Title: Nonaqueous secondary battery
Inventor: NAKANISHI KUNIYUKI
IPC: H01M10/05
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a secondary battery having high capacity and superior cycle characteristic by providing a positive electrode made of a sintered body formed of a positive electrode active material, and a negative electrode that is made of a sintered body containing silicon and carbon material, contains a specific quantity of silicon in the sintered body and stores a specific quantity of lithium when fully charged. SOLUTION: Silicon content in a negative electrode sintered body is 50-99 wt.%, and the sintered body stores lithium equivalent to 200-800 mAh per gram of silicon when fully charged. Thereby, irreversible capacity is lowered and a cycle characteristic is improved, while securing high capacity as compared with a conventional carbon material. The breakdown in the structure of the negative electrode containing silicon considered as a cause of the irreversible capacity and the production of a substance not participating in a charge-discharge reaction are restrained, and high conductivity is imparted to the negative electrode.  The silicon may be crystalline or amorphous, and as a silicic compound, an inorganic silicon compound such as silicon oxide or an organic silicon compound such as a silicon-containing high polymer compound, which is a material to be changed into silicon by being decomposed or reduced in a non-oxidative atmosphere can be cited, and silicon (elemental substance) is particularly preferable.

Title: Deodorizing method for dehydrated sludge cake
Inventor: YOSHIKI JUNICHI
IPC: C02F11/00
Filed: 1988-03-02
Abstract: PURPOSE:To prevent generation of methyl mercaptan and methyl sulfide by using a powder sterilizer as a deodorizer, thereby transferring the deodorizer to a cake side after dehydration and anaerobically decomposing org. matter. CONSTITUTION:The powder of 1,2-benzoisothiazolone (one kind of the deodorizer) is suspended in water and is added in this state from a line 2 to a mixture composed of the first settling basin sludge of sewage, the excess sludge of activated sludge and the withdrawn sludge in an anaerobic digestion treatment of the excess sludge; thereafter, a high-polymer flocculating agent is added from a line 3 to the mixture to form flocs which are then supplied to a belt press type dehydrator 4 and are thereby dehydrated. As a result, the 1,2- benzoisothiazolone migrates to the cake side after the dehydration, thus exhibiting strong restraining power to septic bacteria and sulfate reducing bacteria. The org. matter is thereby anaerobically decomposed and the generation of the methyl mercaptan and methyl sulfide is prevented; in addition, the sulfate is reduced to prevent generation of hydrogen sulfide.

Title: Interrupt circuit
Inventor: HODAKA KAZUO
IPC: H03M1/12
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To improve response of A/D conversion. SOLUTION: A selection circuit 2 is connected to generating points of voltages V1, V2 in a series resistor 1 according to a control output of a control circuit 3. That is, a reference voltage is limited to be within a range between the voltage V1 and the voltage V2. When a voltage of an analog signal is within a range between the reference voltage V1 and V2, an RS flip-flop 7 is set by an output of logical value '1' of an AND gate 6 and outputs an interrupt request signal. The control circuit 3 receives the interrupt request signal to conduct a control operation and outputs a reset signal for the RS flip-flop 7, after the end of the control operation. Thus, the RS flip-flop 7 again goes into an interrupt waiting state.

Title: Original reading system
Inventor: OOTA SHIYUUICHI
IPC: H04N1/12
Filed: 1979-04-28
Abstract: PURPOSE:To realize the high-speed reading by keeping the original stand still while the reading head is giving the main scanning within the effective reading screen width and shifting the original otherwise. CONSTITUTION:When carriage 2 shifts toward the arrow and then reaches the tip of the effective reading screen width, detector 2c detects slit 1s of plate 1 to generate signal LS1. Then when detector 2c detects slit 1e, the driving direction of motor 3 is inverted. At the same time, the original shifting roller turns, and thus original A starts to shift toward arrow A. On the other hand, carriage 2 returns to the home positon in a high speed. And the speed of the motor is reduced when detector 2c detects slit 1s again. The carriage at its home position is detected by detector 5, and is then stopped. After stopping, carriage 2 starts again by the next data request. Thus the high-speed reading is realized. Also the signal of original detector 4 is extracted by signal SL1 generated then, and accordingly the termination of original A can be detected assuredly.

Title: Color display device and production of this color display device
Inventor: SUZUKI HIROYUKI
IPC: G02F1/1335
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a color display device having a good display grade. SOLUTION: Light shielding films 36 are arranged between color filters 5 and 5. These light shielding films 36 are formed into a two-layered structure. The refractive index and attenuation coefft. of the first layer 36a are made small. As a result, the low reflectivity of the first layer 36a is assured and the display grade is not impaired even if the layer is irradiated with light from an observation side (the side of Fig. A). The light shieldability is assured and the contrast of the images is increased by making the refractive index and attenuation coefft. of the second layer 36b larger. These layers 36a, 36b are formed by the carbooxide of the MoTa alloy of the same quality, by which the etching property in the production stages is made uniform and the occurrence of the difference in level between both layers is suppressed.
