Title: Analog-to-digital converter circuit
Inventor: NIINOU MAKOTO
IPC: H03M1/14
Filed: 1981-12-16
Abstract: PURPOSE:To eliminate errors at a joint between lower-order and upper-order bits, by forming a reference voltage of a converter for the lower-order bit based on the output of a converter for the upper-order bit and providing an offset corresponding to the upper-order bit for this reference voltage. CONSTITUTION:A 3-bit parallel A/D converter 1 converts an analog input signal Vin into 3-bit digital signals H2-H6. In this case, a 68V upper limit reference voltage is applied to the converter 1 from a reference power supply 2 and a 4V lower limit reference voltage from a reference power supply 3. The signals H2- H0 are applied to a D/A converter 4, where the signals are converted into an analog voltage V4 having a value equal to 8 times the signals except for H2- H0=(111) and the analog voltage is applied to a converter 5 as a lower limit reference voltage. The V4 is offset at a DC power supply by 2 LSB of the signals H2-H6, i.e. 16V to from an analog signal V6, which is applied to the converter 5 as a upper limit reference signal.

IPC: G01L9/00
Filed: 1989-08-04
Abstract: PURPOSE:To prolong the life of a pressure sensor and to improve the pressure sensitive capacity by providing a partition wall with a passage communicating to both sensor changers of a detector body and internally sealing a pressure medium liquid in this passage and the two sensor chambers. CONSTITUTION:Two fluids (a), (b) to be measured varying in the respective pressures P1, P2 from each other are introduced respectively from directions A, B into pressure conducting paths 29, 30, by which the fluid pressures are detected as the sum of the respective output of semiconductor pressure sensors 27, 28. The fluid (a) introduced into the pressure conducting path 29 applies the pressure to the rear surface of the sensor 27 at this time. On the other hand, the fluid (b) introduced into the pressure conducting path 30 applies the pressure to the rear surface of the sensor 28. The diaphragm parts 27a, 28a of the sensors 27, 28 are projected to an upper side and a lower side by the differential pressure  P when the pressures P1, P2 of the fluids (a), (b) are P1>P2. The diaphragm surfaces of the sensors 27, 28 are, therefore, protected from the outside by selecting the pressure medium liquid 32.

Title: Magnetic recording medium and it production
Inventor: SUZUKI MASAYASU
IPC: B42D15/10
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction and to obtain stable reproduced signals by magnetizing a magnetic layer so as to be balanced with noise at the time of reading while applying a DC bias magnetic field, thereby diminishing the output of the noise from the card edge. SOLUTION: This medium 1 has a magnetic layer 3 having 1500 to 5000Oe coercive force on a nonmagnetic substrate 2. the layer 3 is magnetized by a CD magnetic field after completely demagnetized by an AC magnetic field. The intensity of magnetization is controlled to be balanced with the pulse noise produced on the edge at the time of reading while a DC bias magnetic field is applied. The intensity may be changeda little according to the reading rate, the DC bias magnetic field to be applied, and kinds of a reading device, and is preferably 1-30% of the saturation magnetization of the layer 3. For example, when information is read out at 1000m/sec while 100G bias magnetic field is applied, the layer is magnetized by a DC magnetic field of about 1.5kG. The noise from the card edge is thereby diminished.

Title: Acceleration detecting device provided with piezoelectric type acceleration sensor
Inventor: SHINTANI TETSUYA
IPC: G01P15/18
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To provide an acceleration detecting device with a piezoelectric type acceleration sensor capable of accurately detecting an acceleration which oscillates at a frequency of not more than 1 Hz. SOLUTION: A piezoelectric ceramics substrate 4a has one or more detecting electrodes 4b on its front face, and one or more opposite electrodes 4c opposite to the detecting electrodes 4b on its rear face. When the piezoelectric ceramics substrate 4a is bent by application of an acceleration, spontaneous polarization charges are generated in the detecting electrode 4b so that a piezoelectric type acceleration sensor 4 outputs an output signal. The output signal from the piezoelectric type acceleration sensor 4 is amplified by an amplifier circuit 2 with an offset voltage as the center. A very high resistor R7 is interposed between an output point of an offset reference voltage generating circuit 3 generating an offset reference voltage which serves as a reference of the offset voltage and a signal input terminal of the amplifier circuit 2.  A resistance value of the very high resist or R7 is set to a larger value than an impedance value which the piezoelectric type acceleration sensor 4 shows at the time of detecting an acceleration which oscillates at a frequency of not more than 1 Hz.

