Title: Frequency variation rate detecting device
Inventor: YAKURA TOSHIAKI
IPC: G01R23/09
Filed: 1981-08-04
Abstract: PURPOSE:To quantitatively grasp acceleration, a stationary state, deceleration, etc. of a vehicle, by converting the frequency of a repetitive signal to voltage, sample-holding it by synchronizing with the repetitive signal, and detecting a variation rate of a converted output which has been made to pass through an LPF. CONSTITUTION:A repetitive signal Vin of an engine rotation, a car speed, etc. is applied to a frequency-voltage transducer 1, and is converted to an output containing a DC portion and an AC portion. An output of the transducer 1 is provided to a sample holding circuit 5. To the circuit 5, a pulse of a pulse generator 4 synchronizing with the signal Vin is supplied, and as for a sample holding output, its AC portion is removed through an LPF. An output signal Vfv is inputted to a differentiating circuit 7, is coupled with reference voltage Vr which is set optionally, and a variation of the signal Vfv is detected as an output Vout. In this way, a variation of the repetitive signal can be detected quantitatively.

Title: Storage system with flash memory as storage medium and control method therefor
Inventor: HATTORI RYUICHI
IPC: G11C16/02
Filed: 1993-05-25
Abstract: PURPOSE:To extend the life of a disk by performing write to an alternate write area when a write error is generated in a semiconductor disk for which a flash memory is a storage medium. CONSTITUTION:In the case of writing data, a host system 101 instructs the write along with address information to a semiconductor memory part 106. When the write instruction is received through an interface circuit 107, the control circuit 111 of the semiconductor memory 106 reads the write address of the semiconductor memory 106 corresponding to the address information to be written from a memory block management table 112 and writes the data to the target area of a data memory 108. Then, when the control circuit 111 detects that the error is generated in a block at the time of the write, a memory management means reads the address information of an alternate memory part 109, the alternate area is allocated and the alternate area is turned to be in use. The control circuit 111 writes the data to the allocated alternate area.

Title: Vibration control device
Inventor: URANO TAKAYUKI
IPC: F16L3/202
Filed: 1978-10-06
Abstract: PURPOSE: To provide an effective restriction against a relative displacement between a supported body and a supporting body by performing a vibratory control under a combined action of an energy loss caused by a striking force generated between a driving member and an inertia body and an inertia momentum of the inertia mass.  
     CONSTITUTION: When the supported body is lsightly displaced due to some variations in temperature etc., the first member 1 is moved at a low speed and the rotary axis 17 is also rotated at a low speed. In this case, there is no resistance force for restricting the displacement of the supported body. When the supported body shows its highly accelrated displacement due to earthquake etc. and the rotary axis 17 shows a severe reciprocative rotation, the driving member 20 and the inertia mass 21 generate a vibration restricting force caused by an energy loss made by a repetitive striking at each of the side walls of the recess 27 and the projection 28, and when struck, an inertia momentum of the inertia mass 21 generates a vibration restricting force. Thus, since it is possible to have a low inertia momentum of the rotary part other than the inertia mass, to prevent a generation of resonance and at the same time to restrict an excessive resistance force, a highly accelerated displacement may be restricted.

Title: Rotary magnetic head and rotary drum
Inventor: ICHIMURA TAKESHI
IPC: G11B5/187
Filed: 1995-05-22
Abstract: PURPOSE: To obtain an ideal recording and reproducing operation by setting the ratio of the radius of curvature in the longitudinal direction of the head of a rotary magnetic head to the radius in the thickness direction of the head to a prescribed value. CONSTITUTION: An Ry/Rx is set to be <=0.17 by defining the radius of curvature in the longitudinal direction of the head to the head of the rotary magnetic head as Rx and the radius of curvature of the width direction of the head as Ry. Thus, since the omission of an RF signal accompanying the spacing of a tape from the vicinity of the center to the vicinity of the outlet of a rotary drum is eliminated, the rotary magnetic head in which the ideal recording operation of a digital signal is made possible is obtained.

Title: Endoscope device
Inventor: FUKUNISHI SOHEI
IPC: A61B1/00
Filed: 1990-05-15
Abstract: PURPOSE:To allow the transfer to a state in which a subject can be correctly observed in a short period of time without using a high capacity pump by providing a small- aperture nozzle apertured to the size to allow an air and water feed region to be reduced to the optically effective region of an observation window at the end face of the front end hard part of the scope. CONSTITUTION:The small-aperture nozzle 3 and a large-aperture nozzle 4 are provided at the end face in the front end hard part 2 of the endoscope. The small-aperture nozzle 3 is apertured to the size to allow the air and water feed region to be reduced to the optically effective region 5a of the observation window 5. The feed air or water is eventually injected to the optically effective region 5a of the observation window 5 by the small-aperture nozzle 3 constituted in such a manner. The injection pressure of the pump equipped to the device body increases greatly and a washing effect improves as compared to heretofore even if a pump having a high capacity is not used as the above-mentioned pump. In addition, the optically effective region 5a which is optically necessary is emphatically washed. The dirt, water drops, etc., particularly on the optically effective region of the observation window are, therefore, removed in a relatively short period of time and the transfer to the state to allow correct observation is possible.

Title: Hue controller

IPC: H04N9/87
Filed: 1989-05-17
Abstract: PURPOSE:To allow the use of a device which has not conversion processes of a carrier chrominance signal and a color difference signal by modulating the demodulated color difference signal to the carrier chrominance signal and switching the modulated carrier signal to a fixed phase carrier signal and a variable phase carrier signal. CONSTITUTION:The carrier chrominance signal inputted to an input terminal 1 is demodulated by a demodulator 7 with the output signal of an oscillator 6 and the signal, which is phase shifted by 90 deg. in a 90 deg. phase shifter 8, as carrier signals, and demodulated signals are supplied to a modulator 50. The modulator 50 modulates these signals with the output signal of an SW circuit 51 and the 90 deg. phase shifted signal as carrier signals and outputs the modulated signal to an output terminal 52. Thus, the signal outputted to the output terminal 52 is equal to the carrier chrominance signal inputted to the input terminal 1. With respect to the carrier chrominance signal, the hue is expressed with the chroma signal phase to the burst signal phase. Consequently, the chrominance signal which is outputted to the output terminal 52 is the carrier chrominance signal which is hue controlled by a control terminal 2.

Filed: 1992-05-15
Abstract: PURPOSE:To safely authenticate a user by using the encoding technique where the position of a pointing device is inputted by neglecting to confirm by a display device. CONSTITUTION:The moving range of a mouse 201 is divided into a left range 302, a right range 303, and a range 301 where the mouse 201 is not regarded as moved. The position of the mouse 201 at the time when the button of the mouse 201 is first clicked is taken as the origin, and thereafter, the button is clicked several time, and the mouse is moved left or right, then the button is clicked several times. This operation is repeated to from an input pattern. The mouse is moved for a certain distance or longer with the button depressed on to terminate the input. Since this pattern has wide respective ranges and the position to which the mouse is moved is set as the next origin again in the case of movement, the cumulative error of the mouse position is eliminated, and therefor, the position of the mouse is inputted without being displayed.
