Title: Digital signature system
Inventor: OKAMOTO TATSUAKI
IPC: H04L9/06
Filed: 1992-08-13
Abstract: PURPOSE:To maintain excellent safty, and to reduce the quantity of communication. CONSTITUTION:A signer computes r<q>mod p from primes p, q (q is one of the factor of p-1) and random numbers r (more than 2 and less than p-1), and finds two pieces of (q) to be 1 and fixes them as g1, g2, and computes v=g1<-s1>.g2<-s2> mod p from q1, q2, and random number s1, s2, and opens p, q, g1, g2, t, v (t is a parameter showing the degree of safety) to the public, and decides s1, s2 as a personal secret key. When the signer A signs to a document M, he produces random numbers r1, r2 and computes x=g1<r1>.g2<r2> mod p and e=h (x, M) by a hash factor computing element 110, and moreover y1=r1+e.s1 mod q, y2=r2+e.s2 mod q using the secret keys s1, s2, and sends a signature(e, y1, y2) and M to an inspector B. The inspector B computes w=g1<y1>.g2<y2>.Ve mod p and judges whether w equals x or not, and when the above matters are established, he considers them to obtain the standard mark.

Title: Camera housing
Inventor: KIRA KOICHI
IPC: H04N7/18
Filed: 1990-08-17
Abstract: PURPOSE:To eliminate the need for the replacement of a sunshade cover depending on seasons by tilting the sunshade cover downward when a weight by depositted snow is exerted to the sunshade cover and decreasing the tilt angle when no weight is exerted to the sunshade cover. CONSTITUTION:A camera housing 7 is located at a 2nd position by the action of a spring 27 in the normal state when no weight is exerted to covers 15,15. Thus, a large gap is formed between the two covers 15,15 and a main body 10 to protect a camera 11 in the inside of the main body 10 from the strong sun ray at the summer season. When snow fall exists in winter, the covers 15,15 are turned in the direction of the arrow against the spring 27 by the weight of snow depositted on the covers 15,15 and the housing is placed to a 1st position. Since the covers 15,15 are tilted downward, the snow depositted on the covers 15,15 slides down the covers 15,15 and then the covers 15,15 are not deformed by the depositted snow.

Title: Manufacture of enclosed type nickel oxide-hydrogen storage battery
Inventor: KANDA MOTOI
IPC: H01M10/34
Filed: 1985-09-30
Abstract: PURPOSE:To perform assembly without using a hydrogen-containing atmosphere and make the capacity balance between a positive and a negative electrodes adequate, by putting a nickel oxide electrode in a state of overdischarge. CONSTITUTION:When an enclosed storage battery assembled from a nickel electrode in a state of overdischarge and a negative electrode of a hydrogen occlusion alloy in a state of discharge is repeatedly subjected to charge and discharge, a capacity given to the negative electrode by the charge of every cycle is all converted into the form of an active material but a capacity given to the nickel electrode by the charge of every cycle is only partly used for the discharge so that the capacity is used for the discharge on the negative electrode by only a quantity corresponding to the capacity for the discharge on the nickel electrode. For that reason, the capacity is stored on the negative electrode by only a quantity corresponding to the difference between the charge capacity and the discharge capacity until the charge and discharge efficiency of the nickel electrode becomes 100%. This is utilized to complete the preparatory charging of the negative electrode when the charge and discharge efficiency of the nickel electrode has become 100%. An adequate capacity balance can thus be secured for the storage battery.

Title: Psk delay detection demodulator
Inventor: OISHI YASUYUKI
IPC: H04L27/22
Filed: 1990-08-18
Abstract: PURPOSE:To allow the demodulator to easily cope with burst operation and to attain stable locking in a short period of time by increasing gradually a loop time constant according to a filter characteristic control variable as the progress of clock locking. CONSTITUTION:Information relating to an offset obtained from the output of an offset information extraction means 4 is fed to a local frequency generating means 1 as its control variable via a filter means 5 having an integration function to control the lock frequency of the clock. A filter characteristic control means 6 controls a block with respect to the filter means according to the filter characteristic control variable as the progress of the clock locking gradually. Thus, at the beginning of the clock locking, the extracted offset is quickly responded to, the block according to the filter characteristic control variable is extended in parallel with the decreased offset and the local frequency outputted from the local frequency generating means 1 is made more stable.

Title: Integration circuit
Inventor: SHIBAGAKI TARO
IPC: H03H11/04
Filed: 1985-09-30
Abstract: PURPOSE:To apply excellent integration without deviation or spike noise by separating a wiring pattern from an output terminal of a current source to a bonding pad and a wiring pattern from an input terminal of a buffer to the bonding pad in the vicinity of the bonding pad. CONSTITUTION:The wiring path from the output terminal of a current circuit 3 to an integration capacitor 9 and the wiring path from the input terminal of a buffer 4 to the integration capacitor 9 are separated completely. When a rectangular waveform current is supplied from the current circuit 3, a deviation and a spike noise due to the voltage drop across a resistor R1 and an inductance L1 are caused at the output terminal of the current circuit 3. Since one terminal of the integration capacitor 9 is connected to common, the potential at a point B is not subject to the effect of the said voltage drop and an ideal integration waveform rising gradually as the current supply is obtained. Thus, even when the integration circuit is changed at a high speed, an output without any spike noise and nearly equal to the ideal integration waveform is obtained from the buffer 4.

Filed: 1990-08-17
Abstract: PURPOSE:To provide efficient cutting by cutting a pipe raw material where plural cutting tools supported so that their rotation can be driven are held at a bore chuck mechanism, by the amount of pipe wall thickness. CONSTITUTION:In cutting a pipe raw material P0, when a bore chuck mechanism 10 is covered with the pipe raw material P0 and a holding jaw 16 is protruded from a body 15 by driving a core 19, the approximately whole pipe raw material P0 is chucked uniformly. Cutting is performed by cutting plural rotating cutting tools by the amount of pipe wall thickness. The whole periphery of the pipe raw material P0 comes into contact with both parts of up-cut ranging from the outside diameter side of the tool to inside diameter side of the tool. The burrs generated by down-cutting are removed by up-cutting and the burrs generated by up-cutting are removed by down-cutting respectively, so it is possible to prevent burrs from occurring on a cutting edge pulling side.
