Title: Method of executing earthquakeproof tunnel
Inventor: ONO KOICHI
IPC: E21D11/04
Filed: 1987-06-30
Abstract: PURPOSE: To prevent the breakage of a longitudinally-directional coupling by interposing a high strength, low rigid plastic-made earthquake resistant washer between a nut screwed in the coupling bolt of a longitudinal direction coupling and a coupling plate having a coupling bolt pierced therethrough. CONSTITUTION: When a buried tunnel is executed, a number of divisional parts are made, and adjacent segments 1, 1 are formed via longitudinal direction couplings 2, 2. Furthermore, each ring-shaped, high strength, low rigid plastic earthquake resistant washer 7 is put from the tip end of a coupling plates 3, 3 of couplings 2, 2. The coupling plates 3, 3 are fastened to each other with predetermined force by a nut screwed from the tip end of the bolt. Therefore, even in the case where excessive force may exert the couplings 3, 3 by an earthquake, the coupling plates 3, 3 can be prevented from being broken through deformative absorption of the washer 7.

Title: Position control device
Inventor: KAMIIDE TAKAO
IPC: G05D3/12
Filed: 1979-12-17
Abstract: PURPOSE: To ensure an extremely high-accuracy positioning even with the effect of disturbance given during the control, by detecting the fact that the control subject enters the prescribed error range and then delivering again the position set value to give the same stop control.  
     CONSTITUTION: The signal 1 delivered from the output terminal 0 of the sequence counter 1 is applied to the position setting device 2 via the OR circuit OR1 and in the initial state before the control of positioning of the control subject 5. The device 2 delivers the previous set position command signal ES with application of the signal 1. On the other hand, the position detector 6 detects the present position of the subject 5 and then delivers the corresponding position signal ES. Then the driving circuit 3 drives the actuator 4 in response to the deviation signal S of the signals ES and eS, thus carrying out a position control of the subject 5 such as a hydraulic cylinder or the like. In sucy way, the fact that the subject 5 enters the prescribed error range is detected and then the position set value is delivered again to perform the same stop control. As a result, an extremely high-accuracy control is possible for positioning even with the effect of disturbance.

IPC: B23F15/02
Filed: 1991-07-04
Abstract: PURPOSE:To make engagement smooth by engaging a pair of non-circular gear rotating bodies with each other, driving one rotating body, and applying abrasive action onto the engaged gear teeth to correct it into a form with which the gears can rotate while maintaining a shaft-to-shaft distance. CONSTITUTION:Rotating body materials 1 and 2 of drive gears which need correction are fitted closely to fix onto a rotating shaft 17 of a shaft mounting member 18 for fixing one rotating body material 1 to a base 19 at a specified engagement position.

When a rotating torque is applied to the rotating shaft 17 of the rotating body material 1 through a rotating gear 20, the rotating body 2 is pressed against the rotating body 1 by a spiral shaft 28. In this case, the center-to-center distance of both rotating body materials 1 and 2 is set slightly smaller than the designed dimension. Then the follower side rotating body material 2 is rotated by the drive side rotating body material 1 to grind it with abrasives.

Title: Image scanner device
Inventor: TANIMURA MASAHITO
IPC: H04N1/405
Filed: 1985-07-25
Abstract: PURPOSE:To make an image scanner device handling the presence/absence of white/black levels only without expression of an intermediate density express a pseudo multi-value with an inexpensive means by adopting the constitution that a noise signal is applied to an analog signal output from an optical read section and the result is compared with a threshold voltage. CONSTITUTION:An analog signal representing the density of a graphic received by a comparator 5 is the sum between a voltage division of an output of a white noise generator 7 by a variable resistor 8 and an output of a CCD image sensor 3 by an adder 9 and the sum changes irregularly timewise with respect to the substantial output of the CCD image sensor 3. In comparing the output with a threshold voltage decided by a variable resistor 6, since the probability of the output with logical '1' of the comparator 5 is increased as the output of the adder 9 increases, that is, the output of the CCD image sensor 3 increases, the frequency of output being logical '1' is increased according to the density of the inputted graphic and the intermediate tone is expressed in a pseudo way. In this case, the variable resistor 6 adjusts the density and the variable resistor 8 adjusts the contrast.

Title: Flux dipping device
Inventor: TOOYAMA SEIICHI
IPC: H01M50/541
Filed: 1978-12-27
Abstract: PURPOSE: To keep the flux level in the dipping bath constantly and enhance the weldability, by moving a piston of specified structure vertically between the dipping bath and the reservoir, and feeding the flux to the dipping bath in upper part through a flexible pipe.  
     CONSTITUTION: Flux liquid 2 is poured into an upper chamber 3a. The liquid 2 flows into a lower chamber 3b from a hole 8 in a piston 5 through the piston 5. When the liquid level rises to a certain level in the upper chamber 3a, charge of the liquid 2 is stopped. In this state, when the piston 5 is moved vertically, the liquid 2 passes through a flexible pipe 4 to be pushed up into a dipping bath 1. When the flux liquid level in the bath 1 exceeds the height of the piston 5 projecting into the bath 1, the liquid 2 returns to a reservoir 3 through the piston 5, so that the liquid 2 level is always kept constant by operation of the piston 5. Therefore, when the position of the pole plate group to be coated with the liquid 2 is properly adjusted to the position of the bath 1 when the piston 5 is raised to the highest position, always a constant volume of liquid 2 may be applied.

Abstract: PURPOSE:To decrease the power consumption and to have communication of high quality with a small change of frequency, by making an intermittent locking operation of a PLL circuit performed in response to the transmitting/receiving operation of a radio communication device. CONSTITUTION:The number of divisions is switched between the transmitting mode and the receiving mode for a frequency divider 3 of a frequency synthesizer 10 in accordance with the operation of a press-to-talk switch 25.

Furthermore the switches 11 and 12 are closed periodically or for a prescribed period when the contact 15 is closed by means of a timer 14. Thus a loop of the main body 6 of a PLL circuit is closed, and at the same time the output of a power source 7 is supplied to lock the oscillating frequency of a voltage control oscillator 2. Then the oscillating frequency is corrected and then locked again when the switches are closed next.

Filed: 1980-11-21
Abstract: PURPOSE: A thermosetting resin composition having improved bonding strength and durability, by curing a peroxide-curing type high-molecular resin composition in the presence of an isocyanato-terminated unsaturated compound.  
     CONSTITUTION: A composition of a high-molecular resin having unsaturated bonds in the molecule and being curable with a peroxide is mixed with an unsaturated compound having end groups partially terminated with isocyanato groups and the mixture is cured. Curing of the thermosetting resin composition involves co-crosslinking between the double bonds of the low-molecular unsaturated resin having an isocyanato group on one end and an unsaturated bond on the other end and the double bonds of the high-molecular unsaturated resin in the presence of a peroxide. Moreover, even after the completion of this reaction, the composition still contains isocyanato groups, so that a curing reaction can further proceed by the moisture contained in the resin composition or in the atmosphere. This can provides improved durability, improved strength of adhesive failure and outstanding bonding strength.
