Title: Production of hydrogenated bisphenol compounds
Inventor: FURUMOTO MASASHI
IPC: C07C29/20
Filed: 1992-06-24
Abstract: PURPOSE:To efficiently produce a hydrogenated bisphenol useful as a polymer raw material in a short time by hydrogenating a bisphenol in the presence of a ruthenium catalyst in an alcohol solvent. CONSTITUTION:A bisphenol (e.g. isopropylidene diphenol) is hydrogenated in the presence of a ruthenium catalyst in a >=4C secondary alcohol at 50-250 deg.C under a pressure above the atmospheric pressure for approximately 3hr to produce the hydrogenated bisphenol. The ruthenium catalyst is preferably carried on a carrier (e.g. alumina) because of being readily separated, and is preferably added in an amount of approximately 0.01-0.2wt.% based on the bisphenol of the raw material as the metal ruthenium. Since the reaction conditions are mild and since the reaction is finished in a short time, the deterioration of the catalyst caused by its repeating employments is little, whereby the method is advantageous on the production cost.

Title: Image collection device
Inventor: YAMADA ISAMU
IPC: H04N7/00
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To select an optimum equivalent sampling period by applying A/D conversion to a still analog image for a large number of equivalent sampling periods obtained by shifting the phase with a delay circuit having plural delay taps. SOLUTION: A synchronous clock generating section 11 receives a horizontal synchronizing signal of an analog video signal to start a self-running oscillator 10 and to generate a clock signal of a period T0 =20ns. A delay circuit 131 is made up of 8-stage configuration of a tape step of Tdmin =2.5ns. For example, when a conversion minimum period Tsmin possible for A/D conversion is 100ns and a signal is converted by an equivalent sampling period Td =5ns, a sampling original signal generating section gives a selection signal of a period 20ns to the delay circuit 131 by an instruction from a control section 14, the delay circuit 131 interpolates the signal by two stages of a tap step and provides an output of an equivalent sampling clock at an interval of 5ns via a selection circuit 132. Then data of 20 frames are collected while shifting the phase by 5ns each.

Title: Video signal output circuit
Inventor: SANO YUUJI
IPC: H04N9/64
Filed: 1986-08-14
Abstract: PURPOSE:To adjust the number of color displays without adjusting the level of a luminance signal by inputting the luminance signal to one input terminal of a NAND gate of each channel and connecting a resistance between the other input terminal and the earth and inputting video signals of primary colors to respective anodes and providing a diode to which respective cathodes are connected. CONSTITUTION:A video signal driving transistor TR 6 is turned of through a NAND gate 6 when a signal GIN applied to an input terminal 11 is in the high level in a green channel (the same may be said of the other primary colors). If video signals RIN, GIN and BIN are in the low level though a luminance signal INTIN is in the high level, a current is not conducted to a resistance 20 and one input of a NAND gate 17 is pulled down. Then, the output of the gate 17 goes to he high level, and a luminance signal driving TR 8 is turned off. Consequently, colors are not displayed on a color CRT 1 unless video signals RIN, GIN and BIN of respective colors go to the high level though the luminance signal INTIN is in the high level.

Filed: 1982-10-28
Abstract: PURPOSE:To reduce the searching time by applying rough shift control by the difference between the start time signal of a designated music and the total traveling time signal obtained at a present time point of a pickup based on the information of a potentiometer, then performing optical fine search. CONSTITUTION:With designation of a music number, microprocessor MP8 sets a decoder 11 and an input buffer circuit 14 under an enable state respectively and then fetches the output signal of a potentiometer 5. The output of the meter 5 is converted into the total traveling time signal with reference to a table storing the total traveling time information corresponding to the position of a pickup PU4, and both minute and second signals are loaded to a memory. Then the start time signal of the designated music is read out of information on contents and loaded to the memory. The total traveling time signal is compared with the start time signal to apply rapid traverse or fast rewinding a motor 3. It is decided whether the value of the memory is within a tracking control range of the optical system. If the memory value is within the control range, the end of a rough search is decided to proceed to a fine search. That is, the coincidence is obtained by the control of the optical system between the start time signal of the designated music and the total traveling time signal of the PU4 of that time point.

Title: Liquid crystal display element
Inventor: YOSHIDA TETSUSHI
IPC: G02F1/1337
Filed: 1988-07-29
Abstract: PURPOSE:To obtain effective contrast and a wide visual field angle even in a high time division driving by setting up the orientation processing direction of one base to a direction obtained by rotating the orientation processing direc tion of the other base in the same direction as the twisting direction of a liquid crystal molecular array. CONSTITUTION:The orientation processing direction of a projection side base 2 is set up to a direction obtained by rotating the orientation processing direc tion A1 of an incident side base in the same direction as the twisting direction T of the liquid crystal molecular array. When the array states of liquid crystal molecules (a) between both the bases are developed along the twisting direction, the liquid crystal molecules (a) are arrayed so that the tilt directions of the liquid crystal molecules (a) on both the bases are reversed from each other and the tilt angles of the liquid crystal molecules (a) are gradually reduced in accordance with separation from the surfaces of the bases. Thereby, an optical change against an impressed voltage is increased and the characteristic of a threshold can be sharpened without reducing response speed. Thus, effective contrast and a wide visual field angle can be obtained even in high time division driving.

CONSTITUTION:Cold water is circulated in coils buried in the body 1 of a building. The circulation of cold water causes the body 1 to be cooled and endothermic and heat radiating surfaces 3 for space cooling at a ceiling absorb heat generated from the room inside and human bodies to cool down the room inside and radiate cold air. The humid air generated in the room inside end containing latent heat flows into the vaporizer 9 of a humidifier 8 and the room air is cooled to condense moisture and gas heat medium is condensed and compressed by a compressor 11. The heat radiated from the compressor 11 is removed by an after-cooler 12 attached to a heat releasing port, of the compressor 11. Such conditions that sacked air end cold air are accumulated upwards and downwards respectively end subcooling tends to take place to obtain humidifying effect are able to be eliminated.
