Title: Alarm data collecting system
Inventor: TAKAHASHI AKIHIKO
IPC: H04B17/382
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To gather alarm data of a secondary station, even in a state wherein line quality is inferior by varying the amount of alarm data of the secondary station to be collected according to the line quality of a primary station and the secondary station. SOLUTION: The primary station 2 which is connected to an external alarm processor 1 monitors the line quality of the primary station 2 and secondary station 3 and requests the secondary station 3 to send an alarm of a rank providing data length corresponding to the line quality. The secondary station 3 performs ranking from alarm information collected by itself according to rank information specified by the primary station 2 and sends an alarm to the primary station 2 to shorten alarm data length from the secondary station 3, thereby suppressing the generation of a transmission error. Thus, even while the line quality deteriorates, an alarm of high emergency can be collected and an alarm of the secondary station 3 can securely be collected by combination with a resending procedure.

Title: Heat exchange type solar heat water heater
Inventor: AZUMA MASAYUKI
IPC: F24S90/00
Filed: 1986-12-12
Abstract: PURPOSE:To easily obtain hot water for drinking by fitting a heat exchanger within a heat-insulating tank of a solar heat water heater, and circulating clean water from the external part to a heat exchanger to be heat-exchanged with hot water within the heat-insulating tank. CONSTITUTION:A supply water valve 14a of a supply water pipe 7 is opened and water is supplied through a supply water port 6 into a heat insulating tank. Water is then allowed to flow into a heat collector 1, and solar heat energies are absorbed and water is allowed to counterflow successively into the heat insulating tank 4. When a hot water supply valve 14b of a hot water supply pipe 11 connected to a heat exchanger 5 internally fitted in the heat insulating tank 4 is opened and a tap for supplying hot water is also opened, the heat of hot water within the heat insulating tank 4 is heat-exchanged with water allowed to flow into a heat exchanger 5 from a branch pipe 8 via a flow rate adjusting valve 9, and clean hot water is supplied. The flow rate is adjusted by the flow rate adjusting valve 9 communicating with a branch pipe 8 to increase the heat exchange ratio. Accordingly, since hot water circulated within the heat exchanger 5 and heat exchanged is made clean, it can be immediately utilized as hot water for drinking, and in respective homes hot water for drinking can be obtained at low cost by utilizing solar heat.

Filed: 1990-11-02
Abstract: PURPOSE:To realize the operation of a circuit by performing delay simulation on a computer which is used to design a digital circuit so that the logic of a flip-flop is made indeterminate in the case of the input conflict of the flip-flop or when an input spike is lower than a designed value. CONSTITUTION:For the delay simulation 5 on the computer, circuit connection information 1 containing data on the digital circuit and a test pattern 2 consisting of data on an input and an output expected potential are used. A standard data base 4 is referred to by using a criterion for deciding determinate logic or indeterminate logic according to the time difference of the input conflict of the flip-flop and the time width of the input spike. In a final decision result list 6, the output expected value pattern of a test pattern 6 is compared with the output result pattern of the delay simulation 5 on the computer and when they are all coincident, it is considered that the operation of the circuit is secured. Thus, the operation of the circuit can be secured while it is easily confirmed whether the time difference of the input conflict of the flip-flop and the time width of the input spike meet standards or not.

Title: Laser scanning unit
Inventor: SAI KANEI
IPC: G02B5/09
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent noise to be generated during ultrahigh speed or normal speed rotation from increasing by providing a deflection means having a large number of mirror faces on the side face, means for focusing a deflected laser beam on a focus plane and means for reducing rotary noise arranged on the deflection means thereby reducing the pressure difference between high and low pressure regions. SOLUTION: When a polygon mirror 40 begins to turn at a specified r.p.m. through a motor M50, a high pressure region A is formed by the rotating force on the mirror face on the rotational direction side around a vertical edge 100 of the polygon mirror 40 and a low pressure region B is formed on the mirror face on the opposite side to the rotational direction. Pressure difference between the mirror face on the opposite sides is reduced through an air groove 110 made in the opposite side faces of the vertical edge 100 of polygon mirror 40 and communicating with the low pressure region B and the high pressure region A.  A fluid stripping phenomenon takes place on the mirror face where the low pressure region B belongs starting from the starting end of the air groove 110 to reduce vortex flow and a corresponding frequency band is reduced resulting in the reduction of noise by one to several dB.

IPC: G03F7/20
Filed: 1987-11-27
Abstract: PURPOSE:To detect a position satisfactorily by eliminating an influence due to an increased chromatic aberration and with little error by a method wherein an optical element which acts as a lens with reference to an alignment beam and does not have an influence on an exposure beam is provided. CONSTITUTION:After a + or - first-order diffraction beam out of diffraction beams diffracted by a diffraction grating 3 has passed through a reduction-projection lens 4, it is incident on Fresnel's zone plate 5 and forms an image of the diffraction grating 3 on a reticle 7. Because a zero-order beam is shut off by a beam bender 9, it does not reach the reticle 7. An interval of the image formed by the + or - first-order diffracted beam becomes half an interval of the diffraction grating 3 on a wafer 2. This formed image pattern, a diffraction grating pattern 8 on the reticle 7 and a moire fringe are detected by using an image detection means 12 via a mirror 10; their signal is sent to a position control means 14; an alignment operation is executed on the basis of this signal. By this setup, because a chromatic aberration and a mechanical error can be eliminated, the precise alignment operation can be executed stably.

Title: Semiconductor device and d/a converter
Inventor: KUMAMOTO TOSHIO
IPC: H01L29/78
Filed: 1990-11-02
Abstract: PURPOSE:To exhibit an excellent constant current characteristic by a construction wherein an electric resistance being a heating element is provided in the substrate of an MOS transistor and electrified from outside. CONSTITUTION:An electric resistance R being a heating element is provided in an oxide film B of poor heat conduction of a substrate whereon an MOS transistor is formed, and it is electrified through a through hole T. Due to a heat generated by a current of the transistor, the inferior heat conduction of the oxide film B of the layer below the transistor and further the heat in the electric resistance, the shift of a channel in the transistor is reduced and a region wherein the saturation characteristic of the MOS transistor is not dependent on a drain-source voltage is produced. Thereby an excellent constant current characteristic is exhibited by a low gate voltage.

Filed: 1988-11-25
Abstract: PURPOSE:To improve safety by providing the title system with a display means for informing the set state of a dummy setting means only to a card carrying person and an input cancel means for canceling a signal outputted from an identification code input means when a dummy input is set up. CONSTITUTION:The system is provided with the dummy setting means 7 for automatically setting up a dummy input function, the display means 8 for displaying the set state of a dummy input and the cancel means 9 for canceling a signal outputted from the ID code input means 5 when a dummy input is set up.
