Abstract: PURPOSE:To enable a communication line to switch not through a power supply of opposing party at a remote control, by charging a capacitor of an opposing station with a DC current transmitted on a spare line and operatng a relay with a discharge current of the capacitor when this current is stopped. CONSTITUTION:In the communicaton of a communication equipment EQ through a line A, a DC current, + for a tip T and - for a ring R is supplied from a station with the maintenance personnel to a spare line B. The DC current charges a capacitor C1 via a switching circuit rl4, diodes D1 and D3 and a rl3 and flows to a diode D2 and a resistor R1 to turn off a transistor TR1. When the changeover from the line A to the line B due to noise, the DC current to the line B is stopped. The D2 is nonconductive, the TR1 turns on, the charge in the C1 is discharged via a latch relay RL to energize the RL to switch circuits rl1- rl4, and the equipment EQ makes communication through the line B. Next, the line A is taken as a spare and a DC current flows to the line A by keeping the tip T as + and the ring R as - and a capacitor C2 is charged via diodes D4 and D6.

Title: Holding device for inner circumferential cutting edge type blade
Inventor: SAWAFUJI SUSUMU
IPC: B23C5/22
Filed: 1987-03-31
Abstract: PURPOSE:To aim at a check of rotational variations due to the runout of a blade and chips, etc., by erecting each support member, supporting tension heads installed in holding the inner circumferential cutting edge type blade in between and being displaceable in the radial direction, in quadrisectional spots in the circumference of the top of a rotary plate. CONSTITUTION:A top ring 12 is mounted on a tension ring 11, holding a blade 14 in between and clamping it, while the blade 14 is pressed by a tap bolt, and the required tension is giving by degrees. And, when an (x) direction is larger in tensile strength than a (y) direction, if bolt pressing force at the (x) direction side is made larger than that in the (y) direction, tension at the (x) direction side grows larger than the (y) direction so that reaction also becomes larger at the (x) direction, whereby such a stress that an (x) direction diameter of tension heads 13 becomes shorter than a (y) direction one. When this stress load is larger than rigidity of the head 13, the head is displaced to the short diameter at the (x) direction side but the (y) direction side to a long diameter, respectively, therefore this displacement is spread to each support member 15, but since the support member is displaced in the radial direction of a rotary plate, it absorbs this diametral displacement. Consequently, height displacement also will not cause any blade runout in substance. In addition, chips or the like is quickly discharged out of a clearance between support members.

Title: Preparation of gas rich in methane
Inventor: TOIDA TSUTOMU
IPC: C07C9/04
Filed: 1979-06-22
Abstract: PURPOSE: To obtain conc. methane, by removing steam prtly from a reformed gas from an adiabatic reactor comprising only one reaction zone in the methanization of a hydrocarbon, and by feeding the rest cooled to such an extent as not to condense steam to the reactor.  
     CONSTITUTION: A ≥2C hydrocarbon is reformed with steam adiabatically at 350W 550°C to give a reformed gas comprising methane, H 2 , CO, CO 2  and steam. In feeding the gas to a methanization zone, steam is partly removed to reduce the dew point of the gas, and the gas is cooled to such an extent as not to condense the remaining steam. The cooled gas is then fed to one adiabatic methanization zone to give a gas rich in methane free from the steam and CO 2 . The reactor may comprise only one catalyst bed, and is very simple in construction because a built-in heat exchange surface is unnecessary. The methane concentration can be increased by decrease in partial pressure of steam with decreasing feed temperature.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To secure sufficient tape takeup torque and to surely take up a magnetic tape by switching ordinary tape drive by a reel stand to capstan drive when a tape takeup load is increased in the fast forward or rewind mode of magnetic tape. SOLUTION: At the time of fast forward/rewind mode, a rotation detecting signal frequency measuring part 11 outputs a frequency measuring signal by monitoring the outputs of reel driving motor 1, frequency generator 4 for detecting the rotation number of reel stand and supply reel side and takeup reel side rotation sensors 5 and 6. When the frequency measuring signal gets lower than the frequency value in a reference frequency value storage part 12, a speed down discriminating part 13 judges the increase of reel driving load, outputs an abnormal discriminating signal and changes a mechanism device into high-speed search mode. Thus, the magnetic tape can be surely taken up and cost reduction can be attained by suppressing the reel driving motor 1 and a power supply circuit 2 for reel driving motor drive into medium capacitances.

Title: Impact relaxing device within bumper
Inventor: KANEKO TOSHIAKI
IPC: B60R19/18
Filed: 1992-02-29
Abstract: PURPOSE:To prevent a bumper front plate from being deformed by relaxing impact force applied to the bumper front plate of an automobile by means of electromagnets. CONSTITUTION:A front and a rear electromagnet mounting member 9 and 11 are mounted onto a bumper front plate and a front side member 4 respectively with a distance spaced in the back side of the bumper front plate 7, a plural number of electromagnets 12 are mounted onto the front and rear electromagnet mounting members 9 and 11 while being faced to each other, a collision detector 14 is interposed between the electromagnets over the front electromagnet mounting member 9, and a timer means is provided for the collision detector 14 in series. When an impact force is applied to the bumper front plate 7, the collision detector 14 is operated. This constitution thereby allows current to flow in the respective electromagnets 12, and also allows repulsive force to be produced, so that impact force is thereby relaxed. The actuation of the timer means permits the electromagnets 12 to be active only in a specified period of time. Even if a force is locally applied to the bumper front plate 7, deformation can be prevented because the repulsive force in place becomes great. Since a plural number of electromagnets 12 are arranged to distribute an impact force to a car body, the bumper front plate 7 can be restored to its initial shape, so that the appearance is thereby improved.

Title: Glass ceramic circuit board and manufacture thereof
Inventor: KAMEZAKI HIROSHI
IPC: H01L23/15
Filed: 1991-04-12
Abstract: PURPOSE:To eliminate the separation of a signal layer from a strengthening layer by substituting a porous glass powder for a portion of a glass powder. CONSTITUTION:In order to reduce the dielectric constant of a signal layer 8, a green sheet is formed which consists mainly of a ceramic powder, a glass powder, and hollow miniature glass spheres. However, the particle diameter of the hollow miniature glass spheres is large and a spherical shape is created and because of the hollow state, the contraction ratio is small even in sintering temperatures. On the other hand, the sintering contraction ratio of the reinforcing layer 9, which is layered on both sides of the signal layer 8 and consists mainly of a ceramic powder and a glass powder, is large. As a result, the sintering contraction ratio is increased and by having it match the contraction ratio of the strengthening layer 9, it is possible to eliminate separation from the board.

Abstract: PURPOSE:To accurately move a lens along a track and to obtain an image of good quality by executing an adaptive control in accordance with an overall condition of characteristics on the track, an action speed and a mutual relation between plural lens groups on the track. CONSTITUTION:The signal of an external control indicator 42 is detected by an action kind detector 45, an acting direction detector 46 and an action speed detector 47 so as to obtain the action kind, the acting direction and the action speed. An object distance and a focal distance are obtained based on the positions of a 2nd lens group 32, a 3rd lens group 33 and a 4th lens group 34 detected by position detectors 36 and 37. The moving extent is calculated based on the overall condition constituted of the characteristics on the track, the action speed and the mutual relation between plural lens groups on the track obtained in such a way, and then, the adaptive control is executed. And in order to process for a practical use, the variation of the focal distance of respective lens groups, or of the object distance is obtained based on fuzzy inference by applying fuzzy rules having the characteristics on the track and the action speed as an antecedent part and having the focal distance, or the object distance obtained after the lenses are moved as a consequent part.
