Title: Magnetic video recording and reproducing device
Inventor: FURUHATA TAKASHI
IPC: G11B15/087
Filed: 1982-08-27
Abstract: PURPOSE:To perform frame-by-frame still picture reproduction, by detecting amplitude variation of a difference frequency component obtained by performing frequency conversion on the basis of a pilot signal, and generating a pulse signal which has specific width from the zero-cross point of the detection signal. CONSTITUTION:The difference frequency component obtained by frequency conversion based upon the pilot signal is amplified by an amplifying circuit 34, whose output G is shifted in phase by a phase shifting circuit 40 to obtain such characteristics that the zero-cross point of its output H corresponds to the peak point of the output G. The output H is shaped by a rectangular wave shaping circuit 41 into a rectangular wave I, which is supplied to a pulse shaping circuit 42, generating and outputting a pulse J with specific width every time the wave rises or falls. A control circuit 60 detects the phase of the pulse J and stops the generation of a capstan driving pulse W, stopping a tape run. Consequently, stable still picture reproduction is performed without any noise band on a reproduction screen.

Title: Method and apparatus for linear distortion compensation of acoustic signal
Inventor: RI MOTOSUKE
IPC: H03G5/00
Filed: 1994-06-29
Abstract: PURPOSE: To provide a linear distortion compensation method and the device for compensating the distortion of acoustic signals so as to be hardly discriminated by the ears of human beings while reducing the tap number of a filter in the consideration of the hearing characteristics of the human beings for the linear distortion of the acoustic signals generated from a speaker system. CONSTITUTION: The resolution of a low frequency domain in a audible frequency band is raised and the resolution is relatively lowered in a higher frequency domain. Then, a Bark scale is used, the band is divided and filter coefficients are determined. The acoustic signal of the whole audible frequency band which is not filtered by a low-pass filter is distortion-compensated by a first filter part 30. The acoustic signals of a divided band obtained by being passed through the low-pass filter are filtered so as to remove a distortion part not compensated by the signal distortion compensation of the whole audible frequency band by a second filter part 40 and then, added to the distortion compensated acoustic signals of the entire audible frequency band.  For the acoustic signals distortion compensated by the first filter part 30, a remaining signal distortion part is removed by the signals outputted from the second filter part 40.

Title: Dc lighting circuit for discharge tube
Inventor: KURIHARA KIMISATO
IPC: H05B41/16
Filed: 1989-06-09
Abstract: PURPOSE:To enable a discharge tube to be lit for variable watt numbers by permitting the output of a choke coil connected with the output side of a constant voltage circuit to be the output at the connecting ends of both heaters of the discharge tube, and thereby setting the set value of the constant voltage circuit in response to the watt number of the discharge tube. CONSTITUTION:When a power supply switch 2 is turned on, the output of a rectifying circuit 6 is smoothed out by a smoothing capacitor 7 so that a constant voltage circuit 8 permits a smoothing capacitor 22 to be charged by stabilized DC voltage. Two heaters to which fluorescent tube connecting terminals 25 and 26 are connected are concurrently heated by voltage dropped down by a heater transformer 24. A timer 4 is actuated with the switch turned on so that the contact 5 is thereby closed for the specified period of time. This permits the output of a choke coil 23 to be short-circuited so that electromagnetic energy is thereby accumulated in the choke coil 23 by short-circuited current. When the contact 5 is opened after the set time of the timer 4 has elapsed, high voltage due to transition phenomenon is applied to the heater of the fluorescent tube so that the fluorescent tube is thereby lit by DC voltage from the cirouit 8.

Title: Friction member and its manufacturing method
Inventor: KOBAYASHI YASUTADA
IPC: F16D69/02
Filed: 1981-09-21
Abstract: PURPOSE:To provide a friction member which is excellent in thermal conductivity with not so high modulus of elasticity and improved the friction property not to raise the temperature of the friction surface, by concentrically alternately piling a synthetic resin layer mixed with metallic powder and a metal layer to be united in a body. CONSTITUTION:A friction plate A is secured friction members 3 to both surfaces of a core plate 2 comprising a doughnut-like disc by adhesives 4. The friction members 3 are formed by alternately piling metal layers 5 and synthetic resin layers 6 radially and concentrically to be united in a body. Since the metal layers 5 are connected from the friction surface 7 to the core plate 2, heat generated at the friction surface 7 is rapidly diffused in the interior of the friction members 3, so that there is little temperature rise in the friction surface. The metal layers 5 are parallel to the direction of friction, so that the coefficient of friction will not become higher, the way things are going. Therefore, metallic powder 8 is mixed in the synthetic resin layers 6 by about 10vol%.

Abstract: PURPOSE:To perform addition and memory access at the same time and to improve a computing speed, by a constitution, wherein the time data at a starting point and a terminating point for an analysis section are read out of second and third memories with two addresses in real time. CONSTITUTION:The signal in an analysis section is computed by writing of data and thereafter reading of data in this computing apparatus. At this time, switching circuits 38 and 39 are switched and controlled with a timing control circuit 40 so as to connect contacts (a) and (c). For a reading address in a memory 2, the numerical value data of T/2 becomes a negative value in a polarity changing circuit 35, and the value is supplied to an adding circuit 36 together with the output of a memory 1. Therefore, the value the memory 2 has is obtained by subtracting the value of T/2 from the output of the memory 1. For a reading address in a memory 3, the numerical data of T/2 and the output of the memory 1 are added in the adding circuit. Therefore, T/2 is added to the time of the memory 1. Thus, the computation can be performed at a speed about T times the conventional speed.
