摘要:
An increase in safety from attacks by use of hardware-like methods by small-sized hardware is achieved. An encryption processing device includes a logical circuit capable of programmably setting logics for executing cipher processing, a memory that stores plural pieces of logical configuration information corresponding to an identical cipher processing algorithm, and a CPU that selectively sets plural logics corresponding to an identical cipher processing algorithm in the logical circuit. Even in processing using an identical cipher key, by changing the logic of the logical circuit for each processing, power consumption in cipher processing can be varied, and places a timing in which malfunctions occur can be varied. Moreover, an increase in the scale of hardware for realizing plural logics can be curbed.

The present invention relates to a process for producing ethanol by carrying out the following steps: performing enzymatic saccharification of pre-treated lignocellulosic biomass in a reaction system; performing ethanol fermentation of fermentable sugars obtained from the saccharified pre-treated lignocellulosic biomass in the same reaction zone as the enzymatic saccharification; distilling ethanol directly off from a reaction treatment liquid in the reaction zone, so as to recover the ethanol. The process suitably uses an ethanol producing apparatus including: one reaction vessel having a biomass raw material inlet, a diastatic enzyme inlet, and a fermentation microorganism inlet; heating means for adjusting a temperature inside the reaction vessel; pH controlling means for controlling pH inside the reaction vessel; stirring means for stirring a liquid inside the reaction vessel; and distilling means for distilling the liquid inside the reaction vessel, which distilling means is directly connected to the reaction vessel. Hence, the present invention enables efficient production of ethanol from the lignocellulosic biomass with simple operations.

A ferrule for a connector of an optical fiber, which can be joined in short time with the optical fiber and can position the optical fiber securely, and a method of welding the ferrule and the optical fiber are provided. Projections 20 for contacting with a surface of an optical fiber 31 are disposed, preferably at equal intervals, along a circumferential direction of an inner wall 35b of a through hole 35a of a ferrule 35. By inserting the optical fiber 31 into the ferrule 35, and by heating and melting the projections 20 and an inner cover 33 of the optical fiber 31 by ultrasonic vibration, the optical fiber 31 and the ferrule 35 are joined together.

This invention provides a voltage controlled oscillator that improves the linearity of frequency variable characteristics and increases the range of frequency that can be varied by a control voltage. A resistor circuit is connected between a piezoelectric resonator X and an oscillator circuit. The resistor circuit includes a plurality of oscillation-amplitude adjusting resistors Rs1 to Rsn and corresponding switches SW1 to SWn. The resistor circuit adjusts the amplitude of oscillation. When a control voltage Vc applied to a varactor Cv is at a low potential, clipping by a forward voltage of the varactor Cv is suppressed, and the frequency is linearly changed by the control voltage Vc within a range of a low potential to a high potential.

Disclosed is an improved surface discharge element comprising a dielectric substrate having a discharge electrode on one surface and an inductive electrode on the other surface of the substrate, at least said discharge electrode being of a thick film conductor including conductive powder and lead-free glass as main constituents. The lead-free discharge electrode is physically resistive to erosion by electric discharge, and accordingly it can have an elongated life in use.
摘要:
A drainage pump has a pump body, a vane, a ring, and a circumferential wall. The pump has a cylindrical small vane pump chamber and a large vane pump chamber extending from and communicating with the small vane pump chamber. A suction inlet communicates with the small vane pump chamber and a discharge outlet communicates with the large vane pump chamber. A chamber slope portion is formed between the small vane pump chamber and the large vane pump chamber. The vane is adapted to be driven by a motor and is rotatably mounted to the pump body. The vane includes a large vane portion received in the large vane pump chamber and a small vane portion extending from the large vane and received in the small vane pump chamber. The small vane portion and the large vane portion rotate together when driven by the motor. A vane slope portion is formed between the large vane portion and the small vane portion. The ring has a central opening, positioned between the large vane portion and the small vane portion. The small vane portion extends through the central opening. The circumferential wall surrounds the periphery of the large vane portion and extends upwardly from the ring. The ring covers the lower end of the large vane portion. The circumferential wall collides against any drainage water returning from the discharge outlet into the pump body to absorb shock and prevent the drainage water from returning directly to the pump body from the discharge outlet.
