Title: Control method for channel assignment in loop communication system
Inventor: TAKAHASHI MASAHIRO
IPC: G06F13/00
Filed: 1980-02-08
Abstract: PURPOSE:To improve efficiency of circuit utilization by increasing or decreasing the number of time slots for circuit switching according to request for using the time slot for circuit switching channel from each station. CONSTITUTION:A connection/disconnection request receiving register 32 of a control station receives connection/disconnection request field and whether it is request for connection or request for disconnection. In case of request for connection, it checks whether the station indicated by the receiving station address DA is already in communication with other station or not, and if not, sets permission for use through an O/I inserter 34, and sets ''1'' in the sending address field corresponding to the sending station address SA. Like this, the number of time slots for circuit switching is increased or decreased according to demand for use of time slot for circuit switching channel from each station. Thus efficiency of circuit utilization can be improved by responding flexibly to load fluctuation of channels for circuit switching and bucket switching.

Filed: 1989-01-24
Abstract: PURPOSE:To improve a working efficiency by a method wherein two or more holes shaped differently from each other are provided in a molded resin part of an integrated circuit element so that they pierce the resin part from the surface to the rear, while projections to be fitted in said holes respectively are provided in a part of a socket. CONSTITUTION:When projections 101 and 102 to be fitted in the above-mentioned holes 3 and 4 are provided beforehand on a socket 100 for testing, an integrated circuit element is fixed in two places. Consequently, a part 1 of a lead 2 is fixed and the lead 2 is brought into reliable contact with a metal terminal 200 for testing. If the holes 3 and 4 are reversed in positions, the aforesaid projections are not fitted in said holes since the holes are shaped differently from each other, and accordingly the mounting direction at the time when the aforesaid integrated circuit element is mounted on the socket 100 for testing is determined. In this constitution, an assembling process is not passed through twice as usual, and a product is obtained when processes of selection and BT screening are completed after removal of an outer frame and leg-bending formation of the lead are conducted in the assembling process. According to this constitution, a wasteful process is dispensed with and a working efficiency is improved.

Filed: 1990-01-25
Abstract: PURPOSE:To shorten the axial length of a deflecting yoke by disposing a magnetic body piece in an envelope in which a deflecting magnetic field is present, and working the deflecting magnetic field onto electron beams. CONSTITUTION:A miniature cathode-ray tube 1 has an electron gun 3 in the neck part 2a of an envelope 2 and a phosphor layer 4 on the inner surface of the face panel part 2b thereof. A permanent magnet 5 forms a magnetic focusing means giving focusing effect to electron beams together with magnetic pole pieces 6, 7. A deflecting yoke 13 for generating a deflecting magnetic field and a pair of ring magnets 14, 15 for centering are installed onto the outer circumferential surface of the envelope 2, and the yoke 13 has a gap (g) with the magnetic focusing means. The relative opposed end surfaces of magnetic body pieces 10, 11 are extended toward the electron gun 3 side phosphor layer 4. Thus, the main part of the horizontal deflecting magnetic field from the yoke 13 is focused on both the wing parts of the relative opposed end surfaces. As the focused and enhanced horizontal deflecting magnetic field is worked onto electron beams, the axial length of the yoke 13 can be shortened.

Patent JP-H01193423-A (JP)
Title: Shock absorber
Inventor: MITO TOSHIYASU
IPC: B60G17/08
Filed: 1988-01-28
Abstract: PURPOSE:To make the dispersion of a damping force less by providing a piston having a check valve and a passage mutually communicating the first and the second liquid, and moreover providing the passage with a throttle valve, a free piston to partition the inside of the passage into the third liquid chamber and a gas chamber, and a check valve to check a flow from the second liquid chamber. CONSTITUTION:A shock alsorber has a compensating vessel 22 for an increase and a decrease in the volume of the second liquid chamber 48, and liquid passes through a common throttle valve 104 at the time of the extending and shortening of a piston rod 14, and thereby generates damping force. Thus only the throttle valve 104 requires its own accurate machining, and a primary facter causing the dispersion of machining accuracy can therefore be sharply reduced to make the dispersion of the damping force less. In addition, since in the case of a piston speed kept constant during the extending and shortening of the piston rod, the damping force generated then is given by a function of the ratio of raising a pressure receiving area during the extending and shortening of the piston rod to the third power to raising the orifice area of the throttle valve to the second power, properly selecting the dimensions of a piston 16 and of the piston rod 14 can make the damping forces the same in their strength during the extending and shortening of the piston rod.

Title: Injector driving device
Inventor: UTORO HIROTSUGU

Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion of an injection characteristic in an injector driving device recovering to accumulate flyback energy of a solenoid valve to supply it to an injector. SOLUTION: When valve closing driving of a PCV is completed, both end voltage of a capacitor and battery voltage are detected after standing by during the time of the capacitor being charged with a flyback current flowing due to cutoff of current application to the PCV (for waiting time Tw) (S110-S130). In case of both end voltage of the capacitor not reaching full charge (118V), current flowing time Ton required to generate such a flyback current to charge the capacitor full, to the PCV is set on the basis of differential voltage, and boosting switching for applying a current to the PCV and cutting off is performed according to the current flowing time Ton (S140-S200).  The boosting switching is repeatedly executed while changing the setting of current flowing time according to the differential voltage until both end voltage of the capacitor reaches full charge as a result of this boosting switching.
