Abstract: PURPOSE:To reduce cutting force and increase shape accuracy, by reducing the feeding speed of a tool to machine a work piece in accordance with the increase ratio of the length of the cutting arc of tool decided from the radius of an end mill and the curvature of an involute curve. CONSTITUTION:When the outer and inner wall faces of a scroll wrap 1 are processed by an end mill tool 2 to make an involute curve, after the locus of tool has been calculated from the data regarding to the preparation of tool locus, in which an appropriate distribution of the tool-feeding speed is automatically input by a tape or the like, by use of a NC device, an equivalent radius of curvature of the tool locus for the time when the outer and inner wall faces of the scroll wrap are processed is calculated. The previously input tool-feeding speed is made 100% and the tool-feeding speed is gradually made 100% as the equivalent radius of curvature increases. Ans also, the feeding speed is appropriately distributed in accordance with the feeding speed operation function gradually delaying the speed as the equivalent radius of curvature increases to numerically control the driving motor for the processing table.

Abstract: PURPOSE:To always maintain the specified anion quantity with respect to an inside volume of a chamber (vehicle) by providing an operation control section which controls the air flow rate by an electric fan, an anion generating section, and an anion quantity control section which controls the quantity of the anions to be generated. CONSTITUTION:An automatic or manual operation is discriminated and, for example, the manual operation is selected if the high-, middle- and low-speed continuous operations are selected by a switch 14. The on time and off time of pulses by an anion regulating section 11 are so controlled by the anion quantity control section 20 as to be made the same in the case of the middle-speed operation. A high voltage is, therefore, impressed to the anion generating section 4 in such a manner that the impression time and the non-impression time are the same. The quantity of the anions to be added at this time is so set as to be optimized. The pulse on time is so controlled as to be made shorter than the off time in the case of the high-speed operation and the impression quantity of the anions increased by an increase in the air flow rate is decreased. The control reverse from the high-speed operation is executed in the case of the low-speed operation and the impression quantity of the anions is increased. The quantity of the anions to be impressed is thus so maintained as not to exceed the optimum quantity in spite of a change in the air flow rate.

Title: Encoding transmitter
Inventor: ISEDA HIDEHIRA
IPC: H04J3/16
Filed: 1988-12-06
Abstract: PURPOSE:To attain efficient transmission with an encoded output having the least encoded bit rate by applying the transmission according to the optimum encoded bit rate in a form that the characteristic of human audible sense, of a voice signal and of an encoder is taken into account. CONSTITUTION:An evaluation device 5 extracts a decoder 2-j having the least encoded bit rate among decoders whose S/N is within the permissible range in comparison with the S/N of a reference decoder 4 in reference to the S/N, for example. Moreover, when the S/N of outputs from the decoders 2-1,2-2,...,2-N' does not satisfy the permissible criterion of the S/N of the output of the reference decoder 4, the reference decoder 4 itself is extracted. Then a selection changeover section 6 inputs an encoded output of an extracted decoder to a multiplex section 7 and a multiplex section 7 sends the received encoded signal and the selected encoded bit rate with multiplexing. Thus, the encoded output with the least encoded bit rate is used for the transmission efficiently.
