Title: Setting circuit of current ratio
Inventor: SUGAWARA TSUTOMU
IPC: H03F3/347
Filed: 1981-10-16
Abstract: PURPOSE:To set a large current ratio in a simple way, by applying the bias to each base of two transistors which set the current ratio via a diode and at the same time connecting a current source to the base. CONSTITUTION:The 1st and the 2nd resistances 13 and 14 are connected to the emitters of the 1st and the 2nd transistors (TR)13 and 14. The bias is applied to the bases of the Trs 13 and 14 from a DC power supply 19 via diodes 15 and 16, and at the same time the current sources 17 and 18 are connected to these bases. The collectors of the TRs 13 and 14 serve as the 1st and the 2nd current feeding terminals respectively. Here the resistance value ratio is set at 1:m between the resistances 13 an 14, and the effective emitter area ratio is set at 1:n between TRs 11 and 12. Then the effective area ratio is set at p:1 between the diodes 15 and 16, and the current ratio is set at r:1 between the sources 17 and 18. Thus the value of each ratio is decided to satisfy an equation nXp= mXr. As a result, the current ratio I1:I2 can be set at m:1 between the 1st and the 2nd current feeding terminals.

Title: Fixing device
Inventor: MATSUDAIRA SUNAO
IPC: G03G21/14
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To set an on/off interval as long as necessary and to reduce the flicker of an illumination lamp in a room where an image forming device is installed by executing the on/off control operation of the heater of a fixing device according to time counted by a timer. SOLUTION: After an image forming action is started (S1), it is judged, based on a signal from a sensor SE detecting the fixing temperature of an upper roller fixing a toner image, whether the fixing temperature is equal to or under the control temperature t1 (S2). When it is higher than the prescribed value t1, the heaters H1 and H2 are turned off (S3). When it is equal to or under the prescribed value t1, the timer is started (S4). When the time is up (S6), the heater H2 is turned on. Then, it is judged whether the fixing temperature is equal to or under a prescribed value t2 (S8). When it arrives at the prescribed value t2, the sub-heater H2 is turned off (S11) and the timer is reset (S12). Thereafter, operation is returned to the step S2 and control routine is executed.  A step S9 is prepared in order to lower the fixing temperature when the fixing temperature becomes over the prescribed value t1 by the heating of only the heater H1.

Title: Chemical-material detecting apparatus
Inventor: ONISHI MICHIHIRO
IPC: G01N5/02
Filed: 1990-06-26
Abstract: PURPOSE:To prevent the short circuits of interdigital electrodes and to make it possible to perform table operation by coating the interdigital electrodes in contact with a piezoelectric substrate with dustproof member. CONSTITUTION:An input electrode 2 and an output electrode 3 are provided at a specified interval on a piezoelectric substrate 1 comprising a rock crystal substrate and the like. Dustproof members 5 and 5 comprising glass plates and the like are provided on the electrode 2 and the electrode 3. An input signal is converted into the surface elastic wave with the electrode 2. The wave is propagated on the surface of the substrate 1. The wave is returned into the electric signal with the electrode 3 which is separated by the intended delay-time distance. When the different kind of a chemical material (gas molecules) is incorporated into an organic thin film 4, the weight of the entire film is increased. Therefore, the phase speed of the surface elastic wave becomes slow. The oscillating frequency of a loop is decreased in proportion to the amount of adsorption. When the gas molecules are desorbed, the oscillating frequency is returned to the original value. Therefore, when the change in this oscillating frequency is measured with a frequency meter, the amount of the adsorption of the gas molecules into the thin film 4 can be detected.

Title: Optical transmission circuit
Inventor: NAGANO KATSUYUKI

Filed: 1985-07-29
Abstract: PURPOSE:To obtain an optical transmission circuit capable of detecting the abnormity of the waveform of an optical output by adding newly a waveform discriminating circuit deciding a level of a monitor waveform at a level change point of an input signal of a drive circuit. CONSTITUTION:When a high level state of an output transmission waveform of a flip-flop 10 is normal, a waveform fault detection signal 12 is obtained as a normal detection level, that is, a high level and when a waveform fault is caused, the signal 12 is obtained as a waveform abnormity detection level, that is, a low level. The above is obtained similarly at a flip-flop 14 and the level after a prescribed time elapses from the leading/trailing of the monitor waveform is compared with a reference voltage, then a waveform abnormity over a short time is detected. In using a modulation circuit 13, the quantity (pulse width fault) of distortion of the monitor waveform 9 is detected. Since the change point of the timing waveform 11 has a width by applying frequency or phase modulation to an input signal 1 of a drive circuit at the modulation circuit 13, the quantity of waveform distortion in the monitor waveform 9 is detected by selecting the modulation properly.

Title: Manufacture of semiconductor device
Inventor: IOKA SATOSHI
IPC: H01L21/3205
Filed: 1987-07-02
Abstract: PURPOSE:To suppress the contamination and the increase in foreign materials of an etching apparatus, when an aluminum film undergoes anisotropic etching, by using double-layer masks comprising a plasma oxide film and a resist film as masks. CONSTITUTION:An Al film 3 and a plasma oxide film 2 are sequentially formed on an SiO2 film 4. Thereafter, resist 1 is formed as a mask material. Then, the plasma oxide film 2 is etched. A plasma oxide film mask 5 is formed in an anisotropic shape at the approximately same size as that of the resist film 1. Then, with the plasma oxide film 5 and the resist 6 as double-layer mask materials, anisotropic etching of the aluminum is performed. Thus, a selecting ratio for the resist is made low in comparison with conventional process conditions. A gas, which is used in the aluminum etching, can be changed into a gas, in which polymerization is hard to perform in plasma. A high selecting ratio can be realized for the selecting ratio for the mask material. An Al wiring 7 is machined without size shift (side etch) for the plasma oxide film mask 5. As a result, the causes of the contamination of an etching apparatus due to deposition gas and the increase in foreign materials can be eliminated.
