Title: Heating device
Inventor: SHIMIZU MITSURU
IPC: F24C15/08
Filed: 1984-06-04
Abstract: PURPOSE:To improve appearance, to simplify cleaning and to improve mechani- cal strength of the system by forming a main body of a heating chamber by bending a metal plate and also forming one part as a heating chamber and another as a power source housing chamber. CONSTITUTION:A metal plate is bent to form the left side part into a heating chamber 2 and the right side part into a power source chamber 3. The front end surface and the rear end surface of the metal plate are bent into a substantially U-shape, and bonded to a front plate 4 and a back plate 5 by curling bonding. Bonded curling part 8 is formed from the outer periphery of the main body 1 to the inner side as viewed from the front surface. By providing a part 10 bent into a U-shape in the main body plate 1, the curling part 8 does not protrude to the outer periphery of the main body 1 but its appearance becomes smooth. Further, since the joints of respective plates separate from the corner part C of the heating chamber 2, cleaning of the heating chamber 2 becomes simple and cleanliness thereof can be maintained. Further, it is possible to improve the mechanical strength of the main body structure by the bent portion 10.

Title: Optical integrated circuit device
Inventor: SUGINO TAKASHI
IPC: H01S5/026
Filed: 1984-06-07
Abstract: PURPOSE:To form an optical integrated circuit having an inverter, to be turned to the base of a digital circuit, composed of a photo element by a method wherein an element to be used to detect a light and a light-emitting element are integrated in the state of parallel connection on a semiconductor substrate. CONSTITUTION:A light-emitting element 7 and a light-receiving element 8 are connected in parallel. When a terminal 21 is plus-biased and a terminal 22 is minus-biased, a current runs on the active layer 13 of a semiconductor laser, and a laser oscillation is generated. A photo conductive element, which is a light- receiving part 18, is connected to the semiconductor laser in parallel, but when no photo signal is inputted from outside, no current runs because the light-receiving part 18 is in the state of high resistance. Then, when a photo signal is inputted, the resistance of a high resistance layer is reduced as it is absorbed by the light-receiving part 18. As a result, a part of the current running to the semiconductor laser runs to the light-receiving part, the current running to the semiconductor laser is attenuated, and the photo output is decreased. The oscillation of the semiconductor laser can be stopped by working out the design of this device in such a manner that the voltage running on the semiconductor laser is reduced to the threshold voltage or below by the input of photo signal.

Filed: 1995-05-15
Abstract: PURPOSE: To improve measurement accuracy and maintenance efficiency and to reduce work load by providing a means for judging whether integration is proper or not and performing a specific treatment. CONSTITUTION: A free induction decay(FID) check mechanism judges whether FID obtained for each application of radio wave is suited for integration or not, sends one which is suited to an integration area (a), sends one which is not suited to an area (b), and counts the number of data at each area. When it is not necessary to store one which is not suited for integration, only the number of data is counted and deletion is made or temporary storage is selected. Data sent to the area (a) repeat application of pulses until the number of count reaches the set number of integration's and are integrated as they are.  Also, when the data which are not suited exist continuously for two times or more or when the number of non-integration's is large, a mechanism is provided to stop integration automatically, thus preventing an overload from being applied to a device due to spark noise and maintaining the device.

Title: Semiconductor memory device
Inventor: KOBAYASHI TATSUJI
IPC: G11C11/401
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To individually detect defects due to various deficient margins by shortening testing time required for detecting failure due to deficient margins. SOLUTION: In a shared sense amplifier utilizing DRAM which allows to connect a first- and a second bit line pair to one sense amplifier, the connection of the first and the second bit line pair at the time of testing mode is controlled as follows: the signal S1U which controls the connection of the second bit line pair is brought to 'H' and thereby the second bit line pair not used in usual operations is also connected to the sense amplifier by changing a newly added testing control signal ZWLF from 'H' to 'L' before the word line WL0 is selected in the process of reading data from the memory cell. Thus, the word line WL0 is selected in the condition where the bit line capacity is doubled compared with the usual operation to read data out from the specified cell. In this way when the cell capacity margin is deficient, correct data cannot be readout.

Title: Temperature controller
Inventor: MAESE YOSHIYUKI
IPC: G05D23/19
Filed: 1982-07-03
Abstract: PURPOSE:To prevent chattering and to increase the temperature control accuracy for a heat fixing device of a copying machine, a printer, etc. as well as a temperature controller of a drying device, etc., by changing the reference voltage for a fixed period after an object to be heated reaches a fixed temperature. CONSTITUTION:For a temperature controller which supplies the electric power to an object to be heated in response to the output signal of a comparator, a differentiating circuit consisting of a capacitor C1 is connected between an output terminal and a plus (+) input terminal of a comparator IC1 and in series to a feedback resistance R6. Then the differential waveform is fed back in both rise and fall modes of the output of the comparator IC1. Therefore the difference between reference voltage of the plus (+) input terminal and the voltage of the minus (-) input terminal of the IC1 becomes large. Thus the chattering of the output of the IC1 is never generated owing to the ripple of the thermistor voltage.
