Title: Method for measuring time division multiple spectral emissions
Inventor: NAKAGAWA YASUO
IPC: G01J3/28
Filed: 1982-10-06
Abstract: PURPOSE:To perform spectral photometry in a short time with sufficient measuring accuracy being maintained, by performing time division modulation of the emission from (n) pieces of light sources by the same frequency with the phase being shifted by 360 deg./n sequentially, and simultaneously performing spectral photometry. CONSTITUTION:Light beams emitted from first and second light sources 1 and 2 are modulated by the same frequency so that the phase is shifted by 180 deg. each other by first and second rotary sectors 3 and 4. The light beams are guided to a double monochrometer 8 through a BaSO4 diffuser plate 5 and a mirror 7. The light beams, whose spectrums are divided by the monochrometer 8, which is set at a specified wavelength, are inputted to a photoelectric multiplier tube 9. Its outputs are detected by first and second lock in amplifiers 11 and 12, which are synchronized with the rotary sectors 3 and 4. the measurement is performed by sequentially moving the preset wavelength. Thus the distribution of the spectral emissions of the visual parts from the two light sources 1 and 2 is simultaneously obtained. Therefore the spectral photometry can be performed in a short time, with sufficient accuracy.

Title: Rotary head type magnetic recorder and reproducer
Inventor: UJIYOU TATSUZOU
IPC: G11B5/52
Filed: 1980-12-12
Abstract: PURPOSE:To detect the rotary phase of a rotary drum by an inexpensive device, by providing small-area marks, differing in reflectivity or transmittivity, on the external surface of the rotary drum. CONSTITUTION:A cut part (a) is made at each magnetic-head fitting part so that when a magnetic head 5 and a magnetic-head base plate 4 are fitted to a rotary drum 3, the magnetic head 5 is prevented from touching the rotary drum 3. Light from a light emitting element 15 is emitted to the cut part (a) and its reflected light is photodetected by a photodetecting element 16, so that the other part of the rotary drum 3 generates hardly any output. When (n) cut parts are made, a pulse to the photodetecting element 16 appears at intervals of a 1/n turn, so the rotary phase of the rotary drum 3 is detected easily.

Title: Addressing of liquid crystal cell and liquid crystal apparatus
Inventor: PIITAA UIRIAMU ROSU
IPC: G02F1/133
Filed: 1988-07-14
Abstract: PURPOSE: To extend the operation temperature range by applying a unipolar strobe pulse to a first set of electrodes and applying a bipolar pulse to a second set of electrodes and applying a stabilized AC voltage waveform, which has a frequency higher than a fundamental frequency determined by the state of 'one' of the bipolar pulse waveform, to picture elements at the time of excess over a prescribed temperature. CONSTITUTION: The signal applied to a driver circuit through lines 45, 47, and 48 controls the operation of the driver circuit but doesn't control the voltage applied to a cell 40. This voltage value is determined by a voltage control unit 50 driven by a stabilized power source 51. A temperature sensor 52 connected to a temperature measuring circuit 53 supplies a temperature signal to the voltage control unit 50 provided with a ROM where a table showing relations of temperature to a data pulse voltage, a strobe pulse voltage, and a stabilized voltage is stored.  The temperature sensor is provided to control the waveforms of data and strobe pulses in accordance with the temperature of the cell, and the stabilized voltage waveform whose frequency is twice as high as the fundamental frequency of the data pulse is applied in the case of at least a high temperature, extending the operation temperature range of the ferroelectric liquid crystal cell.

Title: Snap shot dump output processor containing pattern analyzing function
Inventor: NISHIOKA KUNIKO
IPC: G06F11/34
Filed: 1989-07-07
Abstract: PURPOSE:To decrease the output results when the snap shot dump output is applied to a memory storing a large quantity of data by securing a constitution where the data stored in the memory are analyzed, edited and outputted. CONSTITUTION:A user starts a snap shot dump output processor 1 to apply the snap shot dump output to the contents of a memory 2. Then a data input part 3 reads data out of the memory 2. In an analyzing process, a pattern analyzing process part 6 decides whether the data of the same contents are repetitively obtained or not for production of the output data. When the data are not edited nor outputted, the part 6 performs no analyzing process and sets the read data to the output data as they are. Then an editing/output part 5 outputs the output data to an output device 7. Thus it is possible to decreases the output results when the snap shot dump output is applied to the memory 2 containing a large quantity of data.

Abstract: PROBLEM TO BE SOLVED: To inject a liquid material into a narrow packing gap and to enhance the yield of a product by making a discharge port of a needle for a dispenser into a flat form having mutually different hole diameters orthogonally crossed at a center of the discharge port and making it into a shape having the bending shape in the lengthwise direction of the needle. SOLUTION: In the nozzle for a dispenser for discharging and injecting the liquid material into the narrow packing gap, a shape of the discharge port of the needle 2 is made into a flat discharge port 12 having mutually different hole diameters orthogonally crossed at the center of the hole or a circle- connected shaped discharge port 13 having plural circular shapes successively. Thus, the hole cross-sectional area can be increased and fluidity resistance at a time of discharging the liquid material becomes small and also a discharge quantity per unit hr can be increased. By forming the bending part at a middle part in the lengthwise direction of the needle 2, a needle holder 3 does not become an obstacle when the needle 2 is inserted into the packing gap and the liquid material can be discharged by approaching the needle 2 to an adhesive layer under a package.
