Title: Oscillation circuit
Inventor: KURISU YASUHIRO
IPC: H03K3/02
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To switch power consumption by a using mode by providing a current limiting circuit for limiting the current of a current path by a processor operated by receiving the output of an oscillation circuit. SOLUTION: A microprocessor 19 controls a current control circuit 18 by an instruction stored in a ROM 20. The output Q20 of the current control circuit 18 can be '0' (low level) at the time of non-oscillation, when oscillation output is insufficient and at the time of the initial state of resetting the microprocessor or the like and be '1' (high level) and '0' (low level) by the instruction when the oscillation is in a stable state. Thus, the power consumption is switched by the using mode and an operation is surely performed with low power consumption. Also, since circuit constitution is simple and the service life of a battery is prolonged, this oscillation circuit capable of further miniaturizing and lightening a portable smallsized electronic device is obtained.

Title: Method of phosphating al-zn alloy plated metallic sheet
Inventor: SHIMIZU TAKESHI
IPC: C23C22/78
Filed: 1991-12-21
Abstract: PURPOSE:To improve the phosphating efficiency of an Al-Zn alloy plated metallic sheet by treating an Al-Zn alloy plated metallic sheet having specified Zn content with an alkali treating soln. with specified pH and thereafter executing phosphating. CONSTITUTION:An Al-Zn alloy plated metallic sheet having 1.0 to 50mass% Zn content is treated by an alkali treating soln. with 9.0 to 13.5pH. In this way, Al on the surface layer of the plated layer is selectively dissolved and Zn on the surface layer is concentrated, by that, its phosphating efficiency improves and its corrosion resistance after coating also improves. Moreover, the Zn content in the plated layer can be reduced to 1.0%. In the case the pH of the alkali treating soln. is less than the lower limit, its dissolving capacity is made insufficient, so that Al can not be dissolved in a short time, and precipitated phosphate crystals are made nonuniform. On the other hand, when it exceedes the upper limit, smut remains on the surface to cause the deterioration in its phosphating efficiency and corrosion resistance after coating.

IPC: G06F13/00
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To allow an NIU to automatically set a configuration parameter needed on operation after connecting a terminal device to a LAN(local network).

IPC: H01L29/78
Filed: 1992-12-28
Abstract: PURPOSE:To relax electric field concentration near a drain and eliminate the device characteristic inhibiting causes by fixing the length of the part of a gate which faces the drain by the specific gate width ratio. CONSTITUTION:The conventional rectangle flat-shape of the gate 2 of a MOSFET with a gate length 0.5mum or shorter is changed and the width of a drain side gate 5 which faces a drain 3 is permitted to be 1.5 or more times wider than the width of a gate 4 which faces a source 1.

Abstract: PROBLEM TO BE SOLVED: To provide a cover device capable of reducing parts in number, of reducing noise due to the movement of a column, and of partitioning the right and left of the column in front and in the rear. SOLUTION: Processing is carried out by means of the triaxial movements of a front and a rear base 2, a column 3, and a main axial head 4 while a main axis 5 is being controlled of its specified three dimensional position with respect to a work to be disposed in front of the column 3.

IPC: C21B7/14
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To restrain the wear of the iron receiving part in an iron tapping spout, to reduce the repairing frequency thereof and to improve net working rate. SOLUTION: When the iron tapping spout 2 is cooled by forming a coolant flowing passage 4 at the outside of the iron tapping spout 2 disposed so as to face an iron tapping hole in the blast furnace 1 and feeding the coolant in this coolant flowing passage 4, the coolant flowing passage 4 corresponding to the iron receiving part 3 in the iron tapping spout 2 is contracted to form a constricted part 5. Cooling capacity is strengthened by making the coolant flowing speed in this portion faster than that in the other portion, and thus the wear of the iron receiving part 3 is restrained and the term to be repaired is extended and the reduction of the repairing frequency and the improvement of net working rate are achieved.
