Abstract: A combination table for both billiards and football table games comprising a billiards table, a supporting seat, and a football table is disclosed. The supporting seat has several supporting legs fixedly attached to the bottom of the billiards table. And the football table can be easily combined with the billiards table via an engaging frame flange inserted into a receiving frame groove. The billiards table is provided with descending tracks communicating corner pockets and side pockets of the billiards table with a ball collecting slot. The football table has slanting plates disposed at the inner side of goals. By means of the descending tracks and the slanting plates, a ball either billiards or football and whether dropped into the ball pocket directly or shot through the goal and then descended onto the pocket, will roll automatically downwards along the sloped descending track and end up finally at the ball collecting slot for retrieval.

Abstract: A device for preventing reverse rotation of a rotor in spinning reels is disclosed. In the device, an operational control shaft is fitted over a connection shaft and biased by a plate spring generating an elastic force. The operational control shaft has two connecting arms extending in different directions. The connecting arms are movably coupled to longitudinal holes of a reverse rotation prevention claw pivoted to a reel body, thereby coupling the operational control shaft to the claw at two coupling points. The turning force of the operational control shaft is thus precisely transmitted to the claw, thereby precisely performing the reverse rotation prevention operation. In this device both the connection shaft and the operational control shaft can smoothly rotate as they are supported by the plate spring.

Abstract: A way of a synthesizing speech by the combination of a Speech coding mode and Formant analysis mode is achieved by segmenting a Formant transition region into portions, according to the linear characteristics of a frequency curve, and storing the Formant information of each portion. Therefrom frequency information of a sound is obtained. Formant information data of a Formant contour to produce speech, is calculated by a linear interpolation method. The frequency and the bandwidth, which are elements of the Formant contour calculated by a linear interpolation method, are sequentially filtered in order to produce a speech signal which is a digital speech signal. The digital speech signal is converted to an analog signal, amplified, and output through a external speaker.
