Title: Focus lens device
Inventor: FUKUSHIMA TETSUO
IPC: G02B7/04
Filed: 1985-10-18
Abstract: PURPOSE:To reduce the torque by moving ball bodies supported in recessed parts of a focus lens frame along a female helicoid screw by rotation of the focus lens frame to feed out the focus lens frame in the direction of the optical axis of a lens. CONSTITUTION:A focus lens frame 1 is rotated manually or rotated and driven by a motor to move ball bodies 3 supported in recessed parts 1a of the focus lens frame 1 along a female helicoid screw 2a and the focus lens frame 1 moves the lens forward or backward in the direction of an optical axis A-A', thereby focusing the lens. Since ball bodies 3 are brought into contact with the female halicoid screw 2a at points in this case, the force of friction is less generated and the torque is reduced.

Title: Carrier recovery circuit
Inventor: IWAMATSU TAKANORI
IPC: H04L27/00
Filed: 1987-09-19
Abstract: PURPOSE:To surely establish the synchronization of a recovering carrier in a short time by detecting the rotation of a carrier for only the outside part of the flat plane of a reference phase before the recovering carrier is pulled in the flat plane of the reference phase. CONSTITUTION:A pre-pull-in phase detecting means 3 which divides the flat plane of the reference phase into the outside part and an inside part and can obtain information representing the rotational direction of the phase of the carrier at the outside part based on a demodulation signal is provided. And the output of the pre-pull-in phase detecting means 3 is inputted to a phase synchronization means 2 by a selection means 6 corresponding to the output of an error detecting means 5 when a bit error rate exceeds a prescribed value. Thus, before the carrier is pulled in, the rotational direction of the carrier is detected only for the outside part on the flat plane of the reference phase, and the detection is not performed by the interval of signal points. In such a way, the detection can be performed easily, and a frequency possible to be pulled in is extended, and a pull-in time can be shortened.

IPC: F23K5/04
Filed: 1989-09-08
Abstract: PURPOSE:To prevent oil dripping by forming an absorption chamber which comprises a movable partition plate and oil resistant sponge on an electromagnetic cylinder. CONSTITUTION:During combustion when electric power is applied to an electromagnetic coil 1 so that an electromagnet 2 may be magnetized, a piston 5 in a cylinder 4 is absorbed to the electromagnet against the pressure of a spring 3.

A power source supply detecting part 13 is connected to the transmission pathes 33 and 34 and by its information, a control part 12 switches and controls a change-over switch 11. When the switching part of the same transmission path of the change-over switch 11 of the main equipment 1 and a change over switch 21 of the key telephone set 2 is in an on-condition, the current is supplied to the key telephone set 2. In the time zone in which the call quantity is small, the server of the key telephone set 2 switches the change-over switch 21 and interrupts the supply of the current. When the server of the key telephone set 2 desires a call in such a condition, the change-over switch is switched.

A slip rate is calculated in accordance with the thus calculated values, and discrimination is made on whether this slip rate S is a desired slip rate or not. When the slip rate S is not equal to the desired slip rate upon starting, the CPU calculates the deviation DELTAS therebetween, and also calculates the data DELTAtheta of correction amount for the throttle opening in accordance with the deviation. Further, the CPU issues, in accordance with this correction amount data DELTAtheta, an air amount control signal 220 for controlling the output torque of the engine.

Abstract: PURPOSE:To easily adjust offset voltage erasing by erasing the offset voltage of a common error amplifier for controlling respective transistors(TRs) correspondingly to a current set point by an offset voltage erasing value adjusted by an offset voltage erasing circuit. CONSTITUTION:A resistor circuit net 2 detects the average value of currents flowing into respective TRs 1-1 to 1-n as a voltage value and respective error amplifiers 3-1 to 3-n control respective TRs 1-1 to 1-n correspondingly to differences between the current detection values of respective TRs 1-1 to 1-n and the average value to average current charge. The offset voltage erasing circuit 4 adds the average value to the offset voltage erasing value and outputs the added value and the common error amplifier 5 adds an output signal corresponding to the difference between the output of the circuit 4 and the current set point to the output signals of the error amplifiers 3-1 to 3-n respectively through resistors to control respective TRs 1-1 to 1-n. Since the circuit 4 can be used in common independently of the number of error amplifiers, the offset voltage erasing position can be restricted only to one position and the offset voltage erasing can easily be adjusted.

Title: Sealing device
Inventor: MITSUMARU MICHITOSHI
IPC: F16J15/18
Filed: 1991-09-13
Abstract: PURPOSE:To improve the extent of sealing performance at the time of pressure load by unitizing a first ring with a pressing part for pressing a seal ring to an outer member, while dividing the first ring into two axial parts so insertably between two backup rings. CONSTITUTION:A first ring 10 is solidly formed with a pressing part 13 at the outer circumferential side central part, and the contact parts 10a, 10b with a groove side of the first ring 10 are axially divided in making this first ring 10 insertable in space between two backup rings 11 and 12. When pressure oil has flowed into a sealing device 3 at time of pressure load, even if the pressing part 13, pressing a seal ring 14 to an outer member 4, tries to shift, this movement is checked by the first ring 10, so this pressing part 13 is not largely moved in the axial direction. Accordingly, such a force as pressing the seal ring 14 to the outer member 4 is stabilized, thus sealing performance at time of the pressure load is improved.
