Title: Mercury metal halide lamp
Inventor: EMETSUTO EICHI UIRII
IPC: H01J61/20
Filed: 1987-06-26
Abstract: PURPOSE: To reduce the degradation of a mercury metal halide lamp by starting gas, mercury halogenide and single or a plurality of rare earth halogenides other than mercury iodide contained in an arc tube. CONSTITUTION: Iodine in a pool in the lower part of the conventional arc tube is substituted for rare earth bromide and silver bromide to be removed from a lamp and substituted for rare earth iodide and mercury bromide. The stability of the rare earth bromide is higher than that of the rare earth iodide, so that dissociation is few to reduce frosting on the arc tube wall. Since the frosting by the reaction of the rare earth on the wall is slight, a chemical loss is drastically reduced or removed so that the necessity of the rare earth in the pool is drastically reduced or eliminated. Since the frosting is small, the lamp temperature is made stationary and discoloration is reduced. Thus, the dimension and necessary Wattage of the conventional HMI lamp can be reduced and saved.

Title: Apparatus and method for driving flat linear pulse motor
Inventor: AOYAMA YUKIO
IPC: H02P7/00
Filed: 1994-06-16
Abstract: PURPOSE:To provide a flat linear pulse motor drive apparatus and a drive method by which a large drive torque can be generated by using a flat linear pulse motor which is identical to that in conventional cases. CONSTITUTION:An electrifying phase is adjusted by a regulator 200 so as to exceed pi/4. When the electrifying phase is adjusted to as to exceed pi/4 in this manner, the linearity of a generated torque with reference to the change in the electrifying phase is lowered. However, according to the magnitude of the electrifying phase, a current regulator 103 increases the effective value of an exciting current to prevent the linearity of the generated torque from lowering. When the electrifying phase is adjusted to exceed pi/4 and the effective value of the exciting current is increased in this manner, it is possible to generate a large drive torque.

IPC: G11C11/409
Filed: 1991-06-28
Abstract: PURPOSE:To provide a multi-bit output semiconductor memory having a high speed and low noise by dividing output circuits into two groups, and so switching the groups to levels of opposite directions. CONSTITUTION:At the time of reading access, an output circuit group 160 is driven to a high level side by a signal 195 from a predrive signal generator 190 before it outputs a read signal 151. On the other hand, an output circuit group 165 is driven to a low level side before it outputs a read signal 156. After a predetermined time, the circuit 160, 165 are driven by the signals 151, 156 by the deenergization of the signal 195, and read data are output to terminals 162, 167. Thus, the groups 160, 165 are always driven to levels of opposite directions, thereby largely reducing noises of a power source line and a ground line.

Filed: 1979-12-06
Abstract: PURPOSE:To protect the semiconductor element in the plastic molded type semiconductor device from contamination or mechanical strain and improve its reliability by providing a space between the semiconductor element and the sealing resin for the element. CONSTITUTION:The semiconductor device in which a semiconductor element 1 and a bonding wire 3 have been secured to one of leads 2 by bonding is placed in a cavity 10 in a mold 6 for transfer molding. Then from a nozzle 7 a high pressure gas is injected towards the semiconductor element 1. This causes the air pressure around the semicoductor element 1 to be higher than that near the wall surface of the cavity 10. Therefore, the resin 4 supplied through a runner 8 at this time never flows in towards the semiconductor element but flows out around its periphery, so that a resin sealing part having a space between the semiconductor element and the resin is formed. Said procedure permits a cheapr plastic molded semiconductor device having high efficiency and reliability to be obtained.

Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To ensure the anchoring of a back member into a recessed part formed on the rear face of a club head body through bringing both into tight contact with each other in a golf club such as an iron. SOLUTION: When anchoring a back member 9 into a recessed part 8 formed in the rear face 7 of a club head body 6, by plastically deforming the back member 9, the back member 9 is heated to set it in a high temperature state. This temperature is almost 750 deg.C, that is, a standard temperature at which the forging of a metal is almost completed in case the metal is titanium or a titanium alloy. Consequently, it is possible to plastically fabricate and fit the back member 9 under a high temperature state and thereby, decrease the deformation resistance of a metal material in the back member 9 to enhance its ductility.  Therefore, the front face 14 and the peripheral face 15 of the head body 6 can be fitted into the recessed part 8 by bringing the former into tight contact with the latter without a gap, so that it is achieved to strongly anchor the back member 9 into the recessed part 8 and improve the strength of the head itself and make a face 4 thin.

Title: Exhaust heat recovering device
Inventor: MASUGUCHI YOSHITSUGU
IPC: F24S90/00
Filed: 1983-08-30
Abstract: PURPOSE:To positively recover the exhaust heat of the boiler with high efficiency by connnecting a jacket provided in a tank to an exhaust heat recovering heat exchanger through a heat medium feed pipes and subjecting the heat medium to natural circulation between the jacket and the exhaust heat recovering heat exchanger. CONSTITUTION:Jackets 12 are perpendicularly provided around the inner and outer peripheries of the heat accumulating tank 1. Heat medium feed pipes 13 are connected to the upper and lower parts of the jackets 12. These feed pipes 13 are connected to an exhaust heat recovering heat exchanger 9 mounted in an exhaust part 8 of a boiler 7. Further, heat medium feed pipes 13 of the solar heat collector 6 are mounted on the jackets 12. Since the titled device is constructed as described above, the boiler 7 is heated, and when the temperature of the heat medium within the heat exchanger 9 mounted on the air exhaust part 8 becomes increased, the heat medium naturally circulates between the heat exchanger 9 and the jackets 12 through the feed pipes 13 by the difference in the specific gravity. In this case, the combustion quantity of the boiler 7 is proportional to the quantity of the circulation of the heat medium heated by the heat exchanger 9. Hence, the exhaust heat of the boiler 7 can be recovered efficiently and easily.
