance toward the radiation emitting ends.  
     CONSTITUTION: On a N-type GaAs substrate 1 developed is a liquid phase epitaxial growth to form a N-type Ga 1-x  Al x As layer 2, at the central portion of which another epitaxial growth is developed to form a P-type GaAs layer 3. In this arrangement, the layer 3 is extruded upwards in the stripe form at the central portion of the layer 2 acting as the resonator and becomes bigger in depth with distance toward the radiation emitting ends at both sides of the resonator. In order to obtain such arrangement, a carbon rod 10 is sunk at the central portion in a solution chamber 11 in the stripe form at the time of developing the layer 3. Provision of this rod 10 enables the layer 3 to be thin at the central portion and thick at the circumference portion in depth. Then, over all surface including the layer 3 formed are a P-type Ga 1-x  Al x As layer 4, P-type GaAs layer 5 and N-type Ga 1-y  Al y As layer 9 in multiple layer in turn. Finally, a P-side electrode 7 is applied on the layer 5 via the hole provided through the layer 9 and a N-side electrode 8 is applied on the bottom surface of the substrate 1.

Title: Magnetic head
Inventor: FUTAMOTO MASAAKI
IPC: G11B5/127
Filed: 1987-04-17
Abstract: PURPOSE:To improve efficiency of recording and reproduction by enclosing the circumference of the magnetic pole of a magnetic head to be used for magnetic recording and reproduction with a superconducting material of an oxide system. CONSTITUTION:The superconducting material 4 of the oxide system is disposed around the magnetic pole. Infiltration of magnetic fluxes into the superconducting material is prohibited by a Meissner effect when the superconducting material 4 is cooled down to the critical temp. thereof or below. The decreased leakage of the magnetic fluxes and the increased magnetic flux density in the front end part of the magnetic pole are then resulted. Direct contact of the magnetic pole with a medium leads to breakdown of the shape at the front end of the magnetic pole when the magnetic head comes into contact with the medium, but such problem does not arise if the magnetic pole is so constituted that the oxide superconducting material comes into preferential contact with the medium. The degree of the breakdown of the medium or the magnetic head when the medium is slid is generally more significant with a magnetic pole material and is less with an oxide material. Namely, the spread of the magnetic fluxes is prevented and the sliding resistance of the magnetic head is simultaneously improved by constituting the magnetic head as shown in the figure.

Title: Method and device for powder compressive compacting for evaluating compressive compacting characteristic of powder
Inventor: TOMIYASU HIROSHI
IPC: B30B11/02
Filed: 1990-04-10
Abstract: PURPOSE:To accurately evaluate powder compressive compacting characteristics by finding the distance between the tip part of an upper pounder and the tip part of a lower pounder corresponding to a desired void percentage of a powder compressive compact from the real specific gravity and weight of powder to be compacted which is charged in a mortar. CONSTITUTION:Before the compressive compacting, the sectional area of the compacting chamber 19 of the mortar 3, the real specific gravity and weight of the powder, and the void percentage of the compressive compact are inputted to a storage, arithmetic, and control unit 31, which calculates the volume of the compact corresponding to the void percentage and then the quantity of downward displacement of the upper pounder 1. Then the powder is changed in the compacting chamber 19 of the mortar 3 and a piston rod 8 is moved down by a pressure cylinder 7 to press down the upper pounder 1, thereby compressing and compacting the powder in the compacting chamber 19 of the mortar 3. At this time, while the displacement of the upper pounder 1 is measured by a displacement gauge (differential transformer 13), the compressive compacting is carried out. When the upper pounder 1 reaches the calculated quantity of displacement, the unit 31 switches a direction selector valve 26 to stop the supply of compressed air to the pressure cylinder 7, whose compressive force is measured by a strain gauge 9. This compressive force is used to evaluate the compressive compacting characteristics.

Title: Ejector device of electromotive injection molding machine
Inventor: OKADA NORIHITO
IPC: B29C45/40
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To provide an ejector device of an electromotive injection molding machine capable of well separating a molded product from an ejector pin without applying overload to an injection molding apparatus even if an ejector plate is struck against an advance limit like a hydraulic ejector apparatus. SOLUTION: A spring 31 is arranged on the output shaft of the ejector device of an electromotive injection molding machine as a buffering member capable of absorbing inertial force. The ejector plate reaching an advance limit by the movement of the output shaft for ejecting a molded product is reduced in its ejection force by the spring 31 and the difference with the inertial force of the molded product becomes large. Therefore, the separation of the molded product from the ejector pin can be made certain. Since the overload generated at a time of the collision with the advance limit is absorbed by the spring 31, the damage of the device or the mold caused by erroneous setting can be prevented.

Filed: 1989-04-12
Abstract: PURPOSE:To reduce a busy rate of an inter-station relay line by allowing an exchange receiving a conference connection service request to select a conference trunk of an exchange station accommodating most of conference participants with priority. CONSTITUTION:When a conference connection service is requested, destination information of a called party is received by an exchange. A central processing unit of the exchange decides the exchange accommodating most of conference participants from the received information. When the exchange is its own station, the idle conference trunk of its own station is checked to apply conference call processing. In the case of the exchange of the other station, a conference invitation request signal is sent from its own station to the other station. The central processing unit of the other station selects a conference trunk and when an idle trunk exists, a request acceptance enable signal is returned and when no idle trunk exists, the request acceptance disable signal is returned. In the case of the request acceptance enable, the destination information is sent succeedingly via a conference trunk to await the opening of the conference. In the case of absence of the idle trunk, the presence of the succeeding selection station is discriminated, and in the case of presence, the succeeding selection station is decided and in the case of absence, the busy processing is applied.
