Title: Output-signal processing device of karman vortex sensor
Inventor: MITSUYASU MASAKI
IPC: G01F15/075
Filed: 1983-09-02
Abstract: PURPOSE:To prevent the erroneous detection of a flow rate due to missing of pulses, by guiding the output of a Karman vortex sensor to a period detecting means through a waveform shaping means, comparing one period with the maximum value, making the period lower than the maximum value, and computing the flow rate by a flow-rate operating means. CONSTITUTION:When vortexes are yielded in a pipe 1 by a vortex yielding body 2, the vortex pressure rotates and vibrates a vibrating plate 5 through an intake port 3 and a pressure transmitting path 4. A photodiode 9 detects light, which is emitted by a light emitting diode 8 and reflected by the vibrating plate 5. The output of the photodiode 9 becomes a sine wave state. The output signal in a sine wave shape from a Karman vortex sensor 31 is converted into a rectangular signal by a waveform shaping circuit 32 and inputted to an interrupting input of a CPU33. A clock signal is sent to a counter 35 from a clock signal generating circuit 34 based on the rise up of the rectangular signal. The period of the rectangular signal is sent to the CPU33 and compared with the maximum value stored in an ROM37. The value is set in the value lower than the maximum value, and the flow rate is computed. Therefore, erroneous detection of the flow rate due the missing of pulses can be prevented.

IPC: F24C3/12
Filed: 1981-10-09
Abstract: PURPOSE:To reduce the quantity of overshoot of temperature control by changing over  combustion to weak combustion when strong combustion time is kept within set time  and to strong combustion when weak combustion time exceeds set time. CONSTITUTION:When a control circuit 16 is conducted, solenoid valves 20, 21 are opened by means of a sequence circuit 26, an igniter 24 and a flame detecting circuit 25  are operated, and a gas burner maximally burns. When temperature in a cooking chamber reaches set temperature, a temperature detector 11 is changed over to a normally- opened contact 18', and combustion is stopped. When temperature in the cooking chamber reaches set temperature or lower, the detector 11 is changed over to a normally- closed contact 18, and combustion is conducted. When the duration of combustion is  within the set time of the first timer 27 under the state, the transistor 43 of an equivalent circuit 44 is turned ON when changing over to the normally-opened contact 18',  a transistor 23 for driving the solenoid valve 21 is turned OFF when changing over to  the normally-closed contact 18 when temperature drops, and 50% combustion is obtained. When combustion time exceeds the set time of the second timer when 50% combustion, the transistor 43 is turned OFF, the transistor 23 is turned ON, the solenoid valve 21 is opened, and combustion is changed over to 100% combustion.

Filed: 1992-06-19
Abstract: PURPOSE:To enhance isolation and facilitate assembling and adjusting work and control by disposing two Faraday rotors between two doubly refracting plates, and disposing a polarizer between the Faraday rotors. CONSTITUTION:A ray (a) of light emitted from a semiconductor laser beam source enters a first doubly refracting plate 29 and is separated into normal and abnormal rays of light having planes of vibration perpendicular to each other. The normal ray of light incident on a first Faraday rotor 31 has its plane of polarization rotated clockwise by 45 degrees and the abnormal ray of light has its plane of polarization rotated counterclockwise by 45 degrees so that the planes of polarization of the two rays of light coincide with each other. Because a polarizer 33 is so disposed that the direction in which polarized light is transmitted through it coincides with the planes of polarization of the two rays of light, the two rays of light are transmitted through the polarizer 33 and the plane of polarization of the normal ray of light incident on a second Faraday rotor 32 is rotated clockwise by 45 degrees to form an abnormal ray of light, and the plane of polarization of the abnormal ray of light is rotated counterclockwise by 45 degrees to form a normal ray of light, and the normal and abnormal rays of light are coupled together by a doubly refracting plate 30. Reflected light (b) incident from the reverse direction is separated into two rays of light, which are blocked by the polarizer 33.

Filed: 1995-06-27
Abstract: PURPOSE: To provide a manufacturing method for reducing manpower and improving productivity and also preventing the coming-off of gelcoat resin so as not to impair the outer appearance of a resin molded product. CONSTITUTION: A gelcoat resin layer 2 is formed on a molding surface of a molding tool 1.

Title: Picture display control method for picture processor
Inventor: MIMURA NORIKO
IPC: G06T1/00
Filed: 1990-06-20
Abstract: PURPOSE:To display a picture in an optimum state by providing plural thinning means in the thinning processing of picture data and selecting the optimum thinning means in correspondence with plural thinning means if necessary. CONSTITUTION:The high speed thinning circuit 8 and the high picture quality thinning circuit 9 are provided for a picture processor 11. An operation circuit 4 calculates a reduction rate for displaying whole picture data by adjusting it to the resolution of a display device 7. A judgement circuit 5 judges which thinning method of the high speed thinning circuit 8 or the high picture quality thinning circuit 9 is effective. If it is assumed that simple high speed thinning is optimum when the reduction factor is less than 1/3-fold and high picture quality OR thinning when the reduction rate is more than 1/4 fold, the reduction rate becomes high when the operation circuit 4 calculates the reduction rate of 1/5-fold. Thus, the judgement circuit 5 judges the high quality thinning circuit 9 as the effective method.

IPC: H03B28/00
Filed: 1987-06-29
Abstract: PURPOSE:To improve the waveform accuracy by providing a 1st means generating a triangle wave in response to the input changed monotonously, a 2nd means receiving the triangle wave and generating a couple of triangle wave outputs and a waveform shaping means converting the output into a waveform component with a different tilt. CONSTITUTION:A triangle wave generating circuit 2A generates a triangle wave voltage Va in response to an input voltage Vin increasing or decreasing monotonously. A triangle wave generating circuit 2B receives the triangle wave Va to generate a couple of corresponding triangle wave voltages Vb. A waveform shaping circuit 4 converts the waveform component increasing/ decreasing the triangle wave voltage Vb into the waveform component with different tilt to generate a waveform output voltage Vout representing a pseudo trigonometric function. Thus, the waveform component is independent of the resistance ratio using a resistor circuit connected in series and the waveform component is independently of the temperature coefficient of the resistors.

Filed: 1978-12-23
Abstract: PURPOSE: To make it possible to form a pn junction at the desired place by providing a diffusion restricting layer in the process of manufacturing a semiconductor device having a hetero junction and a pn junction.  
     CONSTITUTION: p-Type B semiconductor is grown on n-type A semiconductor n-A, and n-A/p-B junction is formed. In this case, a layer containing an impurity (p in this case) having a higher diffusion speed and a layer which does not contain the same impurity, that is, non-doped layer non-B are placed between two layers, n-A, and p-B. When p-B growth is operated under this condition, p-type impurity is diffused in n-A layer, and n-type impurity is diffused in p-B layer. Here, since the diffusion speed of the p-type impurity is higher, pn junction 1 is formed at the place deviated toward the n-A side from hetero boundary surface 2. Consequently, by controlling the thickness of layer non-B, it is possible to form pn junction 1 of any desired depth regardless of impurity concentration, growth temperature, and growth time.
