Title: Die tightening device of molding machine
IPC: B29C33/24
Filed: 1992-03-16
Abstract: PURPOSE:To provide a die-clamping device which is simply constituted and compact in size. CONSTITUTION:A tie-rod 5 is projectingly provided to a fixed base 1 so that a movable base 3 may be movingly guided, and in this tie-rod 5, an engagement groove 5a for screws or the like is provided to the outer circumferential surface of a part projecting from the moving base 3 to the side of a counter fixed base in the condition where dies 2, 4 are closed. A locking member 12 of split die shape which is locked to/released from the tie-rod 5 through this engagement groove 5a is slidably provided in the axial direction of the tie-rod, while the moving base 3 is constituted in the upper and the lower stages 3a, 3b, and a die clamping cylinder 19 is interposed in the center part of these 3a, 3b between the vertically two-staged moving bases 3a, 3b. Thus, only one set of the die-clamping cylinder and an accessory hydraulic equipment may be sufficient, leading to a simple and compact constitution. The die-clamping cylinder presses the die directly by pressing down the center part of the downward- moving table, and even when the moving base is bent, this bending does not affect the die, preventing adverse effects to products.

Title: Resistance train for dividing reference voltage
Inventor: TAKEUCHI OSAMU
IPC: H01L27/04
Filed: 1991-02-28
Abstract: PURPOSE:To eliminate the following at a resistance train, for reference-voltage dividing use, which is used at a digital-to-analog converter of R-string system or the like: an irregularity in individual resistances forming the resistance train; an irregularity in an Al contact resistance; and the difference in an Al interconnection resistance between a return point and a straight-line part. CONSTITUTION:At a resistance trainby this invention, Al contacts 1 as electrodes are installed at equal intervals in a continuous polysilicon resistance train 2, and their cut ends at the electrodes in the resistance-width direction are alternately perpendicular and they are arranged alternately to form resistance shapes. Thereby, the influence by an irregularity in Al interconnection resistances and Al contact resistances is eliminated, and a resistance pattern is not changed even at the return point of the resistance train. As a result, a reference voltage can be divided equally.

Title: Character shape recognition method
Inventor: MURAI YASUMASA
IPC: G06K9/48
Filed: 1986-03-18
Abstract: PURPOSE:To easily grasp the outside peripheral form of a character by obtaining the inner product value between a unit vector orthogonal to a vector from the start point to the end point out of three sampling points adjacent to one another of a character pattern and a vector from the start point to the middle point. CONSTITUTION:When sampling points are taken clockwise, a point A is the start point, and a point B is the middle point, and a point C is the end point. The inner product between a unit vector  eA, which is orthogonal to a vector  AC and is directed to the outside of the character pattern, and a vector  AB, and the section AB is judged to have a projecting shape if the value of this inner product is larger than a certain value. The similar operation is performed for points B, C and D and points C, D, and E. Next, the similar operation is performed counterclockwise. Discrimination results of the counterclockwise processing and those of the clockwise processing are collated with each other to discriminate finally whether each section has a recessed shape or a projecting shape.

Title: Camera with zoom
Inventor: TABATA YASUSHI
IPC: G02B7/08
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To perform the opening/closing operations of a lens barrier again when it is determined that the lens barrier is not normally opened/closed and to prevent a malfunction by generating a specific signal in synchronization with the opening/closing of the lens barrier. SOLUTION: A rear group moving motor 30 is driven to open the barrier and when it is not confirmed that the barrier is opened, that is, an AF reference pulse input circuit 222 does not output a pulse to a CPU 210, the rear group moving motor 30 is driven in the closing direction of the barrier and then, in the opening direction of the barrier again. Then, an AF pulse counter is set. In AF pulse count processing, the set AF pulse counter has decrement, based on a pulse signal outputted from the AF reference pulse input circuit 222, in synchronization with the rotation of the rear group moving motor 30. Therefore, when the opening/closing processing of the barrier is not normally completed, the opening/closing processing can be executed again or control not for attaining processing after that is executed.

Title: Device and method for taking picture showing moment of breakdown of high speed rotor
Inventor: GOTO YOSHINOBU
IPC: G03B15/00
Filed: 1994-03-29
Abstract: PURPOSE:To take a picture showing the moment of breakdown in stable timing by detecting flash light emitted when a broken piece caused by the breakdown of a high speed rotor collides with a frame by means of a photoelectric conversion element and actuating a stroboscope. CONSTITUTION:When a turbin rotor (specimen) 12 as the high speed rotor rotated by an air turbin 10 is rotationally broken and the broken piece collides with the frame 21, the flash light is emitted. The flash light is detected by a phototransistor(photoelectric conversion element) 20 and converted into an electrical signal. The electrical signal is transmitted from the phototransistor 20 to an extreme high speed light emitting system provided with the stroboscope 30, a controller 32 and a flash 34. The stroboscope 30 emitting the light in such a way irradiates the inside of a chamber 50 through a lighting window 53 and information that the rotor 12 is rotationally broken is transmitted to a still camera 40 through a photographing window 54 by using the reflection of a sheet steel 12, then an image is picked up. Thus, the simple device excellent in repetitive photographing efficiency and capable of taking the picture showing the moment of the breakdown is obtained.

Title: Vehicular heating device
Inventor: ONIMARU SADAHISA
IPC: B60H1/03
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To perform throttle control without manually operating an operation lever by a human power. SOLUTION: When heating capabilities are insufficient in which the temperature of cooling water is not more than the specified temperature, the opening of a throttle valve 140 provided on the discharge side of a water pump 210 for circulating cooling water is decreased. Therefore, since the throttle valve 140 and the water pump 210 generate heat, insufficient heating capabilities can be compensated without manually operation an operating lever by a human being.

Abstract: PURPOSE: To prevent the output of unfixed data from a unit to a mother board at the time or inserting/extracting the unit during operation of a device. CONSTITUTION: Terminal lengths of a male connector fixed to the mother board side are preliminarily set so that the earth terminal is longest and the feed terminal, control terminals, and data terminals are shorter in order. Each of units 21 to 2n is provided with a supply voltage monitor circuit 34; and when a supply voltage Vcc doesn't keep a prescribed value, a detection signal ES in the row never is outputted to set an output control signal NS or an output control circuit 35 to the high level. Then, the output side of a data output circuit 32 is fixed to the high impedance. Since the earth terminal is first connected and the feed terminal, control terminals, and data terminals are next connected in order at the time of inserting the unit to the mother board, unfixed data is not outputted.
