Title: Steel hardening using liquid cooling medium
Inventor: MAINERUTO MAIERU
IPC: C21D1/02
Filed: 1990-08-17
Abstract: PURPOSE: To easily apply total hardening to a bar-shaped product of relatively large diameter by feeding a rolled product made of steel to a cooling region having a cooling medium immediately after a rolling process and exposing the product to a high flow rate medium.  
     CONSTITUTION: A bar-shaped rolled product, composed of heat treated alloy or nonalloy steel, is supplied, immediately after a rolling process, to a cooling region having a cooling medium (wafer, oil, etc.), exposed to the medium of flow rate as high as to produce ≥50,000W/m 2 /K heat transfer coefficient, and cooled until the average temp. of the cross sectional area of the rolled material reaches a temp. not higher than the MS-temp. By this procedure, in the product taken out of the cooling region, the austenite in the central part is transformed into a structure (bainite) of intermediate stage by soaking over the whole cross section, and simultaneously, by the reelevation of temp. up to the MS-temp. at the highest in the edge structure of martensite, most of the applied thermal stress and transformation stress can be removed. By this method, total hardening can be applied to the bar-shaped rolled product of relatively large diameter of ≤70mm while remarkably reducing energy and costs.

Abstract: PURPOSE:To obtain a satisfactory video output and to attain the smooth tape driving by applying the load which increases and decreases in response to the revolving speed of a reel turntable to said turntable which takes up a tape and therefore reducing the changing range of tape tension due to a change of the tape take-up diameter of a reel. CONSTITUTION:A reel turntable 12 is supported rotably by a substrate 14 via a shaft 13, and the load is transmitted to the turntable 12 from a load source 11 via a gear 21. This load varies, i.e., increases and decreases when the revolving speed of the turntable 2 is high and low, respectively. Therefore the torque acting on the tape is reduced when the tape take-up diameter is small with a large number of revolutions of the turntable 12. While the reduction of the torque acting on the tape is avoided when the tape take-up diameter is large with a small number of revolutions of the turntable 12, respectively. Thus the smooth tape driving operation is ensured.

Title: Electromagnetic induction type rotary encoder
Inventor: SAWAI TSUTOMU
IPC: G01D5/245
Filed: 1989-08-22
Abstract: PURPOSE:To obtain an encoder the lifetime of which is prolonged by a non- contact-type construction and which is suitable for a battery drive, by generating a pulse signal by a coil which is disposed oppositely to a ring-shaped magnet magnetized at prescribed intervals. CONSTITUTION:A ring-shaped magnet plate 18 provided with a magnetized part 18a and a non-magnetized part 18b alternately is fitted to a round rotary plate 17 provided at the lower part of an operation shaft 16, while a coil 20 is provided on an insulating base 19 at a position opposite to the magnet plate. When the operation shaft 16 is rotated for operation, a pulse signal is outputted to a terminal part 21 by an electromotive force caused by electromagnetic induction when a magnetic flux generated by the magnetized part 18a passes through the coil 20. Since a non-contact-type construction is adopted in this way, no deterioration occurs and a lifetime becomes semipermanent, compared with conventional contact-type or photo-semiconductor-type devices. Since the electromotive force is generated by using the coil 20, besides, an external power source is dispensed with, power consumption is regarded as zero and so a device thus constructed is suitable for a battery drive.

IPC: H01F1/22
Filed: 1986-09-17
Abstract: PURPOSE:To enable forming various complex shapes by a resin molding and to improve the electromagnetic characteristics by molding an amorphous alloy power using a resin as the binder. CONSTITUTION:Using an Fe-Co-Si-B system is used as amorphous alloy powder, the molten alloy is dropped on a roll of bad wettability and is further caused to impinge on a cooled metal roll to become amorphous. Then, the resin acting as the binder to be used for molding the amorphous alloy powder obtained in this way is desirable to be as less as possible in amount and have a strong binding force, and also considering the water resistance and environmental resistance, an epoxy resin is preferred. Further, if the diameter of the amorphous alloy powder is small, the viscosity before the molding becomes large and the magnetic characteristics will degrade, and if the diameter is large, the gaps become many and the packing rate becomes small, so that diameter of the alloy powder is preferably not smaller than 20mum and not greater than 200mum. With this, complex shapes can be made by an inexpensive process, and it is also possible to provide excellent magnetic characteristics.

