Title: Production of expansion formed and extruded planar material
Inventor: MICHISAKA KOUZOU
IPC: C22F1/04
Filed: 1994-12-28
Abstract: PURPOSE: To obtain the extruded planar material broader than the diameter of a die for extrusion by subjecting a planar material to finish expansion forming in a furnace and simultaneously executing a finish expansion forming treatment and age hardening treatment. CONSTITUTION: The planar maternal Y is subjected to finish expansion forming by using a pair of upper and lower forming molds 20, 21 of a size to cover the planar material subjected to expansion forming. The lower forming mold 21 is formed at a size almost corresponding to the planar material Y. The upper forming mold 20 is formed with recessed lines 20a of a size to house leg parts (b) in the positions corresponding to the leg parts of the expansion formed material Y and holds only the flat parts (a) with the lower forming mold 21. The expansion forming material Y is held by the upper and lower forming molds in such a manner and is subjected to finish expansion forming in a high-temp. atmosphere in the furnace 30. At that time, the material is subjected to the age hardening treatment as well. As a result, the capacity at the time of working is decreased.

Title: Power supply device
Inventor: KOMATSU SHUNICHI
IPC: H02J1/00
Filed: 1991-12-12
Abstract: PURPOSE:To provide a power device, in which an uncontrollable state is not generated, when the input voltage of the device is at OFF. CONSTITUTION:When there is capacitive load such as a capacitor at a driving system load terminal, the fall of voltage (No.n+1 output voltage) at the driving system load terminal at a time when the input voltage of a device is at OFF is gentled gradually as shown in an alternate long and short dash in (c), and overlapped to the timing of the fall of control system voltage (No.n output voltage) shown in (b), thus generating an uncontrollable state. Accordingly, the driving system load terminal is short-circuited at a time faster than the timing of the fall of control system voltage, and the fall of voltage at the driving system load terminal is not overlapped to the fall of control system voltage.

Title: Mos type charging and discharging circuit
Inventor: FUJII HIDETAKE
IPC: G11C11/34
Filed: 1987-12-28
Abstract: PURPOSE:To obtain a charging and discharging circuit for large capacity load of satisfactory controllability by setting the thresholds of first and second pchFETs to be almost equal and causing the channel width of the second FET to be an f-fold channel width of the first FET. CONSTITUTION:At first, a sense enable terminal SEN is low and an nchFET Q4 is turned off. Then, a pchFET Q1 is turned on and charged to capacity C. A connecting point SEP of the gate of Q2 and Q3 and the C is high and the Q3 is turned off. When the terminal SEN goes to be high, the Q4 is turned on and the Q2 is turned on by the discharging of the C. After the connecting point SEP is determined by the value of a CR, it goes to be a constant potential. When the impedances of the FET Q2 and Q4 is enough smaller than an R, and the threshold of the Q2 is VTP and the potential of the connecting point SEP is VCC, a bias current IB flowing in the Q4 is used and a charging current IC flowing in the Q3 can be calculated by using channel widths WQ3 and WQ2. Thus, when the dimension ratio of the R, WQ2 and WQ3 is determined, the peak value of the charging current can be accurately set and the rising characteristic of the current can be also controlled accurately by the selection of the C value.

Title: Injector
Inventor: ITO TOSHIHIKO
IPC: F02M61/20
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To put to practical use even electrostrictive actuators of a shorter stroke of needle opening/closing control. SOLUTION: A spill valve 4 frees oil pressure in needle-control oil pressure chamber 411 for generating back pressure on a needle 32 into a low-pressure outlet passage 14. Oil pressure in a spill-valve-control oil pressure chamber 65 for generating back pressure on a valve element 42 of the spill valve 4 is controlled via its own volume that is changed by an expanding or constricting electrostrictive actuator 62. A restriction passage is defined between the spill- valve-control oil pressure chamber 65 and the needle-control oil pressure chamber 411 to lead high pressure in the needle-control oil pressure chamber 411 to the spill-valve-control oil pressure chamber 65, while the needle 32 is closed, so that control oil free from entrained air bubbles and of a high modulus of elasticity can produce back pressure on the valve element 42.  Even a shorter stroke of the electrostrictive actuator 62 can thus change the back pressure on the valve element 42 drastically.

Title: Orientation gradient type functionally gradient material and its manufacturing method
Inventor: WATANABE YOSHIMI
IPC: B22D13/02
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To manufacture an orientation gradient type functionally gradient material in which the volume fraction and orientation of plate-like reinforcement-phase grains in a matrix are gradiently changed simultaneously by using a composite material having plate-like reinforcement-phase grains and applying centrifugal force during melting and solidification and to obtain a composite material whose desired part is reinforced by the desired amount in the desired direction. SOLUTION: Although plate-like reinforcement-phase grains receive moment during the application of centrifugal force and are oriented in such a way that the plate surface normal of the plate-like reinforcement-phase grains becomes parallel to the direction of centrifugal force, the moment differs according to the position of a ring. By using the above phenomenon, a composite material having the plate-like reinforcement-phase grains is used and centrifugal force is applied during melting and solidification. By this method, the orientation gradient type functionally gradient material in which the volume fraction and orientation of the plate-like reinforcement-phase grains in the matrix are gradiently changed simultaneously can be manufactured.
