Title: Method for measuring concentration of hydrogen peroxide
Inventor: AKIYAMA AKITANE
IPC: G01N27/48
Filed: 1989-09-28
Abstract: PURPOSE:To measure the concn. of hydrogen peroxide in a short period of time with a high detection sensitivity by impressing a triangular wave signal of a prescribed voltage to an electrode to active the electrode prior to measurement and obtaining the difference in the current values detected by two times of pulses. CONSTITUTION:One pulse of the triangular wave voltage is first impressed to the working electrode 2. The 1st pulse voltage of 750mV is then impressed for one second and the 1st current value flowing in the electrode 2 is measured in the subsequent T1 period. The 2nd pulse voltage of 1100mV is in succession impressed to the electrode and the 2nd current value flowing in the electrode 2 in the subsequent T2 period is measured. The difference between the 1st and 2nd current values is computed by a microcomputer 8. Nearly a linear relation is obtd. in a prescribed range between this differential current value and the concn. of the hydrogen peroxide and, therefore, if the relations between the known concns. of the hydrogen peroxide and the differen tial current values are previously obtd. and the characteristic table thereof is storaged, then the concn. of the hydrogen peroxide is instantaneously calculated from the detected current value in accordance with such stored data.

Title: Photo semiconductor device
Inventor: WAKAO TADAKI
IPC: H01L31/12
Filed: 1990-09-20
Abstract: PURPOSE:To make smaller a tracking error in comparison with that of a device where indirect monitor is conducted in the successive stage of a laser diode by obliquely cutting the end part of an optical fiber which receives the front end emitting light of laser diode and then inputting reflected laser beam at the cutting surface into a photosensitive element for monitoring. CONSTITUTION:The end part of an optical fiber 11 is obliquely cut and a light input surface of a photodiode 14 used for monitoring is directioned to the laser reflecting direction from the cutting surface in the end part of optical fiber 11 and position of such light input surface is adjusted so that the optimum light input can be obtained. A cutting angle theta of the end part of optical fiber 11 is limited within 45 deg. in order to provide sufficient amount of incident light to the optical fiber 11 and the optimum angle theta is determined considering an output level of laser module and photodiode 14 within the range that the reflected laser beam does not return to the laser diode 13. With this method, variation of optical output from the optical fiber due to difference of temperature characteristic of laser diode on the front and rear side of laser can be prevented.

Abstract: PURPOSE:To exactly detect the beginning of a rainfall by combining an electrode in which a pair of electrode opposed through a thin clearance are formed like the plane, and a means for detecting a fact that the electrodes are brought to bridging by a raindrop. CONSTITUTION:When an electrode plate 11 is installed out of doors so that the electrode surface 11b becomes the upper face, when a rain falls and a raindrop W adheres onto an insulating substrate 11a, a thin clearance (d) between electrodes 11b1, 11b1 is brought to bridging through the raindrop W. In this case, an electric insulation resistance value between the electrodes 11b1, 11bb1 drops extremely, therefore, a detecting circuit 12 detects it and can output an output signal S. Accordingly, the beginning of a rainfall can be detected and informed exactly.

Filed: 1984-11-29
Abstract: PURPOSE:To confirm the focusing condition by the existence or otherwise of the flickering on the monitor screen, by shifting the sampling position by each field at the monitoring device which sends picture sampling signal to the displaying device. CONSTITUTION:A picture signal 30 from a video camera 24 is sampled by a sample and hold circuit 21, and inputted to a liquid crystal display 10 together with the synchronizing signal issued from a synchronized signal generator 23. At this time, the sampling position is switched by sampling phase switching circuit 22 by each field. Then, when the focus is rightly adjusted, the signal difference becomes larger due to the difference of sampling position, and the flicker on the monitor screen becomes larger accordingly. Therefore, in or out of the focus is easily discriminated by the size of flicker even using a display device with a small number of picture element such as liquid crystal display.

Title: Image signal processor
Inventor: TAMER GREGORY GEORGE
IPC: H04N5/60
Filed: 1986-10-22
Abstract: An IF signal filter in the IF sound channel of a television receiver exhibits peak amplitude responses which are unsymmetrical and slightly offset from the nominal picture and sound carrier frequencies by an amount dictated by the amount of tilt introduced by the tuner and the IF signal processing section. As a result, a filtered IF signal applied to a sound demodulating system exhibits a substantially symmetrical characteristic with respect to both the sound and picture carrier frequencies, yielding reduced audio buzz and harmonic distortion.
