Title: Manufacture of polarizing plate
Inventor: TOUJIYOU TOSHIHIKO
IPC: G02F1/1335
Filed: 1981-08-03
Abstract: PURPOSE:To obtain a sticky and fixable polarizing plate for a liq. crystal display element capable of performing a whitened fixed display without applying a voltage by stretching polyvinyl alcohol with iodine adsorbed thereon and irradiating the resulting polarizer with ultraviolet rays to sublime and remove  iodine in the form of a desired pattern. CONSTITUTION:A polarizer 12 is obtd. by stretching polyvinyl alcohol and has iodine adsorbed on the whole surface. A stainless steel mask 5 having a formed desired pattern is mounted on the polarizer 12, and the polarizer 12 is irradiated with ultraviolet rays from carbon arc 6 through the mask 5 for 20min. At the irradiated part iodine is sublimed and removed, and the part is deprived of the polarizing power. Supports 3 made of cellulose triacetate are then adhered to both sides of the patterned polarizer 12, and by coating one side of the resulting polarizing plate 11 with a pressure sensitive adhesive 4, a sticky polarizing plate enabling a whitened fixed display can be formed.

Title: Capping pouring cylinder
Inventor: IIDA KATASHI
IPC: B65D47/12
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To remove a capping pouring cylinder easily from a mouth of a packaging container without reducing a fitting strength and the appearance. SOLUTION: This capping pouring cylinder made of a plastic is formed by fitting an outer cylinder 8 and an inner cylinder, both having the same axis, under pressure into a circular mouth B of a packaging container, causing a protruding stripe provided on an inner face of the outer cylinder to get over a protruding stripe provided at an open edge of the mouth, and mounting it to the packaging container. A half-cut line 20 is formed in an upwardly oblique peripheral direction from the lower edge of the surface of the outer cylinder 8, while extending up to the protruding stripe of the outer cylinder 8, preferably up to a position over the mouth side protruding stripe after the outer cylinder is fitted into the mouth under pressure. Thus, part of the outer cylinder is separately cut by means of the half-cut line 20 and, when the separate cutting portion goes over the projecting stripe, a press fitting force is reduced, and the pouring cylinder P becomes easier to be moved and can easily be removed from the mouth B of the packaging container. When the pouring cylinder P is taken out of a mold, the half-cut line is formed by being caught by a thin blade provided to the mold into the outer cylinder 8 of the pouring cylinder P. Since the half-cut line is fine, a press fitting strength is not also reduced and, further, the half-cut line is hardly visualized and its design effect is not also impaired.

Title: Synchronizing circuit of viterbi decoder
Inventor: YASUDA YUTAKA
IPC: H04L7/00
Filed: 1982-07-12
Abstract: PURPOSE:To attain the word synchronism with a decoder itself, by obtaining the increment of the maximum metric as to all phases, and setting the output of a phase shifter to a phase when the value is maximum. CONSTITUTION:A signal selecting a switch 70 downward is generated from a switching signal generator 60, when a viterbi decoder 200 starts its operation and the establishment of synchronism is started. Phase control information of the phase 1 is transmitted to a maximum value discriminator 40, a phase storage device 50 and a switch 70 at the same time and an integral maximum value m1 is detected and stored. Phase control information of a phase 2 is transmitted and an integral maximum value m2 is detected and compared with the said value m1. When it is discriminated that the value m2 is larger, a switching signal throwing the switch 70 upward is generated and the circuit makes the phase 2 to the synchronizing state and executes the Viterbi decoding.

Title: Tightening device
IPC: F16B31/06
Filed: 1992-03-30
Abstract: PURPOSE:To effectively prevent delay breaking in a tightening device which has a bolt, a nut, and a washer by forming an axially flowing magnetic flux on the bolt, and thereby reducing moving amount of hydrogen atoms H<+> in an inward direction. CONSTITUTION:In the tightening device which has a bolt, a nut, and a washer, an axially flowing magnetic flux is generated on the bolt. A Lorentz's force is applied to hydrogen atoms H<+> generated on the bolt surface through decomposition of water in a direction perpendicular to the flux flow, for moving it to the outside of the bolt. In case that the Lorentz's force is larger than attraction force generated by electric potential difference, it is possible to prevent the hydrogen atoms H<+> from entering the bolt and delay breaking phenomenon from occurring. Since flux density is increased at a stress concentrated part, the Lorentz's force is strengthened, and hydrogen entrance is prevented more effectively. It is found that the case magneticity is provided (example) shows remarkable delay-breaking preventive effect compared to the case magneticity is not provided (comparative example), when stress-time curve is obtained.

Abstract: PURPOSE:To miniaturize a tapping unit and make it possible to perform the thread cutting continuously with the other processing, by constituting the tapping unit as converting an up-and-down motion of a press upper mold into a rotary motion through a transmitting mechanism, and driving a tap through a rotary shaft which is connected to the transmitting mechanism. CONSTITUTION:A holder 13 is brought up/down according to up-and-down motion of a press upper mold 2, and a pinion 12 is also brought up/down and rotated, sequentially to the said holder 13. By this movement, a rotary shaft 161 is rotated through another rotary shaft 122 and a set of gears 121, 15, 151, 16. Then, a rotary main shaft 181 and a tap 18 are rotated through a sprocket 17, a chain 20 and anothr sprocket 19. At the same time, a compressed air 24 pushes a piston 22, and the rotary main shaft 181 and the tap 18 are pressed against the work 4. Consequently, a tapped hole is formed in the work 4 by the tap 18. As the pinion 12 is normally and reversely rotated by turns according to the up-and- down motion of the press upper mold 2, the tap 18 is also brought up/down and normally/reversely rotated by turns. In this constitution, the thread cutting can be performed simultaneously with the press processing.

The nickel iron alloy steel sheet enables to be spread into a thin sheet because of the higher strength compared to a low expansive nickel iron alloy and is reduced in the initial tension in spreading because of the low coefficient of thermal expansion. The large magnetic shielding effect is attained even in the case of working into the thin sheet and excellent picture display quality is attained. The graphitizing temp. is made higher compared to that of a low carbon steel sheet to form a graphitized film having higher corrosion resistance.

Title: Simulation method for errors in logic circuit and circuit device
Inventor: MIHIAERU BEENAA
IPC: G06F11/26
Filed: 1986-05-27
Abstract: A method for the simulation of an error in a logic circuit which comprises a bus optionally connectible to different logic levels, utilizes the assistance of input bit patterns from which output bit patterns are derived via a simulation model containing the error, these output bit patterns being compared to reference bit patterns which are valid for error-free operation. The object is a reliable recognition of an error which leads to a bus conflict, by applying different logic levels to the same circuit mode, by way of an output bit pattern which deviates from a reference bit pattern. This is achieved in that the bus, including the switch elements connecting the levels, is modeled by gate functions, whereby the undefined bus level given simultaneous connection of different logical levels is imaged into a logical "0" by a first bus model version and is imaged into a "1" by a second bus model version. Both bus model versions are respectively utilized in one segment of the simulation method.
