Title: Pll circuit
Inventor: SAKASHITA HIROHIKO
IPC: H04N5/06
Filed: 1990-07-03
Abstract: PURPOSE:To obtain a PLL circuit, which executes a pull-in operation even in the case of changing a horizontal frequency to be inputted, by setting a frequency dividing ratio corresponding to a signal to be inputted by a user when a medium to be inputted is changed. CONSTITUTION:This PLL circuit is composed of a phase comparator 1, programmable frequency divider 4, low-pass filter(LPF) 2 and data controlled oscillator 3, and in order to enlarge a frequency range, a horizontal synchronizing signal is inputted from this PLL circuit to a division circuit 6 so as to calculate a ratio with the oscillation frequency of the data controlled oscillator 3. The output signal of the division circuit 6 is inputted to an accumulator 7 and accumulated, the high-order output signal is inputted to a latch circuit 8, and the output signal of the latch circuit 8 is connected to the frequency divider 4 and further inputted to a comparator circuit 9. When the output signal of the comparator circuit 9, the output signal of a horizontal synchronizing pulse detector 10 and the output signal of the latch circuit 8 are lower than a certain set range or when there is no horizontal synchronizing signal, the latch circuit 8 as mentioned above is controlled so as to hold the output signal of the latch circuit 8. In respect to the input signal of an unknown horizontal frequency, first of all, the frequency dividing ratio is set and the pull-in operation is executed. Even when the horizontal frequency of the signal is fluctuated within a certain range, the pull-in operation is continued regardless of the frequency dividing ratio. Therefore, the PLL circuit can stably continue the pull-in operation.

Title: Mounting method of shape memory alloy
Inventor: HONMA MASARU
IPC: F16B1/02
Filed: 1983-09-26
Abstract: PURPOSE:To eliminate the destruction of a terminal by fatigue and mount a shape memory alloy in sufficient strength to the terminal, by mounting the shape memory alloy to be folded back and inserted being deformed from its memory shape. CONSTITUTION:A shape memory alloy 3, being mounted folding back its one end part, forms a folded part 3a and one part of a part 3b along the part 3a to be inserted into a mounting hole 2 for the shape memory alloy. The shape memory alloy 3, if its temperature reaches a certain level, tends to return to its memory shape, causing the folded part 3a to tend opening to the outside. In this way, the shape memory alloy 3 is placed in a condition it is firmly fixed to a terminal 1 by closely attaching the folded part 3a by its shape restoring force to the internal peripheral surface of the mounting hole 2 for the shape memory alloy. While here the shape memory alloy 3 is prevented from easily generating its local stress concentration because a contact part between the shape memory alloy 3 and the internal peripheral surface of its mounting hole 2 can be formed in a large area.

Title: Method for controlling mold opening pressure of injection molding machine
Inventor: ITO KATSUO
IPC: B29C45/40
Filed: 1995-06-20
Abstract: PURPOSE: To contrive not to apply an abrupt strong force for mold-opening, and prevent the generation of large shock from being generated in a moment of the removal of a molded product from a mold when the mold is opened by effecting the mold opening force pulsewise to the mold opening oil chamber of a mold clamping cylinder. CONSTITUTION: Oil pressure from an oil pressure source 17 is effected to the mold clamping oil chamber 15 of a mold clamping cylinder 12 and a mole opening oil chamber 16 through an electromagnetic change-over valve 18. An electromagnetic relief valve 19 is set in the oil chamber 16, and the oil pressure applied to the chamber 16 can be changed variously according to the conditions set up in a controller 20. Consequently, when a mold is opened, for example, if maximum pressure, pressure amplitude, and an amplitude cycle are set up in the controller 20, the mold clamping pressure can be effected pulsewise. When the time to reach the maximum pressure and the conditions to effect the pulse type mold opening pressure to the oil chamber 16 thereafter are set up in the controller 20, the mold can be opened without applying the mold opening force abruptly.

Title: Production of magnetic recording medium
Inventor: SATO SHUNICHI
IPC: G11B5/84
Filed: 1987-07-15
Abstract: PURPOSE:To enable the inexpensive formation of small-quantity articles and the easy formation of patterned magnetic recording layers by printing magnetic ink by screen printing to a base, thereby forming the magnetic recording layers. CONSTITUTION:The screen printing is executed to form the magnetic recording layer by printing the magnetic ink to the base. Namely, the magnetic ink is first printed on the base of the magnetic recording medium by the screen printing to form the magnetic recording layer in a stage 101 for printing the magnetic recording layer. The magnetic recording layer is then subjected to an orientation treatment by a permanent magnet before the magnetic ink does not dry yet right after the screen printing in a stage 102 for magnetic orientation. This magnetic recording layer is dried in a drying stage 103. The magnetic recording layer is pressurized under heating so that the magnetic recording layer has the surface smooth to the surface of the base in a stage 104 for hot pressing. This production method is thereby made to deal with the formation of a small quantity of the magnetic recording media and to the formation of the magnetic recording layers having any patterns.

Title: Software monitor circuit
Inventor: MURAI MASAO
IPC: G06F11/30
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To surely detect an abnormality of software irrelevantly to the operation state of a CPU by monitoring whether or not a process was performed in a specific period for every plural processes and detecting an abnormality of the software when any process among the plural processes is performed out of the specific period. SOLUTION: If the software of a CPU 9 becomes abnormal, the process time of the CPU 9 becomes longer than that at abnormal time and since timing outputting an address 2a from the CPU 9 to an address bus 10 is delayed, the timing of a pulse 2b from an address comparator 2 is delayed from the normal time. Since the rise timing of the output 2c of a one-shot multivibrator 5 is therefore delayed from the normal time and a time interval is generated between pulses 1c and 2c, the output signal (d) of an OR circuit 7 is temporarily a low level. In this case, since a flip-flop circuit 8 is set, the flip-flop circuit 8 outputs an alarm.
