Title: Concrete pavement steel-made form
Inventor: KUBO MASAHIRO
IPC: E01C19/29
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To shorten working hours in concrete laydown work between existing lanes by making substantially identical the level, direction and position of the top of a form with the laid out surface of a rail which supports a pavement machine. SOLUTION: A concrete pavement steel-made from 11 is formed in the shape of an integrated square cylinder and provides a plurality of insertion holes 13 for a fixing pin 12 to fix a base with a specified spacing and a plurality of hooks which support a rail 14 which is fitted in the top of the form. The form 11 is provided with an insertion blade which connects similar kinds of forms. The level, direction and position of the top of the form 11 are made almost the same as those of the laid out surface of the rail 4. In the case of spot concrete placement pavement based on this form 11, rubbing between the starting point and the ending point is easy and even so easy that a flat pavement is available.  In the case when the spot concrete placement pavement is executed between existing concrete blocks 17 and 18, their respective machine- based level adjustment is not required in forms 19 and 20.

Title: Manufacturing of armature coil
Inventor: TAKAHASHI MAMORU
IPC: H02K15/10
Filed: 1990-07-05
Abstract: PURPOSE:To prevent an insulating material at a corner from being damaged by winding an insulating tape round a portion to be formed to a corner at the overlapping pitches smaller than those at the portion other than the corner thereby giving wider overlapping allowances in taping at the corner without increasing the man-hour. CONSTITUTION:In making an armature coil, an elliptical coil 1 is first formed by using an elliptical coil former. A circular arc portion 11 at each end of the elliptical coil 1 is to be formed to tortoiseshell-shaped corners; for this purpose, a narrow insulating tape 2 less than 15 mm wide can be used for taping at two-thirds overlapping pitches, for instance. An insulating tape 2 with 19-mm width can be used for taping at one-half overlapping pitches, for example, for straight line portions 12 connecting the circular arcs 11. Lead wires 13 are required. Upon completion of taping as stated above, the whole coil is then formed to a tortoiseshell-shaped coil 3 having a corner 31. Therefore, the followability of the insulating tape is good even when forming the corner 31 by deforming the circular arc portion 11 without causing slips or damages to the insulating tape.

IPC: B27L11/00
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To efficiently dispose chopsticks or the like, by push-breaking slender bars to small pieces of specific length by a slender bar push-breaking unit, comminuting the pieces by gears of a slender bar comminuting treating machine, and softening and fragmenting the comminuted pieces by gears having different circumferential speeds of a softening and fragmenting unit. SOLUTION: A slender bar push-breaking unit has many pressing plates 16 fixed to a rotatably driving shaft 15 at a pitch of about 1 to 4 cm, and a receiving plate 18 provided at an intermediate position of the plates 16. And, a group of the plates 16 push disposable wooden chopsticks (w) disposed on a bearer 18a to tear it into pieces. The torn chopsticks (w) are dropped between gears 21a and 21b of the slender bar comminuting treating machine 3, engaged, folded, collapsed and flattened. Then, the chopsticks (w) are dropped between gears 22a and 22b of a flexible-like fragmenting unit 4. Teeth of the gears 22a, 22b are converged at their tips. The gear 22a is driven at a fast circumferential speed in the direction of an arrow f1, and the gear 22b is driven at a relatively slow circumferential speed in the direction of an arrow f2.  Thus, the chopsticks (w) are pull-torn, softened and fragmented in a shearing state.

Title: Manufacture of battery case
Inventor: TANIGUCHI ISAO
IPC: H01M50/119
Filed: 1984-08-28
Abstract: PURPOSE:To prevent any rusting of a plated steel battery case by immersing a barrel where the battery case is placed in a rust preventive solution while rotating the barrel and then drying the battery case while rotating the barrel in a low-temperature hot air drier. CONSTITUTION:Nickel plating is performed on a steel battery case after it is placed in a plastic barrel and subjected to pretreatment. Next, the plated steel battery case is washed with water and then immersed in a rust preventive solution, prepared by dissolving a rust preventive in an alcohol before adding water, while the barrel is rotated. After the barrel is taken out from the solution, the solution is wiped off and the battery case is dried in a hot air drier while rotating the barrel. As the result, a thin polyacrylic ester film remains on the surface of the steel battery case. This thin film does not influence the characteristics of the battery and completely covers pin holes formed during the plating, thereby producing sufficient rust preventing effect.

Title: Semiconductor device
Inventor: MIURA MASAHISA
IPC: H01L27/10
Filed: 1982-10-13
Abstract: PURPOSE:To obtain another semiconductor device by a method wherein a radioactive isotope which emits beta<+> or beta<-> radiation or a thin plate or a lattice of the metal is buried in each part of a gate, a source, and a drain of a semiconductor substrate, thus being decided as an electrode. CONSTITUTION:In the source 2, closest to bi-poles of the polar surface of the gate 1 and that of the drain 3, the fixed radioactive isotope or the element metal thereof is buried as the electrode in thin film or lattice form. When the beta<+> radioactive isotope 5 is contained in the source 2, position rays extinguish electrons in the source and reflect positive holes. The beta<-> type element acts reversely. Next, when such an element or the thin plate thereof is covered with an extremely thin insulation film and then buried at the same position, the electrons gather outside the insulation film which covers the beta<+> element, and disappear when the electrode is negatively biased in high degree. The beta<-> element acts reversely. Such electrodes are alternately provided in the source, the gate, and the drain. This constitution enables to hasten the access time to an RAM and an ROM and thus to largely increase the amount of memory.

Title: Magnetic head inverting device
Inventor: TANAKA SHINSAKU
IPC: G11B5/55
Filed: 1982-10-14
Abstract: PURPOSE:To prevent unstable fitting of a head and to attain the easy fabrication and miniaturization by inserting a support shaft fixed to a rotary plate to a through-hole of a head base, inserting a spring member between a spring seat of a shaft end and a head base and pressing the rotary plate to the head base. CONSTITUTION:The reversing is done quickly by operating a drive mechanism in interlocking with the detaching and switching operation of a pinch roll and turning a sector gear 23 in the arrow when the pinch roll placed at left and right sides of a magnetic head 1A is detached from a capstan shaft. Since a rotary plate 3 is pressed on the front face of a head base 5 via three steel balls 11 with the elastic force of a compressing coil spring 21, even if there exists any gap between a support shaft 7 and a through-hole 9 and the through-hole 9 is short, the rotary plate 3 is held stably at all times. Thus, the magnetic head 1A fitted to the rotary plate 3 is not tottered. Thus, no highly accurate dimensions for the processing of the through-hole 9 and the support shaft 7 of the rotary plate 3 are called for. Then, the lengths of the support shaft 7 and the through-hole 9 are shortened and miniaturization is attained.
