Title: Recording and reproducing method of optical disc
Inventor: NAGASHIMA MICHIYOSHI
IPC: G11B7/00
Filed: 1983-11-29
Abstract: PURPOSE:To track two spots by making the interval between centers of two laser spots in the radial direction of a disc slightly shorter or longer than a half of the interval between mountains of V grooves. CONSTITUTION:The interval between centers of two laser spots in the radial direction of the disc is made shorter than a half of the interval between mountains of V groooves by 2delta. When the interval between mountains of V grooves is denoted as P, a 2sin(2pidelta/P)-fold signal of a tracking signal due to one laser spot is obtained. In this case, a recording part (recording bits) 22 is obtained on a recording material thin film 21. The upper limit of the length delta is deltamax=(P/2- nu)/2 where nu is the width of recording bits 22 for the purpose of preventing overlap of recording bits 22-1 and 22-2. For example, if the track pitch P is 1.6mum and the recording bit width nu is 0.6mum, the upper limit deltamax is 0.1mum, and the tracking signal from two spots is >=77% of that due to only one spot and is enough.

Title: Semiconductor logic circuit
Inventor: NANBU HIROAKI
IPC: G11C11/417
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a semiconductor logic circuit and to prevent malfunctions by adding a means for forced resetting into a precharge state at the time of a discriminative state to a 2nd logic gate RC. SOLUTION: The 2nd logic gate RC is provided with a delay circuit IVA and a NOR gate NOA. Then, the gate width of a PMOS inside the IV 1 is widened and the gate width of an NMOS is narrowed. Other wise, the gate width of a PMOS in an TV 2 is reduced and the gate width of a NMOS is widened. Thus, since the on-resistance of a logic block to be turned on at the time of the discriminative state is reduced, the switching of output RO to the discriminative state is accelerated. At the same time, the switching of RO to the precharge state is accelerated as well. Therefore, the period of the discriminative state is not increased but fixed. Thus, even when a circuit reducing the power consumption at the output RO in the precharge state and increasing the power consumption in the discriminative state such as the word line of a memory is driven, for example, power consumption is not increased.

Abstract: PURPOSE: To facilitate an invert building work by a method wherein the inflow port and the outflow port of a manhole are temporarily interconnected through a flexible pipe, and by using the flexible pipe serving as molds, a curing material is poured to build a flow passage. CONSTITUTION: A flexible pipe 4 is inserted in a bent state between an inflow port 2 and an outflow port 3 bored in the side wall of a manhole body 1 and two ends are temporarily interconnected. A curing type material 6 enough to bury approximately a half of the flexible pipe 4 is poured to the bottom of the manhole body 1. After lapse of the curing time of the curing type material 6, the flexible pipe 4 is lifted for removable to build an invert 7. A groove- form flow passage 71 of the invert 7 is formed in a shape conforming to the outer peripheral shape of the lower half part thereof by using the flexible pipe 4 serving as forms.

Title: Illumination control circuit
Inventor: KOJIMA MITSUNARI
IPC: B60Q3/04
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To continuously control the quantities of light from a combination meter and an interior illumination lamp day and night through the operation of a single member. SOLUTION: At daytime running where an ignition switch SW1 is turned on, a driving voltage or battery voltage is inputted through the switch SW1 and a diode D1 into a chopper control circuit 121, which in turn outputs a switching signal S to switch over a current-control transistor Tr21. A current correspondingly flows through the switch 21, a meter lamp LM, a transistor Tr12 and the transistor Tr21 to the ground to bring the lamp LM on and thus a combination meter 110 backlit, which makes meter-indication characters visually recognized. At nighttime running, a driving voltage is inputted through the switches SW1 and SW2 and the diodes D1 and D2 into the chopper control circuit 121, which in turn outputs a switching signal S to switch over the current-control transistors Tr21 and Tr22.

Abstract: PURPOSE:To utilize sensible heat of high temperature gas passing through inside an inner tube by disposing an endothermic section on the high temperature gas introducing side of the inner tube and an exothermic section of the raw material gas introducing side of a catalyst layer and providing a heat pipe in which operating liquid is enclosed. CONSTITUTION:A catalyst layer 7 having a double tube structure consisting of an outer tube 2 and an inner tube 6 and filled with catalysts 3 in an annular space disposed between the outer tube 2 and the inner tube 6 is disposed, and raw material gas introduced into the outer tube 2 and passing through the catalyst layer 7 is discharged out through the inside of the inner tube 6.

In other words, sensible heat of high temperature gas passing through in the inner tube is absorbed by the endothermic section of the heat pipe and heat transferred to the exothermic section of the heat pipe, through which heat is dissipated on the raw material gas introducing side of the catalyst layer to utilize the sensible heat of high temperature gas passing through the inner tube effectively.

Title: Method for judging coking termination time in coke oven
Inventor: YAMAMURA HARUO
IPC: C10B57/00
Filed: 1983-11-28
Abstract: PURPOSE:To enable coking termination time to be consistently judged irrespective of fluctuation in operating conditions, by detecting the ending time of gas evolution at the end of dry distillation by measuring the temp. of gas evolving in a riser. CONSTITUTION:Coking termination time is judged from the formula, tc=to+a (wherein tc is a judged coking termination time; to is time at which the temp. curve of evolving gas exhibits an inflection point; a is a constant determined by the oven) by measuring the temp. of a gas evolving in the riser of a coke oven and detecting the time at which the change of the temp. of the gas evolving at the end of dry distillation exhibits an inflection point at which the temp. curve changes from upwards convex to downwards convex. According to this method, the coking termination time can be surely judged from only the temp. of the gas evolving in the riser irrespective of fluctuation in the operation factors of the coke oven so that the coking termination time can be judged with high accuracy even when different types of ovens are used. Hence, the lowering of the quality of coke and the loss of fuel energy as a heat source for dry distillation can be prevented.

Filed: 1990-08-28
Abstract: PURPOSE:To prevent the delay of the output processing to an external output device by giving the inhibition and permission instructions to the operating software for the interruption received from an application task. CONSTITUTION:The transmission data (a) sent from a data terminal equipment 4 is received by a received interruption processor 5 of an operating software 2. A reception data processor 7 of an application task 3 reads the reception data (b) out of a reception buffer 6 and sends the processing data (c) to an output processor 8. The processor 8 sends the output data (e) to an external output processor 9 of the software 2 and at the same time outputs a received interruption inhibiting construction (d) to the processor 5. The processor 9 outputs an output end signal (g) after the end of output of the output data (f) to an external output device 10. The processor 8 receives the signal (g) and outputs a received interruption permission instruction (h) to the processor 5. Thus it is possible to prevent the delay of the output processing to the device 10 that is caused by the interruption processing or its overhead.
