Title: Blower
Inventor: KUMAGAI YOSHITOSHI
IPC: F04D29/44
Filed: 1980-04-18
Abstract: PURPOSE: To improve a performance of blower suction by a method wherein the suction port is eccentrically positioned at a part having a high suction force at the inner diameter enclosing line in a range of a specified angle from a centre of the multi-vane fan.  
     CONSTITUTION: As shown in the dawing, the suction port 3 is positioned eccentrically from the center of the multi-vane fan 22. That is, the suction port 3 is positioned eccentrically at a place of about 120° in a rotational direction of the main body of the multi-vane fan 22 toward the inner diameter enclosing line of the vane. In this way, it is possible to improve a performance of suction of the blower by a provision of the blower in which the suction port 3 is eccentrically arranged toward the vane inner diameter enclosing line having a high suction force from a center of the mult-vane fan body 22 in a range of specified angle in a rotational direction of the multi-vane fan 22, starting from the nose 23 in the casing.

Title: Initialization of internal memory data of molding machine controller
Inventor: HAYASHI SHIYOUJI
IPC: B29C45/74
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To facilitate the re-input of data necessary at a time of the initialization of data by independently or arbitrarily combining respective memory regions to selectively initialize data. SOLUTION: For example, in such a case that a maker initializes molding condition data and history data used in capacity inspection at a time of delivery from a factory, the number corresponding to each of the molding condition data and the history data is selected by an initializing selection switch 20 or the number corresponding to both data are selected thereby. When a reset button 21 is pushed, both of the molding condition data and the history data are initialized to be capable of being returned to the initial values preset on a program. Since a PID set parameter is stored as a user open machine inherent value even if the molding condition data is initialized, it is unnecessary to initialize the molding condition data as is conventional. When the program is altered to a new one, only user non-open inherent value is selected in the same way to be initialized.

A TRQ3 is conductive at the pulse width tau4 of the signal e2, and since windings W2, W1 of a winding W3 of a transformer T1 are of opposite characteristic, no current flows to the winding W2, the main power TRQ1 and the sub- TRQ2 are cut off and the magnetic energy is stored in the transformer T1. The TRQ3 is cut off after the time tau4 and the energy in the transformer T1 is dissipated via the winding W2 and a diode D5. The TRQ2 is turned on by the signal e1, the base current IB1 of the TRQ1 flows, a high voltage is generated in the winding W2, the TRQ1 is conductive rapidly and a load current Ic flows. When the TRQ3 is turned on again, after the excessive carrier of the TRQ1 is is dissipated via diodes D1-D3, the current Ic of the TRQ1 is cut off.
