Title: Demodulator for spread spectrum communication
Inventor: NISHI RYUZO
IPC: H04B1/7075
Filed: 1992-04-16
Abstract: PURPOSE:To enable faster initial acquisition by performing the initial acquisition by a hard decision DMF system and then performing data regeneration and DLL control on a time-division basis by a sliding system. CONSTITUTION:A sliding part 5 performs time-division product sum arithmetic by using an arrival false noise signal outputted by an A/D converter 2, three different-phase local false noise signals outputted by a local false noise signal generation part 7. Namely, product sum arithmetic for inverse spread and product sum arithmetic between two phase leading and lagging local false noise signals and arrival false signal for obtaining a signal for the DLL signal are performed on a time-division basis. Then when the output is inputted from the sliding part 5 to a data demodulation part 10, the output of the inverse speed is extracted from the time-divided signal, its polarity is decided to demodulate data, and regenerated data 11 are outputted.

Title: Work time control system
Inventor: YOSHINAGA SHINICHI
IPC: G06Q99/00
Filed: 1983-05-31
Abstract: PURPOSE:To grasp easily the work time of a checker by performing automatically the attendance control of the checker which operates a POS terminal device in parallel to the business work. CONSTITUTION:A card 1 is issued for each checker which operates a POS terminal device. When the POS terminal device is operated, the card 1 is first inserted to a magnetic card read/write part MCRW2. Then the checker operates ten-key 5 to feed a terminal number N and then pushes a change key 6. Thus a control part 3 sends the time data T0 to a write control part 8 and writes it to an address M0 of a memory 9. Then the checker pulls the card 1 out of the MCRW2 and starts a transaction with a customer. At a changing time of checkers, the checker put the card 1 into the MCRW2 and then pushes the key 6. Thus the part 3 extracts the time T0 out of the memory 9 and calculates the differential time. This differential time is written to the memory 9 as well as to the card 1.

Title: Color image forming device
Inventor: AOKI TAKAO
IPC: G03G21/10
Filed: 1984-05-14
Abstract: PURPOSE:To take a sufficient time from preexposure for ghost image erasing to primary charging to obtain pictures of good quality having a sufficient picture density, by providing an exposure means, which gives uniform exposure of near infrared rays to a photosensitive body, between a transfer means and a cleaning means. CONSTITUTION:When a preexposure light source 2 is arranged between a transfer means 9 and a cleaning means 7 as shown by a solid line, a sufficient time can be taken from preexposure to primary charging in comparison with the case where the light source 2 is arranged in a position 2' indicated by a dotted line in a device, and potential reduction after primary charging is held down to a minimum even if necessary uniform exposure is given by the preexposure light source 2. Since near infrared rays are used as the light of the preexposure light source 2, the difference of the quantity of light between a toner sticking part and a part where a toner is not stuck is reduced considerably in case of a black toner, and this difference is reduced in case of a cyan toner, a magenta toner, and a yellow toner also. Consequently, the occurrence of ghost images which are apt to occur when uniform exposure to a remaining toner image after transfer is performed is prevented effectively.

Title: Digital horizontal synchronization recovery circuit
Inventor: NAMIOKA TOSHIYUKI
IPC: H04N5/06
Filed: 1985-05-07
Abstract: PURPOSE:To obtain a horizontal synchronizing recovery signal with less jitter by using phase information finner than the unit of a sampling clock as a phase correction signal so as to detect the horizontal synchronizing signal with high accuracy in forming the horizontal synchronizing recovery signal synchronously with the horizontal synchronizing detection signal. CONSTITUTION:A digital video signal DVS is fed to a synchronizing separator circuit 12 and an inter sampling clock phase detection circuit 13. The synchronizing separator circuit 12 separates a synchronizing signal to obtain a composite synchronizing signal CS. A horizontal synchronizing detection circuit 14 obtains a horizontal synchronizing detection signal HS from the signal CS. The phase detection circuit 13 detects the phase difference between the sampling clock phiS and the leading edge of the HS to obtain a phase correction signal CSDELTAtau. The signals HS and CSDELTAtau are fed to a horizon tal phase error detection circuit 15. The detection circuit 15 forms a phase locked loop together with a horizontal loop filter 16 and a digital controlled oscillator 17 so as to detect the oscillated output phase (prescribed phase of horizontal counter output) of the oscillator 17 and the phase of the horizontal synchronizing signal in the video signal with high accuracy thereby operating the prescribed phase of the horizontal synchronizing recovery signal to be locked accurately.

Title: Piston rod quick return device of hydraulic machine
Inventor: YAMAUCHI TOSHIHIRO
IPC: B23D15/14
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To quickly return a piston rod by arranging a valve closing when pressure of a hydraulic fluid supplied to a cylinder increases and opening when pressure of the hydraulic fluid reduces, in a bypass passage. SOLUTION: When returning a piston rod of a cylinder to a former position after working a material, a motor is stopped, a solenoid valve 19 is opened, and a hydraulic fluid flowed inside the cylinder is returned little by little to an oil tank 15 through a piping hole 26 to reduce pressure inside of the cylinder. When the pressure reduces, a stepped shaft 24 is pushed down by a coil spring 25, and blocks up a piping hole 21 and a piping hole 22, and at the same time leads to the oil tank 15 through the piping hole 22 and the hole part 23. This becomes a bypass passage for returning the hydraulic fluid in the cylinder into the oil tank 15, and since a large quantity of hydraulic fluid flows in the oil tank 15 side, the piston rod of the cylinder quickly returns.

Abstract: PURPOSE:To make the controlled variable small and to shorten the time required for the seek by using a precise position control means, as well for the speed control, and also, setting a speed variation in a state that a disturbance does not exist as a profile. CONSTITUTION:A speed control signal is divided into two signals of a reference driving signal applied to a rough position control means driving circuit 5 and a precise position control means driving circuit 2, and applied to a head control system. In these signals, the signal applied to the circuit 5 becomes a reference application driving signal, and a moving speed of a head by this reference application driving signal in the case it is assumed that a disturbance such as a shock, etc., does not exist is used as a profile. By applying a speed error correction control voltage conforming to a speed deviation from this profile to the circuit 2, the moving speed of the head is controlled. Also, by a precise position control means displacement detecting means 4, displacement of a precise position control means 3 is detected, and a signal conforming to this displacement is applied to the circuit 5, becomes a speed control signal, and also, works so that the displacement amount of the means 3 becomes small.

Filed: 1994-05-11
Abstract: PURPOSE:To prevent light emitting unevenness caused by deformation of glass due to an atmospheric pressure in a flat surface type fluorescent lamp. CONSTITUTION:A front air-tight envelope 1 and a rear air-tight envelope 2 are constituted of reinforced glass. In molding, the flat surface P of the front air-tight envelope 1 is slightly deviated toward the direction contrary to an arrow A while the flat surface P of the rear air-tight envelope 2 is finely deviated toward the direction contrary to an arrow B. The front air-tight envelope 1 and the rear air-tight envelope 2 are combined, thus constituting a sealed container. Consequently, under an atmospheric pressure, the flat surface P of the front air-tight envelope 1 is deviated toward the direction of the arrow A while the flat surface P of the rear air-tight envelope 2 is deviated toward the direction of the arrow B, thereby stabilizing electric discharging because of a constant interval between the air-tight envelopes.
