Title: Reactor iron core minimal in saturation iron loss
Inventor: NAMIKAWA MISAO
IPC: C22C38/00
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a reactor iron core minimal in saturation iron loss even if saturation excitation is performed at a sharp pulse by using a high silicon steel sheet containing Si in a weight percentage in a specific range. SOLUTION: As seen in the figure which shows the iron loss characteristic with respect to the amount of Si, measured by using a nonoriented silicon steel sheet of 0.1mm sheet thickness, at the time when saturation excitation is performed under the conditions of rectangular wave, 50Hz cycle frequency, and 4000A/m excitation magnetic field, it becomes evident that saturation iron loss can be minimized by using a high silicon steel sheet of 4-7wt.% Si content even if saturation excitation is done at a sharp pulse. Therefore, in this method, the reactor iron core minimal in saturation iron loss is produced by using an inexpensive high silicon steel sheet of 4-7wt.% Si content, having relatively high saturation magnetic flux density.

Filed: 1991-02-04
Abstract: PURPOSE: To obtain continuously the subject compound useful as oxidizing agents with a higher state of purity and yield in a short reaction time without danger, by metering a sulfuric acid solution of an imidocarboxylic acid and an aqueous solution of hydrogen peroxide into a static mixer and treating the product with water.  
     CONSTITUTION: A solution of an imidocarboxylic acid of formula I (A is 2-4C alkylene, phenylene, naphthylene, etc.; X is 1-19C alkylene, preferably 2-11C alkylene or arylene, preferably phenylene) in sulfuric acid or methanesulfonic acid and an aqueous solution of hydrogen peroxide are metered into a static mixer. The resultant product is treated with water to precipitate an imidoperoxycarboxylic acid of formula II, which is then isolated. Since the residence time of the compound of formula I and the aqueous solution of hydrogen peroxide in the static mixer is relatively short as 0-10 seconds, and thus no external cooling is necessary, the compound of formula I in concentrated sulfuric acid is mixed in a continuous process without a risk with a concentrated hydrogen peroxide solution and can be brought to reaction.

Title: Signal transmitter
Inventor: MATSUKA TETSUYUKI
IPC: H04L1/00
Filed: 1988-01-25
Abstract: PURPOSE:To reduce the transmission time by increasing number of times of reply transmission when the frequency of occurrence of retransmission is high and decreasing number of times of reply transmission when the frequency of occurrence of retransmission is low. CONSTITUTION:The reply request number of times between the succeeding 5-frame synchronizing signal periods is decided by the frequency of occurrence of reproduction caused among 5-frame synchronizing signal periods by a reply request discrimination section 104. That is, if the retransmission occurrence frequency P is low, the reply request number of times is less and when the retransmission occurrence frequency P is high, the reply request number of times is high. Thus, it is possible to reduce the reply frame transmission number of times in the line with excellent line quality by controlling the reply frame transmission number of times depending on the frequency of occurrence of reproduction to reduce the transmission time.

Abstract: PURPOSE:To reduce the number of signal lines for transmitting a control signal, to reduce a cost, and also to improve a reliability of a device by varying a pulse width of a strobe signal outputted to an I/O by an electronic computer body side. CONSTITUTION:An interface controlling circuit 23 of an electronic computer body 21 side has a means for varying a time (pulse width) extending from reception of an acknowledge signal of an I/O24 to an output of a strobe signal in accordance with varous operation modes such as a data transfer, etc. to the I/O24. Also, an interface controlling circuit 27 of the I/O24 side detects a time extending from an output of the acknowledge signal to a stop of the strobe signal, and has a means for recognizing the operation mode by a length of this time. According to such a constitution, a control signal to be sent and received between the body 21 and the I/O24 becomes only two kinds of the acknowledge signal and the strobe signal, and the number of control signal lines between the body 21 and the I/O24 can be decreased. Accordingly, a cost is reduced, and a reliability of a device can be improved.
