Title: Magnetic tape device and its reading method
Inventor: KAWASAKI HAJIME
IPC: G11B20/18
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To reduce the lack amount of information to a minimum when an error is generated by a method wherein a synchronous character is detected, a set time interval elapses, a synchronous character which is arranged next is then detected, and information which is based on a signal at a time when a data storage region between the two syncrhonous characters is read out is sent out. SOLUTION: When a magnetic tape medium is run, a read signal from a sequential read/write control part 84 is inputted to a data-format control unit 90. The inputted signal is inputted to an IBG detection circuit 94 so as to detect whether the read-out signal refers to a synchronous character or an IBG. In synchronization with a bit which is read out in a burst, a clock in a read operation is generated by a format-control logic circuit 95. When a detecting timer 91 is timed up and when the synchronous character cannot be detected by a synchronous-character detection circuit 93, the format-control logic circuit 95 judges whether the IBG detection circuit 94 detects the IBG or not so as to set the time in which a synchronous character which appears next is detected.

Title: Drive system for multiplex-winding ac motor
Inventor: NISHI YOSHIO
IPC: H02P27/06
Filed: 1985-10-24
Abstract: PURPOSE:To prevent the generation of abnormal currents by inter-winding magnetic coupling without mounting an AC reactor by bringing the voltage of each input winding to the same phase and bringing momentary voltage to the same voltage.

Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To simplify the manufacturing process of a center and improve durable life due to high hardness and low coefficient of friction by coating the tip of a shank with diamond-like-carbon of high hardness, low coefficient of friction, and no adhesion of worn metal powder. SOLUTION: The tip part of a shank 1 made of high speed steel is coated with an intermediate layer 4 made of tungsten, and it is further coated with diamond-like-carbon 5 of high hardness and low coefficient of friction. The intermediate layer 4 improves adhesion strength between the base material of the shank 1 and the diamond-like-carbon. The material is not limited to be tungsten, and any material capable of improving adhesion can be used. The coefficient of friction of diamond-like-carbon against the other metal is under 0.2, and because it has an effect similar to solid lubricant, it decreases wear. This center has high hardness and low coefficient of friction, and adhesion of the metal powder is not generated to prolong the life.

Title: Solar cell, its manufacture, and plating method
Inventor: KAMIYA TAKESHI
IPC: H01L31/04
Filed: 1994-10-03
Abstract: PURPOSE: To provide a solar cell wherein CuInSe2 alloy layer is not exfoliated by heat teatment, and a manufacturing method wherein the installation cost and the installation area cost of a plating equipment can be reduced. CONSTITUTION: A Cr layer 5 and an Mo film 2 are formed on a glass substrate 1, and turned into a body to be plated. Plating solution containing Cu<2+> of 0.01mol, In<3+> of 0.5mol and Se particles of 2.3mol is prepared. In the state that Se particles are precipitated, plating is performed by setting the voltage of the Mo film 2 to be -0.7V, and a Cu layer 6 of 0.2μm in thickness is formed. By stirring the plating solution, the Se particles are made to float and disperse in the solution. The voltage of the Mo film 2 is lowered down to -1.0V, and plating is performed, thereby forming a Cu-In/Se dispersion plating layer 3 on the Cu layer 6. By heat treatment in a gas atmosphere containing Se, the layer 3 is transformed into a CuInSe2 film 4. In this case, the Cu layer 6 acts as an intermediate layer which prevents that Mo comes into contact with Se and reacts. Instead of the Cu layer 6, an In layer or a Cu-In layer can be used.

Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To eliminate a drying process being a pretreating process, and to make a device small in size and low in cost by directly carbonizing dehydrated sludge obtained by dehydrating concentrated sludge. SOLUTION: In the carbonization of the concentrated sludge, the dehydrated sludge obtained by dehydrating the concentrated sludge is carbonized as it is in a state that the drying process is saved. That is, the concentrated sludge about 98% in water content is dehydrated to 70-90%, preferably up to about 80% by a centrifugal separator and the dehydrated sludge is directly carbonized. As the carbonizing temp., the dehydrated sludge is instantaneously heated to the atmosphere of about 50-700 deg.C, more preferably about 600 deg.C. The heating time is about 30-90 min, preferably about 60 min. The drying of water is also carried out together with the carbonization by the carbonization treatment to eliminate the drying process. As a result, the volume and area required for the device is reduced and the device can be made compact.
