Title: Frequency-error detecting apparatus
Inventor: HORIGUCHI SHINOBU
IPC: G06F11/00
Filed: 1990-10-25
Abstract: PURPOSE:To omit a clock generating device and to prevent the generation of noises by issuing an alarm when the steady-state signal from a first monostable multivibrator is not detected for a specified time or when the steady- state signal from a second monostable multivibrator is detected. CONSTITUTION:When an input signal is higher than an upper-limit frequency, the output signal level of a first monostable multivibrator 21 is kept at an inverted level. Therefore, a signal processing means 40 cannot detect the steady- state signal of the multivibrator 21 after the elapse of the specified time, and an alarm is transmitted. When the input signal is located between the upper-limit frequency and the lower-limit frequency, the first monostable multivibrator 21 repeats the inverted level and the steady-state level, and a second monostable multivibrator 31 keeps the inverted level. Therefore, the signal processing means 40 does not output the alarm. When the input signal is lower than the lower- limit frequency, the second monostable multivibrator 31 alternately repeats the inverted level and the steady-state level. The processing means 40 detects the steady-state signal of the multivibrator 31 and transmits the alarm.

Title: Controller of stepping motor
Inventor: SHOJI TAKASHI
IPC: H02P8/32
Filed: 1988-11-15
Abstract: PURPOSE:To save power and to enable highly accurate position control by applying minimum necessary hold torque and switching to holding through detent torque at the stage when it is allowed. CONSTITUTION:When a CPU produces a drive pulse from its output port P0, Q1 is turned ON to turn Q5 ON and Q8 is turned ON by the drive pulse fed from P0, and thereby current flows through a coil L1 from phi1 to phi2 thus exciting the coil L1. When the CPU judges that the level has varied, a counter (c) is set to zero count. The counter (c) is incremented upon elapse of 0.1msec and checked whether the count thereof has reached to 30, and if the count has not reached to 30 input to P4 is checked and variation of level is checked. When this operation is repeated, a section where current vibrating with slightly shorter period than vibration period 3msec and with predetermined dead level is detected. Then power conduction to a motor is stopped to finished excitation of the motor and the rotor is held by means of detent torque.

Abstract: PROBLEM TO BE SOLVED: To prevent the narrowing of a low melting point fusible alloy piece to keep its resistance at a predetermined value and to enhance its working accuracy by welding the low melting point fusible alloy piece mounted straddling between electrodes to the electrodes which are formed opposite to each other on an insulating board with flux applied to their upper surfaces by means of heating without pressure. SOLUTION: A low melting point fusible alloy piece 4 is mounted straddling between film-like electrodes 2, 2 which are formed on an insulating board 1 such as a ceramic plate or the like by the application of electrode forming paste by means of screen printing or the like and by its baking and of which upper surfaces are thinly coated with flux 3 such as a rosin. It is fused in a heating furnace or by being heated without pressure by the contact of a heated plate of which contact pressure is substantially zero, and thereafter cooled so that it is fixed to the board. The oxide film having a predetermined degree of oxidation that is formed on the surface of the low melting point fusible alloy piece 4 is formed into a bag-like shape in fusing, and is never flowingly deformed so that its initial shape is retained.  Because the flux 3 to fuse the oxidation film is applied in a small thickness the wetting and expansion of the fused metal is restrained slight by an interfacial action.

In this case, a binary value Ak ' to be allocated to each sample (k)is determined by comparing the arithmetic sum and the threshold of two adjacent sample values. Thus, correct binary values can automatically be extracted.

Title: Stamper and die for molding synthetic resin substrate
Inventor: FUJINAWA HIROYA
IPC: B29C33/00
Filed: 1988-11-15
Abstract: PURPOSE:To prevent the movement of a stamper positively thereby to improve the service life of the stamper and the quality of a substrate by providing a part to be engaged with an engaging part at the side of a die in a direction along the surface of a cavity forming part. CONSTITUTION:When a stamper 20 is mounted in a movable core 14 of a die 10 thereby to form a substrate, a to-be-engaged part 30 of the stamper 20 is engaged with an engaging part 31 of the die 10. Therefore, the stamper 20 is prevented from being rotated over the surface of the movable core 14. Accordingly, it becomes unnecessary to strongly press the stamper so as to prevent the movement thereof, whereby the stamper 20 can be prevented from being deformed by the pressing force, thermal expansion or shrinkage. The stamper 20 can be positively engaged with the die 10 by the relative engagement between the to-be-engaged part 30 of the former and the engaging part 31 of the latter. Even when a resin is moved by a high injection pressure, the stamper 20 is not moved at all. Accordingly, the surface of the movable core 14 is never defective, and resin pressure allows neither transfer of defect to the stamper 20 nor deformation of the stamper.
