Title: Preventing method for malfunction of electronic timer
Inventor: YAMADA KEIICHI
IPC: H04N5/782
Filed: 1981-03-02
Abstract: PURPOSE:To prevent malfunction by incrasing resistance to an external voltage noise by holding a CR input terminal at a low potential while oscillation is stopped by holding an input to an oscillation stop control input terminal at a level (H). CONSTITUTION:If an AC side is powered down owing to a power failure, etc., during the operation of a timer IC2, the voltage of a battery 11 drops down to about 50V. As a result, the output of a differential amplifier 12 goes down to make an electric connection between an output side and a minus terminal, and the output of an amplifier 14 goes up to hold the oscillation stop control terminal 2 of the timer IC2 at a level (H), stopping the operation of an oscillator. Namely, a noise resistance level is extremely low in this state. On the other hand, the output side of the differential amplifier 12 is connected to the CR terminal 3 of the timer IC2 through a resistance 22 and a diode D13, and consequently a voltage at the terminal 3 is raised nearly up to the output-side voltage of the amplifier 12, so that the level of resistance to an external noise is improved by about 20dB as compared with that when the voltage at the terminal 3 is held high.

IPC: B01J3/00
Filed: 1984-02-22
Abstract: PURPOSE:To prevent the damage of a conveyor means or gates between vacuum chambers, by holding the open state of gates between vacuum chambers for a definite time even if a power source is turned OFF by power failure and retracting the conveyor means from the gates between vacuum chambers during the holding time. CONSTITUTION:In an apparatus wherein vacuum chambers 1-3 are provided so as to be capable of being communicated to each other through gates between vaccum chambers opened and closed by the ON/OFF operation of a power source 18 and conveyor means 6, 7 are provided so as to convey an object to be treated between vacuum chambers through the gates therebetween, an auxiliary power source 19 for holding the gates 4, 5 between the vacuum chambers to a state, before the power source 8 is turned OFF, for a definite time when the power source 18 is turned OFF is provided. That is, because the open state of the gates between vacuum chambers can be held for a definite time even if the power source 8 is turned OFF by power failure, the conveyor means can be retracted from the gates between vacuum chambers during this time and the damage of said conveyor means and said gates can be prevented.

Title: Image forming device
Inventor: OJIDA HIDETSUGU
IPC: G03G15/04
Filed: 1985-02-19
Abstract: PURPOSE:To form the image of the entire surface of an original securely by delaying the start of image formation according to the detection result of the distance of displacement of the original from the reference part of an original platen. CONSTITUTION:If the original is displaced from the reference position in a (d)-coordinate direction, the hatched part of the original is detected by a pressure sensor 90 by utilizing the pressing force of an original cover 11 and a low-level signal is stored in the address of a memory 120 which corresponds to the detected part. A main processor group 71 calculates coordinates of end parts of the original from the contents of the address of the memory 120 and compares them with reference coordinates 0 to judge that the original is displaced from the reference position only in the (d)-coordinate direction, thereby calculating the quantity (x) of displacement in the (d)-coordinate direction. Then when a copy key is pressed, the processor group 71 delays the start timing of copying operation by the quantity (x) of displacement and starts the copying operation. Consequently, the copy of the entire surface of the original is taken securely.

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To improve the versatility of the attaching position of a wiring fastener by providing many fastening teeth to the main body of the fastener, having a U-shaped cross section in a comb-teeth state or in tapered states with teeth having expanded front ends. SOLUTION: A main body 11 of a wiring fastener has a U-shaped cross section and many comb teeth-like fastening teeth 12 provided on the upper surface of the main body 11. Each fastening tooth 12 has a narrow joint section and an expanded tapered front end section, and when a wire 14 is tied with a bundling band 13, the wire 14 spontaneously slips down to the narrowest position of the fastening tooth 12. Consequently, the wire 14 will not be shifted in the forward-backward direction nor deflected laterally, and even when a force is applied to the wire 14, the band 13 is tied more strongly toward the front end of the tooth 12. Therefore, the wire 14 does not slide.  When fastening holes 17 are formed at appropriate intervals on the side face 16 of the main body 11 separately from tapped holes, wires extended in the length direction of the main body 11 through the band 13 can be fixed to the holes 17. In addition, the fastening holes 17 can also be used as tapped holes.

Abstract: PURPOSE:To perform cutting work of asphalt pavement without causing any pollution by a method in which laser beam is irradiated from a great output carbon dioxide laser device to the peripheral sides of a given range of asphalt pavement for melting and cutting, and the cut asphalt portion is removed. CONSTITUTION:In repairing a road consisting of a surface layer 5, a base layer 6, an upper roadbed 7, a lower roadbed 8, and a subsoil layer 9, a dividing line is set up for a removable area range in the portion to be cut off. Laser beam 2 from a laser generator 1 is irradiated through a light-focusing mirror 3 to the dividing line to melt and cut it off.

Title: Digital servo device
Inventor: HAMURO TAKEHIDE
IPC: G05D3/12
Filed: 1993-01-27
Abstract: PURPOSE:To reduce the phase delay cuased by the dead time which is produced by expansion of the control band width. CONSTITUTION:A comparing part 11 calculates the difference between a target value signal 6 and a main feedback signal SB, i.e., the output of a detecting part 19 which detects the controlled variable of a controlled system 17. This control deviation signal is converted into the digital value by an A/D converting part 12 and then converted again into the analog value by a D/A converting part 15 after undergoing a compensational operation in a microprocessor 16. An operating part 18 operates the system 17 based according to the analog value. Then, the data is obtained for interpolation of the time compensational operation data smaller than the compensational operation time and then put between the compensational operation data for execution of the D/A convertion. Thus, it is possible to increase the output rate of the D/A conversion and to reduce the dead time caused by the zero-order holding characteristic.

Title: Solid-state image sensor
Inventor: MURAKAMI NORIO
IPC: H04N5/359
Filed: 1988-02-16
Abstract: PURPOSE:To cause the manufacturing process a sensor to be performed at a low temperature and shorten its manufacturing time, by making an epitaxial layer containing P-type impurities grow after providing an N-type impurity region at a photodiode part and making use of auto-doping of impurities by an N-type impurity layer. CONSTITUTION:As a natural consequence of repeating various thermal treatment processes on an N-type impurity layer 2 on an N-type semiconductor substrate 1, upward diffusion A to a P-type impurity epitaxial layer 3 takes place to form epitaxial layers in such a way that a shallow P-type epitaxial layer is formed below a photodiode part and the P-type epitaxial layer that is deeper than the above shallow one is formed at regions other than the part below the photodiode part. In this way, P-type well layers having two kinds of depths are formed by utilizing an auto-doping phenomenon of the N-type impurity layer 2 which is formed on an interface between the P-type epitaxial layer 3 and the N-type semiconductor substrate. Thus, the manufacturing process of the sensor is performed at a low temperature and its manufacturing step is shortened.
