Title: Magnetic recording and reproducing device
Inventor: KANEKAWA HIROSHI
IPC: G11B15/61
Filed: 1988-06-07
Abstract: PURPOSE:To enable the high quality recording and reproducing by providing an airflow control member consisting of a prescribed shaped communicating foam material at an inlet part where a magnetic tape begins to wind around the outer circumferential surface of a rotary head assembly. CONSTITUTION:The airflow control member 22 consisting of the communicating foam material having a 1st side 22a extending along the outer circumferential surface 201 of the rotary head assembly at a distance from the outer circumferential surface 201 and a 2nd side 22b extending along the magnetic tape 1 at a distance from the magnetic tape is provided in a space formed between the outer circumferential surface 201 of the rotary head assembly and the magnetic tape 1 at the inlet part 13 where the magnetic tape 1 begins to wind around the rotary head assembly. Consequently, since air flowing through both sides of the airflow control member 22 into the inlet part 13 can be flowed backward through the airflow control member 22, the throttle of the incoming airflow is alleviated, while the floating amt. of the magnetic tape 1 due to the rise of the air pressure in the vicinity of the inlet part is also suppressed in its fluctuation. By this method, the recording and reproducing of a signal can be performed with high quality.

Title: Echo elimination device
Inventor: TAKAKUWA AKIO
IPC: H04M1/20
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent with a simple configuration the malfunctions of an echo elimination filter when the power of a received signal is increased. SOLUTION: When power of a reception signal X(n) sent through a reception path 14 is higher than a prescribed threshold, a controller 18 sends an operation control signal 19 to an echo elimination filter 20 for allowing an echo elimination filter 20 to stop estimating the impulse response of an echo path 31. When the power of the reception signal X(n) is higher, the possibility of the estimate of the impulse response of the echo path 31, including an error, becomes high. In such a case, by stopping the estimation of the impulse response, an improper simulation echo signal Y'(n) is prevented from being needlessly calculated, resultingly decrease of the Y'(n) from an echo-uneliminated transmission signal Y(n) is prevented as well.

Title: Lcd display control system
Inventor: SHIMAMOTO HAJIME
IPC: G09G3/36
Filed: 1990-05-31
Abstract: PURPOSE:To drive an LCD and a CRT display simultaneously by scanning the lines in an area other than an effective display area plural times in a period equivalent to a one-line scan in the effective display area when a display with resolution lower than vertical resolution is made on the LCD. CONSTITUTION:When the display with the resolution lower than the vertical resolution of the LCD is made on the LCD, the lines in the area other than the effective display area are scanned in the period equivalent to the one-line scan in the effective display area. A single type LCD is brought under display driving control at the display timing of the CRT display by a CRT controller. Therefore, even various display modes wherein the total vertical number of horizontal lines is less than the physically vertical number of display dots on the LCD can be supported. Consequently, the CRT display and LCD are both brought under the display driving control simultaneously.

Title: Ion detection device
Inventor: YAMADA TAKAHISA
IPC: H01J43/02
Filed: 1992-05-07
Abstract: PURPOSE:To enable an ion detector composed of a combination of a CD and electronic booster to detect negative ion with a good efficiency. CONSTITUTION:A CD 4 is arranged onto a passage of ion I to be detected, and to the CD 4 a high voltage power source 5a and a power source 5c are connected switchably through a switch S. An electronic booster 1 of which incident face has earth potential is provided in the normal line of the CD 4. In detecting positive ion I negative high voltage of about 5KV is applied from the high voltage power supply 5a to the CD 4 to make ion impinge on the CD 4 to emit secondary electron E. Then, the secondary electron is accelerated by the voltage between the CD 4 and an electron booster and applied onto the electronic booster. In detecting negative ion I relatively low negative voltage of about 500V is impressed to the CD4 form the power source 5c to make negative ion impinge on the CD 4. In the case of minus ion detection, by the application of low electric potential to the CD 4, secondary electron is discharged from the CD 4 and applied to the electronic booster 1 as the similar way in the case of positive ion detection.

Title: Position encoder
Inventor: NARUTAKI YOSHIISA
IPC: G01D5/249
Filed: 1983-08-03
Abstract: PURPOSE:To improve resolution by writing position information on a laser readout type encoding disk at right angles to its moving direction, and scanning a readout laser beam in the track lengthwise direction and obtaining the position information on the moving body. CONSTITUTION:Tracks 3 on which information bits are formed corresponding to position information codes are formed at equal intervals breadthwise at right angles to the moving direction of the encoding disk 1, and a pickup 11 including a readout optical system is movable at right angles to the lengthwise direction of the encoding disk 1. Thus, the tracks 3 are not formed in the lengthwise direction of the encoding disk 1, so the resolution is not limited by the number of bits per track (information recording density) and determined only by the pitch of the tracks 3. For the purpose, the track pitch is narrowed down and a read is taken with the laser beam to improve the resolution.

Title: Automatic measuring instrument for cake hardness
Inventor: TOGASHI TAKEYOSHI
IPC: G01N3/40
Filed: 1987-06-09
Abstract: PURPOSE:To measure automatically the real hardness of a body to be measured which has large variance in hardness obtained by averaging the surface hardness and center hardness by providing a detection part consisting of a load cell and a contactor to the vacuum sucker of an automatic cake elevating machine. CONSTITUTION:The contactor 3 of the load cell fitted to the vacuum sucker 1 of the automatic cake elevating machine 8 of a filter press is inserted into a cake 4 which is sucked by the sucker 1 and an object of hardness measurement, and the load cell 2 detects the load.

Abstract: PURPOSE:To allow a current TV picture plane to monitor reproducing contents even when a magnetic tape is quickly reproduced by storing once, at a memory every one field, video signals for N fields which are reproduced and demodulated then reading the field of video signals after selecting the stored one among them. CONSTITUTION:FM video signals reproduced by a swivel head are converted into digital video signals by amplifiers 18 and 19, a switch 20, a demodulation circuit 21 and an A/D converter 22. Horizontal and vertical synchronous signals as well as color complementary carrier signals of demodulated video signals are separated and extracted by synchronous signal separation circuits 26.

Title: Chain elongation detecting device
Inventor: KIMURA AKIO
IPC: G01M99/00
Filed: 1987-06-08
Abstract: PURPOSE:To make it possible to continuously detect elongation of a chain for engaging a pusher with a carrier vehicle or the like, by measuring the distance between a measuring surface of a rear pusher and a measuring reference surface upon detection of a forward pusher, and by marking the chain when a degree of elongation exceeding a predetermined value is detected. CONSTITUTION:When a forehead pusher 22 on a chain 23 during operation reaches a detecting device 41, a limit switch 55 is turned on so as to set a data processing device 45 in a detecting condition. Further, when the processing device 45 receives a detection signal from a light projecting and receiving section 47 in a detecting section 33 for the pusher 22, a measuring device 43 measures the distance L between a measuring surface 32 of a posterior pusher 22 and a measuring reference surface 42 and thus measured value is transmitted to the processing device 45 so as to be used as a set value. Similarly, the distance to each pusher is measured. Further, the measured values subsequent to the second cycle are compared with the set values so as to determine the degree of elongation. When a certain degree of elongation is detected, a marking device 44 marks the chain.
