Title: Spectrum spreading communication system and receiving device
Inventor: FURUYA YUKIAMI
IPC: H04B1/69
Filed: 1981-05-08
Abstract: PURPOSE:To improve the using efficiency of a frequency, by switching the register initial value of an M series generator at the transmitting side and detecting the time position where the peak value emerges in the adverse decentralization mode at the receiving side respectively. CONSTITUTION:A signal series to be transmitted is supplied through a termial 100 and stored in an N-stage register 110. The data of the register 110 is loaded  as the initial value of an N-stage M series generator 120. The generator 120  transmits the signal of a chip of double period to a modulator 130 based on the  above-mentioned initial value. The modulator 130 trnsmits the output of the generator 120 after double-phase modulation. A signal receiver detects the correation with the M series of a specific phase through a matching filter 170 for  a recived signal. The peak value of the filter 170 is detected by a maximum  value detecting circuit 180. The time phase of that moment is applied through a  converting circuit 190 in the form of the initial value of the M series generator.  Thus the N-bit signal can be detected.

Title: Automatic air feeder for motor pump
Inventor: KUNISAKI SHIGERU
IPC: F04D13/16
Filed: 1982-04-22
Abstract: PURPOSE:To regulate the air supply into the pressure tank automatically, by lifting the valve body upon increase of the air volume in the pressure tank to choke the joint opening while holding the choked state through the surface tension of foam. CONSTITUTION:Upon increase of air in a pressure tank 1, first valve body 11 will lift quickly in the upper valve chamber 4 to choke the opening of a thrugh- hole 9a. Consequently the air supply into the pressure tank 1 is blocked by an automatic air supply mechanism 18 to regulate the air volume in said tank 1 automaically while to prevent the overfeed. Since the first valve body 11 is held by the surface tension due to the form near the upper valve seat 9, the opening of the through-hole 9a is choked to block the air feed into said tank 1.

Title: Device of forming image of object
Inventor: MAKINO HIROSHI
IPC: G03B13/36
Filed: 1994-04-07
Abstract: PURPOSE:To uniformize brightness of a formed image on a photodetector even when a direction of an object is different by limiting a light passing through an image lens by means of a shade member provided in the vicinity of the image lens. CONSTITUTION:A shade member 6 shades an incident light of a part X of an image lens 3 to allow an incident light of a part Y indicated by oblique lines to pass therethrough. Thereby, incident rays of light to the lens 3 passing near the shade member 6 rather than rays of light L1 (Solid line), L2(dotted line), L3(dashed line) passing around an edge of the shade member 6 are shaded by the member 6 not to be entered into a photodetector 8. As a result, only rays of light passing the effective passing part Y (indicated by oblique lines) of the lens 3 focus on positions (a), (e), (f) of the photodetector 8, respectively. Therefore, when using the lens 3 having a great aperture diameter in the high speed measurement of a distance, it is corresponding to the scanning of the electric signal of the photodetector 8.

Title: Frequency measuring apparatus
Inventor: SHIRAKAWA HIROSHI
IPC: G01R23/10
Filed: 1989-03-22
Abstract: PURPOSE:To obtain a correct measured value with a minimum necessary frequency of measurement by detecting arrival of data for calculating frequency at an expected amount to nullify data as given when the inputting of signals to be measured is stopped. CONSTITUTION:A maximum time counter 17 starts to work at 'H' of a starting signal 101 and a measuring operation signal 105 rises synchronizing a rising of second pulse of a square wave signal 104 as a signal 102 to be measured to activate a waveform counter 3, a time counter 5 and an expected time counter 16. As an expected time passes without the interruption of the signal 102 to be measured, an output of the counter 16 goes to 'H' and a not output of an FF 14 to 'H' to clear FFs 11 and 12 while a microcomputer 4 calculates a frequency of the signal 102 to be measured based on outputs of the counters 3 and 5. When the inputting of the signal 102 to be measured is stopped before the passage of the expected time, an output of one-shot circuit reaches 'H' and a reset signal R1 is generated from a microcomputer 4 thereby nullifying a measured value.

CONSTITUTION:Each member of movable-side sections 241a and 241b and fixed- side sections 25a and 25b constituting a pivot bearing section is constituted by selecting materials for making the sections so that the expanding and contracting quantities of the sections 241a and 241b and 25a and 25b at the contacting section in the axial direction of the rotation caused by a change in temperature can become almost equal to each other. Therefore, the positional relations and pressure relations between the pivot bearings 241a and 241b and pivot supporting section 25a and 25b become such that all of the pivot supporting sections 25a and 25b and pivot bearings 241a and 241b expand and contract by the same quantity in the same direction. Accordingly, the positional and pressure relations do not change even if the ambient temperature changes and smooth rotation can be obtained always.

Title: Magneto-optical recording system
Inventor: KOBAYASHI TADASHI
IPC: G11B11/105
Filed: 1987-03-26
Abstract: PURPOSE:To attain overwriting by using a medium with the vertical magnetizing film of a two-layer structure consisting of two magnetic layers which fulfil prescribed conditions on a substrate, providing a magnetic field generation part in a place different from a recording head at the time of recording, and recording with binary laser power. CONSTITUTION:A first magnetic layer 1 has a low Curie temperature TL and a high coercive force HH, and a second magnetic layer 2 has the high Curie temperature TH and the low coercive force HL. A compensation temperature TCOMP is provided between room temperature and the Curie temperature. When a temperature is raised from an unstable state (a) in which interface magnetic domain walls exist, the coercive force of the magnetic layer 1 is reduced the coercive force of the magnetic layer 2 is increased, and the magnetizing of the magnetic layer 1 is inverted for setting both layers to parallel, whereby it comes to a state (b). When the temperature is raised furthermore, it exceeds the compensation temperature TCOMP of the magnetic layer 2 and it comes to a state (c), whereby the magnetizing of the magnetic layer 2 is made reversible. If the temperature is raised furthermore, the coercive force of the magnetic layer 2 becomes small and is reversed due to a bias magnetic field HB as a state (d). Here, the magnetic layer 1 improves and recording is executed with the binary laser power in the magnetic field generation part 2, whereby overwriting is attained.

Title: Optical head
Inventor: NISHII KANJI
IPC: G11B7/135
Filed: 1983-04-20
Abstract: PURPOSE:To eliminate the generation of noise and to improve the record/reproduction characteristic and to reduce the thickness of an optical head, by engaging a 1/4 wavelength plate to a semicircular groove part to control revolution and to obtain the maximum ratio of separation between the light projected from a semiconductor laser and the light sent back from a disk. CONSTITUTION:A disk-shaped 1/4 wavelength plate 5 is guided along the circumference of a semicircular groove part 7a and controlled for its revolutions so as to obtain the maximum separation of the light R2 sent back from a disk. In addition, the plate 5 has an inclination to a polarized beam splitter 4 and therefore it is possible to obtain an optical path for the reflected light on the lower surface 5a of the plate 5 which is different from the optical path of the output light R1 of the laser 1. This can prevent a feedback connection with the laser 1 and eliminate generation of noises. Thus the satisfactory record/ reproduction characteristics can be secured for an optical recording/reproducing device. Furthermore the thickness of an optical head is reduced since the plate 5 is attached directly to the upper surface of the splitter 4. This reduces overall thickness of the optical recording/reproducing device.
