Title: Electrode feed-gear in electric discharge machine
Inventor: KAWAKAMI KAZUMI
IPC: B23H7/30
Filed: 1986-10-28
Abstract: PURPOSE:To make a constitution light-weight and simple by fixing an electrode holder at the tip of a rotational shaft shaft-supported slidably in the axial direction against a frame and screw-joining a feed-screw shaft which is in parallel with the rotational shaft to a female screw formed at the frame and linking both shafts axially through a gear box. CONSTITUTION:When a feed-screw shaft 11 is rotationally driven, the feed-screw shaft 11, as it is screw-joined to a feed-female-screw Fa, can move forward and backward in its axial direction. At this time, a rotational shaft 21, too, can move forward and backward by linking with the feed-screw shaft 11 through a gear-box 30. On the other hand, the feed-screw shaft 11 and the rotational shaft 21 are made to link through a gearwheel 12, so the rotational shaft 21, too, is made to turn by the turning of the feed-screw shaft 11. As a result, the rotational shaft 21 with an electrode holder 25 fixed at the tip thereof links with the rotational drive of the feed-screw shaft 11, and can do simultaneously the feed-movement of the electrode holder 25 and its rotational movement. Accordingly, one servomotor will do as a drive-motor.

Title: Simultaneous chuck device for many pieces of work
Inventor: YAMANAKA TOYOAKI
IPC: B66C13/06
Filed: 1988-10-12
Abstract: PURPOSE:To reduce a rearrangement time by moving each nail of a chuck unit the same distance as the moved quantity of a driving rack and a tuning rack with a rack pinion, and also interposing the spring for absorbing work dimensional variation in the transfer path of the force to a driving rack. CONSTITUTION:When driving racks 38 and 44 are moved in an axis direction by actuating connecting plates 60 and 64 with an unshown cylinder, pinions 34 and 36 rotate respectively. This causes tuning racks 40 and 46 engaging with the pinions 34 and 36 to be moved in an axis direction respectively, and work is chucked with an outer nail 42 and an inner nail 44 moved. And even if variation occurs in the dimension of the work, the variation is absorbed with springs 62 and 66 interposed in the racks 38 and 34 expanded and contracted. This constitution enables a rearrangement time and labor to be reduced since the stroke of each nail can be enlarged and also the dimensional variation of the work absorbed.

Title: Moving image compression data switching device
Inventor: MORI TOSHIAKI
IPC: H04N19/85
Filed: 1993-10-14
Abstract: PURPOSE:To obtain a switching device which is capable of switching compressed and encoded moving image compression data at an arbitrary location of one- frame unit by using an inter-frame correlation. CONSTITUTION:When the input of a terminal a1 is switched to the input of a terminal a2, a switch control circuit 35 switches a switch 31 from b1 to b2 at a switching point at first. An encoder 33 compresses and encodes inputted moving image data by using an inter-frame correlation. A switch 32 is switched from c1 to c0 while the encoder 33 outputs video data before a switching and the switch 32 is switched from c0 to c2 after the encoder 33 outputs the video data after the switching. Thus, moving image compression data can be switched at an arbitrary location without disturbing video before and after the switching point.

Title: Magnetic recorder
Inventor: KAGAMI MASAYASU
IPC: G11B15/467
Filed: 1989-09-29
Abstract: PURPOSE:To correct the deviation between a recording head and a reproducing head at a high speed by providing a phase control continuation means and continuing phase control until the phase shift of the duty of a reproducing control signal at the time of recording and that at the time of reproducing gets within a specified range. CONSTITUTION:Even in the case of judging that the duty of the reproducing control signal at the time of recording and that at the time of reproducing momnentarily coincide, a phase control circuit 20 continues the phase control until the phase shift gets within the specified range. Then, the value of the reproducing control signal at 61% rising tie coincides with the value of a duty comparing area and an error value which is output signal from a phase detection circuit 24 and a pulse modulation circuit 25 becomes equal to or under a specified value. At such a time, a changeover switch signal B is outputted from an F/F 30 and a changeover switch 27 switches a switching phase control signal from a maximum control value to an ordinary value. Since the error value has allowance and a speed is stably controlled until restoring a mode to a different mode, the deviation of the recording head and the reproducing head is corrected at a high speed at the time of reproducing.

Title: Optical repeater
Inventor: IKENAGA YOSHITAKA
IPC: H04B10/079
Filed: 1989-09-29
Abstract: PURPOSE:To prevent the rise of the code error rate due to secular change by providing a means which changes the phase difference between a identification and reproducing object signal and a timing signal and a threshold voltage in accordance with the control signal from a terminal station. CONSTITUTION:When receiving a command of phase control from the terminal station, a supervisory and control circuit 7 sets a designated extent of phase delay to a phase control circuit 11 and detects the code error rate in this state and sends it as a supervisory signal to the terminal station. When receiving a command of control of a threshold voltage Vth from the terminal station, the circuit 7 outputs the designated threshold voltage Vth to a threshold control circuit 12 and detects the code error rate in such a state and sends it as a supervisory signal to the terminal station. The terminal station receives these supervisory signals to determine the extent of phase delay and the threshold voltage, which minimize the code error rate, in accordance with relations between designated extent of phase delay and threshold voltage value and sent code error rates and instructs an optical repeater to keep them. Thus, the rise of the code error rate due to secular change is prevented.

Title: Forcible feeding method for optical fiber
IPC: G02B6/00
Filed: 1992-09-25
Abstract: PURPOSE:To decrease friction resistance and to improve a forcible feeding characteristic by using a mixture composed of polyethylene (PE) and silicone resin for either of the surface of an optical fiber unit and the inside wall surface of a pipe. CONSTITUTION:At least either of the surface of the optical fiber unit 2 and the inside wall surface 1a of the pipe 1 is formed by using the mixture composed of the PE and the silicone resin, by which the-Si-H part of the silicone resin is projected on the PE surface. This-Si-H is smaller in surface tension than the-C-H of the PE and therefore, the resistance by the friction of the inside wall surface 1a of the pipe 1 for forcible feeding and the surface of the optical fiber unit 2 is decreased. At least either thereof is formed by using a mixture composed of the PE and fine powdery fluororesin as another method. Surface projections are then formed by the powdery fluororesin. Adequate surface roughness is obtd. by setting the grain size and mixing ratio of such powdery fluororesin.

Title: Vehicle slip preventive control device
Inventor: ISHIKAWA YASUTAKE
IPC: B60T8/66
Filed: 1987-10-12
Abstract: PURPOSE:To make it possible to find the slip amount of a vehicle and to control highly accurately by making it possible to infer the vehicle acceleration from the integration of the body acceleration with the actual vehicle speed immediately before the braking as the initial value when the vehicle is braked. CONSTITUTION:Although the integral value I responding to the inferred vehicle body speed is always lower than the wheel rotation speed Vw in a constant running, the initial resetting is carried out at the constant intervals, and the value I is almost equal to the actual vehicle speed V constantly. And when the braking is started, and the wheel speed Vw comes to be lower than the integral I, the integral value I is selected as the inferred vehicle speed Vi, and the slip rate S is found at a computation circuit 28 from the vehicle speed Vi and the wheel speed Vw. When the pressurizing condition is satisfied by the slip rate S and the wheel rotation acceleration by a differential circuit 14, the pressure of the braking oil is controlled to increase suddenly, maintained as it is when the pressurizing condition is not satisfied. When the depressurizing condition is satisfied next, the oil power of the braking oil is controlled to decrease, and when the condition is not satisfied, the oil pressure at the time is maintained as it is.
