Title: Blower
Inventor: KIDA TAKUMI
IPC: F04D29/38
Filed: 1993-10-20
Abstract: PURPOSE:To restrain disturbance of a flow on the negative pressure surface side of a blade outer peripheral part by smoothly connecting the nearly circular- arc chamber part of a blade outer peripheral end part to a nearly circular-arc rib provided on the outer peripheral part negative pressure surface side. CONSTITUTION:A circular-arc rib 9 is provided on the outer peripheral part negative pressure surface side 5b2, and the circular-arc rib 9 is smoothly joined to the circular-arc chamber of the pressure surface part of the outer peripheral end part 8 and the outer peripheral part negative pressure surface side 5b2. Thus, when an air current W1 enters from the pressure surface side to the negative pressure side, the air current W1 enters smoothly from the circular-arc chamber of the pressure surface side of the outer peripheral end part 8 to the rib 9 of the negative pressure surface side, and the flow of an air current having strong radial component is restrained by the circular-arc rib 9 of the negative pressure surface side 5b2. Accordingly, it is possible to restrain increase in blowing noise due to the disturbance of a flow generated in an impeller 3.

Title: Terminal equipment for optical communication
Inventor: MATSUO TETSUHARU
IPC: H04L12/40
Filed: 1987-10-15
Abstract: PURPOSE:To prevent the whole system from being stopped when an abnormality is generated by always monitoring a branch light outputted from a branching device, deciding that a terminal equipment is abnormal, when lighting has continued for the time which cannot be continued logically, and detaching it from a transmission line. CONSTITUTION:When a light emitting element 11 is lighted, a branch light is outputted from a branching device 14. This branch light is converted to an electric signal by a light receiving element 15. The continuation time of this signal is counted in a monitoring circuit 16. When its count time has exceeded the time which is set, based on the longest lighting time of the light emitting element at a normal time, a detaching command signal from a transmission line flows to a terminal 13 from the monitoring circuit 16.

Title: Packaging of electronic parts by reflow soldering
Inventor: NAKAOKA YASUYUKI
IPC: H01L23/50
Filed: 1987-10-15
Abstract: PURPOSE:To avoid bridge formation by making at least the edge of a lead terminal connection upward to attract the melted solder between the lower surface of the edge and the opposing land section by meniscus thus controlling the flow at melting. CONSTITUTION:An edge 12 of a connection 6 of a lead terminal 5 is bent upward. After am electronic part 4 which is provided with such a lead terminal connection is mounted on a substrate 1 then heated by steam, a cream solder 3 melts. The cream solder 3 flows to complete meniscus; however, it is also absorbed by the rising-up edge 12 of the connection 6 thus controlling defective bridge formation by controlling the flow from the land edge to the root of the connection 6. It is permitted to bend the connection 6 from its center instead of bending only the edge of connection 6. In this case, the bending angle is small. The connection 6 can be thus bent at a position close to its root.

Filed: 1994-10-27
Abstract: PURPOSE: To realize high density recording of data onto an optical disc by forming a focusing beam providing a circular recording mark. CONSTITUTION: A pair of piezoelectric elements 3, 4 are arranged under an objective lens actuator 2. The piezoelectric elements 3, 4 are arranged in the tangential direction of an optical disc at an interval L and driven differentially, at the time of recording, to incline the objective lens actuator 2 by a predetermined angle θin the tangential direction of the optical disc. A focusing beam is set to have a predetermined 'riceball' shape at that predetermined angle θ. A tear drop shaped recording mark, to be formed by the thermal response characteristics on the surface of the optical disc, is set to be circular when the focusing beam is circular. At the time of recording, a predetermined voltage is applied to the piezoelectric elements 3, 4 to incline the objective lens actuator by a predetermined angle thus recording data so that the recording mark will be circular.  At the time of reproduction, no voltage is applied to the piezoelectric elements 3, 4 and the data is reproduced with a normal circular focusing beam.

Abstract: PURPOSE:To prevent an inflow of high frequency voltage to a car body the time of plug discharge effectively, and to reduce and obviate the noises of a car radio by discharging high frequency voltage generated from an ignition coil to the engine ground side. CONSTITUTION:An ignition coil is manufactured in such a manner that ignition- coil component parts such as a case 7 for receiving the coil, in which a primary coil 2 and a secondary coil 4 are received and which is filled with a cast resin 9, cores 13 and 14, a terminal bord 18', etc. are monolithic-molded by a sheathing molding resin 20 consisting of a thermoplastic synthetic resin. An engine can be grounded by electrically connecting a ground terminal 18 to the engine side, and the core 14 and the secondary coil 4 can be shielded electrically. Consequently, voltage charged between the secondary coil 4 and the surface of the case 7 does not reach to the core 14 side, and is discharged to the engine ground side through a conductive substance 16, a connecting terminal 17 and the ground terminal 18 when an ignition plug is discharged.

Title: Submerged pump device for liquefied gas
Inventor: SUZUKI OSAMU
IPC: F04D15/00
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To eliminate imbalanced axial thrust, which is generated when an excessive discharge flow rate low pressure operation is carried out until a pumping pipe is filled up, inside a pump so as to lower a load to a bearing by setting an impeller discharge side ring diameter to be a multiple, which is within a specific range, of an impeller intake side ring diameter. SOLUTION: A dimension of an impeller intake side ring diameter d1 is roughly the same as that of a discharge side ring diameter d2. If d1 equals d2, a pressure distribution generated on the impeller upper face by means of vortex flow is the same as that on the lower face. A generated pressure is affected by a square of the ring diameter (d), so that a pressure distribution with a difference of around 50% is obtained if d2=0.5-12. As a result, similar pressure distributions can be provided both on the upper face and on the lower face of the impeller. In this way, pressures generated on the upper face and on the lower face of the piston 3 are substantially equal to each other and canceled by each other when a discharge pressure in a start of a pump is nearly zero, so that only a load, which substantially equals to the weight of a structure, is applied to a thrust bearing 5.

Abstract: PURPOSE:To use an image forming device by releasing the inhibition of actions in accordance with the state of abnormality in the case that the actions are inhibited because the abnormality occurs in the image forming device. CONSTITUTION:Copying machines A1-A5 are connected to the control device 227 of a service station through a telephone line. In the case the abnormality occurs in the copying machine, maintenance data is transmitted to the device 227. The service station judges the state of the abnormality based on the maintenance data. In the case the state of the abnormality is caused by the life of consumables, quality is not immediately influenced by the abnormality, so that the inhibition of the actions is released until specified time previously set elapses, and when the state of the abnormality does not influence a basic image forming function, a part where the abnormality occurs is separated and the inhibition of the actions is released. Based on the maintenance data, the service station makes a plan for maintenance work and displays it on the control panel of the copying machine, then the inhibition of the actions is displayed when the actions are inhibited, and the release of the inhibition of the actions is displayed when the inhibition is released.
