Title: Method for measuring concentration of acid or base
Inventor: EGUCHI YOSUKE
IPC: G01N31/22
Filed: 1986-12-01
Abstract: PURPOSE:To accurately measure the concentration of the acid or base in a liquid to be examined, by allowing an acid and/or a base having a pka value almost equal to that of a pH indicator to coexist in the liquid to be examined. CONSTITUTION:A liquid to be examined containing an acid or base is added to a liquid composition containing a pH indicator and an acid and/or a base having a pka value almost equal to that of the pH indicator and the change in absorbancy at that time is measured. By this method, a good calibration curve can be formed even with respect to the acid or base of relatively high concn. Therefore, the concentration of the acid or base in the liquid to be examined can be accurately measured.

Title: Coping at handrail corner and handrail structure
Inventor: YOSHIOKA TOSHIHIRO
IPC: E04F11/18
Filed: 1994-11-22
Abstract: PURPOSE: To prevent the shifting in the right-angled accuracy, by providing a joint at which otter copings are connected to a handrail corner coping and providing a little smaller protruded face than the joint, at the joint. CONSTITUTION: A L-shaped handrail corner coping 10 is formed by two coping bodies 11, 12 intersected at right angles with each other. And joints 11a, 11b are arranged in the coping bodies 11, 12. A little smaller protrusions 11b, 12b than the outer periphery of the joints 11a, 12a are provided at both joints 11a, 12a, to form stepped joints. Other copings 13, 14 are arranged to contact the protrusions 11b, 12b of the coping bodies 11, 12, from the right-angled direction. In this way, the subtle right angled shift between other copings 13, 14 and the handrail corner coping 10 becomes inconspicuous. And hence, the external appearance can be improved.

Title: Operating method for ink jet printing mechanism for reducing banding in concentrated dot type dither, and device therefor
Inventor: JOSEPH SHU
IPC: H04N1/60
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To broadly keep an external appearance of a concentrated dot type dither and make it possible to greatly reduce a banding phenomenon, by using different arrays in different components such that positions defined in dither arrays having different threshold value clusters are offset from one another. SOLUTION: In a half-toning treatment 62, a binary value is compared with a threshold value of a dither array on respective half-toning operations 80, 82, 84, 86. During the operation 86, a dispersed dot type dither method is used to obtain a binary black value KB. By using the dispersed type dot dither operation 86 in the black value K having a precise dissolution, it is possible to remarkably reduce undesired banding phenomenon without affecting a half- toning effect of the concentrated dot type dither method. Further, by carefully selecting a concentrated dot type dither array with respect to color components, it is possible to maintain concentrated dot type dither array and simultaneously reduce banding phenomenon.

Title: Production of highly corrosion-resistant stainless steel having metallic ti surface layer
Inventor: YAMANAKA KAZUO
IPC: C22C38/28
Filed: 1990-10-25
Abstract: PURPOSE:To produce a highly corrosion-resistant stainless steel having a metallic Ti surface layer by heat-treating a stainless steel having specified contents of Ti and Cr and with the C content of the impurities controlled in an extremely low oxygen potential atmosphere. CONSTITUTION:A stainless steel contg., by weight, 0.2-1.0% Ti and 9-18% Cr and with the C content of the impurities controlled to <=0.03% is heated at 600-1050 deg.C for 2min to 10hr in a vacuum at >=10<-7>Torr or in an extremely low oxygen potential atmosphere contg. >=99.999% of an inert gas (except N2). Consequently, the Ti in the stainless steel does not form its carbonitride or oxide, remains as a metal and is concentrated in the surface layer. As a result, a stainless steel highly resistant to corrosion at high temp. due to the nuclear fission product, capable of controlling the liberation of oxygen, hydrogen, etc., and having a metallic Ti surface layer is obtained.

Title: Motor temperature measuring apparatus
Inventor: ITO HIROKI
IPC: G01K1/02
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To measure the temperature of a rotator during the operation of a motor in real time with high accuracy. SOLUTION: A transmitter 18 converts voltage signals Sva, Svb corresponding to the temperature of magnet and shaft of a motor, measured by means of temperature sensors 12a, 12b, into frequency signals Sfa, Sfb which are then mixed to produce one frequency signal Sf. The transmitter 18 then transmits a signal Sfm subjected to FM modulation by the frequency signal Sf. A receiver 24 receives and demodulates the modulation signal Sfm to produce the frequency signal Sf which is then separated into two frequency signals Sfa, Sfb. The two frequency signals Sfa, Sfb are converted reversely into voltage signals Sva, Svb and outputted to a data logger 26.

Title: Drive circuit of motor
Inventor: OTANI KENJI
IPC: H02P6/28
Filed: 1988-11-16
Abstract: PURPOSE:To improve the controllability by setting the operating point of servo signal randomly and eliminating temperature dependence of the operating point. CONSTITUTION:When the positive input(+) side of a differential amplifier 30 is employed as a reference, output current IOUT flows from regions d4, d5 where a servo signal VIN is lower than a threshold voltage V4 and servo motion is achieved. d4 represents a stable region of the output current IOUT, d5 represents a transition region of the output current IOUT and d6 represents a release region of the output current IOUT. The operating point of the output current IOUT can be set randomly by varying the referential threshold voltages Vl, V4. When the emitter areas of transistors 4, 40 are regulated to provide identical temperature characteristics-2mV/ deg.C, formula I is obtained and temperature characteristics of the transistors 4, 40 are cancelled. By such arrangement, current I2 having no temperature coefficient can be obtained and temperature dependence of motor drive circuit can be cancelled.
