Title: Optical information device
Inventor: MIYAZAKI TOMIYA
IPC: G11B27/10
Filed: 1983-07-08
Abstract: PURPOSE:To avoid a reading error of track addresses and to shorten the retrieving time by providing a means which produces the signal incapable of reading address signals owing to the shortage of these address signals because of a drop- out, etc. CONSTITUTION:For an address signal A' having the shortage of its data due to a drop-out, etc., an address identifying circuit 20 is restarted by an address signal gate (h) before the address full signal is produced at the area of the next address signal A as shown by (g). Thus an address full signal (i) is obtained by the signal A, and then an address information signal is obtained. The address full signal and the gate (h) are fetched to a microcomputer 26 to know that the reading is impossible for the address signal. It is possible to confirm the track address information by reading the address information on the preceding and next tracks.

Inventor: NODA SHIYOUHEI
IPC: G01K11/20
Filed: 1979-09-28
Abstract: PURPOSE:To cause no attenuation virtually to the Raman beam but cause attenuation only to the background beam by providing the polarizer at the reception side of the Raman beam and then securing a coincidence between the polarizing direction of the polarizer and that of the Raman beam, thus increasing the S/N. CONSTITUTION:The laser beam from the laser 1 is focused through the condenser lens 2 at the spot where the measurement is desired for temperature. Then both the low- and high-order stokes beams generated from the focal area are detected by the photoelectric mulitplier 9 and 10 and via the polarizer 4. The ratio of intensity is calculated by an operator betweeen these both stokes beams, and the temperature is obtained from the value calculated through the operator and then indicated through the indicator 14.

Title: Manufacture of semiconductor chip and thereby formed semiconductor chip
Inventor: NISHIKAWA HIROYASU
IPC: H01L21/82
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To efficiently produce various types of semiconductor chips by forming equally sectioned chip regions on a semiconductor wafer with input/output circuit blocks and functional circuit blocks and dicing the wafer into individual semiconductor chips. SOLUTION: For functional circuit blocks C11 -C14 having mutually different functions are formed on the central area of a C-pattern e.g. in a gate array system. As the area is small, different wiring designs are applied to entirely formed common basic cells to form four functions collected on one chip region 1a. Around the collected functional circuits C11 -C14 , input/output circuit blocks C21 for transferring signals from and to externals are formed. Since the functional circuit blocks having a smaller area than that of IMS are collectedly formed on one chip region 1a, various types of chips can be produced.

Title: Electrinic hour striking device
Inventor: ITOYAMA HIROSHI
IPC: G04G13/00
Filed: 1977-10-15
Abstract: PURPOSE:To generate the hour striking sounds of such a tone as is stable irrespective of the changes in temperature or voltage by generating striking frequency pulse signals in response to the frequency dividing output of a frequency lower than the sound generating clock signals so that these clocks may be modulated with the striking frequency pulses. CONSTITUTION:The oscillatory frequency of a quartz oscillator 1 is subjected to frequency division to generate sound generating clock signals in response to suitable frequency dividing output. In response to the frequency dividing output of a lower frequency than the sound generating clock signals, striking frequency pulse signals are generated to modulate the clock signals so that hour striking sounds may be generated from a speaker 12. With such construction, since a self-running multivibrator is not used, it is possible to generate the hour striking sounds of such a tone as is stable irrespective of the changes in temperature or voltage.

Title: Magnetic head
Inventor: WATANABE MAKOTO
IPC: G11B5/245
Filed: 1977-10-18
Abstract: PURPOSE:To reduce crosstalk between tracks with narrow tracks by making the gap length of side gaps integer times longer than the longest wavelength of the signals used, with a magnetic head for magnetic reproduction. CONSTITUTION:Magnetic material blocks 1, 2 are butten together and bonded by a bonding agent 7 such as glass or the like to form a gap part, whereby the ring form magnetic head is formed. The gap length 3 for write/read is about 1/3 the minimum magnetization inversion spacing out of the signals used in ordinary digital recording. Side gaps of a gap length 4 are formed on both side face parts of a track width 5 for recording and reproducting. The side face gap length is given the effective gap length integer times the longest wavelength of the signals used. Thereby, the signals being recorded by being leaked to the track side faces are reduced at the writing and high track density recording with less effect by the crosstalk signals from the adjoining tracks is made possible at the reading.

Title: Film feeder and optical instrument provided with the same
Inventor: NAKANO SHINGO
IPC: G03B1/62
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To leave the end part (tongue part) of a film outside a cartridge by a nearly specific amount even if a rewinding speed is varied due to the fluctuation of the voltage of a battery, the load unevenness of the film, a change in ambient temp., etc., by counting the time needed to rewind a specific amount of film, at the nearly end of the film at the time of executing a rewinding operation and setting the residual operation time in accordance with the counted time. SOLUTION: When the upper perforations 19b of the film 19 reach the position of a detecting window 25b, the upper perforations 19b are detected by a photoreflector. The number of the detection signals is counted to detect the feed rate of the film 19. At this time, a rewinding time for a specific rewinding amount is counted. Then, the residual operation time up to the stopping of the rewinding operation (for instance, the time to stop the rewinding operation in a state where the rewound end part of the film 19 remains outside the film cartridge 20) is calculated on the basis of the counted rewinding time. Thus, the tongue part is surely prevented from remaining in an aperture.

Abstract: PURPOSE:To prevent the recording of noise and to improve the rise characteristics, by elevating quickly the voltage level of the inverted input terminal of a regenerative amplifier simultaneously with power-on in an amplifier starting device used in a magnetic recording and reproducing device or the like.

Filed: 1986-06-02
Abstract: PURPOSE:To shorten locus correcting time by storing the correction data of the succeeding teaching point based upon a correction command signal in a memory at the time of working a robot by the working data of one teaching point. CONSTITUTION:A CPU 1 reads out the succeeding position data of a certain teaching point stored in the memory 2 and outputs deviation data obtained by subtracting a robot current value data counted by a current value counter 13 from the position data to a detector 5. When a correction command signal based upon the close of a correction switch 41 or 42 is inputted up to the period that a request command for the deviation data of the succeeding reaching point is outputted from the detector 5, an I/O device 3 stores the correction data of the correcting direction in the memory 2. When the request command for the deviation data of the succeeding teaching point is outputted from the detector 5, the CPU 1 adds the correction data of the succeeding teaching point read out from the memory 2 to the deviation data and outputs the added data to a servo circuit 6. Since the locus of the robot can be corrected during the working of the robot, the time required for the correction can be sharply shortened.
