Patent JP-H03106210-A (JP)
Title: Low pass filter device
Inventor: SASAKI MITSUO
IPC: B60G17/015
Filed: 1989-09-20
Abstract: PURPOSE:To cut off a high frequency component completely by adopting the constitution such that input signals of plural input means are compared and a processing signal is not outputted at a high frequency region where a gain characteristic of each input means differs from each other. CONSTITUTION:The filter consists of plural input means a, b whose gain frequency characteristic differs and of a comparator (f) comparing input signals c, d from the input means a, b and outputting a processing signal e when they c, d are coincident. Then the input signals c, d are inputted to the comparator 5 from the input means a, b and when the frequency of the input signals c, d gets higher, the gain is reduced and they have a different gain frequency characteristic differs and the both are not coincident at a high frequency. Thus, the comparator f outputs a processing signal based on the coincidence of both the input signals at a prescribed low frequency but does not output the processing signal at the frequency region or higher. Thus, the high frequency component is cut off completely.

Title: Method for discriminating exposing of organic insulator of magnetic head
Inventor: NAKAZAWA KOJI
IPC: G11B5/455
Filed: 1986-10-17
Abstract: PURPOSE:To make non-destructive measurement by detecting the polarization characteristic arising upon passage of the fluorescence emitted by an org. material through a magnetic gap when light of a specific wavelength is projected to a magnetic head as an intensity ratio of the fluorescence in the oscillation direction components varying by 90 deg. from each other. CONSTITUTION:Light from an illuminating light source 12 enters a dichroic mirror (prism) 10 and only the light of the specific wavelength is reflected by a vapor deposited film filter of the mirror 10 and is directed toward an objective lens 9. The light of the other wavelengths is transmitted through or absorbed by the prism. The fluorescence of the specific wavelength is emitted from the magnetic had 1 when the light of the specific wavelength passed through the lens 9 is illuminated to the head 1. Said fluorescence is passed through the lens 9 and again through the mirror 10. The light of the reflected light component is shielded by the effect of the vapor deposited film filter on the prism surface and the light of the wavelength of the fluorescent component is transmitted therethrough. The transmitted fluorescent component is imaged onto a TV camera 16 by imaging lenses 13, 15. The light passage direction is made to coincide with the S direction by inserting a polarizing plate 14 in the imaging optical path. The measurement of the polarization condition when the exit light from an org. insulator 6 receives at the time of the passage through the magnetic gap 7 is permitted by rotating the same in the direction 90 deg. therewith.

IPC: H04W72/06
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a mobile communication system in which a radio base station makes a reply not in excess of a setting time of a mobile terminal equipment and a request signal of the radio base station is sent without retention. SOLUTION: A transmission processing section 12 is started in a transmission timing of a call reception slot to retrieve an ACK transmission time T3 on a holding ACK storage table. When a mobile terminal equipment 3 whose ACK transmission time is '0' is confirmed, the transmission processing section 12 uses a slot unit time till a wait time expires to insert an ACK signal to a call reception slot and deletes an identification code of the mobile terminal equipment 3 and the ACK transmission time T3 from the holding ACK storage table. Then the transmission processing section 12 repeats the operation till there is no mobile terminal equipment 3 whose ACK transmission time is '0' or one call reception slot reaches a transmission enable data length.  Suppose that there is no mobile terminal equipment 3 whose ACK transmission time is '0', whether or not there is a margin to insert an incoming call signal is confirmed and when there is any margin available, an identification code of the mobile terminal equipment is inserted.

Title: Hot water supplier
Inventor: YONEKUBO HIROAKI
IPC: G05D23/13
Filed: 1983-12-23
Abstract: PURPOSE:To enhance the safety and response of flow detector and controller as well as enable remote control startup and stoppage of hot water supply and instantaneous flow values of hot water to be set up by a method in which the supply of mixed hot water is detected by a flow detector, control is made on the startup and stoppage of a mixing valve driver and also on the flow rate of mixed hot water by a control valve by using signals from the flow detector. CONSTITUTION:Mixed hot water is flowed out by opening a control valve 42 by a flow rate setter and hot water supply indicator 48 for mixed hot water to be discharged. The flow rate of mixed hot water is detected by a detector 35 and a control valve 42 is driven through a controller 24 until a place where set flow rate is reached. Set temperature signal by a hot water supply controller 23 is compared with mixed hot water temperature signal detected by the detector 34 by the controller 24, and the mixing valve 36 is driven by the motor 31 to a place where the deviation between both signals is zeroed. The control valve 42 is closed as zero set flow rate, the stoppage, if any, of flow of hot water is detected by the detector 35 and the drive of the motor 31 is stopped through the controller 24. Even when temperature of the temperature detector 34 is lowered by cooling thereafter, the valve 36 is stayed at the previous stop position. The discharge of hot water during the resupply of hot water can thus be temporarily avoided for safety, and response can be improved because of short arrival time to the position where given temperatures can be obtained.
