Abstract: PURPOSE:To print speedily without interruption even if a new image plane is not detected by step-carrying an original image film the distance which has already been recognized and set, by means of a carrying control part, even if the new image plane is not detected by an image plane detector, and then printing it. CONSTITUTION:The quick-type printing device is provided with the image plane detector 50, which detects the image plane of the original image film 10, and with the carrying control part 60, which controls the step-carrying distance of the original image film 10 based on the result obtained by the image plane detector 50. When the original film 10 is step-carried but its image plane is not detected by the image plane detector 50, the original image film 10 is step- carried the distance which was previously set by means of the carrying control part 60 or the distance determined by an image plane, which has already passed the carrying control part 50 and whose step-carrying distance has been detected, previous to the new image plane which is not detected; ultimately the new image plane is printed. Thus, even if the new image plane is not detected, appropriate step-carrying and printing are performed by means of a simple structure.

Title: Static induction type thyristor
Inventor: NISHIZAWA JUNICHI
IPC: H01L29/74
Filed: 1987-03-12
Abstract: PURPOSE:To obtain a static induction type thyristor especially suitable for an operation under a big electric current by a method wherein the static induction type thyristor can have an improved structure by improving the switching speed with an acceleration electric field created in such a way that an impurity slope is provided at a channel region. CONSTITUTION:An n<--> type region 19 whose impurity density is extremely low is formed so as to surround a source, and,at a place adjacent to the n<--> type region 19, an n-type region 20 whose impurity density is comparatively high and whose thickness in the cathodeanode direction is thin is formed. The impurity density of this n<--> type region 19 is low. This region 19 shows a comparatively flat potential profile, and is transformed under the influence of the potential distribution at the n-type region 20 at the anode side. In addition, within the n-type region 20 a comparatively steep potential slope is formed in the cathode- anode direction, and an electric field is generated in such a way that it strongly accelerates an electron moving to the anode from the cathode across a potential barrier. Because an intrinsic gate is formed at the n<--> type region 19 adjacent to the source region 12 and the electron which passed through the intrinsic gate is accelerated strongly, the moving time of the electron becomes short and the thyristor is quickly turned on. In addition, because the n-type region 20 whose impurity density is comparatively high is constituted so as to cover the p<+> type gate region, the voltage of a device in the forward direction can be improved.

Title: Encryption device and encryption method
Inventor: SHIMIZU HIDEO
IPC: H04L9/18
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To enhance the safety of cipher text by updating a stored content state by an internal state updating means every time encryption conversion is executed. SOLUTION: An F function 1 as an encryption conversion means receives the plaintext to be encrypted, an encryption key 5 and the internal state 6, executes the prescribed encryption conversion and produces an output 7. An internal state updating function 3 updates the internal state 6 every time the encryption conversion in an internal state storing means 2 for storing the internal state 6 and the F function 1 is executed, i.e., simultaneously with the encryption conversion. Even if the same plaintext and the cipher key are inputted, the output is changed by the updatable internal state according to such constitution and, therefore, the safety of a round function which can be an effective defense method against the differential attack based on the analysis of the input and output functions of the round function is enhanced.  The device may be composed of the round functions of a smaller number of stages when the safety of about the same degree is taken into consideration.

Filed: 1988-03-14
Abstract: PURPOSE:To obtain good-quality treated water by separating an anaerobic filter bed and an aerobic filter bed by a partition wall capable of collecting the gas generated from the anaerobic filter bed. CONSTITUTION:Sewage is introduced from the lower part of the anaerobic filter bed 1 through a raw water supply pipe 3, sent upward in the bed 1, and biologically treated. The gas generated by the anaerobic treatment is collected by the partition wall 6, and further collected by a gas collecting pipe 4. The sewage after the progress of treatment passes through a flow passage between the partition wall 6 over the anaerobic filter bed 1, and enters the aerobic filter bed 7. An oxygen-contg. gas 9 is diffused from a diffuser set below the aerobic filter bed 7, and the water is treated by the aerobes adhered to the suspended filter bed material 10. The outflow of the suspended filter bed material 10 to the outside of the system due to the gas diffusion is prevented by a suspended filter bed outflow preventing net 12 on the aerobic filter bed 7.

IPC: G01N21/31
Filed: 1993-03-19
Abstract: PURPOSE:To allow relatively quickly and accurately numeric indication of corrosion resistance to be obtained by subjecting a metallic member, which has been brought into contact with corrosive gas, to ultrasonic cleaning using pure water and then subjecting the cleaning water to atomic absorption spectrochemical analysis thereby measuring the dissolved quantity of each compositional element of the metallic member. CONSTITUTION:In a corrosive product forming process 1, a metallic member A to be tested is subjected, for a predetermined time, to a corrosive gas or solution to form a corrosive product on the outer surface thereof. The metal A is then subjected to ultrasonic cleaning 2 for a predetermined time using pure water B. Consequently, the corrosive product is peeled off from the metal A and dissolved into the cleaning liquid which is then analyzed 3 using an atomic absorptiometer. Quantities of compositional elements of the metal A dissolved into the cleaning liquid are detected automatically and delivered to an evaluation process 4 where the detected values are corrected to values under predetermined conditions based on the type of the corrosive gas, contacting time therewith, cleaning time, etc., thus calculating a value representative of corrosion resistance. Corrosion resistance of stainless steel can be evaluated by simply detecting the quantities of Cl, Fe, Cr, Ni and Mn dissolved into the cleaning liquid.
