Title: Machine for ground work
Inventor: OHORI MASATO
IPC: E21B3/02
Filed: 1989-07-07
Abstract: PURPOSE:To make occupying area of a machine smaller by providing a locking device between a leader mast and boom composed of a multi-articulated arms for locking both these members at optional angles for angular width and by providing, at the same time, oil-hydraulic cylinders for rise-and-fall motion to each of the arms. CONSTITUTION:The front end of a catch fork 14 is detached from the lower end of a leader mast 3 with a pin 13 pulled out and is raised up with a sub- cable hooked to its front end. Then an oil-hydraulic cylinder 8 of a locking device B is contracted so that a double-link 9 is drawn in, and thereby the lower part of the leader mast 3 is drawn toward a boom A, making the angular width narrow. The oil-hydraulic cylinder 10 for rise-and-fall motion of the boom A is extended, making the whole body of the boom A raised and, at the same time, an upper arm 7 is raised with the oil-hydraulic cylinder 11 for rise-and-fall motion of the upper arm extended. Thereby the lower end of the mast 3 is drawn and is put in upright position together with an earth auger 4.

IPC: G11B5/31
Filed: 1988-07-14
Abstract: PURPOSE:To improve packaging density by forming two coils through a wall made of an extremely thin insulating material formed mainly by sputtering. CONSTITUTION:A 2nd insulating layer 7 is formed by thinly coating all the surface of a base substance with an insulating material such as Al2O3 and TiN. The 2nd insulating layer 7 is divided to a crown part 7a formed on a 2nd resist layer 4 and a U-shaped groove part 7b formed along the inner wall of an opening part 5, which are discontinuous. Said layer 7 is formed with technique of vacuum thin film formation, concretely, vacuum deposition or sputtering, etc., is applied. Especially, it is desirable to apply sputtering with the conditions properly selected so that the insulating material is made to adhere well even to the side wall of the opening part 5. The U-shaped groove part 7b functions as an insulating wall between two coils 8a and 8b and the thickness thereof can be made small to the extent of 1mum if it is formed by sputtering. Thus, the packaging density and the number of turns of a conductive coil can be improved.

Then, the molten metal 12 is once accepted by an ingate 9, and is regulated of flow. The molten metal 12 flowing over the ingate 9 flows down on a bottom plate 3a by forming a thin layer. At this time, the molten metal 12 is cooled by a cooling box 11, and is stirred by an electromagnetic stirrer, whereby its cooling to uniform temp. is accelerated. The molten metal 12 is once accepted by a bottom end wall 3c, flows over the wall 3c, and is teemed into the space between both rolls 2 revolving in a low temp. state, whereby it is cast continuously to a thin walled ingot 12a.

IPC: B21C1/00
Filed: 1984-08-23
Abstract: PURPOSE:To improve a contact reliability as well as the reduction in a cost by performing a wire drawing work with a die on the linear core material forming a precious metal plating layer on the surface. CONSTITUTION:The plating layer 2a of the precious metal of gold, etc. is formed on the linear core material 1a which is prior to a wire drawing work. Then the wire drawing work is performed with passing the linear core material 1a through the working aperture 3a of a die 3. In this case the core material 1a is made a small linear core material 1b by the wire drawing work, also a plating layer 2a is made a thin plating layer 1b. A pinhole inside the plating layer 2a is crushed, even if any, and the plated surface 1b is smoothed and the contact reliability is improved. Due to there being no necessity of making the plating layer thicker for the generation of pinholes precious metals are economized and the cost can be reduced in addition.

Abstract: PURPOSE:To form the two-dimensional pattern of high resolution which exceeds the limit of the resolution of a projection optical system by using a photosensitive material in which latent reaction concentration has a non-linear photosensitive charateristic to the incident intensity and performing exposure plurality of times by using a broken-down and divided line pattern. CONSTITUTION:A pattern is broken down into line patterns 111, 112, 114, 115, 116 having only long lines in a horizontal direction and line patterns 121, 122, 123, 124 having only long lines in a vertical direction. Two-dimensional patterns are broken to one-dimensional patterns. After the two-dimensional patterns are decomposed into one-dimensional patterns, the decomposed one-dimensional patterns are divided so as to be able to use the technique of forming very fine patterns having a pitch which is half as large as the resolution limit of an optical system in one-dimensional pattern. Exposure is performed by using the divided one-dimensional patterns and two-photon absorbing resist. Thereby, very fine patterns which exceed the limit of the resolution of an optical system can be formed.

Abstract: PURPOSE:To decrease the number of constitutive parts and to reduce cost by enabling operations from an external information processor. CONSTITUTION:When a command is inputted from a personal computer (PC) through a connector cable to an interface circuit 22, a CPU 2 checks the command. When a copy command is inputted from the PC, it is checked whether an original to be copied is set at an original read part or not, and when it is set, the state of a recording paper sheet is checked. In this case, when there is the recording paper sheet, it is checked whether a hand set is in an onhook state or not. As the result, when the hand set is on-hooked, a response to start the copy operation is returned to the PC. Next, a normal copy processing is executed. Thus, a control panel is eliminated, and the low-priced and simply designed facsimile equipment is obtained.
