IPC: H01L21/822
Filed: 1988-04-19
Abstract: PURPOSE:To suppress the effect of a FET and to obtain a stable resistance value, by connecting a specified first diffused resistor and a specified second diffused resistor in parallel, commonly connecting one side of their terminals in common, and electrically isolating the other side of the terminals so that the second diffused resistor is not forward-biased with respect to the first diffused resistor. CONSTITUTION:A first diffused resistor comprising a first conductivity type semiconductor region 11 which is formed in a second conductivity type semiconductor region 12 in a first conductivity semiconductor region 13 is connected in parallel with a second diffused resistor comprising the second conductivity type semiconductor region 12. The terminals on one-side parts of said first and second diffused resistors are commonly connected. The terminals on the other sides of the first and second diffused resistors are electrically isolated so that the second diffused resistor is not forward- biased with respect to the first diffused resistor. For example, an insulating film 14 covers the surface of the P-type silicon substrate 13 on which the N<-> type well regions 12 and the P-type diffused region 11 are formed. Electrodes 21, 22 and 24 are provided at opening parts which are provided in the insulating film 14 so that said electrodes are used as the terminals of the diffused resistors. A buffer 15 is connected between the electrode 22 and the electrode 24.

Title: Ion source
Inventor: OKUDA SHOHEI
IPC: H01J37/08
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To provide an ion source of which plasma slit disc never causes insulation failure with a plasma chamber due to sputtering at an extraction electrode. SOLUTION: An endless ring-like slot part 14 that has an opening in the surface of an insulation spacer disc exposed to an extraction electrode side and surrounds an ion extraction hole 7a is formed. The slot part 14 is formed to have an almost L-shaped cross section perpendicular to its axial direction. A part of ion beams hits and sputters the extraction electrode, so that metal atoms such as C form a deposition 15 on a plasma slit disc 7, the insulation spacer disc 8 and a plasma chamber 2 which face to the extraction electrode. However, a shape part is formed inside the slot part 14 in the direction in which the metal atoms are scattered by forming the slot part 14 and thereby, the deposition 15 is produced by scattering it in an area from the plasma slit disc 7 to the plasma chamber 2, so that the insulation failure of the plasma slit disc 7 is prevented.

Title: Shaft seal device for vertical drainage pump
Inventor: CHIBA YOSHIAKI
IPC: F16J15/34
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To stabilize for a long time and to perform repeated air operation by providing an elastic member to release a seal surface comprising a seat ring and a seal ring. SOLUTION: A seal ring 3 is arranged above a seat ring 2 with a seal surface gap located therebetween. A press plate 8 is attached to the upper part of a seal case 5 to hold the seal ring 3 to press a coil spring 6. Namely, the coil spring 6 lifts up the seal case 5 and the seal ring 3 contained in a holder 4a. Thus, even when air operation is repeatedly effected for a long time, the press plate 8 and the holder 4a are lifted up through the reaction force of the coil spring 6. Since the seal surfaces of the seal rings 2 and 3 are brought into a non-contact state therebetween, there is no fear of abnormal wear occurring. Of course, there is also no feed to inject lubrication water from the outside.

Title: Cordless telephone set
Inventor: AZUMABAYASHI SHIGETSUNE
IPC: H04W88/02
Filed: 1991-04-26
Abstract: PURPOSE:To rewrite a charge/discharge equivalent even after the specification of an internal ROM of a microcomputer is decided and to allow the telephone set to cope with the design revision by storing the charge/discharge equivalent into a rewritable nonvolatile memory of a slave set. CONSTITUTION:When an ID code is stored in an electrical erasable P-ROM 16 at production of the telephone sets, the charge/discharge equivalent is also stored simultaneously. A microcomputer 12 discriminates a slave set operating state such as during talking, during charge, during call reception standby or the like and reads the charge/discharge equivalent corresponding to the state from the ROM 16. Then an arithmetic processing section 121 calculates a residual capacity of a battery based on the charge/discharge equivalent and displays it. Thus, even after the final stage of the product development, the charge/ discharge equivalent is revised and the telephone set copes easily with the design change.
