Inventor: OSANO MINETADA
IPC: G11B5/53
Filed: 1984-09-06
Abstract: PURPOSE:To attain high-density recording and to record a large amount of voices with a small quantity of magnetic tape for easy transportation, storage and control, by providing plural magnetic heads on a disk to perform the recording and reproduction in an arc from and vertically to the moving direction of the tape. CONSTITUTION:Three magnetic heads 10 are set on a disk 9 and revolved at a fixed speed to move a magnetic tape 8 at a low speed on one or plural arc-shaped tracks 13. Thus those tracks on the tape 8 are recorded consecutively with spaces between several hundred mum and several mum. At the same time, the control signal of a control signal device 11 is recorded at the upper or lower part of a track 12. Then a recording track 13 is controlled to reduce voices with high density. In a reproduction mode, the control signal of the track 12 is detected by the device 11 and the voice data is detected out of the track 13 by the head 10 to obtain voices.

Title: Multiple disk clutch in driving power transmission gear
Inventor: YAMAMOTO MASAJI
IPC: F16D25/063
Filed: 1987-07-27
Abstract: PURPOSE:To promote the radiation of heat in a clutch housing by alternately juxtaposing multiple disk annular clutch plates and clutch disks and, in the parallelly arranged direction central position of these plates and disks, interposing an annular separate plate in thickness larger than that of these clutch plates and disks. CONSTITUTION:Multiple disk annular clutch plates 11 and clutch disks 12 are alternately brought into parallel contact. In almost the central position of this parallelly arranged direction, an annular separate plate 13 in thickness larger than the thickness of the clutch plates and the clutch disks is interposed engaging the direction of rotation of the separate plate with either an input shaft 1 or an output shaft 2. The separate plate 13 radially forms a recessed groove 15. Forming a shape dividing the whole unit into two parts by this separate plate 13 while radiating heat reducing a temperature of oil in a housing 3 because of the larger thickness, a temperature rise is suppressed. While cooling the separate plate 13 because the oil passes through the recessed groove 15, the heat is increasingly radiated.

Title: Method for adjusting optical level
Inventor: MUTO RYO
IPC: H04B10/079
Filed: 1993-06-29
Abstract: PURPOSE:To realize the reception sensitivity of a luminous quantity suitable for temperature, power supply voltage, powder dust, and distance between light receiving elements by informing it to one board when a light receiving level of other board is optimum and setting a light emitting level of the one board and a light emitting level of the other board to be proper. CONSTITUTION:A CPU 1-1 of a main board increases gradually the current of a light emitting element 1-2. When the CPU 1-1 detects a light receiving current of a light receiving element 1-3, the CPU 1-1 stores a current P flowing to the light emitting element 1-2 to stop light emission. Then a CPU 2-1 of a sub board stops the light emission of a light emitting element 2-2. Then the light emitting quantity of the light emitting element 1-2 is decided. On the other hand, the CPU 1-1 of the main board stops the light emitting element 1-2 when an input to a light emitting element 1-3 reaches an optimum value. Moreover, the CPU 2-1 stores a light emitting current Q of the light emitting element 2-2 when the light emission of the main board is stopped. Thus, the setting of the optimum current of each light emitting element of the main board and the sub board is finished.

Title: Power steering apparatus
Inventor: IWAHASHI SATORU
IPC: B62D5/07
Filed: 1982-10-22
Abstract: PURPOSE:To effectively utilize a battery by reducing the speed of the oil which flows in a no-load circulation oil passage and reducing the no-load loss. CONSTITUTION:An electric motor 50 is driven by receiving electric power from a battery loaded on a car through a speed controller 40. A hydraulic pump 60 generates pressurized oil by receiving the rotary power of the motor and feeds oil into a no-load circulation oil passage 72. An oil-pressure controlling part 70 feeds in branched form the pressurized oil formed in the hydraulic pump 60 into an oil feed and discharge passage 74 in accordance with an external operation signal, and operates a power cylinder 80. When a power steering apparatus is judged to be in no-load state by a negative pressure sensor 90, the output of the motor 50 is reduced by the speed controller 40. Therefore, in no-load state, the speed of the oil which circulates in the no-load circulation oil passage 72 is reduced by reducing the revolution speed in comparison with the speed in the case when speed is not controlled at all, and no-load loss is reduced.
