IPC: H04M3/42
Filed: 1979-04-13
Abstract: PURPOSE: To transmit surely service time prediction alarm tone only from the originating station of a network, by providing a prediction alarm tone periodical transmission circuit and a release means for this circuit in the outgoing trunk of the tandem station.  
     CONSTITUTION: The TONE relay of the outgoing trunk of the tandem station transmits service time prediction alarm tone periodically. Extension subscriber SUB (A) of the A station is connected to SUB (C) of the C station by tandem connection of the B station. At this time, the marker of the B station operates the tandem relay of local trunk TRK (B1) to operate the TDM relay. Therefore, contact tdm 0  is turned off, and service prediction alarm tone is not transmitted from TRK (B1). Then, the transmission circuit of service time prediction alarm tone of the A station is operated. Thus, the transmission function of prediction alarm tone can be made efficient.

Title: Dc squid fluxmeter
Inventor: SHINADA MEGUMI
IPC: G01R33/035
Filed: 1994-03-16
Abstract: PURPOSE:To provide a DC SQUID fluxmeter in which the magnetic coupling between an input coil and a SQUID washer can be improved without giving any adverse effect on detection results. CONSTITUTION:Since the width of a slit cover 6 is increased toward the outer periphery of a SQUID washer 1 from a washer hole 1a, the stray capacitance formed between the washer 1 and the cover 6 at the outer periphery of the washer 1 increases, but, since the magnetic coupling between the washer 1 and cover 6 is small, the increase in the stray capacitance hardly gives adverse influences on detection results. On the other hand, the overlapping part of the washer 1 and cover 6 increases toward the outer periphery of the washer 1 and the amount of leakage fluxes entering the washer 1 decreases.

Filed: 1989-02-27
Abstract: PURPOSE:To remove residual toner on a heat roller sufficiently by providing a means which performs control for increasing the frequency of cleaning by increasing the rotating speed of the heat roller during a printing stop. CONSTITUTION:The control is so performed as to increase the rotating speed of the heat roll 12 during the printing stop to about 1.5 time as fast as that in printing operation. Namely, a developed continuous form is fed forcibly while clamped between the heat roller 12 and a backup roller 13. At the same time, the toner on the continuous form is fixed with the heat of the heat roller 12 and the pressure of the backup roller 13. When the printing operation is stopped and the form is released from being pressed by the heat roller 12 and backup roller 13, residual toner is obtained on the heat roller 12. The heat roller 12 is rotated during the printing stop, the residual toner on the heat roller 12 is removed by a 1st cleaning roller 14, and the residual toner which is transferred to the 1st cleaning roller 14 is removed by the 2nd cleaning roller 15. Consequently, the residual toner on the heat roller can be removed sufficiently.

Title: Antiskid control device
Inventor: YASUNO YOSHIKI
IPC: B60T8/1761
Filed: 1988-02-29
Abstract: PURPOSE:To estimate an adequate car body speed by adding an offset amount, which increases oppositely to a decrease of the estimated car body speed, to an absolute value of a longitudinal acceleration detection value in case of esti mating the car body speed by the longitudinal acceleration detection value at the time of detecting a lock tendency of a wheel. CONSTITUTION:A car body speed calculating means uses a maximum value in each of the wheel speeds from a wheel speed detecting means serving as the initial value, adding an offset amount, which is increased as an estimated car body speed decreases, by an offset amount supply means to an absolute value of longitudinal acceleration from a longitudinal acceleration sensor, and integrating the added value, the car body speed is estimated. An actuator control means, being based on the estimated car body speed and each wheel speed, outputs an instruction signal in accordance with a braking condition individually to each actuator, controlling pressure of a braking cylinder of each wheel. In this way, even when an error, deflected to a no-brake side, is contained in a longitudinal acceleration detection value, the error can be compensated in accordance with the estimated car body speed, and more accurately obtaining the estimated car body speed, a no-brake condition can be surely avoided.

IPC: G03F1/20
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a high precision shape of an opening irrespective of opening size by exposing the periphery of the opening by a predetermined width without exposing the interior of the opening, when forming a larger opening than a predetermined opening in a resist. SOLUTION: After a resist 62 has been coated over a silicon substrate 61, the periphery of an opening is exposed by a predetermined width in exposing a large opening. Next, by having it developed, a hole 72 is bored by removing the exposed portion 71 of the resist 62. Subsequently, an opening 73 is bored similar to the conventional cases by etching the hole portion 72 of the silicon substrate 61 by means of plasma etching or wet etching. Thereby, an opening is formed along outside of the exposed portion 71 by removing an inner portion of each of a silicon substrate 61b and a resist 62b. Since the exposed portion 71 is narrow and the etching is performed at the same rate as a small opening, an opening 73 with a desired width can be formed by setting the same etching condition as that for a small opening.
