Filed: 1978-12-15
Abstract: PURPOSE: To reduce remaining output by forming narrow magnetic paths in several places in the circular magnetic core, while placing shields made of circular magnetic body concentrically to the magnetic core.  
     CONSTITUTION: Laminated circular magnetic core 1 is housed in magnetic-core housing body 2.

Title: Narrow groove submerged arc welding method
Inventor: MORIGAKI OSAMU
IPC: B23K9/18
Filed: 1978-12-19
Abstract: PURPOSE:To permit the captioned welding of extra thick plates of thickness 30mm or more through one layer one pass with good efficiency without requiring any special device by specifying the melt point, groove width and groove angle of the fused submerged arc flux to be used. CONSTITUTION:First, the flux of 1300 deg.C or more in the melting point measured in air is used. Below this, the removal characteristic of slag becomes extremely poor. The kind of the submerged arc flux is of fusion type and with the bond flux base, slag removal characteristic becomes defective. Next, the groove width is made 6 to 25mm. Below these, high temperature cracking occurs and slag removal characteristic degrades. Beyond these, it is no longer narrow groove and is undesirable in terms of weld member quality. The groove angle is made up to 20 deg. and above this the advantage intrinsic to narrow groove welding method is lost with plates. Here, the effect in the narrow groove method performance is virtually none at cumulated thickness of 30 or less.

Abstract: PURPOSE:To improve durability and operational reliability of an actuator by providing the actuator in the nonrotational part near to a rotational difference sensitive coupling, and also by arranging a push rod and a spool in the axial position of a turning shaft. CONSTITUTION:When a relative rotational speed difference is caused between a first turning shaft 15 and a second turning shaft 16, a discharge flow rate is converted into a fluid pressure in accordance with the relative rotational speed difference by the flow regulation through an orifice 100.

Filed: 1992-06-16
Abstract: PURPOSE:To eliminate an erroneous detection of the remaining water in a bathtub due to drop of water of a circulation tube at the time of draining the bathtub in the case of filling the bathtub with hot water and to eliminate a deviation of a hot water filling level. CONSTITUTION:A water level monitor 17 is provided. When it detects in a predetermined sequence that a water level in a bathtub 7 is higher than a circulation adapter 8, it turns ON a water level signal, then monitors a water level, and turns OFF the water level signal when the level is lower than a reference level.
