Title: Recording method of pcm signal
Inventor: SUGIKI HIROSHI
IPC: G11B15/467
Filed: 1983-04-30
Abstract: PURPOSE:To facilitate the detection of a pilot signal for tracking control and the interpolation processing of a dropped-out signal at a reproducing time by recording this pilot signal in an area, which is different from an area where a PCM signal should be recorded, of the same track as the PCM signal. CONSTITUTION:The pilot signal for tracking control is recorded in the first area AT1 of every other track TA, and the pilot signal for tracking control is recorded in the second area AT2 of every other track TB. At a normal reproducing time, levels of pilot signals from areas AT2 of both adjacent tracks TB are equalized with respect to a head HA when the corresponding track TA is scanned. Levels of pilot signals from areas AT1 of both adjacent tracks TA are equalized with respect to a head HB when the track TB is scanned. The pilot signal is recorded in the area different from that of the PCM signal in this manner to detect and erase easily the pilot signal at a reproducing time.

Title: Multiprocessor system
Inventor: KOBAYASHI NAOKI
IPC: G06F15/177
Filed: 1989-03-29
Abstract: PURPOSE:To flexibly cope with the increase and the reduction of the number of processors by constituting each selecting circuit so that the memory request as the select output of another selecting circuit and that of another processor are inputted to the selecting circuit. CONSTITUTION:A (n-1)th selecting circuit 10 (n-1) alternately outputs memory requests of outputs of (n-1)th and n-th processors (n-1) and (n). Hereafter, a k-th selecting circuit 10.k where (k) is a natural number satisfying 1<=k<(n-1) alternately outputs the memory request of a k-th processor (k) and the select output of a (k+1)th selecting circuit 10 (k+1), and the select output of a first selecting circuit 10.1 is supplied to a memory 20. In each of these selecting circuits, two systems of memory request inputs are selected in accordance with prescribed precedence. For example, the memory request which first arrives is preferentially outputted, and the memory request from the processor closer to the memory 20 is preferentially selected in the case of simultaneous arrival of memory requests. Thus, this system flexibly copes with the increase and the reduction of the number of processors.

Title: Automatic control system of vehicle stepless transmission
Inventor: OGAMI MASAAKI
IPC: B60W10/10
Filed: 1985-04-11
Abstract: PURPOSE:To achieve effectual use of coasting energy of a vehicle and effective operation of the engine brake by decreasing a desired inlet negative pressure when the accelerator is off and increasing the desired inlet negative pressure when the accelerator is on. CONSTITUTION:A transmission gear ratio control circuit 10 is employed to detect the inlet negative pressure of the engine to control the transmission gear ratio. Then, when the accelerator is off, setting of a desired negative pressure to a low value by a reference value setting circuit 3 causes the transmission gear ratio to be changed over to the high-speed gear side so as to lower the inlet negative pressure. While, in this condition, when the brake is operated, the reference value setting circuit 33 sets the desired inlet negative pressure to a higher value and the transmission gear ratio is changed over to the low- speed gear side to increase the inlet negative pressure, permitting intensive operation of the engine brake.

Filed: 1988-03-30
Abstract: PURPOSE:To reduce a measuring error, by newly providing a bulkhead having a recessed part provided to the front surface thereof so as to form a communication passage between said bulkhead and the second bulkhead provided on the downstream side of a jet nozzle. CONSTITUTION:A third bulkhead 9 is newly provided so as to form a communication passage 17 between said bulkhead and the second bulkhead 11 provided to the downstream part of a jet nozzle 3 and a recessed part 9a is formed to the surface on the side of the nozzle 3 of the bulkhead 9. The disturbance of a jet stream becomes large by the recessed part 9a provided to the front surface of the bulkhead 9 and, even when a flow rate is slight, the flow direction of the jet stream can be stably changed over. When a fluid begins to flow in a return flow passage 7a or 7b with the change of the flow direction of the jet stream from the nozzle 3, the stationary fluid present in the flow passage 7a or 7b is carried away to the communication passage 17 by the inflow fluid not to obstruct the inflow of the fluid. Therefore, the inflow fluid can be allowed to smoothly flow to a drain passage 10a or 10b and a measuring error is reduced.

IPC: B61L23/14
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To increase a quantity of information without increasing resonance frequencies of a pick up on ground. SOLUTION: A pick up on ground 11 has plural sets of resonance circuits consisting of switches (S1 -S4 ) to connect and disconnect a coil D (L1 -L4 ), a capacitor C (C1 -C4 ), a coil L and a capacitor C. When a train travels and electromagnetic coupling is made between the pick up on ground 11 and a pick up aboard 12, a received signal outputted from a secondary coil of the pick up aboard 12 varies in accordance with one or plural resonance frequencies set for the pick up on ground 11. Information corresponding to one or plural frequencies set for the pick up on ground 11 is outputted by amplifying the received signal by an amplifier 21 and selecting by a filter 15a-15d.  A quantity of the information outputted from a device aboard 30 is determined by a combination of plural resonance frequencies of the pick up on ground 11, and the quantity of the information transmitted can be substantially increased by changing the combination of the resonance frequencies of the pick up on ground 11.

Title: Slope-spraying material and slope-spraying process using the same
Inventor: MIZUSHIMA KAZUYUKI
IPC: C04B111/20
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the strength deterioration caused by drying with good workability maintained by including a hardening accelerator containing cement, cement, calcium aluminate and gypsum, a setting retarder and water and setting a specific working life. SOLUTION: The calcium aluminate in the hardening accelerator is prepared by firing a mixture of starting materials for CaO, Al2 O3 and can cause initial coagulation of cement concrete. The amount of the gypsum in the hardening accelerator is 50-250 pts.wt., per 100 pts.wt. of the calcium aluminate, and the amount of the hardening accelerator is 5-20 pts.wt., per 100 pts.wt. of the cement. The setting retarder delays the coagulation of the cement concrete, and a commercially available product can be usually used and its amount is 0.3-5 pts.wt., per 100 pts.wt. of the cement. The pot life for the slope-spraying material is set to 20-180 minutes. The time less than the lower limit is insufficient for troweling time, while the time more than the upper limit lowers the development of the long-term strength.
