Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To divide an impeller main body into a resin inducer and a sheet metal blade, form the inducer with a three-dimensional curve without using a complex metal mold, easily reduce loss in the vicinity of the inlet port, and realize high intake performance. SOLUTION: An impeller main body 21 is divided into a resin inducer 25 and a sheet metal blade 24. Further, the resin inducer 25 is formed so that shape processing is possible by a side slide metal mold 31 which slides almost radially in the outer peripheral direction of a blade portion 25a. As a result, the inducer is able to be formed having a three-dimensional curve in the vicinity of an inlet port 23a without using a complex metal mold. Further, the outer peripheral portion of the impeller main body 21 is a sheet metal blade 24 so that the outer diameter and blade curvature are able to be freely set regardless of whether the resin inducer 25 is a complex shape.

Filed: 1982-12-10
Abstract: PURPOSE:To generate continuously a symmetric signal in 2/3 frequency with a simple circuit constitution by extracting each of a reference signal and its inverting signal once per three times, and summarizing the extracted outputs. CONSTITUTION:The reference signal f1 generated from an essential frequency dividing circuit B is inputted to the 1st extracting output 1. As a result, a signal f6 extracted once per three times from the signal f1 is outputted from an output terminal (b) of the circuit 1. Then, an inverting signal f1' inverted by an inverter 14 is inputted to the 2nd extracting circuit 7. As a result, a signal f8 extracted once per three times from the inverting signal f1' is outputted from an output terminal (c) of the circuit 7. Then, the signals f6 and f8 are inputted respectively to an adder circuit 13, resulting that a symmetric signal f9 having a frequency of 2/3 to that of the signal f1 is obtained from the circuit 13. A prescribed melody is outputted acoustically from a speaker 17 in the frequency pitch of 2/3 to that of the signal f1 by inputting this signal f9 to a melody generating circuit 16.

The central processing unit 20 finds the direction code sequences as to all the object characters, automatically generates the direction code sequence dictionary with the direction code sequences, and registers the dictionary in a dictionary memory 60. Consequently, the dictionary can be corrected and altered properly corresponding to the object characters.

Title: Scroll type fluid machine
Inventor: IKEGAWA MASATO
IPC: F04C18/02
Filed: 1985-10-02
Abstract: PURPOSE:To prevent a crank type anti-rotation mechanism from being damaged due to thermal expansion of a rotary scroll by attaching a bearing supporting block of the crank type anti-rotation mechanism on a frame of a scroll type compressor in such a manner that the bearing supporting block can move only in the radial direction of a shaft. CONSTITUTION:When a rotary scroll 22 expands due to heat of gas compression and friction of a rotary shaft bearing 10, excessively great shearing stresses are exerted in the radial direction on pin cranks 18 and 18' of a crank type anti-rotation mechanism. However, since bearing supporting blocks 20 and 20' supporting shafts 18a and 18b of the pin cranks 18 and 18' are attached to a frame 5a so that the blocks can move in the radial direction of the shaft, excessively great shearing stresses are prevented from being exerted on the pin cranks 18 and 18'.

Title: Magnetic recording device
Inventor: MURAKAMI YOICHI
IPC: G11B21/10
Filed: 1984-10-17
Abstract: PURPOSE:To highly concentrate tracks without a special servo signal by providing a track servo mechanism employing the difference signal of reproduction outputs of a magnetic head where one track is bisected in the track width direction and a read circuit using a sum signal. CONSTITUTION:When windings 3 and 4 are installed on magnetic cores 1 and 2 are a write current is flowed in coils 3 and 4, magnetizations 6 and 7 in the same direction are caused on a magnetic medium 9. When a track is in the state of off-track by DELTAT at reproduction, in case of the figure, the core 1 is positioned at approximately entire magnitizations 6 and 7 of all track width, whereas some part of the core 2 is positioned in a non-magnetized area. As a result, the output of the coil 3 differs from that of the coil 4, whereby the servo mechanism can be equipped so as to make the output difference zero. The cores 1 and 2 are driven and controlled to adjust the off-track, and therefore sum signals of the coils 3 and 4 can be taken out as reproduction data. Thus, the highly concentrated tracks without using a special servo signal are obtained.

Seal rings 6 are placed inside the annular grooves 5C. As a result, the sealing property of the underground buried pipe 2 is ensured, and it is possible to prevent arrangement error of a duct sleeve with reference to the special part 1.

An RF pulse overlapped slightly corresponding to the four heads is fed to four inputs of a control voltage forming means 21 at recording and a 4-bit digital signal is subject to analog conversion and transmitted by the rotary transformer 8. A switch control means 4 controls each switch of an analog switch 3 based on the transmitted signal voltage. Moreover, in a VTR where two heads for audio FM signal are added, the number of channel of the rotary transformer 8 has only to be increased by one. Since the number of on/off states of the heads is increased, the number of states of the control signal is increased accordingly.
