Title: Frame for speaker
Inventor: ONO YUJI
IPC: H04R9/02
Filed: 1987-03-09
Abstract: PURPOSE:To strengthen the vibration-proof ability of a frame by containing magnesium, iron, lead, tin and cadmium as impurities in a frame alloy less than specified quantities respectively. CONSTITUTION:The frame for a speaker is made of the alloy consisting of a 22-40 weight % of aluminium, a 1.5-3.0 weight % of silicon, a 0.5-1.0 weight % of copper, a 0.2-0.4 weight % of manganese and the balance zinc. The impurities contained in the alloy are <= 0.05 weight % of magnesium, <=a 0.1 weight % of iron, <= a 0.003 weight % of lead and <= a 0.001 weight % of tin and cadmium. Normally, the Mg is remarkably effective for increasing the strength of the Zn, Al series alloy and the suppression of intergranular corrosion but the content is regulated as the impurities because it causes the rapid fall of vibration-proof.

Title: Magnetic bubble memory device
Inventor: SEGAWA MIKIO
IPC: G11C19/08
Filed: 1979-05-08
Abstract: PURPOSE: To improve reliability by inhibiting a memory from malfunctioning by stopping unneeded bubbles from passing by forming a pattern, giving strain to a substrate, on the substrate.  
     CONSTITUTION: Metallic pattern 9 with a great coefficient of thermal expansion such as Al is formed direct on a substrate, on which conductor pattern 6 of a magnetic bubble generator, permalloy pattern 7 and pattern 8 for propagation paths are formed via an insulating layer of SiO 2  or SiO. As for the chip formed in this way, feeding a current to conductor pattern 6 of the bubble generator may generate excessive bubble 15 in addition to normal bubble 14. Since Al pattern 9 differs greatly in coefficient of thermal expansion from the substrate, the substrate is given large strain. Therefore, even when excessive bubble 15 moves, it never gets out of the Al pattern. Consequently, the reliability improves with the malfunction of the memory prevented.

Title: Heater control device of air/fuel ratio sensor
Inventor: IDE KOJI
IPC: F02D41/14
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To provide the heater control device of an air/fuel ratio sensor for saving power by preventing unneeded preheating. SOLUTION: When the insertion of an ignition key into a key cylinder, the seating of a driver, the opening operation of a door, or the cancellation of door lock is detected, the ignition of an internal engine is predicted for starting preheating. For example, when the insertion of the ignition key into the key cylinder is detected (step 100), it is judged that the possibility of starting the internal engine is extremely high, and a target temperature Tc of a sensor temperature T is set to the highest T1 (step 102). Also, when the sealing of the driver is detected while no ignition key has been inserted (step 104), the target temperature Tc of the sensor temperature T is set to T2 that is lower than T1 (step 108).

Title: Optical information recording and reproducing device
Inventor: KOYAMA OSAMU
IPC: G11B11/10
Filed: 1985-03-22
Abstract: PURPOSE:To prevent the deterioration of C/N of a reproduction signal due to back talk as well as the unstable focusing and tracking servo control, by preventing the reflected light sent from a recording medium from returning to a laser. CONSTITUTION:The laser luminous flux delivered from a semiconductor laser 9 is turned into parallel luminous fluxes through a collimator lens system 10 and transmitted through a polarizer 11. Then the luminous flux whose polarizing surface is turned by pi/4 is made incident on a polarized beam splitter. The polarization axis of the splitter 13 is set coincident with the polarizing direction of the incident laser luminous flux. Then the polarized luminous flux is formed into a minute spot on a magnetic disk 15 via an objective lens system 14. The polarizing surface of the reflected light sent from the disk 15 is turned by an angle + or -thetak by the Kerr effect. This turned luminous flux is condenced to a photodetector 18 via a condenser lens 16 and a photodetector 17.

Title: Wire seal for waterproof connector
IPC: H01R13/52
Filed: 1992-03-13
Abstract: PURPOSE:To prevent the end of a connector from being detached by constituting a seal of a cylindrical section housing a cable, a stopper section annularly formed along a peripheral direction at the predetermined distance from one end of the cylindrical section, and a seal section annularly formed along a peripheral direction in a zone between the stopper and the other end of the cylindrical section. CONSTITUTION:This wire seal for a waterproof connector has a different constitution from a conventional wire seal in that a stopper section is positioned slightly inside the end of the seal, but the constitution remains unchanged in other respects. A wire seal 10a is monolithically formed with an elastic material such as rubber, and a stopper section 1 is separated from the end of a cylindrical section by a distance approximately equal to the width of the stopper section 1. More concretely, the wire seal 10a is constituted of the stopper section 1, a grip section 2, a seal section 3 and a projection 4. When a force to separate the seal 10 from a terminal is applied, the stopper section 1 is caused to come in contact with the end section 2a of the seal 10a, thereby preventing the terminal from being detached from the seal 10a.

Title: Encasing method for gas-filled shrink package body
Inventor: UEHARA HIDEMIKI
IPC: B65B17/00
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent pinholes from being formed on gas-filled shrink package bodies while preventing packaged matters from being decomposed by a method wherein the package bodies are encased while being wrapped up in polyolefin resin film. SOLUTION: The reason why pinholes are not formed on gas-filled shrink package bodies encased in a case seems to be attributable to the followings. Since polyolefin resin film is interposed between the gas filled shrink package bodies and the internal surface of the case, gas-barrier shrink films forming the external surface of the package bodies and the internal surface of the case do not directly rub each other. In the case where the gas-barrier shrink films stuck close to the edges and the corners of a tray are in contact with the internal surface of the case, pinholes are especially liable to be formed to those parts and therefore, wrapping up those parts in polyolefin resin film for preventing those parts from being directly in contact with the internal surface of the case is effective.

CONSTITUTION:The object quantity of freight to be delivered is predicted before receiving an order is closed, and vehicles corresponding thereto are arranged. In this case, a restriction condition, etc., for loading together freight to be delivered are converted to a knowledge base so that the number of vehicles becomes correct, by which the number of vehicles which has been calculated from the total capacity or the total weight of the freight is checked. Subsequently, based on the freight to be delivered which has been ordered and the object quantity, the delivery destination and its number of cases, the freight to be delivered by one car is determined by using the know-how of a car allotment schedule stored in the knowledge base. The delivery sequence of the determined delivery destination is solved by various algorithms which have been described and realized by a mathematical planning method such as minimization of the delivery cost. In such a way, it is possible to cope easily with a change of the restriction condition related to the allotment of cars which is apt to change, and also, a car allotment schedule whose calculation processing time is quick can be executed.
