Title: Metal vapor electric-discharge lamp
Inventor: WATANABE KEIJI
IPC: H01J61/12
Filed: 1980-11-17
Abstract: PURPOSE:To adjust the generated surge voltage to a given value, and secure the start of a metal vapor electric-discharge lamp by charging the outer tube with a charging gas at below a given pressure, and installing zirconium bulk getters in the outer tube, and thereby making a starting heat responsive element to operate in an atmosphere of the charging gas. CONSTITUTION:A rare gas such as xenon is charged into an outer tube 7 of a high-pressure sodium lamp at a pressure of below 100 Torr. Zirconium bulk getters 27 and 28 are placed near an emission tube 1. When a bimetal 4 is heated and operateds with radiation heat produced by heating a bimetal heating filament 5 by use of current for cutting off the contact between contacts 22 and 23, surge voltage generated in a ballast is reduced. The getters 27 and 28 absorb impure gas developed within the outer tube 7 during the life of the lamp.

IPC: G03F7/207
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To expose patterns to be transferred on the optimum focal plane of a projection optical system in accordance with the types of the patterns without making the management, etc., of process programs more complicated. SOLUTION: A projection aligner is provided with an AF system 20 which detects the attitude of the surface of a wafer W against a projection optical system 18 by projecting a light beam upon the surface, a Z-stage 21 which adjusts the attitude of the wafer W based on the detecting value of the AF system 20 so that the surface of the wafer W may become coincident with the optimum focal plane of the optical system 18, a storage device 15A which stores the offset information on the inclination of the optimum focal plane of the optical system 18 by respectively correlating the information with a plurality of exposure conditions,  and a controller 15 which controls the attitude of the Z-stage 21 based on the offset information corresponding to the exposure condition when the wafer W is exposed of the plurality of exposure conditions and the detecting value of the AF system 20 by reading out the offset information from the storage device 15A.

Title: Method for protecting secretion of stored data and portable information processor
Inventor: WATANABE KAZUHIDE
IPC: G06F21/62
Filed: 1994-07-14
Abstract: PURPOSE:To attain highly developed secretion protection for internal data by a simple operation and to surely release the protection. CONSTITUTION:At the time of inputting finger print shape information from a finger print shape detecting sensor part 3, a finger print shape/recognition discrimination controller 22 registers the information in a RAM 23. At the time of starting this portable information processor, the controller 22 newly inputs finger print shape information from the sensor 3 and collates the inputted information with the finger print shape information registered in the RAM 23. When both the finger print shapes coincide with each other as the result of collation, a CPU 21 optionally executes the start or the like of data stored in the RAM 23, but when both the shapes are mutually different, protects the stored data so as not to receive any user's instruction to the stored data after detecting non-coincidence. Since a finger print is used as secretion protection discriminating information, highly developed secretion protection can be executed and its release can surely be executed.

Title: Bearing structure of high speed rotational shaft
Inventor: GOTO TSUTOMU
IPC: F16C27/00
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an abnormal vibration and noise by the twist motion of the rotational shaft by projecting an outside oil pressure surface for partitioning a damper clearance from the bearing outer periphery surface of a retainer in a ring shape and partitioning an escape space. SOLUTION: When the twist motion, by which the tip of a rotational shaft 8 is twisted while drawing an arc at the motion time, is generated, the bearing outer periphery surface 25 of a retainer 15 is inclined for the inner periphery surface 21 of a housing and the section of a damper clearance 16 partitioned between both surfaces becomes in a wedge shape.  As a pair of escape space 27 for expanding a clearance continued from the damper clearance 16 by projecting the outside oil pressure surface 26 for partitioning the damper clearance 16 on the bearing outer periphery surface 25 of the retainer 15 in a ring shape is a structure partitioned in the ring shape, even if the twist motion of the rotational shaft 8 is generated, the oil film of the oil film damping layer is cut on the end of the damper clearance 16 and it can be prevented that both ends of the bearing outer periphery surface 25 are contacted for the housing inner periphery surface 21. Consequently, even if the twist motion of the rotational shaft 8 is generated, it can be prevented that the abnormal vibration and noise are generated from the near place of a rolling bearing 9.

Title: Rice cooker
Inventor: MIYAKE KAZUYA
IPC: A47J27/00
Filed: 1993-06-30
Abstract: PURPOSE:To provide a rice cooker which is excellent in an external appearance property in the periphery of a vessel containing part and assembling workability, and always prevents rice from becoming dry and dew from dripping from the lower face of a cover body. CONSTITUTION:In the outside of an inner frame 2, an induction coil 8 for heating a vessel 4 is installed. In the course of warming, the induction coil 8 is subjected to 1 second electric conduction/12 seconds disconnection. Also, in the case the inside of the vessel 4 exceeds a warming temperature, the 1 second electric conduction is unnecessitated. A temperature of the lower face plate 14 of a cover is kept higher than the warming temperature by 1 deg.C, only in the case the vessel 4 is below the warming temperature. In such a way, warming by the induction coil 8 can be executed through the inner frame 2 having heat insulation resistance. Therefore, a heat insulating member becomes unnecessary, and the inner frame can be formed integrally. Also, in the course of warming, a temperature of the lower face plate 14 of the cover comes to always be fluctuated high or low against the warming temperature.

IPC: H01F21/06
Filed: 1983-09-05
Abstract: PURPOSE:To manufacture a coil with less number of turns under the stable condition by utilizing a good conductor for an adjusting member of a high frequency coil. CONSTITUTION:In a high frequency coil 11, a coil body 15 is formed and an adjusting member, 16 is provided within the hollow part of such coil body 15 in freely movable manner. In a high frequency coil 12, a coil body 18 is formed and an adjusting member 19 is provided within such coil body 18 in freely movable manner. In this case, the members 16, 19 are formed by good conductor and thereby loss of high frequency signal can be lowered. Particularly since the members 16, 19 are formed by good conductive material and insertion of such adjusting members reduces an inductance value, an inductance value can be set to the highest value on design in the case of coreless coil and a number of turns of coil can be set to a large number. Thereby, a coil with less number of turns can be manufactured under the more stable conditions.
