Title: Aluminum base alloy fed to product forging through casting into product preliminary shape and casting and forging method
Inventor: MASUDA TATSUYA
IPC: C22C21/02
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To reduce the content of Si in the conventional Al alloy for casting and top reconcile the castability and forgeability therein by adding a specified amt. of Be to an Al base alloy having a specified compsn. contg. Si and Mg. SOLUTION: The molten metal of an Al base alloy contg., by weight, 2.0 to 3.3% Si, 0.2 to 0.7% Mg, 0.01 to 0.015% Be, and the balance Al is cast at <=180mm/sec molten metal rate in a spruce into a roughened material having a product predominate shape, and this raw material is forged into a product shape. By the addition of Be, the thickness of Al oxidized coating can be reduced to improve its forgeabiity. As result, not only in the case of casting products having a small-sized and simple shape but also in the case of casting products having a large-sized and complicates shape, surface defects such as flow marls and cold laps are not generated in the casting, and cracks are nor generated at the time of the subsequent forging, by which the product good in quality can be obtd.  Furthermore, the above alloy may be incorporated with prescribed amounts of Ti and B, furthermore, one or more kinds among Cu, Mn, Cr and Zr, one more kinds among Na, Sr, Sb and Ca and P and Fe.

Title: Video image changeover mixing device
Inventor: WATANABE YUICHI
IPC: H04N5/268
Filed: 1990-03-29
Abstract: PURPOSE:To eliminate noise generated up to establishment of synchronization just after the changeover by fixing an output of a synchronizing signal replacement means to a black level for a prescribed period including a period till a black burst signal generating means detects a synchronizing signal from the changeover point of time of a video input signal at the changeover means. CONSTITUTION:At a point of time of changeover of a cross point when a 1st control signal C1 outputted from a control circuit 1 is switched from a signal designating a 1st video input signal to a signal designating a 2nd video input signal, a 3rd control signal C3 predicting the changeover is outputted from the control circuit 1. Then a black burst signal generating circuit 6 receives the 3rd control signal C3 and fixes the black burst data BB to the black level data for a prescribed period (t). Thus, the output of a synchronizing signal replacement circuit 8 is fixed to a black level at the point of time of changeover and production of noise for the period is prevented.

Title: Variable speed driver
Inventor: YAMAMOTO YASUHIRO
IPC: H02P23/22
Filed: 1994-04-21
Abstract: PURPOSE:To obtain a secondary time constant accurately in an early stage by eliminat ing the influence of noise. CONSTITUTION:A current control system obtains voltage commands V1d, V1q for exciting current command I0* and torque current command IT* on a two-phase rotating orthogonal coordinate system and a vector control is effected by determining a slip frequency based on the exciting current command, the torque current command and a secondary time constant tau2 of an induction motor 5. In such variable speed driver, a sequence processing section 21 starts operation while providing a preliminary excitation interval for nullifying the torque current command and generating only the exciting current command. A differential approximation operating section 23 obtains the difference between current and previous values for (n) samples of the exciting voltage V1d of an induction motor during the preliminary excitation interval as a differential approximation sample data string. Each data strmng is fed to a logarithmic operating section thence fed through an accumulating section 28, a matrix operating section 29 and a divider 30 where a linear approximation formula connecting the logarithmic sample data strings is determined by the method of least squares and a secondary time constant tau2 is determined from the reciprocal of the coefficient of linear approximation formula.

Title: Magnetic disk device
Inventor: YONEMITSU SHINOBU
IPC: G11B20/10
Filed: 1988-04-05
Abstract: PURPOSE:To keep data confidential by enciphering plain style data to be recorded to a medium and plain-styling the enciphered data read out of the medium. CONSTITUTION:A read/write head 5 reads the enciphered data from a fixed type rigid medium, and a read/write amplifier circuit 4 amplifies the read enciphered data to be sent via a connecting signal line 9 to a plain styling circuit 3. The plain styling circuit 3 plain-styles the received enciphered data to be sent through a connecting signal line 7 to an interface circuit 1, where the received plain style read data are sent to an external device. Therefore, although the data given and received between the interface circuit 1 and the external device are plain style, the record on the fixed type rigid medium can be the enciphered data. By this method, it is difficult to improperly read the record on the medium, thus keeping the data confidential.

Abstract: PURPOSE: To prevent a cut or a pinhole in resist film to be caused at an indented place, by forming, after the formation of a negative resist pattern, a positive resist pattern of the same size at the same place.  
     CONSTITUTION: Negative resist 5 is coated on semiconductor base 1, which is provided with thick oxide film 2, gate electrode 3 and insulating film 4. By using mask 6, this is exposed and thereby a fixed pattern is formed. Next, positive resist 7 is coated on this. By using positive resist mask 8, which is a reversal of mask 6, this is exposed and thereby a positive resist pattern is formed. The part of insulating film 4 not covered by films 5 and 7 are removed. Next, by removing films 5 and 7, fixed pattern 9 is formed on insulating film 4 on base 1. By this, it is possible to prevent a cut or pinhole in the resist film to be produced at an indented place. At the same time, by using the positive resist, no resist remains within the fixed pattern.

Abstract: PURPOSE:To prevent the occurrence of the unevenness of density in a halftone part in an image which is formed in some first transfer sheets by providing a start delaying means which delays the start timing of a main electrifier with respect to the start timing of a photosensitive body driving means when operation is started. CONSTITUTION:In steady condition the surface of a photosensitive body drum 7 moves at the speed of 72mm per second with respect to the main electrifier device 8. While the main electrifier 8 is connected with a control means 26 through a main electrifier driving means 27. When a printing switch 28 is turned on, the control means 26 sends a motor operation signal as a control signal to a motor driving means 25 to rotate a main motor 24 at first, and after a specified time, the control means sends a main electrifier operation signal to the main electrifier driving means 27 to perform control in the way that the main electrifier 8 is operated. Thus, pin hole appearance, the sticking of a developer containing a carrier to the photosensitive body drum and the occurrence of density nonuniformity due to residual electric potential, etc., are prevented, and the degradation of the photosensitive drum can be suppressed.
