Title: Voltage converter
Inventor: YAMAMURA TETSUHISA
IPC: H02J7/00
Filed: 1991-08-22
Abstract: PURPOSE:To provide a voltage converter stably converting even low input voltage into a constant output voltage. CONSTITUTION:An output from a battery 20 is boosted by first and second booster circuits 21, 22, and smoothed by a smoothing circuit 31. A process up to the constant output voltage after the start of voltage conversion is converted by the first booster circuit, and a subsequent process is converted by the second booster circuit. The output voltage of the smoothing circuit 31 is compared with first reference voltage by a first comparison circuit 35, and the integrating circuit of a second comparison circuit 37 is started by an output from the first comparison circuit. The charging voltage of the integrating circuit is compared with sawtooth waves STW generated from an oscillation circuit 43, and a signal forcibly interrupting the MOS transistor 29 of the second booster circuit is led out. On the other hand, error voltage between an output from the smoothing circuit 31 and second reference voltage is amplified by an operational amplifier 48, and compared with sawtooth waves, an output form the operational amplifier is synthesized with an output from the second comparison circuit, and the MOS transistor 29 is pulse width-controlled, thus acquiring the constant output voltage.

Title: Laminated film
Inventor: OTONARI SATOSHI
IPC: C08J5/18
Filed: 1988-09-19
Abstract: PURPOSE:To improve surface properties of a fine cell-containing film, particularly smoothness and bonding properties by laminating a polyester film of density larger than the specific value on one or both surfaces of a polyester film containing a number of fine, closed cells and having density in the specific range. CONSTITUTION:A film layer (layer B) almost not containing any fine, closed cells is laminated on one or both surfaces of a film layer (layer A) containing a number of fine, closed cells. It is essential that the density of layer A is in the range of 0.40-1.30g/cm<3>, preferably in the range of 0.50-1.20g/cm<3>. Also, the density of layer B should be larger than 1.30g/cm<3>, preferably in the range of 1.35-1.50g/cm<3>. When the density of layer A is beyond 1.30g/cm<3>, the content of closed cells is small and improving effect to slack aging generated by the own weight of film is almost not recognized, with is not preferred, while, on the other hand, when 0.40g/cm<3> or less, the mechanical strength of film is remarkably lowered. Also, when the density of layer B is less than 1.30g/cm<3>, the smoothness of the film surface is worsened.

Title: Treatment of waste water
Inventor: ISHII NORITERU
IPC: C02F1/52
Filed: 1986-10-03
Abstract: PURPOSE:To reduce the consumption of an inorg. flocculant and to remove COD, BOD, etc., with high efficiency by adding an iron-based flocculant to industrial waste water to previously regulate the pH of the waste water, and then adding an aluminum-based flocculant to regulate the pH of the waste water. CONSTITUTION:An iron-based flocculant such as iron polysulfate and ferric chloride (material contg. trivalent iron is preferable) is added in an appropriate amt. to industrial waste water with highly variable qualities to previously regulate the pH. An aluminum-based flocculant such as aluminum sulfate and PAC is then added to control the pH. When the pH of the waste water is adjusted to 4.5-6.5, the rejection ratio of COD can be increased, and the variations in the water quality can be coped with. Besides, coloration is reduced by the joint use of the iron-based and aluminum-based flocculants as compared with the case where the iron-based flocculant alone is used, the rejection ratio of COD is also increased by 5-15%, and the treating cost is decreased.

Abstract: PROBLEM TO BE SOLVED: To prevent a misjudgment caused by air bubbles by comparing such data as the maximum value of each region, the degree of roundness, and the degree of sharpness with air bubble criterion data and judging the presence or absence of the air bubble region. SOLUTION: Two-dimensional image data S obtained from an inspection target are sliced by threshold region separation circuits 41 and 42 using two high and low thresholds and the degree of sharpness of each region is obtained by a ratio RSL operation circuit 50 from an area difference between the slice levels of each region being separated. Also, the degree of roundness at the slice level of each region is obtained by operation circuits 51 and 52 of the degree of roundness. Further, the maximum value of each region is obtained by a maximum value detection circuit 47.  Such data as the obtained maximum value, the degree of roundness, and the degree of sharpness are compared with air bubble criterion data to judge to see if any air bubble region exists in each region and a pattern is judged by a particle pattern judgment circuit 55 from data where the two-dimensional image data of the air bubble region are deleted from the image data S when the air bubble region exists.

Title: Intake device for engine
Inventor: UCHIDA MASAHIRO
IPC: F02F1/24
Filed: 1993-08-27
Abstract: PURPOSE:To prevent shadow from being generated below a center intake valve when an intake device is constituted by using three intake valves per cylinder. CONSTITUTION:The inclining angle alpha of a center intake valve 11 is set to an angle beta or more. The angle beta is set as an angle formed of a virtual line P passing an ignition point 26 and the end point 11c of a valve body bottom surface, and a virtual line C2 which is directed from a cylinder axial core to the end point 11 and being perpendicular to a cylinder axial line C. Since all surfaces in the bottom surface of the center intake valve 11 are exposed in relation to the ignition point 26a, a shadow part is not generated at the time of ignition. It is thus possible to prevent generation of non-combustible gas so as to improve combustion efficiency, since flame is transferred to the center intake valve along all ranges of the bottom surface thereof at the time of ignition.

At the same time, an automatic change-over switch 21 is switched to a subsidiary temperature regulator 13 side terminal 21b and the temperature regulator 13 is started automatically. A subsidiary temperature setting device 22 compares liquid temperature detected by a connected subthermistor 26 and set value, and when the liquid temperature is lower than the set value, turns a subsidiary automatic switch 24 on, and turns a subheater 25 connected to the switch 24 on and heats the liquid 5 to the set value. When the liquid 5 becomes the set value, the subsidiary automatic switch 24 turns the subheater 25 on and off at period set by a subtimer 23, and the liquid temperature is maintained at nearly the set value.
