Title: Turbine bucket line
Inventor: KANO YOSHIO
IPC: F01D5/14
Filed: 1988-07-01
Abstract: PURPOSE:To shorten chord length and reduce the weight of a turbine bucket by locating back parts of the maximum thickness parts of each one of plurality of blades circularly arranged at the nearest parts of rear ends of next blades forming flow passages therebetween. CONSTITUTION:A turbine bucket is composed by circularly arranging a plurality of blades 1. The blades are shaped such that the distance DELTAl between a back 7 of blade positioned at the maximum thickness tmax of each blade 1 and a rear end of the next blade forming a flow passage therebetween reaches minimum value under a specified pitch lp. It is therefore possible to shorten chord length without deteriorating blade ability and reduce the weight of the bucket. The same effect is obtained when the maximum thickness position is located in the range between -5 to +5% of the chort length.

Abstract: PURPOSE:To generate a multilevel pulse and to drive a capacitive load, by providing a capacitor between a driver of the first stage and a driver of the next stage and performing the charging/discharging through the capacitor and via a diode in response to the level of an input signal. CONSTITUTION:When a pulse of a ternary level is produced, a driver 1 of the first stage is provided between an earth and a power supply terminal 8 to which a power supply voltage VCC1 is supplied. Then a pulse signal P3 is supplied to an input terminal 3, a terminal 4 is grounded in a high level section of the signal P3. Thus a capacitor 9 is charged with a power supply voltage VCC2 via a diode 11 and at the same time a driver 2 works between the voltage VCC2 and the earth. Then the terminal 4 is connected to the terminal 8 when the signal P3 set at a low level, and the power supply voltage is set at VCC1 +VCC2 to the driver 2. The driver 2 works between the voltage VCC1 +VCC2 and the earth. When the signal P3 is set at a high level again, a path is formed from a load 7 to a diode 12. The output potential is instantly reset to VCC2 by the capacity of the capacitor 9. Thus a signal P1 of a ternary level is produced.

IPC: H01R43/04
Filed: 1989-06-26
Abstract: PURPOSE:To manufacture a product of a high quality in which the press-fit quantity of a terminal and a bend shape are both stably by setting repelling power of a spring of a press-fit tool to a larger value than reaction force at the time of press-fitting, and also, setting a cam so as to be engaged to a bending tool in a process in which the spring is compressed. CONSTITUTION:After press-fitting to a housing 11 of a terminal is completed by a press-fit tool 31, a cam 28 is engaged to a bending tool 32. Also, at the time of bending operation, it does not occur that the press-fit tool 31 descends by compression of a spring 35. Accordingly, it does not occur that press-fitting advances simultaneously. Therefore, the press-fit quantity of a terminal and a bend shape are stable, and a high quality can be maintained. Also, since no immoderate force is applied to a housing 11 and a terminal 12, it does not occur either that they are deformed or the tool side is damaged.

Al wirings 304-306 are connected to source and drain diffusion layers 301-303 through the intermediary of contact holes 307-309, and polycrystalline Si gate electrodes 310 and 311 are formed in a channel region. The junction capacitance between the diffusion layer 302 and the substrate is added to an SC capacitor 102 as a parasitic capacitance 201, and becomes the main cause of impairing transmission chracteristics, but the junction capacitance can be reduced remarkably comparing the case where it is formed as an N-channel form in P-well. Also, the fluctuation of the threshold value of the device due to the VSUB can be reduced by lowering the density.

CONSTITUTION:The impedance Z of a magnetic head circuit 1 increases as the depth length of a magnetic head 5 is reduced due to the wear of the head. As a result, the current and voltage supplied to the primary side of a rotary transformer 4 are varied, and an impedance detecting circuit VIMP goes up in accordance with the change of the depth length of the head 5. Therefore the input voltage V2 of a voltage comparator 8 rise higher than the reference voltage V1, and accordingly the light emitting part of a wear display device 10 extends toward scales t2, t3....
