Title: Manufacture of structure for electric apparatus
Inventor: NOTO ATSUSHI
IPC: C04B33/28
Filed: 1988-06-20
Abstract: PURPOSE:To enable a structure such as a chassis base to be manufactured easily and inexpensively by involving a process of preparing a slurry by mixing powder of a ceramic material, powder of a glass material, and a binder and a process of sintering a molding of the slurry to thereby give the vibration proof effect equivalent to fine ceramic. CONSTITUTION:A slurry is prepared by mixing powder of a ceramic material, powder of a glass material, and a binder. After adding, as necessary, a dispersion medium to the prepared slurry to control its viscosity, the slurry is made into a desired form, sintered by heating at a glass melting temperature, and naturally cooled. The powder of a ceramic material to be used includes alumina (Al2O3) and zirconia (ZrO2), while the powder of a glass material to be used includes lead glass or borosilicate glass. Since the powder of a ceramic material is bound by sintering the powder of a glass material in this way, it is possible to fabricate a structure including a chassis base easily and inexpensively.

Title: Camera
Inventor: SUZUKI TAKESHI
IPC: H04N5/235
Filed: 1992-05-19
Abstract: PURPOSE:To provide a camera which is suitably applied to the continuous shooting actions by performing a compressing action during the exposure time if the exposure time is longer than the compression processing time and therefore increasing the record processing speed. CONSTITUTION:A record processing procedure is shown in a diagram when the exposure time is longer than the compression processing time. That is, an exposure action is started in response to the next vertical sychronizing signal VD after the input of the first sheet trigger. When the exposure is through, the data are read out of a CCD and compressed. The exposure action of the second sheet is started in response to the next signal VD after the trigger of the second sheet is inputted. The data on the first sheet read out of the CCD are compressed during the exposure period of the second sheet. When the exposure of the second sheet is complete, the data on the second sheet are read out of the CCD and then compressed. In other words, the trigger input of the second sheet is permitted immedaitely after the data on the first data are read out of the CCD. Thus the record processing speed is increased.

Title: Method for removing photoresist film
Inventor: TAKAYAMA YUICHIRO
IPC: G03F7/42
Filed: 1989-06-14
Abstract: PURPOSE:To prolong the life of a reaction liquid by using an aq. soln. of peroxysulfuric acid as a photoresist removing liquid and adding a peroxysulfuric acid to this soln. CONSTITUTION:An exothermic reaction takes place and the nascent oxygen is generated when the peroxysulfuric acid (H2SO5) is dissolved in water (H2O). This oxygen decomposes the photoresist film consisting of (C, H) into carbon dioxide (CO2) and the water (H2O). The number of the water molecules does not change before and after the reaction in this reaction and, therefore, there is no effect of diluting the peroxysulfuric acid liquid by this reaction at all and the oxidation effect is maintained by the addition of the peroxysulfuric acid. The life of the reaction liquid is prolonged in this way.
Patent JP-S5575036-A (JP)
Title: Liquid plug generator
Inventor: TEGLUND LARS
IPC: E03F7/00
Filed: 1979-11-22
Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.

Title: Triangular wave generating circuit
Inventor: KUMAMOTO SHUICHI
IPC: H03K4/06
Filed: 1988-06-20
Abstract: PURPOSE:To set the error value at zero and to obtain a plus-minus symmetrical triangular wave output with a triangular wave generating circuit consisting of a rectangular wave generating circuit and an integration circuit by detecting the output error value of the integration circuit via an integrator and returning the detected error value to the input side of the integration circuit with coincidence secured between the direction and the volume so as to secure negative feedback. CONSTITUTION:An integrator 10 consists of an operational amplifier 8, a resistance R6 and a capacitor 9 and an inverse amplifier 12 consisting of the resistances R7, R8 and an operational amplifier 11 is connected to the output side of the integrator 10. The error value epsilonof the output of an integration circuit 7 is detected as the output voltage (a) of the integrator 10. Then the value epsilon is sent back to the input side of an operational amplifier 5 with coincidence secured between the direction and the volume of the value epsilon so that the detection value of the integrator 10 is negatively fed back via the amplifier 12. Thus a closed loop is formed so that the value epsilon is always equal to zero in terms of a short time. Then a plus- minus symmetrical triangular wave is obtained. Furthermore the time constants of the R6 and the capacitor 9 are extremely increased compared with those of a resistance R5 and a capacitor 6. Thus it is possible to eliminate the variance of a slow time constant, i.e., the offset, the drift, etc.
