Title: Measuring method of characteristic of solid-state image pickup device
Inventor: KINOMURA TADASHI
IPC: G01R19/00
Filed: 1984-01-19
Abstract: PURPOSE:To eliminate the influence of switching noise to be inflicted on the characteristic measurement of the titled device by detecting digitally part of the output waveform of a device which shows abrupt variation above a specific level as a switching noise of a photoelectric converting element, and processing it. CONSTITUTION:Light having a known constant level is incident on a solid-state image pickup device 7 then the photoelectric converting element is scanned to generate its output. The output is amplified and supplied to and converted by an A/D converter 8 into a digital value with a proper sampling frequency and the proper number of bits, thereby supplying the digital value to a subtracter 9 successively. This subtracter 9 calculates differences between digital signals which are supplied one after another, and supplies digital signals indicating those differences to a comparator 10. If a digital signal from the subtracter 9 exceeds its threshold value, a pulse is generated. This noise pulse appears at the output terminal 13 of an AND circuit 12. A voltmeter and other measuring instruments are connected to the terminal 13 through an integrating circuit, etc., to take an accurate measurement of characteristic from the output of the solid-state image pickup device without any switching noise.

Title: Amplifier
Inventor: SASAKI YOSHINOBU
IPC: H03F1/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To enable stable operation for not generating unwanted oscillation or the like, by temporarily changing the output characteristics of an FET by changing a gate bias by respectively outputting a prescribed single pulse from a pulse generating circuit to a gate bias circuit at rising and falling of a pulse to be inputted to a drain bias circuit. SOLUTION: At the rising and falling of a pulse voltage which is to be impressed to a drain bias terminal 11 of an amplifier 1, the voltage value of a negative voltage impressed to a gate bias terminal 8 is respectively changed by a pulse generating circuit 7, so that the gate bias can be changed. Thus, when the pulse voltage is impressed as the drain bias, a bias point can be reached without passing through an unstable area to generate oscillations or the like in the output characteristics of the FET, and furthermore, the bias point can be returned to a point to turn a drain current and a drain voltage to zero.

Title: Power controller
Inventor: NIIYAMA TORU
IPC: A47J27/00
Filed: 1990-01-18
Abstract: PURPOSE:To reduce rush current upon starting the conduction of current through a load such as a heater or the like by a method wherein the conduction of the electric current to more than two sets of load is not effected simultaneously regardless of the set value of a power setting means. CONSTITUTION:Power setting means 7 is set at full conduction at the time of starting power supply through heaters 1-3. During initial several periods, the trigger signals of two-way thyristors 4-6, which are outputted from a gate power distributor 9, are outputted one by one at every half period sequentially. Accordingly, the heaters 1-3 are energized one by one at every half period sequentially. In the case of halogen heater, for example, rush current in the initial half period is about 20 times of a rated current and, thereafter, the value of the rush current becomes same as the value of the rated current. Accordingly, the rush current upon starting of power supply through loads such as the heaters 1-3 or the like can be reduced. According to this method, affections on other instruments such as illuminating equipments or the like or the blow out of a fuse can be prevented.

Title: Production of non-steamed soybean-fermented food
Inventor: ARAI SATOSHI
IPC: A23L11/20
Filed: 1989-01-18
Abstract: PURPOSE:To economically advantageously obtain the title pale yellow food free from 'miso' odor, usable over a wide range of applications by subjecting specific coarsely ground soybean to steam in a closed vessel followed by rapid discharge into a space at a pressure below the atmospheric pressure to effect conversion to powder which is then fermented. CONSTITUTION:Soybean is coarsely ground, at temperatures below normal temperature, to a size ca.1/2-1/8 the original size, put to skin and embryo elimination, put into a closed vessel and subjected to steam of <=1kg/cm<2> for 3-20min. Thence, the resultant soybean is rapidly discharged out of the vessel at a pressure below the atmospheric pressure to effect expansion followed by conversion into powder. Hot water at 80-95 deg.C is then applied on the powder followed by addition of 'koji' and table salt to effect fermentation, thus obtaining the objective food. The reason why soybean is coarsely ground at temperatures below normal temperature is to prevent soybean protein, etc., from deterioration due to heat and/or oxygen to prevent generation of soybean odor attributable to deterioration products. And the reason why the original soybean is ground to the above-mentioned size is to enlarge the contact area with steam to sufficiently exert the expansion effect in the above-mentioned rapid discharge into the space at a pressure below the atmospheric pressure.

Filed: 1988-01-21
Abstract: PURPOSE:To provide the user with accurate data on cooking, by calculating the amounts of materials necessary for cooking, based on the amounts of the materials per unit number of persons and according to a specified number of persons, converting the amounts into values expressed in another system of units, and displaying the values. CONSTITUTION:A controlling and calculating part 13 constitutes a calculating means and a display processing part. A display part 9, an input means 11, a storage part 15 and a cooking driving part 17 are connected to the controlling and calculating part 13. At the time of displaying the amounts of materials necessary for cooking, a predetermined converting process is carried out, as required. Namely, when the amounts of materials required are stored as amounts per person, the amounts of the materials for N persons can be obtained simply by multiplication. When the calculation result is 1200g, for example, an optimum unit for the amount is kg, so that the controlling and calculating part 13 converts the value of 1200 to the value of 1.2 by using a conversion table. With the amounts of materials thus displayed as values corresponding to a required number of persions, it is unnecessary for the user to perform conversion or the like each time of cooking, and since the values are displayed in a system of units easy for the user to recognize, the user can intuitively understand the amounts of the materials required, at a glance.