Title: Compound semiconductor laser device with waveguide path
Inventor: KATOU NAONORI
IPC: H01S5/00
Filed: 1988-08-16
Abstract: PURPOSE:To prevent a mirror from absorbing light, thus resulting in self-destruction by providing a waveguide path so that laser oscillation light may not be absorbed by one area from both edges of a resonator to the inside and providing a non- absorption reflection mirror at both edge surfaces of the laser resonator. CONSTITUTION:Stripe grooves 5 and 6 with a depth of approximately 0.8mum are formed in parallel to the direction <1-10> and then undoped Al0.42Ga0.58As layers 7 and 8 are formed on the stripe grooves 5 and 6 by approximately 0.8mum. A stripe groove 9 with a depth of 0.8mum is formed for the direction <110>. Then, a stripe groove which is narrower than the gap between the stripes 7 and 8 is formed in parallel to the direction <1-10>. And then, an n-Al0.35Ga0.65As layer 10 is selectively formed by a growth method. Then, a P-Al0.35Ga0.65As layer 11 is also embedded and cleavage is made at the inside of a layer embedded in parallel to the direction <1-10>, thus forming a waveguide edge surface. Since the undoped layers 7 and 8 have smaller reflection factor than that of an active layer 3, they function as a waveguide path and do not absorb laser oscillation light and function as a layer for preventing deterioration of edge surface since the band gap is large.

Title: Switching device for lighting
Inventor: KAWASE YASUTAKA
IPC: H05B37/02
Filed: 1993-06-25
Abstract: PURPOSE:To reduce the number of operating repetition as required, and thereby enhance operability by making it possible to select switching order for lighting. CONSTITUTION:In the switching device for lighting which switches over a plurality of lighting conditions including miniature bulb full lighting L, minatrure bulb dimming M and lights out N to the scale of a switch 2 for remote control in a specified order, a lighting condition is designed to be switched over by a switch-over means 4 in the order of fluorescent light full light J   fluorescent light dimming K   miniature bulb full light L   lights out N. In this case, the operation of the switch 2 at the condition M permits switchover to be made to the condition N by a switch-over means 5, however, when the switch 2 is operated at the condition L, one of switch-over to the N and M conditions by the switch-over means 4 and 5 is suspended by a selection means 6. Selection at this time is determined by the period of time from time when switch-over has been made to the condition L to time when the switch 2 is operated, and if time is within a specified period of time, the switch-over means 5 is suspended, and if time is out of the specified period of time, the switch-over means 4 is suspended. By this constitution, if switch-over is made in an order with the condition M excluded, which has a great number of operating repetition, it is possible to reduce the number of operating repetition, and thereby to make switching operation simple.

Abstract: PURPOSE:To detect an object out of a photographed image and to decide the characteristics of said object by calculating the projected area of the object on an optional plane in a 3-dimensional space from the photographed image and discriminating the object from the actual area to which influence due to distance is corrected. CONSTITUTION:An object detecting part 1 detects an object out of an image photographed by an image photographing device. An area calculating part 2 calculates a projected area on an optional plane in a 3-dimensional space of said detected object. Then an object discriminating part 3 discriminates the object based on the projected area calculated by the part 2. The part 2 obtains the projected areas of a car 4 and a pedestrian 5 on an optional plane in a 3-dimensional space out of a photographed image 6. Then the sizes of the car 4 and the pedestrian 5 are compared with each other at the part 3. Thus the comparison is possible between both objects with the actual areas to which the distance influences are corrected. Then the car 4 or the pedestrian 5 can be decided. In such a way, an object is detected out of a photographed image and the characteristics of the detected object can be discriminated.
