Patent JP-H07303174-A (JP)
Title: Original scanner
Inventor: TSUI KOTARO
IPC: H04N1/10
Filed: 1994-04-28
Abstract: PURPOSE:To reduce deterioration in image quality within an allowable error range without large vibration of both reflecting mirrors by deviating a natural frequency of a primary bending mode of the 2nd and 3rd reflecting mirrors from each other in the original scanner. CONSTITUTION:A reflecting mirror 3 is supported at three points by a support member 13 at a prescribed position in the vicinity of both ends in the mirror lengthwise direction in the support mechanism of the mirrors of a 2nd mirror base 9, while a reflecting mirror 2 is supported at three points at the outside of the support position of the mirror 3 by a deviation of DELTA in the lengthwise direction. As a result, when an original is scanned, the frequency transfer characteristic of the reflecting mirror 3 is unchanged in the response of the reflecting mirrors 2, 3 in the scanning direction when an external disturbance is exerted by a wire 10. However, since the position of the support points of the mirror 2 is widened by DELTA in the lengthwise direction, the frequency transfer characteristic of the mirror 2 is nearly 1/10 of that of the mirror 3. That is, even when the reflection mirror 3 is vibrated in the primary bending mode, the reflecting mirror 2 is vibrated with a magnitude of 1/10 of the mirror 3 and a large vibration is avoided.

IPC: F24C7/02
Filed: 1985-05-28
Abstract: PURPOSE:To prevent the formation of dew condensation on the inner surface of a door, by arranging an air intake port at the lower side of a side wall, arranging an exhaust port at the upper side, thereby avoiding the contact of air, which is introduced from the air intake port, with the ascending stream of vapor and the like yielded from food to be cooked. CONSTITUTION:An air intake port 12 is provided at the lowermost position at the rightmost side on a plate in the direction of the width of a rear wall of a cooking chamber 2. An exhaust port 13 is provided at the uppermost position at the leftmost side, which is opposite to the air intake port 12, on the rear wall of the cooking chamber 2. The air is introduced into the cooking chamber 4 through a duct 15 and the air intake port 12 along the bottom surface of the chamber 4. The air is blown to the inner lower part of a door 1a. The air ascends along the inner surface of the door 1a and also flows along the upper surface of the cooking chamber 4 in the direction of the depth. The air reaches the exhaust port 13. Therefore, the air is not contacted with the ascending stream of vapor from food to be cooked 10. Therefore, the vapor, oil and the like are not carried to the door 4, and dew condensation is not formed on the inner surface of the door 4.

Title: Display device
Inventor: MANO HIROYUKI
IPC: G09G3/20
Filed: 1990-04-27
Abstract: PURPOSE:To speed up display data transfer by detecting the point of time when a shift enable signal is outputted to a trailing-stage driver and delaying a display data shift clock according to the detection result until the trailing- stage driver becomes ready to fetch display data. CONSTITUTION:When the display data 6 is transferred from a host device to respective drivers which are connected in plural stages to drive a display panel 2, specially, column drivers 4, the display data of a driver which inputs the display data currently is fetched and the output of the clock signal for fetching the display data by the trailing-stage driver is inhibited until the trailing-stage driver becomes ready to fetch the display data. Even if the trailing-stage driver becomes ready to fetch the display data during this period, the display data is not fetched by this inhibition, so the data is prevented from being fetched incorrectly. Consequently, the transfer of the display data is performed at a high speed irrelevantly to the state of the column drivers 4 of the display panel.

Title: Flow rate detecting device
Inventor: TAKAMITSU MASAYOSHI
IPC: G01F1/20
Filed: 1989-05-09
Abstract: PURPOSE:To detect a large flow rate with high accuracy by arranging a stop ring and a stop plate in a flow passage where a fixed blade, a ball, and a ball receiver are provided. CONSTITUTION:The fluid in a flow passage 1 is applied with a turning force by the blade part of the fixed blade 2 to flows out in a flow passage 8 while rotating the ball 4. The rotation of the rotating ball 4 is transduced into an electric signal by a rotation detector 9. The fixed blade 2 itself tries to rotate by receiving the strong turning force, but plural claw parts of the stop ring 5 catch the blade, which does not rotate. Further, the fixed blade 2, ball 4, and ball receiver 3 are forced to flow away by the flow of the fluid, but they do not move because of the stop plate 6. Consequently, the large flow range is detected with high accuracy.

Title: Memory unit
Inventor: WATANABE CHIYUUJI
IPC: G11C7/10
Filed: 1979-09-08
Abstract: PURPOSE:To shorten the output time of readout data remarkably by connecting the output terminal of a tristate memory element and a pullup or pulldown resistance to one input terminal of a gate that enables data output. CONSTITUTION:Data output RDATO of MOSRAM11 is inputted to one input terminal of gate circuit 12, but since pullup or pulldown resistance 21 is connected to it, the level of an ineffective output which should not be in a high impedance state essentially is forcibly pulled down to a low level, preventing the generation of a noise. Then, effective output RDATO, after being sent out, reaches its original level without being influenced by resistance 21. Additionally, circuit 12, before output RDATO is validated, is opened with high-level gate signal GATE, so that effective output RDATO will be sent out of circuit 12 under no influence of the skew of signal GATE. The output time of readout data is therefore shortened remarkably.

Title: Controller of ac motor
Inventor: HIRATA AKIO
IPC: H02P21/22
Filed: 1984-06-06
Abstract: PURPOSE:To improve the operating power factor and also the operating efficiency of an AC motor by controlling the control leading angle and controlling the effective commutation marginal angle to the necessary minimum value in the operation mode. CONSTITUTION:When a speed of an induction motor is abruptly accelerated, an acceleration/deceleration detector 27 is operated, and a control leading angle beta is controlled by the output signal of a superposing angle setter 28. When the variation in the speed is eliminated, the angle beta is controlled by the output signal of a superposing angle detector 25. When the angle beta is thus controlled, the effective commutation margin angle gamma' is controlled constantly at normal time. Then, stable operation of the motor can be performed by eliminating the detecting delay of the detector 25 by the operations of the detectors 27 and the setter 28 though increased in the transient period that the input current Ia varies.

Filed: 1978-09-21
Abstract: PURPOSE: To make recording paper and a recording head come in uniform and smooth contact over the whole area of a scanning path, by making use of the suction force of a magnet.  
     CONSTITUTION: Along the scanning path of recording head 2, magnetic beltlike pressure board 3 opposing each other with recording paper 1 in-between are  arranged and at an adequate place where head 2 operates by itself or together with them, magnetic 35 is placed to push pressure boards 3 provided near the magnet to the head-2 side by its magnetic force, thereby making recording paper 1 and recording head 2 in contact. The above-mentioned constitution of the recording part requires pressure boards 3 to pull only the head part, and consequently relatively- small suction force of the magnet is required while a load upon head 2 is reduced, lessining its wear. Further, meeting between recording paper 1 and head 2 is implemented by the suction of thin pressure boards 3, so that the contact pressure and contact attitude will be even and smooth at any position on the scanning line.
