Title: Ingot cutting method
Inventor: ASANO TAKEHIRO
IPC: B28D5/04
Filed: 1989-04-21
Abstract: PURPOSE:To facilitate removing a wire, not to damage a multi-groove roller or the wire, to eliminate disconnection of the wire, and to obtain a product having high precision by lowering and cutting an ingot, which abuts on a horizontal part of the wire, together with soaking the cut part in an abrasive grain liquid. CONSTITUTION:If an ingot 13 is gradually lowered, running a wire 11 in the arrow-marked direction through the rotation of multi-groove rollers 12a to 12c, the cutting process of the ingot 13 is advanced, owing to the action of both the wire 11 and the abrasive grain liquid 17 in a storage tank 16. In this case, because of the surface tension, the surface of the abrasive grain liquid 17 stays higher than the upper end of an opening of the storage tank 16, and moreover the wire 11 has an angle of deflection theta. Therefore, the part of the ingot 13, cutting work to which has been completed, is constantly soaked in the abrasive grain liquid 17. In addition, the cutting groove, is formed on the ingot 13, opens downward and consequently the inside of the groove is always filled with the abrasive grain liquid 17. Therefore, fine abrasive grains, which are produced through the cutting work, flow into the abrasive gain liquid 17 and never cohere or consolidate within the cutting groove.

IPC: E02D7/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To drill first, second and third holes in sequence by means of a single- axis drill having a drill casing and an auger screw for drilling holes that are continuous in the form of columns, in such a manner that even if boulders are present in the ground, they are cut and removed without pushing them away into already drilled holes. SOLUTION: A first drilling process is performed and thereafter an inner casing 4 is inserted into a drill casing 2 so that the arcuate recessed portion 4b of the casing 4 faces a second drilling position. Then the drill casing 2 is drawn out with the inner casing 4 left behind, and a second drilling process is performed whereby a hole partially overlapping with the hole drilled by the first drilling process is formed. Next, the inner casing 4 is drawn out and inserted into the drill casing 2. Then the drill casing 2 is drawn out with the inner casing 4 left behind and a third drilling process is performed whereby a hole partially overlapping with the hole drilled by the second drilling process is formed. The holes that are continuous in the form of columns are thereby drilled.

Filed: 1991-02-06
Abstract: PURPOSE:To improve cooling efficiency by giving a flow direction of making a round in a lower part deck by a partition to cooling water advanced into the lower part deck which divides a lower internal part of a cylinder head by a partitioning wall. CONSTITUTION:A partition 15 is formed so as to isolate a through-hole 12 from a large window hole 13, in a lower part deck 10 which divides a lower internal part of a cylinder head 1 by a partitioning wall 9. Cooling water, which cools a cylinder 2, is advanced into the lower part deck 10 from the through hole 12 to flow such as circulating in the lower part deck 10 as shown by an arrow mark by existence of the partition 15, and the cooling water passes through the large window hole 13a to flow into an upper part deck 11. Here, the cooling water is partly advanced into the upper part deck 11 from a small window hole 13b when the cooling water makes a half round in the lower part deck 10. Thus by eliminating hesitation of the cooling water in the vicinity of a bottom surface of the cylinder head 1, cooling efficiency can be improved.

Title: Floatless liquid level relay
Inventor: KOSAKA SHIGEO
IPC: G05D9/12
Filed: 1983-06-10
Abstract: PURPOSE:To prevent incorrect display and malfunction by connecting a delay circuit to be actuated at the connection of a power supply between a liquid surface detecting circuit and an output relay circuit. CONSTITUTION:A load circuit such as a light emitting diode LED4 in the output relay circuit CR3 is driven by detecting signals from the liquid level detecting circuit BD'2 and a switch SW. At the connection of the power supply, a delay circuit TM for holding a switching element Q1 at OFF status for a prescribed period is connected to the output relay CR3. In case of detection of a water level, a thyristor SCR3 is disconnected at the rise of the water level in a water tank, so that a light emitting element in a photocoupler PC is turned off. Consequently, the switching element Q1 is turned on, a relay RY3 is excited and a light emitting diode LED4 is turned on. Although the thyristor SCR3 is disconnected immediately after turning on the power supply, voltage application to the switching element Q1 is delayed by the delay circuit TM and incorrect display is not generated.
