IPC: G11B27/17
Filed: 1981-06-20
Abstract: PURPOSE: To accurately detect the remaining amount of a cassette tape on the basis of the discriminated diameter of a cassette hub, by performing arithmetic on the basis of rotation pulses generated by detecting rotational frequencies of a take up and a supply reel.  
     CONSTITUTION: The winding diameter of a cassette tape is constant without reference to the length of the tape, so hub diameters are made different. For this purpose, a take up reel La and a supply reel Lb are provided with rotation sensors which consists of light emitting diodes Da and Db and phototransistors Qa and Qb in combination, and the diameters D 1  of the cassette hubs are calculated on the basis of rotation pulses from the below equation. Namely, D 1   2 = D 0   2 . F 0   2  {(1/Fta) 2 +(1/Ftb) 2 -(1/F 0 ) 2 }, where Fta and Ftb are the revolutional frequencies of the take up and reels at time (t), D 0  is the external diameter of the cassette tape in the begining of running, and F 0  is the revolutional frequency in the beginning of running. Consequently, the diameters of the cassette hubs are discriminated to accurately detect the remaining amount of the cassette tape.

Filed: 1981-06-19
Abstract: PURPOSE:To detect a focus with high precision, by constituting a device so that the luminous flux having a small diameter is projected to an object along the optical axis of a photographic lens and the light in a prescribed region separated from the optical axis out of reflected lights is received. CONSTITUTION:The light from a light emitter 10 such as a light emitting diode is reflected by a mirror 12 and is projected to the surface of an object through a prescribed paraxial region along an optical axis X of a photographic lens TL. The reflected light passes through the photographic lens TL and a relay lens 2, which is arranged in the rear of a predetermined focal plane F of the lens TL, and is projected to a mask plate 8 having an aperture 8a in a prescribed region which does not include the optical axis X. Only the light passing through the aperture 8a is received by photodetectors 4 and 6, and the focus is detected by their outputs. The projection light from the light source 10 is reflected by the photographic lens TL but is intercepted by the mask plate 8, and therefore, a high-precision focus detection is performed.

Title: Vibration suppressing device of steering wheel
Inventor: INOMATA KAZUYUKI
IPC: F16F15/02
Filed: 1995-04-21
Abstract: PURPOSE: To structure a vibration suppressing device for a steering wheel compactly through effective utilization of a narrow space and allow the device to exert its vibration suppressing function fully. CONSTITUTION: A mounting plate 2 attached fast to the body of a steering wheel is coupled with a mass 4 by a plurality of elastic supporting legs 3 in such an arrangement that their peripheral surfaces are at least partially inclined, wherein at least two of the resilient supporting legs 3 have opposite inclining directions. Therefore, the mass 4 makes approx. horizontal swings without vertical swinging substantially with respect to the mounting plate 2, and two legs 3 work each other to restrict swinging of the mass 4 in their inclining directions, and the device exerts the desired vibration suppressing function without causing the mass 4 to interfere with surrounding member(s). Because the configuration is reasonable including no extra members, compared with a conventional arrangement, it is possible to embody the whole device compactly. This is also allowed to exert a proper vibration suppressing function for any vibratory trait by changing the section area of the supporting legs 3.

Title: Virtual terminal
Inventor: YONEZAWA KENJI
IPC: H04B3/46
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce the number of terminals which are set when the terminal increases to one and to eliminate the trouble to change the number of the terminals by instructing a sending-out means to send a response signal out when the address that a polling signal indicates exceeds the total number of the terminals. SOLUTION: A receiving terminal when having a transmit message at the time of the reception of a polling signal addressed to itself sends the message to a data communication line 10, but when there is not transmit message, the terminal sends EOT indicating the release of a data link to the data communication line 10. When the set number (n) of terminals 12-#i is larger than (m), a polling signal are sent out of the terminals 12-#i until addresses (m+1) to (n) regardless of no corresponding terminal. Then a receiving terminal 18 receives and outputs the polling signals to a monitor means 22. The monitor means 22 monitors the addresses of the polling signals and instructs a sending- out means 20 to send EOT out when the address is larger than (m).
