Title: Level correcting circuit for battery detecting circuit
Inventor: SATO TETSUJI
IPC: H04Q3/72
Filed: 1989-07-14
Abstract: PURPOSE:To prevent the malfunction by taking out the voltage change of a tip line or a ring line to add it to a set detection level at the time of the change of the DC voltage of the tip line or the ring line. CONSTITUTION:A reference voltage is given to one terminal of an operational amplifier 11 for battery detection by resistors R20, R21, and R22; and if the voltage of the tip line is changed in this state, the reference voltage is temporarily raised because this voltage change is inputted to the same terminal through a capacitor C5, a diode D7, and a resistor R26. Therefore, the malfunction of the operational amplifier 11 for battery detection of the ring line does not occur because of the rise of the reference voltage though the voltage change of the tip line varies the voltage of the ring line through a capacitor C and the inter line capacity. An earth detecting circuit connected to the tip line is prevented from the malfunction by the same operation.

At the same time, the vulcanization of the part also gradually proceeds. The form of the part becomes stabilized at the time when the vulcanization of the part is completed by passing through an hot air heater.

Title: Semiconductor device
Inventor: YAKIDA HIDEKI
IPC: H01L29/812
Filed: 1982-10-19
Abstract: PURPOSE:To obtain a structure suitable for high integration, by forming a Schottky gate electrode along a V-shaped groove in the direction of the width of a gate on an active region, thereby effectively reducing the Rs of an MESFET, and obtaining the high etching characteristics having excellent reproducibility and high uniformity by utilizing the anisotropic characteristics of a semiconductor substrate. CONSTITUTION:An active region 2, a source electrode 3, and a drain electrode 4 are formed on a GaAs semiconductor substrate 1. A depletion layer 9 is formed by a surface depletion layer 8 and a gate electrode 5. The increase in Rs due to the decrease in thickness of the active region between the source electrode 3 and the gate electrode 5 is effectively suppressed. Since the shape of the depletion layer 9 is formed along approximately the gate electrode 5, it is expected that the effective length of a channel becomes short in comparison with that which is not formed on a v shaped groove 6. Therefore, the Rs can be reduced, and the effective channel length can be shortened. The Vp of an MESFET is determined by the thickness of the active region directly below the gate electrode and the distribution of impurity concentration. In this constitution, wherein the Vp is directly determined by the shape of the V groove, the highly accurate Vp value is determined by the excellent reproducibility and high uniformity of the anisotropic etching.

Title: Control device for electromagnetic proportional valve
Inventor: OGAWA KIYOTAKA
IPC: F16K31/06
Filed: 1986-08-05
Abstract: PURPOSE:To improve responsibility at the time of transition as a feedback control system is kept in stable state by increasing driving current for an electromagnetic coil when deviation between the input valve of a control signal and the detected value of the driving current for the electromagnetic coil exceeds its fixed value. CONSTITUTION:A deviation detecting circuit 4 detects deviation between a control input signal A and a detecting signal B for an electromagnetic coil. A compensating circuit 5 issues a compensating signal C as long as said detected deviation is above its prescribed reference value. Consequently the input of a driving circuit 7 for the electromagnetic coil suddenly increases according to said compensating signal C, and an exciting current for the electromagnetic coil 10 increases in excellent response to a control input signal. The opening of an electromagnetic proportional valve can be therefore widened in excellent response to said input signal even in case of its sudden change.

Filed: 1987-07-23
Abstract: PURPOSE:To detect vertical and horizontal crack flaws existing on the surface of material to be detected accurately, by taking the picture of the material being detected with a camera device while scanning it obliquely with respect to the length thereof. CONSTITUTION:When a detection signal is sent from an ITV camera 9 at a time interval of DELTAT by each of scannings (1)-(3), signals are delayed by 2DELTAT and DELTAT sequentially with a delay circuit 10 and compared, one with another, by a comparator circuit 11. Then, a comparator section 13 compares the signals with a reference level signal 12 to pick up a flaw signal 14 alone. In this case, it is found that a vertical crack flaw exists somewhere between edges of the material, namely, almost at an intermediate point across the width of material 2 to be inspected. To detect a horizontal crack flaw 15, scannings (1)-(5) are performed along the length of the material 2 being detected to pick up a flaw signal contained in signals from the scannings (1)-(5) thereby enabling detection of a flaw.
