Title: Focusing detecting device
Inventor: YAMADA KUNIHIKO
IPC: H04N5/232
Filed: 1992-06-26
Abstract: PURPOSE:To attain a precise focusing to an object whose illuminance and contrast is low by comparing the values of the differential waveforms of a video signal before and after the point of time when the maximum value of the differential waveform of the video signal is obtained, and operating a focusing detection. CONSTITUTION:The video signal from an image pickup element 31 is amplified to an appropriate level by a preamplifier 32, transmitted through a gate circuit 34, differentiated by a differentiating circuit 35, and turned to an absolute value by an absolute value circuit 36. The maximum value of the waveform of the output of the circuit 36 is held by a peak/hold circuit 39. The output of the circuit 36 and the output of a delay circuit 38 are sampled/hold by S/H circuits 40 and 41 by using the hold pulse, the values of the differential waveforms before and after the maximum value are compared by a logical control part 42, and a prescribed arithmetic processing is operated. The control part 42 judges the focusing state of a photographing lens 30 based on the arithmetic result, and controls a motor driving circuit 44 to allow it to operate the focusing. Thus, the precise focusing can be attained to the object whose luminance and contrast is low.

Title: Method and device for sample time measurement
Inventor: KARIBE KOUJI
IPC: G04F10/00
Filed: 1989-07-26
Abstract: PURPOSE:To measure a sample time without reference to the aperture time, offset voltage, etc., of a DUT by inputting the output of the variable frequency signal generator to a device to be measured and connecting an amplitude measuring instrument to its output. CONSTITUTION:The sample time measuring instrument consists basically of the variable frequency generator 1, DUT 2, and an AC voltmeter 3 and includes a timing generator 4 which supplies a sample instruction to the DUT 2. In this case, even if the phase relation of the sample time to an input signal 5 varies from 6 to 8, the integer period of the input signal 5 is averaged, so an AC component is removed and the output of the DUT 2 is therefore only a DC component, which is inputted to the AC voltmeter. Consequently, the sample time is N/fz, where fz is an input signal frequency at which the output AC component disappears and N is the number of cycles of the input signal in the sample time. For example, when fz is searched fro from a low frequency and obtained, N = 1 and the sample time becomes 1/fz and is easily found.

Title: Preparation of (meth)acrylic ester polymer
Inventor: ODERA JUNZO
IPC: C08F4/12
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To polymerize a (meth)acrylic ester in a more improved polymerization yield than in a water-free solvent by using a rare earth metal triflate as a polymerization initiator in the presence of a water-containing solvent, the rare earth metal triflate thereby becoming recoverable and utilizable. SOLUTION: When a (meth)acrylic ester monomer is polymerized by using a rare earth metal triflate [a compound of the formula (wherein M is a rare earth metal element)] as a polymerization initiator in the presence of a solvent, 1-10,000mol of water is added per mol of the rare earth metal triflate. Here, the rare earth metal triflate is used in an amount of 0.001-0.1mol per mol of the (meth)acrylic ester monomer. Further, the solvent used includes a solvent which is compatible with water and capable of dissolving the polymer formed (e.g. 1,4-dioxane). The polymerization using the above-mentioned polymerization initiator in the presence of the water-containing solvent gives a more improved yield than the case where the polymerization is effected in a water-free solvent and also makes the recovery and reutilization of the rare earth metal triflate possible.

Abstract: PURPOSE:To improve the mass-productivity by applying an organic orienting film material to a glass substrate where liquid crystal is charged and rubbing its surface, and dipping the substrate into a solution of a specific kind of silane coupling agent with specific concentration (including 0%) and setting a tilt angle. CONSTITUTION:The glass substrate where the liquid crystal is charged is coated with the organic orienting film material and its surface is rubbed; and the substrate is dipped into the solution of the specific kind of silane coupling agent with specific concentration and the tilt angle is set. Thus, the glass substrate is coated with the organic orienting film material and its surface is rubbed; and the substrate is dipped into the silane coupling agent and the kind and concentration of the silane coupling agent are varied to set the tilt angle. Consequently, even when many kinds of liquid crystal cells which differ in tilt angle are manufactured in small quantities, the reference orienting film material can be limited to one kind and the mass-productivity can be improved.

Title: Redundancy type thyrister valve fault diagnosis
Inventor: YAMAMOTO MITSUTOSHI
IPC: H02M1/088
Filed: 1986-08-22
Abstract: PURPOSE:To improve safety and reliability, by providing a delay circuit, e.g., counters or timers, to a minority opinion interpretation circuit. CONSTITUTION:In case there is a valve fault diagnosis device interpreted as a minority opinion, only the corresponding one of the counters 14a-14c counts up a synchronizing signal, which will be set if it exceeds the predetermined count value. Through this processing the outputs of AND gates 10d-10f are delayed by a prede termined time. When either one of the counters 14a-14c is set, the corresponding one of flip-flops 13a-13c is set, by which either one of OR gates 11a-11c is given a 'H' signal. On this account, the output of either one of valve fault diagnosis devices 8a-8c interpreted as a minority opinion is nullified.
