Title: Format decision circuit for character data
Inventor: SHINDO HIROYASU
IPC: H04N7/025
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To perform accurate character display on a TV screen by comparing the sizes of the counted value of a counter circuit and a specified threshold value and deciding which one of first and second formats character data superimposed in the prescribed horizontal scanning period of video signals are. SOLUTION: When the input of an AND gate 16 is TV guide positive data, a threshold value detection circuit 17 and a low value detection circuit 18 output a high level and a high value detection circuit 19 outputs a low level. Then, a first RS flip-flop outputs the low level and a second RS flip-flop outputs the high level. Thus, a rise detection circuit 27 is enabled only in the high level output period of a second window circuit 24, detects the fall of the start bit of the TV guide positive data present in the period and outputs detection pulses PRES. At the time, a fall detection circuit 25 is enabled, however, accompanying the low level output of the first RS flip-flop, can not perform a detection operation.

Title: Polyphenylene sulfide composition
Inventor: INUI SATOYUKI
IPC: C08L81/02
Filed: 1989-02-07
Abstract: PURPOSE:To prepare a resin compsn. improved in the toughness and impact resistance by compounding polyphenylene sulfide with a specific zinc oxide. CONSTITUTION:100 pts.wt. polyphenylene sulfide is compounded with 0.01-5 pts.wt. zinc oxide having a mean particle diameter of 0.01-20mum and a specific surface area of 5-100m<2> to give a resin compsn. Said zinc oxide, being obtd. by e.g. reacting zinc nitrate with ammonium liq., has specific surface area 2-30 times larger than that of a commercially available zinc oxide prepd. by a dry process wherein zinc metal is burned. Consequently said zinc oxide is active to show a catalytic effect and is capable of imparting compatibility to the polyphenylene sulfide which otherwise has almost no compatibility. Said resin compsn. can be reinforced with glass fiber, thereby being given a higher toughness than that of a conventional reinforced polyphenylene sulfide resin while retaining the same strengths as those of the conventional reinforced resin.

IPC: E02F3/40
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To lock an attachment by rotating it by the own weight by fixing a connecting metal tool fitted with a hook to a stay member pivotted to a machine body arm and hooking a support bar provided at the base end side from the gravitational center of the attachment and lifting it. SOLUTION: A structural member for fitting an attachment is constituted of connecting metal tools 3 fixed with welding or the like to stay members 2 pivotted in a civil engineering machine body 1 and an attachment 4 detachably joined to the body. A hook 5 and a guide groove 6 for engagement are formed in the connecting metal tool 3 and hooking metal tools 7 are rotatably pivotted. The attachment 4 is provided with a support bar 10 close to the side face of the base end side from the gravitational center. And an engaging pin 11 engaging with the guide groove 6 is provided. When the support bar 10 is hung by the hook 5 and the civil engineering machine body 1 is lifted upward, the attachment 4 is rotated around the support bar 10 and the engaging pin 11 is engaged with tune guide groove 6. Then, toe hooking metal toot 7 is rotated to lock it.  In this way, the attaching and detaching work of heavy attachments can remarkably be simplified.

Title: Nail, and tightened structure using the nail
Inventor: NAGAI KOTARO
IPC: F16B15/06
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a nail which is easy in driving and capable of performing firm tightening by fitting a plate-shaped metallic piece which is inclined in the diagonal direction toward a head part and elastically deformable to an outer surface of a shaft part. SOLUTION: A nail 1 is provided with one pointed end on a shaft part 2, and can be easily driven into a gypsum board 6 and a steel sheet 5 without making a prepared hole. Because plate-shaped metallic pieces 4, 4 which are inclined in the diagonal direction toward a head part 3 and elastically deformable are fitted to an outer surface of the shaft part 2, the inclined plate-shaped metallic piece 4 narrows its angle of inclination by a through hole in the steel sheet 5 pierced by the shaft part 2. Because the metallic piece 4 is elastically deformed, the restoring force to return to the original angle of inclination is exerted, the metallic piece 4 is pressed by the through hole, the resistance is increased against the drawing of the nail 1, realizing the firm tightening.
