Title: Data encoding method, data encoder, data decoding method and data decoder
Inventor: ISOMURA MASAICHI
IPC: H04N1/417
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To attain the encoding/decoding efficiency of about a same degree of that by an arithmetic coding system and to considerably improve the processing speed. SOLUTION: In the case of receiving a binary bit string, a superior symbol is placed to either of '0' and '1', an inferior symbol is placed to the other, n-sets of consecutive superior symbols are predicted and the result is used for a predicted bit number (prediction setting process: S3). Furthermore, when prediction of a received noted series in a prediction bit number is hit, a signal at '0' or '1' level is outputted as a prediction hit signal and succeeding n-sets of bit series are coded, and when prediction is failed, the other signal at '0' or '1' level is outputted as a prediction failure signal (prediction result output process: S4, S5). When the prediction is failed for a prescribed number of times, a newly reduced prediction bit number less than the (n) is adopted for the prediction bit number, and the similar prediction setting process and the prediction output process are repeated recurrently.

IPC: B22D18/06
Filed: 1993-07-06
Abstract: PURPOSE:To produce an improved precision cast product without needing inter ruption of melting and casting by forming a tapered part enlarged upward from the halfway of the inner wall of a crucible, allowing molten metal to flow down, and solidifying the molten metal by bringing the molten metal into contact with the surface of the tapered part. CONSTITUTION:A base metal 2 is melted by a levitation melting method using a cold crucible 1. The molten metal 7 is sucked and poured into a ceramic shell mold to execute the precision casting. Then, by using the crucible 1 having no bottom, the base metal 2 to be melted is supplied in the form of a bar material having the cross section of a shape corresponding to the inside cross section of the crucible 1 while pushing up the crucible 1 from the lower part. In this case the tapered part 3 enlarged upward from the halfway is formed on the inner wall of the crucible 1. Then the melted metal 7 flows down, and comes into contact with the tapered surface 3 and solidified, by which, while always held in the state of being restrained with the crucible 1, the bar material of the base metal 2 is subjected to precision casting. By this method, this method can easily cope with the production of many kinds in small quantities.

Filed: 1986-07-15
Abstract: PURPOSE:To transmit the state of supervised point correctly by judging whether a selection signal is normal or not, outputting the supervised signal as a fetched supervisory signal only when it is normal and outputting an abnormal signal when not normal. CONSTITUTION:An input selection circuit 4 uses a selection switching command signal CS to bring a selection signal S1 to logical '1' and to bring other selection signals S2-Sn to logical '0', they are outputted and a gate G of a multiplex switching circuit 1 corresponding to the selection signal S1 is turned on to output supervised signals I11-I1n to an input switching circuit 2. Then an input control circuit 3 outputs a switching signal CI to input the selection signals S1-Sm via the input switching circuit 2, thereby confiming only the selection signal S1 to be logical '1' and other selection signals S2-Sm to be logical '0', it is judged that the operation of the input selection circuit 4 is normal, the switching signal CI is switched to fetch the supervised signals I11-S1n from the input switching circuit 2. The fetched supervised signals I11-S1n are subject to processing such as parallel/serial conversion and the result is outputted as a supervisory signal Vs. On the other hand, when it is judged not normal, the fetch of the supervised signal of the group is stopped and an abnormal signal is outputted.

Title: Continuously variable transmission mechanism for automobile which utilizes fluid
Inventor: MURAKAMI MASAHARU
IPC: F16H41/02
Filed: 1987-07-03
Abstract: PURPOSE:To continuously vary the number of revolution and the turning moment by connecting a driving turbine in series with a driven turbine and continuously varying the capacity by forming one side of the walls of the driven turbine into movable type. CONSTITUTION:Since all the fluid discharged from a driving turbine 1 is introduced into a driven turbine 2, if the capacity of the driven turbine 2 increases for the capacity of the driving turbine 1, the revolution of the driven turbine 2 is decelerated, and when the capacity of the driven turbine 2 reduces, the revolution of the driven turbine 2 is accelerated. Since the pressure of the fluid supplied from the driving turbine 1 is transmitted uniformly into the driven turbine 2 by the Pascal's principle, if the capacity of the driven turbine 2 increases for the capacity of the driving turbine 1, the turning moment of the driven turbine increases, while if the capacity of the driven turbine 2 reduces, the turning moment of the driven turbine 2 reduces. Therefore, the same operation to the case of a continuously variable transmission can be obtained by continuously changing the capacity of the driven turbine 2.
