Title: Multiplier
Inventor: TANAAMI SHIGEYUKI
IPC: H03B19/18
Filed: 1990-05-11
Abstract: PURPOSE:To short-circuit a 2nd order harmonic wave across a diode and to improve the conversion efficiency of a 4th order harmonic wave by providing a radial stub of 1/4 wavelength of the 2nd order harmonic wave and the 4th order harmonic wave and a microstrip line of 1/4 wavelength of the 2nd order harmonic wave. CONSTITUTION:An input signal whose frequency is fIN inputted from an input terminal 1 is sent through a microstrip line 3 and fed to diodes X1,X2. The diodes are alternately turned on/off depending on the polarity of the input signal and the signal sent to the slot line 9 is a full rectifier waveform of the input signal. A 4th order harmonic wave included in the full rectifier waveform is propagated through the slot line 9, is converted into a signal for the microstrip line 4, and outputted from an output terminal 2. On the other hand, since the signal is short-circuited by a radial stub 6 at the side of the input terminal 1, the 4th order harmonic wave does not appear at the input terminal 1. Moreover, the 2nd order harmonic wave is short-circuited by the microstrip line 8 and does not appear at the outside.

Abstract: PURPOSE:To make a transmission circuit and a reception circuit alternately and independently effective and to prevent degrading of sound quality of a transmission/reception sound signal by using a high frequency being or more that of the sound signal so as to intermit alternately the transmission circuit and the reception circuit. CONSTITUTION:An oscillator OSC is oscillated in a frequency being >= twice the sound frequency and a switch circuit SW2 provided to the transmission circuit and a switch circuit SW3 provided to the reception circuit are switched alternately into the conductive state and the interrupting state. When the circuit SW2 is conductive, a transmission signal from a microphone MC is transmitted to a hybrid circuit HYB, but since the circuit SW3 is interrupted, the transmission signal is not leaked to a speaker SP. While the SW3 is conductive since the circuit SW2 is interrupted, the reception signal incoming from a telephone line L is supplied to the speaker SP via the circuit HYB, an amplifier A2 and the circuit SW3 regardless of noise in a room. Then the reception state is standardized at a frequency being twice of the sound frequency.

Title: Electrode of constant potential electrolytic gas sensor
Inventor: NAKAMURA TAKAKI
IPC: G01N27/404
Filed: 1995-05-23
Abstract: PURPOSE: To output a warning at a tolerant concn. or less by supporting a catalyst composed of ultrafine particles of gold on a carrier composed of conductive material quality. CONSTITUTION: Pores 2 are provided on a stainless steel plate material 1 by etching processing and a compsn. 3 prepared by adding 2wt.% of carbon to a mixture of ultrafine particles of gold and a fluoroplastic suspension is pressed to the plate material 1 to fill the pores 2 and the whole is baked to form an electrode. A platinum black electrode is also formed in the same way by using a mixture of a platinum black powder and a fluoroplastic suspension. A gold vapor deposition electrode is formed by depositing gold 5 on a gas passing film 4. The electrode using ultrafine particles of gold as an electrode catalyst is used as the electrode of a gas sensor. When semiconductor producing gas is detected by using this gas sensor, the surface area of the electrode itself is large as compared with a conventional electrode and a three-phase field reacting with gas becomes large.  Therefore, an output power value is high and a good result is obtained and, since the interference of hydrogen is low, a warning can be emitted at a tolerant concn. or less in work environment.

IPC: G01B11/30
Filed: 1993-04-27
Abstract: PURPOSE:To contactlessly measure the surface roughness of a surface to be measured which operates at a high feed speed such as an online process for metal rolling by using a sensed error signal as a focal error signal for servo motions through calculation till the high frequency band. CONSTITUTION:The emitted beam of light from a semiconductor laser 1 is passed through an optical system 2 and condenced by an objective lens 4, and the reflected light by a surface to be measured 20 is two divided so as to generate photo-sensor outputs 61a, 61b. The result is fed to a wide band focal error calculation amplifier 17, and signals from DC to high frequency range are emitted which include a focal error signal 12 for servo motions and a surface unevenness signal. The high frequency of this output is cut 30 to turn into an error signal 12 and further subjected to phase compensation 22 and amplification 23 so that an objective lens actuator 3 is driven, and the focus position of the objective lens 4 is put in pursuit after the mean level of the surface unevenness of the surface to be measured 20. Accordingly a fine surface unevevenness of a steel plate is sensed as a focal error from the focus position and included in the surface unevenness signal. By a BPF 29 this signal is divergently emitted in a roughness signal 51 and waviness signal 52. This enables contactlessly measuring the surface roughness having a high feed speed.

Title: Color information conversion processing method
Inventor: KOJIMA MISAKI
IPC: H04N1/60
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To convert unreproduced color of an image to be outputted into a reproducible color and to avoid occurrence of deformed gradation by using a lightness difference decided definitely by lightness information of an original color. SOLUTION: Image color information is received (S401), and the image color information is converted into, e.g. an Lab coordinate (S402). Then whether or not the color is unreproduced color is discriminated (S403). When the color is discriminated to be an unreproduced color, the color information after conversion is decided by using a lightness difference decided definitely from the lightness of the original color with the same hue to obtain a color on a border line of a reproduced range ($404). Thus, the result of lightness of a desirable reproduced color = C × lightness of original color + D is obtained, where C, D are constants. At first, the constants C, D are decided and a lightness L2 of a reproduced light is obtained. Then the color coordinate of the L2 on the border line of the color reproducible range is obtained.  Thus, the desirable reproduced color such as (L2, a2, b2) is obtained.
