Title: Detector for vertical center position on television picture screen
Inventor: NAKAHATA MITSUZOU
IPC: H04N3/227
Filed: 1978-07-20
Abstract: PURPOSE: To detect and adjust the vertical center position of a picture screen at a high speed and with high precision.  
     CONSTITUTION: While no video signal arrives from the antenna terminal after the vertically-synchronous tuning of a TV screen to be tested, the vertical free oscillation frequency of the TV chassis circuit is detected by the deflecting-yoke leakage magnetic field detection coil to obtain a difference with the center value of a vertically-synchronous tunable frequency. Next, center-position variation value Δl 1  in the vertical direction of the screen corresponding to this difference is calculated through conversion. Next, a horizontal-light pattern inserted at the vertical center position of a signal is displayed on the screen and then detected by using a TV camera to obtain shift value Δl 0  from the geometric center position of the screen and this is corrected by using Δl 1 , thereby deciding on and displaying whether the vertical center position has been adjusted into a fixed range or not.

Title: Civil engineering construction method of underground buried pipe
Inventor: ARATA OSAMU
IPC: E21D9/06
Filed: 1990-04-04
Abstract: PURPOSE:To improve the civil engineering construction work efficiency and reduce the construction cost by placing a foaming resin block in a groove formed by drilling sediment, and refilling the groove with sediment immediately, as well as disposing a pipe to be buried in a piping hole formed at the block. CONSTITUTION:A block 4 made of foaming resin capable of supporting earth pressure is placed temporarily inside a groove formed by drilling sediment, and the groove is immediately refilled with sediment, as well as a pipe to be buried is disposed in a piping hole 8 formed at the block 4.

Title: Frame open/close device for image formation device
Inventor: YAMAUCHI KOICHI
IPC: E05C17/12
Filed: 1991-04-19
Abstract: PURPOSE:To simplify the open/close operation of upper and lower frames, and ensure the upper frame to be properly locked by providing the lower frame with an open/close guide plate having a guide groove. CONSTITUTION:For opening upper and lower frames 1 and 2, the upper frame 1 is lifted. In this case, the lower end 5b of a support plate moves in a counterclockwise direction along a guide groove 7 and slides into an open state lock section B over a crest section 7b. As a result, the upper and lower frames 1 and 2 are locked in open state. In this case, the support lower end 5b is held with a bottom section between the crest sections 7b and 7c and, therefore, is not released from the open state lock section B, even if subjected to a vibration or the like. For closing the upper and lower frames 1 and 2, the frame 1 is slightly lifted to cause the lower end 5b to move over the crest section 7b. Once the lower section 5b moves over the crest section 7b, due to the lifting force, the upper frame 1 moves down of itself, due to own weight, and returns to a close state engagement section A.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To keep a stable condition over a long period of time by covering a ballast surface with asphalt emulsion and rubber powder mixed therewith, if required, at a normal temperature. SOLUTION: A surface of a new ballast or a waste ballast whose fine particle portions are removed is covered with an asphalt emulsion 2 and rubber powder 3 mixed therewith, if required, at a normal temperature and a stabilization treatment is applied thereto. By treating the emulsion 2, a sink-proof characteristic is generated and further a stable condition is maintained over a long period of time for making easy on-site maintenance work. Also, wear or fine particle condition of the ballast 1 is alleviated for keeping a stable condition of a track over a long period of time and improving durability, as well as extending the replacement time of the ballast 1 long, resulting in decrease of waste ballast.  With the application of treatment to a surface of waste ballast, moreover, reuse of the waste ballast is made possible, and through the mixing-in of the rubber powder 3 to the emulsion 2, vibration of the ballast is reduced and a sinking restraining effect is enhanced.

Abstract: PURPOSE: To achieve saving of energy resources by cyclically reusing the flush medium removed from the night soil discharged into stools after it has been washed by using the emulsion liquid containing liquid paraffin, as the flush medium for sending said night soil into a separating tank.  
     CONSTITUTION: The flush medium comprising the emulsion liquid is prepared by dissolving about 0.5W5wt% surface active agent (e.g.; sorbitan monooleate) soluble in liquid paraffin into the liquid paraffin then adding 1W10wt% water into this liquid and emulsifying the same. Next, the night soil discharged into a stool 1 is mixed together with said flush medium 2 and the mixture is sent via a diffuser 9 into a separating tank 4, where the medium 2 of specific gravity lighter than 1.0 is easily separated from the night soil and the mixture is separated into the medium 2 in the upper part and the night soil layer in the lower part. Only the medium 2 is then successively overflown to a settling tank 5 and a regenerative activating tank 8 and is mixed into the medium 2 having been purified or fortified by a regenerating device 22. It is then press-fed by a circulating pump 14 and is recirculated into a flush tank 2 whereby it is reused.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of appearance and damage to the outside wall of a flexible sheet by providing a sheet inward drawing means for drawing a flexible sheet outside wall inward on the flexible sheet outside wall when a roof is lowered. SOLUTION: Lock bracket metals 35a, 35b, 35c are integrally fitted to the interior surface of both sheet sides 26a, 26b and the rear side 26c, while hooks 36a, 36b, 36c capable of being engaged with the lock bracket metals 35a, 35b, 35c in a respectively detachable manner are tightened to respective ends 37a, 37b, 37c of a trident rubber string and a sheet inward drawing means 34 is composed of these locking bracket metals, hooks and the rubber string. Bedroom space closing can be accomplished very easily without the sheet sticking to the outside because the lock bracket metals are drawn to the center of a bedroom space by the tension force of the rubber string of the sheet inward drawing means 34 and, consequently with it, both sheet sides 26a, 26b and the rear side 26c are also drawn to the center of the bedroom space.
