Title: Method for applying overlay cover and device therefor
Inventor: KRALLER CHRISTIAN
IPC: B29C51/08
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To fully realize the plasticization of a thermoplastic material without heating so high as to affect adversely by a method wherein a carrier part is pre-heated at the start of heat treatment up to a temperature level, which lies between a usable temperature for a long period of time without accompanying a mechanical stress and the plasticizing temperature of the thermoplastic material. SOLUTION: On one hand, the amount of energy taken in for plasticizing the surface portion of a carrier part 1 must be as much as possible for plasticizing in a short period of time and this is the reason why the part is heated up to a pre-heating temperature level before its impulse heating. On the other hand, a too high pre-heating temperature is not preferable for, first of all, excluding the thermal damage of the part and, secondly, maintaining enough rigidity to the shape of the part for allowing to adhere a cover to the part. Accordingly, the part is heated up to the pre-heating temperature level, which lies within a usable temperature for a mechanical stress toward a thermoplastic material and is lower than the plasticizing temperature of the thermoplastic material.

Title: Production of rotary transformer
Inventor: INCHI TOSHIO
IPC: G11B5/02
Filed: 1984-10-01
Abstract: PURPOSE:To prevent the deformation or warp on the material at the process after the injection molding by specifying the volume ratio of the binder in the blank material for the core element. CONSTITUTION:The soft ferrite magnetic powder is combined with binder and is heat-treated and kneaded to be formed into slurry. At this time, the ratio of the binder is specified as 15-50vol%. Then, this blank material is pressed into the mold, and the core elements 1 and 2 having coil grooves 1a, 2a and coil lead-out grooves 1b, 2b are injection-molded. Then, the core elements are heated upto 300-500 deg.C for degreasing. Then, the core elements after the degreasing are sintered at the temperature 1,000-1,400 deg.C to provide the stator side core 1 and roter side core 2. For the cores 1 and 2 thus obtained, their degree of filling of the blank material in the mold is uniformized since the slurry-state blank material with superior fluidity has been injected into the mold, preventing deformation or warp in the process thereafter. Therefore, the surface machining thereof can be omitted after the sintering.

Title: Ultrasonic vibrator and ultrasonic motor
Inventor: IWAO NAOTO
IPC: H02N2/00
Filed: 1989-08-07
Abstract: PURPOSE:To increase the movable range of an ultrasonic vibrator by mounting an electromechanical converter for exciting a substantially elliptical vibration, a power source for applying an electric signal, and a circuit for controlling the power source at predetermined positions of an elastic element. CONSTITUTION:A power source 31 and a controller 41 are mounted at predetermined positions near an elastic element 21, and respectively electrically connected to first and second piezoelectric elements 22 and 23a, 23b. When an AC voltage is applied to the element 22, the element 21 is resonated in a secondary bending vibration mode. When an AC voltage is applied to the elements 23a, 23b, the element 21 is vibrated in a primary vertical vibration mode. The vibrations of the two directions are combined to generate a substantially elliptical vibration at a predetermined position to vary a frequency variable oscillator 34 of the controller 41 and a phase shifter 42 to arbitrarily form a vibrating trace of the elliptical vibration.

Title: Testing of integrated circuit
Inventor: KATO HIDEAKI
IPC: H01L21/66
Filed: 1987-08-19
Abstract: PURPOSE:To enable the compression of a test pattern, by employing an FF within an IC which can be set in combination of signals unavailable in actual use to get tested or reset by combining an output of the FF and an input in no way affecting a portion as object to be tested. CONSTITUTION:A fixed time length '1' is applied to a terminal F for a fixed time and then, '0' to a circuit to initialize it. When the terminal F is down to '0', a signal is applied to terminals G and H to turn a line L6 to '1' through an FF9. Then, '0' is applied to a terminal B and '1' to terminals D and E. A clock input is applied to terminals A and C separately for a frequency dividing circuit 1 and a function block 4. Under such a condition, a clock input from the terminal C enters the block 4, an output of which can be observed directly at a terminal 1. Moreover, a clock route can be tested by applying '0' to the terminal D. In this case, before the applying of '0' to the terminal D, a signal input is given to the terminal B to initialize the circuit 1 thereby enabling compression of a test pattern with a phase matching in the switching of a clock.

Title: Dual safety circuit for combustion control device
Inventor: HAYATA YOSHIKI
IPC: F23N5/24
Filed: 1985-09-18
Abstract: PURPOSE:To enable an ON trouble of a driving output of a fuel solenoid valve to be detected even during a long ignition operation of a combustion device by a method wherein a discharging circuit for a capacitor is opened during an ignition operation to interrupt a discharging operation. CONSTITUTION:In case that ON trouble occurs during operation and a point E is kept at 'L' to cause a flame to be shut off due to a certain cause and a flame input signal is not inputted from a point A, a charging force for a capacitor 12 is terminated and an electrical charge stored in the capacitor is discharged to a ground through a resistor 13 and a transistor 14. Due to this fact, if an inverting input terminal voltage is less than a reference voltage, a comparator output becomes 'H', a transistor 3 is turned OFF, a relay 5 is turned OFF and so the unit can be stopped safely without leakage of fuel. Just after shutting off of the flame, a prepurge state is attained, so that if a discharging time is longer than a prepurge time, an ignition operation is started and thus a danger of explosion or the like may be found, so that the discharging time is set by the capacitor 12 and the resistor 13 in such a way as it may be less than the prepurge time.
