Abstract: PURPOSE: To smoothly change the hands and fingers from a current chord playing state to a next chord playing state. CONSTITUTION: A musical performance information supply means supplies performance information showing the current key depression state of a keyboard 11. A chord information supply means supplies chord information. A chord determining means determines a key depression state close to the current key depression state corresponding to the performance information as the key depression state of the chord corresponding to the chord information and outputs chord information showing the determined key depression state. A key depression indicating means indicates key depression positions on the keyboard 11 on the basis of the chord information outputted from the chord determining means.  Further, when the chord information supply means automatically supplies the chord information, the chord determining means determines the key depression state close to the current key depression state corresponding to 1st chord information as the key depression state of the chord corresponding to 2nd chord information supplied right after the 1st chord information and outputs chord information indicating the determined key depression state. Further, the key depression indicating means retrieves a key which should be pressed and can not be omitted and a key which needs not be pressed and can be omitted from the chord information supplied from the chord information supply means and indicates the retrieved key which can not be omitted and the key which can be omitted in different forms.

Abstract: PURPOSE:To certainly remove polyvinyl alcohol(PVA) from PVA-contg. liquid waste at a low cost, by adding one or more of water-soluble mineral salts, phosphates and carbonates, and silica or a silicate to the PVA-contg. liquid waste, and then agitating the liquid waste to salt out PVA. CONSTITUTION:PVA-contg. liquid waste 1 is received in a reactor tank 2, a water-soluble salt such as sodium sulfate 3 is added to it, and the liquid waste is sufficiently agitated by an agitator 4. Thereafter, silica 5 is added to it and sufficiently agitated, so that PVA having relatively large molecular weight in the liquid waste is precipitated. The reaction liquid is let flow through a screen 7 of 20-30 meshes using a pump 6 to filter the precipitate 8, and the resulting filtrate 9 is obtained in a reservoir 10. Then, the filtrate 9 is introduced into a catalytic oxidizing tank 11 using a pump 6', while air obtained from a blower 15 is supplied to the tank 11 through its lower part. As a result, PVA having relatively small molecular weight contained in the filtrate 9 is oxidized biologically.

Title: Incinerating device
Inventor: TAKAHATA YOSHIAKI
IPC: F23G5/50
Filed: 1995-03-27
Abstract: PURPOSE: To detect burnout position correctly by a method wherein the burnout position of waste, judged by the picture data of a pickup means, is corrected to the downstream side by a burnout position judging means when the detecting temperature of a temperature detecting means has exceeded a set temperature. CONSTITUTION: A temperature near a place at the downstream side of a transfer passage TP is detected by a temperature detecting means 30. When the detecting temperature has exceeded a set temperature, a burnout position, judged by a burnout position judging means through the picture data of a pickup means IM, is corrected to downstream side. According to this method, the thickness of waste becomes thick or the thickness of waste becomes uneven in the widthwise direction of the transfer passage TP in spite of the existence of the actual burnout position at the downstream side.  Even when the burnout position exists at upstream side by the judgement through only the picture data of the pickup means IM, the actual burnout position exists at the downstream side and a temperature near the place at the downstream side of the transfer passage becomes high whereby the burnout position, judged by the picture data of the pickup means, can be corrected to the downstream side.
