Title: Rotary head type recording and/or reproducing device
Inventor: ASANO TAKASHI
IPC: G11B33/10
Filed: 1992-10-27
Abstract: PURPOSE:To prevent the seizure on a display device and to prolong the service time of the device by switching the brightness of a display part to two steps by discriminating whether a rotary head is rotating or not. CONSTITUTION:A control signal is sent to a control part 8 from a signal processing circuit and a motor 5 is driven and controlled by it. At the same time, information concerning to the operation of recording and reproduction is displayed on the display part 11 by the control part 8. At this time, the brightness of the display part 11 is set to the normal brightness via a brightness control part 10 in the control part 8. Then, when the rotation of the rotary head is judged to be finished or stopped in a rotation deciding part 9, the control signal is sent to the control part 10 via the control part 8 and the brightness of the display part 11 is lowered. Thus, whether the rotary head is in the operation of the recording and reproduction or in a stopped state is easily discriminated.

Filed: 1994-10-28
Abstract: PURPOSE: To provide a high-efficiency phase and amplitude modulated signal by processing a low power amplitude modulated input while separating it into 1st and 2nd constant envelope signals. CONSTITUTION: The phase modulation and amplitude modulation of low power input signal are separated by a limiter 101 and an envelope detector 102. The output of limiter 101 becomes the 1st constant envelope signal and becomes the 2nd constant envelope signal phase-shifted at 90 deg. by a phase shifter 128. The outputs of limiter 101 are inputted through a voltage controlled gain cell 103 to total sum circuits 106 and 107. At the total sum circuit 106, the weighted sum signal of 1st and 2nd constant envelope signals is generated. At the total sum circuit 107, the weighted difference signal of 1st and 2nd inverted constant envelope signals is generated. The outputs of total sum circuits 106 and 107 are inputted through limiters 112 and 113 and power amplifiers 114 and 115 to a power combination circuit 116.  At the combination circuit 116, inputted constant envelope outputs V1 and V2 are combined and a single amplitude and phase modulated output signal are supplied to a load such as an antenna.

Title: Toner transfer pump
Inventor: HASEGAWA MITSURU
IPC: F04C2/107
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation and rupture of toner grains by making the maximum surface roughness of at least part of the outer periphery of a rotor and the inner periphery of a stator smaller than the average grain size of the toner grains. SOLUTION: In this toner transfer pump 5, the maximum surface roughness of a part of the outer periphery of the rotor 24 and the inner periphery of the stator 25 is set smaller than the average grain size of the transferred toner grains. In other words, in at least a part of the surface where the rotating rotor 24 and the fixedly arranged stator 25 come into contact with each other, to be engaged, the maximum surface roughness is set smaller than the average grain size of the toner grains. Since surface roughness is set in this way, the transferred toner is held on the outer periphery of the rotor 24 or the inner periphery of the stator 25 or smoothly carried without staying for a long time. Thus, high pressure is not continuously exerted on the toner grains for a long time, to prevent the deformation and rupture of the toner grains.

Title: Ophthalmologic photographing device
Inventor: MATSUMOTO KAZUHIRO
IPC: A61B3/14
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To enable efficient photographing by indicating a fixed sight target to an arbitrary fixed position. SOLUTION: The indicating position of a fixed sight target is controlled by an operation switch 7 through a CPU 19 to an arbitrary position, and the fixed sight targets for the right and left eyes are independently controlled in accordance with the detecting condition of a detection switch 21 for storing them into a memory 20 right and left separately. Then, the insertion and extraction of a front-eye-observing lens 9 is controlled by a front-eye/eyeground observation changeover switch 6, and in the front-eye-part observing condition where the front-eye-observing lens 9 is inserted into the optical path, the input of the operation switch 7 is invalidated, and the indicating position of the fixed sight target is not changed. Further, in the front-eye observing condition, the input of the operation switch 7 is invalidated, and even if the operation switch 7 is operated, the indicating position of the fixed sight target is not changed. Since the fixed sight target is always indicated so as to be fixed to the same position in this way, the photographing in the same photographing range can be enabled.
