Title: Throttle control device for internal combustion engine
Inventor: KAMADO KOICHI
IPC: F02D9/02
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To improve the control precision and responsiveness of the opening of a throttle valve in an electronic throttle system. SOLUTION: A controlled variable which is converted into a control current to drive a torque motor 19 for setting a throttle value 5 to a specified opening corresponds to the transition of the throttle opening as a control parameter, e.g. and is learned by an ECU 20 and reflected in controlling the next opening of the throttle valve 5. Even if there is dispersion in the controlled variable resulting from product tolerance, aging change or the like, the optimum controlled variable is learned by changing the opening of the throttle valve 5 corresponding to the transition state of a specified control parameter, so that the control precision and responsiveness of the opening of the throttle valve 5 is improved.

Title: Paper sheet accumulating device
Inventor: TAKIZAWA YASUSHI
IPC: B65H33/04
Filed: 1985-11-20
Abstract: PURPOSE:To certainly separate the designated number of paper sheets and the next paper sheets by installing a mixing preventing means at the top edge in the direction of turn of a separator and/or at the top edge part of a vane, in order to prevent the mixing of the designated number of paper and the next paper sheets, when the designated number of paper is separated from the vane. CONSTITUTION:The bent part 30a of a mixing preventing means is installed at the top edge in the direction of turn of a separator 30. Then, the transport top edge of paper sheets contacts a guide member 21, and when the transport rear edge is slipped off from a vane wheel 10, the transport rear edge is prevented from being inserted into between the separator 30 which synchronously turns and the corresponding vane 10a. Said bent part 30a is formed so as to be bent to the vane wheel 10 side so that the gap between each vane wheel 10a of the vane wheel 10 and the separator 30 is reduced to the min. Therefore, the designated number of the paper and the next paper sheets can be separated certainly by forming the bent part 30a, and the error of the number of accumulation in the case when paper money is accumulation-assort in each certain quantity can be prevented.

Title: Control method for conveying transfer paper for color recorder
Inventor: SAKAI YOSHIHIRO
IPC: G03G15/01
Filed: 1988-10-14
Abstract: PURPOSE:To simplify a control operation and to reduce cost by making a distance that a transfer paper is pulled back shorter than a distance that the transfer paper is moved at the time of the image transfer stage for a 1st color and performing the image transfer stage for 2nd and subsequent colors. CONSTITUTION:At the time of the image transfer stage for the 1st color, the distance that the transfer paper 29 is pulled back by the reversely driving the transfer belt 25 is made shorter than the distance that the transfer paper 29 is moved by normally rotating the transfer belt 25, and then the image transfer stage for the 2nd and subsequent colors is made to be performed. Since the speed of a transfer driving motor is not equal to or exceeding that of a photosensitive body 4, the transfer driving motor has only to be controlled to slow up. Then, a low-power output motor is sufficient because high speed rise-up is not accompanied and step-out and the positional deviation of the image can be prevented. Thus, the control operation can be simplified and the cost can be reduced.

Title: High-strength magnetic material and manufacture thereof
Inventor: TANAKA MUNEYUKI
IPC: H01F1/34
Filed: 1988-10-14
Abstract: PURPOSE:To obtain a high-strength magnetic material having a high Q value and density from Ni-Zn ferrite by using at least one or more of Bi2O3, PbO, V2O5 as additives and adding the additives separately before and after calcination. CONSTITUTION:At least one or more of Bi2O3, PbO, and V2O5 are added separately before and after calcination. Since all of the Bi2O3, PbO, and V2O5 are low in melting point as compared with other oxides, they accelerate the sintering of ferrite. When the additives are added even after the calcination, the additives can be distributed widely among crystals and the effect of the sintering can be improved. Moreover, by constructing the crystalline texture of the sintered body in a state where small and large-sized crystals are mixed, formation of cracks in the sintered body becomes complicated and the destroying energy can be dispersed. As a result, the strength of the sintered body can be improved. Therefore, a magnetic material having a sufficiently practical Q value and high strength can be obtained without raising the sintering temperature especially.
