Abstract: PROBLEM TO BE SOLVED: To prevent the generation of shock at the time of changing a shift lever from P, N ranges to D, R ranges in a foot brake state and at the time of upshift or downshift by interposing an idling means for making a stator idle, between a one-way clutch and a case. SOLUTION: A torque converter 10 is composed of an idling means 11, a casing 14, an input shaft 31, a pump impeller 33, a turbine runner 34, an output shaft 35, a stator 36, a one-way clutch 37, and the like. Until the lapse of specified time T-T after shift or until a rotating speed ratio (e) becomes a specified rotating speed ratio or less or until the rotating speed (r) of the output shaft 35 becomes specified rotating speed or less after a shift, the idling means 11 is operated to make the stator 36 idle. Torque generated to the turbine runner 34 and output shaft 35 is therefore lowered so as to relax shock generated at the time of a shift. The uncomfortable feeling of an occupant is therefore reduced, and the damage of the output shaft or the like is prevented.

Title: Product supplying device on product transfer conveyor
Inventor: IWATA YASUO
IPC: B65G47/78
Filed: 1986-12-25
Abstract: PURPOSE:To reduce the dimension of a conveyor and increase the feed quantity by detecting the gap between products at two positions on the upstream side and downstream side of a conveyor and once stopping a product in the vicinity of a gap detector on the downstream side when the gap is detected and then feeding products into the downstream side space. CONSTITUTION:When detector 1, 2, and 13 do not detect the gaps S1 nor S2 between products, supply operation is not performed, since products (a) are transported continuously on conveyors c3, c4, and c5. When the detectors 13, 1, and 2 detect the gap, a solenoid 5 operates to project a stopper 3, which is set at the operation position, and cuts off the product flow. During this time, a supplying pusher 10 operates to supply a supplied article (a') on the lowermost stage which is supplied from a supplying hopper 4 onto the conveyor (c3) from supply port 8. After a certain time, the stopper 3 is moved upwardly, and the transport of the products (a') is restarted. With such constitution, the dimension of the conveyor is reduced, and the feed quantity in the product flow can be increased without deteriorating quality.

Title: Snubber circuit for semiconductor switch element
Inventor: SAOTOME HIDEO
IPC: H03K17/16
Filed: 1986-12-29
Abstract: PURPOSE:To decrease the turn-on loss by connecting a saturable reactor to a discharge line of a capacitor being a component of a snubber circuit so as to slow down the leading of a discharge current when a semiconductor switch element is turned on. CONSTITUTION:A saturable reactor 5 is connected in series with a resistor 4 of the snubber circuit. The saturable reactor is not subjected to magnetic saturation at the leading of a discharge current (i) of the capacitor 3 but acts like an inductance and its magnetism is saturated after a terminal voltage Vak of a thyristor 1 is sufficiently decreased. Thus, when the thyristor 1 is turned on, the leading of the discharge current of the capacitor 3 slows down and the switching loss is decreased. While the reactor 5 is saturated, the discharge current of the capacitor 3 flows with the same timewise gradient as that of a conventional circuit and the thyristor 1 is protected at the turn-off by the same operation as that of a conventional snubber circuit after the discharge of the capacitor 3 is finished.

Abstract: PROBLEM TO BE SOLVED: To provide environment wherein timing analysis and logic composition can accurately and easily be performed by easily inputting the timing specifications of the circuit at a function description stage without any omission. SOLUTION: An inter-facility connection information storage part 11 is a file containing connection information between facilities by the layers of the circuit and a facility indication part 12 takes registers in a specified module out of the inter-facility connection information storage part 11 and displays them on a screen so that a register whose connection relation should be found will be indicated. An inter-front-and-rear-stage-facility display part 13 takes the connection information of the indicated register out of the inter-facility connection information storage part 11 and displays it on the screen. An inter- facility timing specification input part 14 allows the number of cycles and whether or not there is a corresponding false path to be inputted on the screen.  Then a timing specification description generation part 15 converts information inputted on the screen to a VHDL description and inserts it into a function description stored in a specification description storage part 16.