Abstract: PURPOSE:To make consideration on the baseband polarity of an FM transmission line unnecessary, by providing circuits of differential logical conversion and differential logical inversed conversion, at a transmission side and a reception side, and applying the differential logical conversion/inversed conversion only on the binary data signal of a column corresponding to one bit of the highest-order. CONSTITUTION:A signal at a first column(corresponds to high-order one bit) out of the binary data signals in two columns inputted from a binary NRZ data signal input terminal 1 is differential logical-converted through an exclusive OR circuit 3, and is added on a one-bit delay circuit 4. The signal at a second column(corresponds to a low-order one bit) inputted to an input terminal 2 is added on a one-bit delay circuit 5. The outputs of the delay circuits 4 and 5 are converted to the baseband signals of four values at a binary/four value conversion circuit 6, and are transmitted on the FM transmission line 7, and are changed again to binary data signals at a four value/binary conversion circuit 8, and the signal at the first column corresponding to the high-order one bit is differential logical inversely converted. In this way, it is possible to obtain an original binary NRZ data signal correctly even when the polarity of a four value data signal is inverted, or non-inverted.

Title: Method for shaping waveform of digital signal
Inventor: ICHIE TAKAMICHI
IPC: H04L7/027
Filed: 1985-09-30
Abstract: PURPOSE:To exclude the phase distortion of a signal without causing any under- run state by detecting the binary state of a signal to store it sequentially and outputting a signal of a prescribed level sequentially corresponding to the stored binary state after prescribed time elapses from the start point of time of storage. CONSTITUTION:A clock extraction circuit 17a, in detecting the 1st state change of a reception signal S1 (point of time t1), counts a clock signal CP1 just after the detection and produces a sampling clock signal S2 when the 5th signal is generated (point of time t2). Then the circuit 17a, in detecting the CP1 signal just after the generation of the 8th CP1 signal or the CP1 signal just after the signal S1 is changed again (point of time t3), regards it as the 1st CP1 signal again and stops the signal S2 as soon as the CP1 signal is generated (point of time t4). The signal S2 is given to a memory 18a, which stores the binary state of the signal S1 in the timing when the signal S2 rises sequentially and gives the signal S3 to a transmission clock generating circuit 19a. The circuit 19a gives the transmission clock signal CP2 corresponding accurately to the communication speed to the memory 18a after a prescribed period T elapses. Thus, the signal S1 is waveform-shaped into a signal S4 having the same phase as the original transmission signal.

Abstract: PURPOSE:To always obtain a stable printing quality even when destaticization is not executed at all or not executed enough and even when a printing interval is sufficiently given by executing a preliminary electrification for one rotation or above of a photosensitive drum, when the printing interval is given for a prescribed time or above. CONSTITUTION:When a motor driver of a driving part 23 becomes OFF, a CPU 20 starts a timer T, checks a time interval to the next start signal, sets a flag FL when the time elapses exceeding a prescribed time, and when a printing start signal arrives, if the flag FL is set, a photosensitive drum 10 is brought to preliminary electrification for one rotation or above before printing is started. Accordingly, immediately before a printing operation, the photosensitive drum 10 always has a high potential of some extent, the photosensitive drum 10 reaches a prescribed saturated potential by preliminary electrification by the printing operation, and the fogging of printing, etc., can be prevented. In such a manner, even when destaticization is not executed or not executed enough, printing can be executed with a stable printing quality irrespective of a printing interval.
