Title: Repeater
Inventor: HORI MASAHIKO
IPC: H04L25/52
Filed: 1986-10-31
Abstract: PURPOSE:To perform transmission of data with high accuracy by reproducing newly a preamble part by an amount equal to the normal data length during relay of the packet data. CONSTITUTION:The packet data demodulated and outputted from a demodulator 2 is supplied to a shift register 14 and a preamble part head detecting circuit 8 respectively. A counter 25 starts counting the transmission clocks received from a modulator 4 and supplies its count value to an FIFO circuit 6, a memory 20 and a control circuit 24 respectively. Thus the data on the bit pattern of a preamble part stored previously in the memory 20 is read out. In such a way, a new preamble part is reproduced excluding the preamble part included in the received packet data. Thus a preamble part having normal data length tp is added to a data part regardless of the number of omitted bits of the received preamble part.

IPC: G02F1/35
Filed: 1991-10-09
Abstract: PURPOSE:To uniformly disperse hyper-fine particles in a matrix by alternately performing a process for depositing the material of hyper-fine particles to be a raw material on a substrate after vaporizing the material in an inert gas by laser heating and a process for forming the matrix on the substrate after the material to be the raw material of the matrix is vaporized by laser heating. CONSTITUTION:The dispersion material is obtd. by alternately performing the following processes. One process is to vaporize the raw material of hyper-fine particles (e.g. CdTe polycrystalline wafer) in an inert gas (e.g. Ar) by laser heating and to cool the vapor rapidly by collision with inert gas so that hyper- fine particles 12 are synthesized from the raw material and deposited on a substrate 10 (e.g. quartz). The other process is to vaporize the raw material of a matrix (e.g. S:O) by laser heating and forming the matrix 11 on the substrate 10. By this method, dispersed material in which fine particles in several one to several 10nm particle size are dispersed at high density without flocculation of a particles can easily be obtd. in a short time. Moreover, the crystallinity of hyper-fine particles and the distribution of particle size can be controlled.

Title: Driving force control device for vehicle
Inventor: TAMURA MINORU
IPC: B60T8/72
Filed: 1989-10-06
Abstract: PURPOSE:To ensure the stability of a vehicle and the like by inhibiting driving shaft output torque reducing control at the time of detecting the failure of a driving shaft output torque reducing means, as well as performing braking liquid pressure intensifying control in case of the accelerator stepping-in speed being more than the specified value, and stopping braking control in case of less than the specified value. CONSTITUTION:At the time of a slip being generated to a vehicle due to acceleration, the output torque of a driving shaft is reduced at a means (a), as well as braking liquid pressure is enlarged at a means (b) to avoid the slip. Hereupon, when the partial failure of the driving shaft output torque reducing means (a) is detected by a failure detecting means (e), the braking control means (b) executes pressure intensifying control to driving wheels only in case accelerator pedal stepping-in speed obtained from a detecting means (c) and an arithmetic means (d) is larger than the specified value. In case of being less than the specified value, that is, at the time of the vehicle being in low acceleration or running at constant speed, braking control is stopped. The generation of the fading phenomenon of a brake shoe can be thereby prevented while preventing the acceleration slip of the vehicle as well as ensuring the stability of the vehicle.

Filed: 1991-10-09
Abstract: PURPOSE: To produce a collagen membrane having biocompatibility and non- inflammatory properties and useful for repairing tissue as artificial implantation matter by crushing a collagen matrix to centrifugally separate the same and homogenizing the obtained precipitate to prepare paste and casting this paste before drying. CONSTITUTION: Soln. like collagen being a starting raw material is atelopeptide collagen and may contain a crosslinked collagen substance.

The crushing of the gel is mechanically performed by using, for example, a spatula and the crushed matter is centrifugally separated for about 20-30min under gravity of about 13,000×g to obtain the precipitate. By this method, a non-inflammatory collagen membrane like substance having biocompatibility can be obtained as artificial implantation matter.

Title: Electromagnet power source device
Inventor: KAWAKAMI NORIKO
IPC: G05F1/10
Filed: 1986-11-06
Abstract: PURPOSE:To provide a power source device operable without a memory, by forming a current reference from a final current command value, a current rising speed command value, an operating command, and opening a DC switch at the time when the final current command value is identical with the current reference. CONSTITUTION:A final current command value 55 and a current rising speed command value 56 are given prior to the start of operation. When an operation command is set to (1), an output of an 'and' circuit 2A becomes (1) and so an input command 54 enters a d-c switch 7. Also a clock enters a counter 21 to start the counting up operation of the counter. When a counter output 53 is enlarged enough to be identical with the final current command value 55, a comparator 22 outputs (O) and so an output of an 'AND' circuit 23A becomes (O) to supply an off command to the d-c switch 7. Subsequently the counter stops the counting operation in the counter and it outputs a fixed value. When the operation command 57 is set to (O), a resetting command enters the counter and so the current reference 53 becomes zero.

Abstract: PURPOSE:To prepare an ozone-modified carbon black suitable as an additive for coloring coatings, etc., by heating and drying a powdery carbon black, removing agglomerates and bringing it into contact with an ozone-contg. gas in a vibrational fluidized bed. CONSTITUTION:An aerosol-like carbon black formed in a reaction oven 1 is water-cooled in a cooling tower 2 and a powdery carbon black is separated and collected by means of a bag filter 3 and introduced into an air classification machine to remove foreign matters and coarse particles.

This carbon black is fed in a drying machine 10 and, after it is dried at 100 deg.C or higher, it is passed through a vibrating screen to remove carbon black agglomerates. Then the powdery carbon black is introduced on a screen 13 in a vibrational fluidized bed type ozone reactor 14 to bring it into contact with an ozone-contg. air and then, ozone is removed with dried air. It is thereby possible to prepare efficiently an ozone-modified carbon black with excellent characteristics as an additive for coloring of ink.

Title: Method of adjusting luminance of fluorescent lamp and dimmer
Inventor: DEBITSUDO ENU GIIBURAA
IPC: G09G3/18
Filed: 1988-10-20
Abstract: PURPOSE: To provide a constant light color output over an enlarged dimming range by providing a light return controller so as to monitor a light emitting output, and adjusting luminance by a variable frequency DC pulse current. CONSTITUTION: A pulse control current source 800 supplies a direct current, the current level, pulse width and wave-height of which are determined by a shunt current controller 700 concerned in frequency and a pulse width and an inductor 802. The current source 800 has a self current level adjusting function in high frequency and outputs a variable frequency DC pulse current, which is converted into an AC current by a current transformer 500, thereby adjusting luminance of a lamp 300. The current transformer 500 is driven by a current transformer driver 600. The driver 600 executes a dividing function by using 2 as a divisor, so that each of AC paths in the current transformer 500 can be activated only for 50% of a time period. Furthermore, a light return controller 900 directly monitors a light emitting output from the lamp 300 to maintain a predetermined luminance.  Consequently, a luminance apparatus 200 can exhibit the ability to provide a constant light color output over an enlarged luminance range with a relatively simple design.
