Title: Preparation of chemical-sensitive element
Inventor: MATSUZAWA YUKIO
IPC: H01L29/78
Filed: 1979-07-25
Abstract: PURPOSE: To obtain a chemical-sensitive element having an excellent drift and S/N by completely separating the front part of the element where the sensitive part is formed by selective etching from adjacent elements, before forming each region of an FET.  
     CONSTITUTION: Both surfaces a P-type silicon base 41 are oxidized to form SiO 2  layers. The layer is then photoetched to remove some portions of the layer covering scribed lines 45 and portions 46 to be removed. Shallow channels are formed on the scribed lines 45, and portions of the silicon base 41 corresponding to the portions 46 are completely removed. In this conditions, the front parts 43 of elements have been separated from each other, and their sides have been exposed. After portions of the SiO 2  layer where elements are formed and removed, regions of source, drain, channel stopper and the like are provided. Then the elements are separated from each other along the scribed lines 45, and finally the divided sides are coated with resin to obtain a chemical-sensitive element.

Title: Cathode body structure
Inventor: SANO KINJIRO
IPC: H01J1/22
Filed: 1988-04-14
Abstract: PURPOSE:To nearly unify the operating temperature of three substrate metals and suppress the change of the color tone during operation by making the resistance value of a lead wire connecting heating elements on both sides and heater terminals larger than the resistance value of a lead wire connecting the heating elements together. CONSTITUTION:The resistance value of a lead wire 5e connecting heating elements 5a and 5c on both sides among three heating elements 5a-5c arranged linearly and heater terminals is made larger than the resistance value of a lead wire 5d connecting the heating elements 5a-5c together. Since the resistance value of the lead wire 5e is increased, the resistance value of this ribbon portion is increased, the heat quantity of this portion is increased, the heat conduction loss can be reduced. The operating temperature of the center substrate metal can be made nearly equal to the operating temperature of the substrate metals on both sides, the change of the color tone can be suppressed.

Title: Method of measuring hole curve in drilling
Inventor: KATO JUNZO
IPC: E21B47/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of an adjacent hole in re-excavation by inserting the position detecting sensor for an excavating bit part under drilling into a drilled adjacent hole, and estimating the positional relation between the hole under drilling and the adjacent hole. SOLUTION: An excavating sound of an excavating bit 3 is generally differed according to the property of the ground or the presence of an obstruction, but it is preliminarily judged by a preceding examination, and the excavating sound is made to substantially constant excavating sound within the same or approximate ground quality. Thus, the stronger the excavating sound, the nearer the excavating bit 3, and it is detected by a receiving sensor 11 to estimate the positional relation of the excavating bit 3 with an adjacent hole 2, and the hole curve of an excavated hole 1 is measured. At that time, the hole curve can be precisely measured from the estimation result of the positional relation of the excavating bit 3 to each adjacent hole 2, and the hole curve under drilling can be relatively easily measured.  Thus, the re-excavation is early performed as occasion demands, whereby a bad effect on the adjacent hole 2 or the breakage thereof can be prevented, and an excessive excavating work can be also avoided to improve the workability.

IPC: H03D7/00
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To suppress the rate of an output signal of an oscillator leaked to an input signal transmission line at a weak input. SOLUTION: The signal amplitude oscillated from an oscillator 14 is varied with a level of an input signal from an input terminal 11 by using an output signal of an input level detector 16. Through the control as above, when the level of the input signal is small, the oscillated signal amplitude is decreased to suppress leakage of the signal from the oscillator 14 to an input signal transmission line. A mixer 13 multiplies the input signal amplified with an amplifier 12 by a signal from the oscillator and frequency components of the sum and the difference between two input signals are outputted from an output terminal 15.  In this case, a component of a DC output voltage is in existence, the oscillator 14 controls the oscillated signal amplitude and the leakage from a signal from the oscillator 14 to the input signal transmission line with respect to the input signal is suppressed, then change in a DC output voltage is suppressed to a small level.
