Title: Video disk player
Inventor: FUJISHIMA TOORU
IPC: G11B7/00
Filed: 1981-02-04
Abstract: PURPOSE:To raise the S/N ratio of a reproducing video information, by combining and processing the demodulating output signals obtained from plural signal detecting means. CONSTITUTION:Pickups 2a and 2b are placed on a disk 1 so that information can be detected by the timing which has been shifted from each other by an integer field period, demodulating output signals 4a and 4c are obtained through FM demodulating systems 3a and 3b and a variable delay line 9 from these pickups 2a and 2b, and are inputted to a signal processing system 5. When reproducing a moving picture, this signal processing system 5 adds the demodulating output signals 4a, 4b so as to send out a reproducing video information having scarcely a noise component, and when reproducing a static picture, the demodulating output signals 4a and 4b are switched so as to send out a reproducing video information consisting of the demodulating output signal of an odd or even field only. In this way, it is possible to obtain a reproducing video information whose S/N ratio is raised, and to reproduce a static picture having no fluctuation.

Title: Memory control system
Inventor: TSUTSUI SHIGECHIKA
IPC: G11B20/10
Filed: 1983-02-02
Abstract: PURPOSE:To standardize the control over floppy disks FD which have various recording formats by assuming the recording format of a memory when the memory is inserted into a driver and trying a read of its successively, and deciding the recording format from its success in reading. CONSTITUTION:When a recording format is detected, the 1st recording format is assumed firstly and a command for a read of one sector is generated on the basis of information on a control parameter. When the recording format of an FD inserted into the FD driver 13 is not the 1st one, the read is not performed normally and an error due to recording format dissidence occurs. A decision on the execution result of the command is executed by reading the status of the FD driver 13 and recording format numbers are changed to repeat said processing until a normal read is performed. When the driver succeeds in reading, a number I is the number of the recording format of the FD. For this purpose, this number is set in a table and the detection of the recording format is completed.

Filed: 1988-01-27
Abstract: PURPOSE:To completely prevent a passport from being formed by mounting an IC on the passport and collating a code written in this IC to a code previously registered by an external identifying machine. CONSTITUTION:An integrated circuit including a memory on which an individual code is written is disposed on the passport 1 as an IC card.

Title: Ignition timing control method
Inventor: YAMAGUCHI HIROSHI
IPC: F02P5/15
Filed: 1980-02-12
Abstract: PURPOSE: To prevent a sudden and discontinuous change of ignition timing and relieve accelerating shock when operating conditions change in an electronical ignition timing control device by controlling the variation volume of ignition timing within a specified range.  
     CONSTITUTION: The value of ignition timing M is retrieved from the primary and secondary properties responding to throttle opening from P 1 , P 2  and P 4  in a flow chart. A specified time passage is retrieved from P 5  after the throttle is fully opened. The ignition timing value PD from the previous operation and the ignition timing M are compared by P 7 , P 9 , P 10  and P 12 . Responding to the comparison result, the ignition timing values PD and M are controlled by P 8 , P 11  and P 13  below a specified value. P 7  and P 12  are applied for the angle of advance while P 10  is applied for the angle of delay. With this construction, the difference between the ignition timing values PD and M can be controlled below a specified value in all cases, which prevents ignition timing from suddenly and discontinuously changing.

Filed: 1979-02-14
Abstract: PURPOSE:To prevent deviation of a retainer by making the movement of the retainer half as large as the movement of a table and making the movement of the intermediate point of a bellows coincide with the movement of the table. CONSTITUTION:Tables 5 and 6 are fitted with four straight guide rails 3. A one- dimension-movement table, fitted with retainer 1 and rotors 2, is mounted on base 7 sealed by specimen chamber 8. Movement control rod 9 is sealed airtight by bellows 11 at the place where it passes through the specimen chamber 8, and it is connected to table 5 by means of metal connector 10.

Title: Room cooler of ice heat accumulating type
Inventor: NAKAKOSHI TAKESHI
IPC: F25C5/18
Filed: 1987-01-26
Abstract: PURPOSE:To control for sure the quantity of produced ice in an ice heat accumulator by providing the ice heat accumulator with a section with a small cross section for absorbing the volume expansion, amplifying the change in the water level due to volume expansion, and detecting the amount of produced ice with high accuracy. CONSTITUTION:A water level amplifier 11 has a cross section much smaller when compared with an ice heat accumulator, and the increase and decrease in the quantity of water are thereby represented by a large change in the water level. Because the ice heat accumulator is of water filling type, the volume expansion due to the phase transformation from water to ice in the ice heat accumulator is entirely absorbed by the water level amplifier 11: a change in the water level is twice as large as the case without the water level amplifying tube 11 if the cross section of the water level amplifying tube 11 is 1/2 of the cross section of the ice heat accumulator, and the change in the water level is 3 times if the former cross section is 1/3 of the latter cross section. Accordingly with a water level detector of the same measurement accuracy used, the amount of produced ice can be controlled with high accuracy. When the cold water in the ice heat accumulator is forced to flow, waves seldom developed on the water surface in the water level amplifying pipe 11 so that a change in the water level can be detected as usual and the amount of the produced ice can be controlled with high accuracy.

Using the corrected relation, the estimated shape of strip on the outlet side of rolling mill at each pass is determined based on rolling conditions at each pass of the present rolled stock and the initial set values of the respective vender force of the intermediate and work rolls of rolling mill 1 at each pass are corrected so that deviation between each estimated shape and the target shape is eliminated.
