Title: Active suspension device for vehicle
Inventor: MIICHI YOSHIAKI
IPC: B60G23/00
Filed: 1990-08-20
Abstract: PURPOSE:To accurately detect a vibration input object for hydraulically controlling the vibration damping force of a hydraulic-pressure sustaining means to the optimum, even if a vehicle body is oscillating up and down, by subjecting the detection signal from a vibration-input detection means to filtering processing for eliminating the bad influence due to the vertical oscillation of the vehicle body. CONSTITUTION:The detection signal of a preview sensor 33 is supplied to a band-pass filter circuit 30a, and the signal value of a vertical G sensor 31 is supplied to the filter circuit 30a. The filter circuit 30a sets a filter-peak frequency in response to the vertical acceleration of a vehicle body detected by the vertical G sensor 31, and filtering processing is carried out by multiplying the detection signal of the preview sensor 33 by the frequency characteristic gain being determined in response to this filter-peak frequency. Thus, the signal in which the detection error signal that has been superposed by the vertical movement of the vehicle body has been removed is supplied to a processing and shaping circuit 30b for being compared with a prescribed judging value, and when the signal value is larger than the judging value, a preview control signal is supplied to a control logic circuit 30c.

Title: Method and device for searching wiring route
Inventor: SUZUKI TAKASHI
IPC: H01L21/82
Filed: 1990-08-22
Abstract: PURPOSE:To guarantee the completeness of lattice point information and to search a lowest cost route by dividing lattice points to be handled into groups and executing a cost development processing for each group according to a maze method to parallelly process the cost development. CONSTITUTION:The lattice points are divided into groups according to a fixed rule so as not to have command adjacent lattice points in the same group, and the parallel development processing is executed in each group. Namely, since the same adjacent point is not shared at every lattice point in the same group when grouping the lattice points to be handled by the maze method, reference and update processings are not simultaneously executed to arbitrary adjacent lattice point information even when parallelly executing the reference and update of the adjacent lattice point information from the lattice points in the same group in the case of executing the cost development processing from a certain lattice point on a wave front to the adjacent lattice point. Thus, the search of the lowest cost route is guaranteed even in parallel processing.

Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To provide the key data extract circuit that extracts scramble key data in an FM multiplex broadcast receiver receiving scrambled transmission data. SOLUTION: A shift register 202 receives sequentially a demodulated FM multiplex broadcast signal.

The glass is elongated to about 15mm diameter and the porous glass is deposited thereon by an external deposition method. The material is then immersed into the alcohol soln. of the ErCl3 of the lower concn. than before and is similarly vitrified to the transparent glass. The conc. of the ErCl3 is successively lowered and this stage is repeated about 5 times.

Abstract: PURPOSE:To perform simultaneous time monitoring in plural communication means with a small scale of time monitoring means by performing the connection and connection releasing of the plural communication means with plural time monitoring means whose total number is less than that of the communication means arbitrarily. CONSTITUTION:The plural time monitoring means whose number is less than that of the communication means, and a connection control means to perform the connection and connection releasing of an arbitrary communication means with an arbitrary time monitoring means are provided.

Filed: 1987-09-03
Abstract: PURPOSE:To correctly execute the loading onto a head drum without loading forcible operating force, by executing the remaining movement after the tape is once moved and stopped at a third position located in the middle of both positions in the movement between a first position and a second position. CONSTITUTION:In a loading mode, at a first step, a magnetic tape is guided from a first position La to a third position Lc between the first position La and a second position Lb, once stopped, and at the next step, the magnetic tape is guided from the third position Lc to the second position Lb. In an unloading mode, at the first step, the magnetic tape is guided from the second position Lb to the third position Lc, once stopped, and at the next step, the magnetic tape is guided from the third position Lc to the first position La. Thus, in the loading, the forcible operating force is not loaded to the magnetic tape and on the tape travelling path, the loading is executed to a head drum at a correct splicing angle.

Title: Multilayer printed wiring board
Inventor: MISAWA HIDETO
IPC: H05K3/46
Filed: 1987-09-02
Abstract: PURPOSE:To obtain a multilayer printed wiring board with low dielectric constant by using a specified resin for an inner layer.

Title: Optical reflector detecting apparatus
Inventor: NOMICHI AKIO
IPC: G01C3/06
Filed: 1989-08-25
Abstract: PURPOSE:To improve the combining efficiency of receiving and emitting light beams with a simple structure, to omit an optical stop mechanism and to make it possible to ensure the detection at a near distance by providing two light emitting parts which project parallel light and light having a wide directional angle, and selecting the two light emitting parts in correspondence with the received signals at a light receiving part. CONSTITUTION:A first light emitting part 11 projects collimated light (parallel light) for measuring a far (long) distance to a reflector. A second light emitting part 12 projects light having a wide directing angle for measuring the near distance. A light receiving part 15 receives the reflected light from the reflector. When only the collimating light from the light emitting part 11 is present, the amount of the received light is remarkably decreased at the very close distance owing to the position deviation from the light receiving part 15. When only wide directional angle light of the light emitting part 12 is present, the amount of the received reflected light is decreased, but the decrease in amount of the received light at the very close distance does not occur. Therefore, when the remote distance is measured, the light emitting part 11 is selected. When the close distance is measured, the light emitting part 12 is selected. The light projections from the light emitting parts 11 and 12 are switched in response to the distance to the reflector. Thus the measurement from the remote distance to the close distance can be performed. Furthermore, an optical stop mechanism is not required.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To allow the facsimile equipment to receive an additionally sent original as the same original without being separated from the previous original sent before. SOLUTION: In the case of sending an original to be added to an original sent before, a sender adds the same identifier as that added to the previously sent original to the original to be added and sends the resulting original.

Furthermore, the identifier of the received original is read and whether or not the received original having the same identifier is stored in the storage device is discriminated (S4). In the case that the original having the concerned identifier is not stored in the storage device, the received original is stored as a new original (S5).  In the case that the original with the concerned identifier is stored, the received original is added to the stored original with the same identifier (S6) and stored as a new original (S7).
