Patent JP-S5562768-A (JP)
Title: Semiconductor device
Inventor: YAMADA MASAHIKO
IPC: H01L29/861
Filed: 1978-11-06
Abstract: PURPOSE: To prevent the damage at symmetry properties even when the relative locations of n emitters mounted on two main surfaces slip or even when cutting position, shifts, by dividing an n emitter into more than one portions, and by uniformly distributing and arranging the emitters.  
     CONSTITUTION: An n emitter 7 is partitioned, and equally shared and disposed onto a main surface. Since it is necessary to moderate the rate of the total area of the n emitter 7 occupying in one device to the total area of a p base 8 exposed on the main surface and the n mitter is approximately half the p base generally, the dimensions of the divided emitters 7 and spacing are equalized or the emitters are made larger. Thus, the device is not formed in asymmetry in a shape as compared with the conventional devices, and an SSS device, a pnpn switch element, etc. can be manufactured.

Title: Electromagnetic clutch
Inventor: TSUCHIDA NOBUNAO
IPC: F16D27/112
Filed: 1993-06-07
Abstract: PURPOSE:To provide stable frictional torque for connection of metallic surfaces to each other by way of preventing mixture and dispersion of abrasion powder on a metal friction surface by forming a recessed dent slightly smaller in width than width dimension of a friction material in the radial direction on a position facing the ring friction material on a rotor friction surface. CONSTITUTION:On a position facing a rotor friction material 19 on an amateur friction surface, a recessed dent 23 set slightly smaller in width than a rotor friction material surface 19a is formed equally balanced in the circumferential direction. Abrasion powder 22 of the friction material 19 produced by repetition of connection and disconnection is absorbed and stored in the recessed dent 23, and it is possible to prevent adhesion of the friction material abrasion powder 22 on the amateur plate friction surface 11a and formation of a shifted object. Additionally, as the recessed dent 23 does not open to rotor friction surfaces 8a, 8b, the friction material abrasion powder 22 absorbed and stored in the recessed dent 23 can be prevented from mixture and dispersion on the rotor friction surfaces 8a, 8b. Consequently, it is possible to secure stable frictional torque at a joint part of metallic surfaces to each other.

Title: Electronic musical instrument
Inventor: KOIKE TAKESHI
IPC: G10H1/46
Filed: 1994-05-27
Abstract: PURPOSE:To automatically execute an optimum demonstration playing by providing a sound volume characteristic control means which controls the sound volume characteristics so as to reduce the range of the change in sound volume at the time of executing an automatic playing for a demonstration. CONSTITUTION:A sound volume switch 21 is a switch to be used for a sound volume characteristics control means at the time of a demonstration. At the time of the demonstration, an indicator 24 which shows a 'normal condition' is normally turned on. However, when the switch 21 is depressed once, it becomes a 'larger condition' and an indicator 25 is turned on. This condition is selected when the environment is rather noisy. If the switch is depressed further, it becomes a 'smaller condition' and an indicator 23 is turned on. This condition is selected when the environment is rather quiet and the sound volume of the demonstration is to be limited so as not to exceed a prescribed value. By inputting adequate sound volume characteristics in accordance with the condition of an environment, the electronic musical instrument automatically controls the sound volume characteristics and therefore, any kind of music can be heard in their natural conditions and are controlled, so that the sound volume is controlled within a certain range.

Title: Enclosed nickel cadmium battery
Inventor: TSUKAMOTO HISASHI
IPC: H01M10/52
Filed: 1982-08-04
Abstract: PURPOSE:To prevent any damage to a battery by delaying the time when hydrogen is generated from the positive electrode when the battery is overdischarged by electrically connecting an electrode made of cadmium hydroxide or the like to the positive electrode before the battery is enclosed. CONSTITUTION:An alkaline aqueous solution such as aqueous caustic-potash solution is used as electrolyte. A positive electrode 1 containing nickel hydroxide or the like used as an active material and a negative electrode 2 containing cadmium and its hydroxide used as active materials are installed facing each other in cases 4 and 5, with a separator 3 interposed. After that, an electrode 6 which is used as a countermeasure for overdischarge and made of cadmium hydroxide or the like is electrically connected to the electrode 1, thereby constituting an enclosed nickel cadmium battery. As a result, the time when hydrogen is generated from the positive electrode 1 when the battery is overdischarged, can be delayed with a simple constitution. Consequently, the reliability and the safety of the battery can be enhanced by preventing any increase in the internal pressure.

Title: Magnetic recording medium
Inventor: TERANISHI HIDEAKI
IPC: G11B5/85
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium that guarantees the reproducibility of a high coercive force and is suited for mass production. SOLUTION: The magnetic recording medium is made of a non-magnetic substrate 2 where a non-magnetic metal layer 12 is formed on a non-magnetic substrate 11, and a non-magnetic metal ground layer 2 with a film thickness of 100nm consisting of Cr, a magnetic layer 3 with a film thickness of 20nm consisting of Co80at.%, Cr14at.%, Ta6at.% alloy, and amorphous carbon protection layer 4 with a film thickness of 12nm are laminated and formed on it by the successive sputter method, and a liquid lubricating agent is applied onto the protection layer 4 by 2nm, thus forming a lubrication layer 5. The half-value width of the diffraction peak of Co (110) of the magnetic layer is obtained by the X-ray diffraction measurement method and a crystal particle diameter (an average crystal size in the direction of film thickness) D110 calculated from the Scherrer equation is 70Å.  The medium has a coercive force 3,000Oe of Hc in circumferential direction, and a coercive force 2,000Oe or higher if its size is an average crystal size of 100Å or less. The prescription of the crystal particle diameter by the X-ray diffraction method is more reliable than the metering of the average particle diameter as compared with the prescription method by the TEM image, thus assuring the reproducibility of high coercive force and achieving a magnetic recording medium suited for mass production.
