Title: Synchronism fault detecting circuit of phase locked loop
Inventor: CHIBA KAZUHARU
IPC: H03L7/095
Filed: 1983-09-29
Abstract: PURPOSE:To eliminate the defect that a PLL lock fault detecting circuit responds too much to the operation of a switch by providing a voltage discriminating device detecting a prescribed level of an output voltage of a phase comparator in a phase locked circuit, an integration circuit integrating an output voltage of the voltage discriminating device and a memory circuit storing an output of the integration circuit. CONSTITUTION:The voltage discriminating device 12 and the memory circuit 14 correspond to the voltage discriminating device 10 and the memory circuit 11 of a conventional circuit. Moreover, the integration circuit 13 consists of a simple CR circuit having a time constant tau or the like. The integration circuit 13 suppresses a very fast change in the output voltage of the voltage discriminating device 12 and selects a comparatively slow change and gives the result to the memory circuit 14. The time required for the switching operation of the switch 8 is very short normally and the relocking of the PLL as the result is finished in a very short time. An output voltage change of PD based on a fault of the PLL is normally slow against the result. Thus, the discrimination of fault at the operation of the switch is made ineffective by utilizing this point.

Thus, the copy including attendant information such as the data and the address is obtained while leaving the original intact, and the labor of the hand writing work is reduced.

Title: Spot detector for trackless truck
Inventor: HIROSE NORIAKI
IPC: G05D1/02
Filed: 1984-08-31
Abstract: PURPOSE:To prevent malfunctions of a trackless truck regardless of the inferior state of a road surface and the truck driving speed and to guide the truck to its destination with high accuracy, by using a pot detector that eliminates the big variance of a marker for sensor due to the difference of the driving speed and detects accurately the position of the truck. CONSTITUTION:When the output of a spot detector 2 is changed to L from H, an output is produced from a photocoupler 5 at the side of a transistor. A preset counter 13 performs counting every time a pulse proportional to the distance covered by a truck is supplied. Then the counter 13 produces an output when its count value reaches a preset level to use it as a clock input of a J-K flip-flop 14. Here the flip-flop 14 is set and the output signal of H is applied to an AND circuit 11 in the form of a gate control signal. This control signal is applied to an output spot counter 7 of a buffer 6. The counter 7 is counted up by one at the rise of an input. In this case, the malfunction due to noises, etc. are eliminated by the output of the photocoupler 5. Thus the above- mentioned actions are repeated every time a detection plate 4 is detected. When the spot counting action is advanced up to a set level, the truck reaches its destination.

IPC: F16B39/10
Filed: 1995-06-14
Abstract: PURPOSE: To lock a bolt to a nut and to prevent looseness by fitting a stopper groove, formed in the stopping bolt, to a pawl part formed in the screw nut. CONSTITUTION: A stopper groove 2 extended in an axial direction of a bolt is formed in a side part of a bolt main unit 1, to vertically provide a screw blade 4 formed of elastic material in a screw hole surface of a nut main unit 3. When a screw nut N is screwed to a stopping bolt B, a pawl part 4a in an end part of the screw blade 4, by inserting the stopping bolt B, is rotated while coming into contact with a thread ridge in a condition elastically press spread to the outside. When the screw nut N is screwed to a prescribed position to be stopped, the pawl part 4a in the end part of the screw blade 4 is fitted to the stopper groove 2 of the stopping bolt B. In this way, the screw nut N and the stopping bolt B are locked. Even when force of shock, vibration, or the like to reversely rotate the screw nut N is applied, looseness is prevented by this lock action.

Title: Fixed metal complex
Inventor: MIKI KEIJI
IPC: C07C49/747
Filed: 1990-07-10
Abstract: PURPOSE:To obtain a metal complex fixed to an inorg. carrier useful as a catalyst for various reaction by surrounding the metal complex with long molecular chain compd. to stabilize the metal complex and properly selecting the kind of metal and ligand. CONSTITUTION:In the metal complex fixed to an inorg. carrier, a long molecular chain compd. is coupled with the carrier to surround the metal complex. The coupling ratio of the long molecular chain compd. is at least 1.5mol to 1mol of the metal complex. The fixed metal complex is prepared by allowing a short molecular chain compd. (e.g. org. silicon compd.) having such a group that collects metal ions to react and couple with an inorg. carrier (e.g. alumina). Then a long molecular chain compd. is made to react and couple thereto, so that the metal ion acquiring group (e.g. carboxyl group) acquires metal ions. Then ligands are made to react with the acquired metal ions to form the complex. In this process, by changing the properties of the long-chain compd., properties or forms of the reaction can be controlled.

Abstract: PURPOSE:To eliminate a leakage between a source layer and a drain layer and to reduce the supply of electrons from the source, drain layers to two-dimensional gas layer by forming a P-type semiconductor layer on the periphery of the source, drain layers formed in an undoped semiconductor layer. CONSTITUTION:Undoped layers 2-5 are sequentially epitaxially grown on a substrate 1.

Title: Control method of air-fuel ratio
Inventor: KAJI TAKASHI
IPC: F02D41/14
Filed: 1982-10-19
Abstract: PURPOSE:To always maintain a proper air-fuel ratio by suspending the processing for memorizing the correction information for each engine state during a prescribed delaying time for the engine operation state. CONSTITUTION:A control circuit 24 controls air-fuel ratio by controlling the fuel injection amount of an engine, and a microprocessor 100 calculates the fuel injection amount. A digital input port 103 receives a signal of an air-fuel ratio sensor 22 and transmits said value into the microprocessor 100. The correction information for each engine state is memorized into an RAM 107, and is stored during the time when the engine operation state is in transition state or during a prescribed delaying time after transition from transition state to stationary state. Therefore, the delay of response in air-fuel ratio feedback control is compensated, and a proper air-fuel ratio can be always maintained in feedback control and open loop control.

Title: Developing method for electrostatic latent image
Inventor: MATSUBARA AKITOSHI
IPC: G03G13/08
Filed: 1986-08-07
Abstract: PURPOSE:To permit good development without entailing the contamination in device by splashing of toners and carriers and without generating fogging by forming a developer layer to be formed on a developer conveying body as a thin layer and using the specific carrier. CONSTITUTION:The developer layer to be formed on the developer conveying body is formed as the thin layer, and the carrier which is the resin-coated carrier formed by coating a resin on magnetic material particles and has 1.6-2.4g/cm<3> apparent bulk density is used in the developing method for forming the developer layer of a two-component developer consisting of the toner and carrier on the developer conveying body, supplying the developer layer to a developing region where an oscillating electric field is generated and developing the electrostatic latent image on the developer conveying body. The carrier particles are thereby formed to have the spherical and smooth surface condition and the tendency to the retardance of the frictional chargeability of the carrier by sticking of the toner material onto the carrier surface is decreased. Since the carrier has 1.6-2.4g/cm<3> apparent bulk density, the flowability of the carrier is substantially high and the frictional charge between the toner and the carrier is satisfactorily executed.
