Title: Motor controller
Inventor: KOBAYASHI HIROKAZU
IPC: H02P25/098
Filed: 1990-04-27
Abstract: PURPOSE:To realize more active control than conventional PI control and to suppress fluctuation on load side with increased response by arranging first and second equivalent disturbance compensating means, respectively, on drive side and load side and additionally providing a block for preventing interference between the second compensating means and other control systems. CONSTITUTION:An equivalent disturbance compensating section 6''' for estimating equivalent disturbance on load side is referred to FCAN and an equivalent disturbance compensating section 6' on drive side is referred to MCAN. Sufficient vibration suppressing effect can not be achieved by simply incorporating a first equivalent disturbance compensating means for feeding an output from the MCAN 6' back to a drive side torque command and a second equivalent disturbance compensating means for feeding back an output from the FCAN 6'''. Consequently, a block 8 for preventing interference of information between MCAN 6' and main speed control system speed feedback is additionally provided. Since the FCAN 6''', passed through a reverse function block 7, contributes to vibration suppressing only on the torsional load side, stability is improved considerably on the load side.

Title: Transistor
Inventor: NAWATA SHIGEAKI
IPC: H01L29/73
Filed: 1982-06-30
Abstract: PURPOSE:To enable to arbitrarily control the decelerating time of switching a transistor having metal base electrode wirings which are contacted with divided base electrode contacting windows by suitably cutting the metal base electrode wirings, thereby selectively isolating the divided base electrode contacting windows in an inoperative state. CONSTITUTION:A transistor has divided base electrode contacting windows 3 ultrafinely divided in a range capable in the manufacturing process, divided emitter region 2, and metal base electrode wirings 4 which connect the windows 3. Part of the metal base electrode wirings 4 is cut as indicated by symbol 4A or 4B in isolated state. Thus, since the parts 4A, 4B no longer contribute to the operation, the period required to draw minority charge stored in the region 1 from the windows 3 becomes long. Various transistors of different decelerating times can be manufactured by selectively isolating part of the windows 3 by cutting the wirings 4. Since the steps of cutting the wirings 4 is near the final step of a wafer process, the middle produce so far is manufactured, and the period to complete the transistor having the desired decelerating time can be extremely short from the time upon the reception of user's order.

Title: Fuel cell power generation plant
Inventor: NAGATA YUJI
IPC: H01M8/04
Filed: 1994-05-27
Abstract: PURPOSE:To extend the life by providing an operating temperature control means for generating a cooling fluid temperature set value in a fuel cell inlet or outlet port by use of two detected values of current value and voltage value, and controlling the actual temperature to the set value. CONSTITUTION:A function generator 8 generates a standard voltage value (e) on the basis of a cell current (a). On the basis of the deviation (b) between this voltage and an actual operating voltage detected value (f), a function generator 9 subtracts a correction value (h) according to the reduction of the cell voltage from a conventional cooling temperature set value (b) to generate a set temperature (i). An opening command (d) is outputted to a regulating valve (7) from a regulator (6) so that the cooling fluid temperature follows the temperature (i). Thus, even to the characteristic reduction with the lapse of time of a fuel cell, the rise of operating temperature of the cell and the acceleration of characteristic reduction of the cell accompanied thereby can be avoided to extend the life.

Title: Radiation shield
Inventor: TSUZUKI KOJI
IPC: G21F5/005
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to shield against both γ rays and neutron beams efficiently at the same time by making a one-layer and pressure-formed structure where a specific weight of a titanium hydride is uniformly scattered in lead. SOLUTION: This shield, where a titanium hydride of 30 to 35 wt.% is uniformly scattered in lead and a one-layer structure is pressure-formed, is provided with crushing strength of 100 kg/cm<2> or higher. On this occasion, the lead and the titanium hydride are used to shield against γ rays and a neutron beam respectively. The one-layer structure can efficiently shield against both 7 rays and neutrons at the same time by setting the weight of the titanium hydride to the lead at 30 to 50%. In this range, the ratio of a titanium hydride to lead can also be changed due to the quality of radioactive wastes. Since the volume of a titanium hydride whose specific gravity is low increases in this case, it is difficult to form the shield through a uniform mixture in a molten condition.  For this reason, lead and a titanium hydride are evenly scattered by a powdered metal technique to form a one layer structure by pressure.
