Title: Coding system
Inventor: ONOE SEIZO
IPC: H03M13/00
Filed: 1984-10-22
Abstract: PURPOSE:To obtain an error correction coding system suitable for a DC cut-off transmission line by using (k-1) bits in information bits (k) of an organization (n.k) code as information and using the remaining 1 bit as a parity check bit to an odd number bit. CONSTITUTION:A BCH(23,12) code using a BCH code, e.g., having a code length n=23 and an information point number K=12 is used as an error correction code, the 11-bit in K=12-bit is used as the information A and the remaining bit is used as an odd number parity check bit B to the A part. The A,B are used as the information bits to generate a check bit C by the generation polyno mial G(x) thereby constituting the code. In this constitution, since the B takes an odd parity when the A is all logical '0', the B is logical '1', and when the A is all logical '1', since the A is an odd bit, the B is logical '0' and all '0' or all '1' is not included, then when the error correction coding by the BCH code is applied, a circuit suitable for the CD cut-off transmission line not including the code series deteriorated in the DA balancing characteristic is obtained.

Title: Puffer type gas-blast circuit breaker
Inventor: AKUTSU KATSUNORI
IPC: H01H33/91
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the insulating material around an arc contact to eliminate part replacement, and extend the life of a device by providing a puffer piston for compressing the insulating gas in a puffer cylinder when a movable contact is separated from a fixed contact. SOLUTION: When closing a puffer type gas-blast circuit breaker, a fixed main contact(CT) 1 makes contact with a movable main CT 8, and a fixed arc CT 2 makes contact with a movable arc CT3. The capacity of a puffer chamber 4 is maximized. In current interruption operation, a movable bar 9 is quickly moved down from the closed state by a drive mechanism. Since a communicating hole 10 communicating with the chamber 4 is blocked by the engagement with CT 3, the chamber 4 is sealed, and the insulating gas in the chamber 4 starts to be compressed. When the bar 9 is further moved down, CT 1 and 8 are opened, and CT 2 and 3 are then opened. Thus, an arc 12 is generated between both contacts. When the engagement of CT 2 and 3 is released, the high pressure gas in the chamber 4 becomes a gas flow 13 blowing out from the tip of CT 3.  This gas flow is blasted between the CT 2 and 3 to stretch, cool and interrupt the arc 12 between the CT 2 and 3.

Abstract: PURPOSE:To enable most of the working fluid to pass through a bypass passage by inserting a cylindrical member to be interposed between a casing and a plunger and forming the bypass passage between an outer side of this cylindrical member and an internal surface of the casing. CONSTITUTION:When a pressure of fluid in a master cylinder side in a fluid path 7a is increased, the working fluid passes through a valve part 2 and a passage 2d, positioned in a side of a fluid in-out path 7, being allowed to flow in a wheel cylinder side of the fluid in-out path 7. Now when the pressure of fluid to the fluid in-out path 7 increases to a predetermined value or more, solenoids 4, 4 are energized closing the valve part 2 positioned in a side of a valve seat 2a and opening the valve part 2 positioned in a side of a valve seat 2b, and a pressure is relieved by allowing the working fluid to flow in a reservoir side through a bypass path 6 and a passage 2e. When a pressure of fluid in the fluid path 7a is reduced, the working fluid is returned from a side of the in-out path 7 and a path 7b passing through the bypass path 6 to a side of the fluid path 7a. In this way, the working fluid moves passing through the bypass path 6, so that no influence is given to movement of a plunger 1.

Title: Disk reproducing device
Inventor: HORI KAZUAKI
IPC: G11B19/26
Filed: 1988-09-07
Abstract: PURPOSE:To eliminate discontinuity of reproducing signals when a disk reproducing face is switched and to smoothly reproduce both sides continuously by providing a device to process and reverse a signal time-axially so as to output one part of information recorded on a disk before information fetched after. CONSTITUTION:The title device consists of a video disk 1, a disk rotating motor 2, pick-ups 3 and 4 for an A-face and a B-face, a time axis reversing circuit 13, etc. The information of the face opposite to the face being reproduced is read and demodulated while the first face is reproduced and it is outputted as soon as the information of the face being reproduced is finished. Since, at this time, the disk on the side read newly rotates in a direction opposite to a normal rotational direction, the front and rear of a demodulated signal is reversed. By reversing this signal time-axially and outputting it by the device which outputs previously the information fetched after, it is made into the same signal at the time of a normal rotation. Thus, the discontinuity of the reproducing signals when the disk reproducing face is switched is eliminated and both the sides can be smoothly reproduced continuously.

Title: Motor for blower
Inventor: YASUJIMA TAKEHIKO
IPC: H02K1/18
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To improve the durability of a motor for blower by preventing the temperature of the motor from rising, by providing an armature coil formed by alternately laminating core plates having different outside salient-pole diameters upon another. SOLUTION: The armature 1 of a motor for blower has a shaft 2 and an armature core 4 formed by press-fitting a laminated core plate in the shaft 2. The laminated core plate is formed by alternately laminating core plates 4a and 4b, the salient poles 14a and 14b of which have different outside diameters ϕA and ϕB (ϕA>ϕB) upon another. Since C-faces (C=(ϕA-ϕB)/20) are formed at (n-1) (n: the number of laminated core plates) spots on the external surface of the armature core 4, the outer peripheral surface area of the armature 1 becomes (ϕA-ϕB)×(n-1)+nt (N: the thickness of each core plate) which is larger than that of the conventional armature by (n-1)×(ϕA-ϕB)/2, because the outer peripheral surface area of the conventional armature, S, is given, S=nt.  Therefore, the durability of the motor is improve, because the contact area of the motor with air becomes larger and the temperature rise of the motor can be prevented.
