Title: Electronic stringed instrument
Inventor: IBA AKIO
IPC: G10H1/34
Filed: 1988-09-05
Abstract: PURPOSE:To control rich musical sounds by utilizing respective play inputs in use by controlling the title instrument by a musical sound control means so that the musical sounds generated by a sound source mean corresponding to respective strings differ in characteristics from one another. CONSTITUTION:A microcomputer 40 controls a sound source 70 and an effect addition part 80 according to information set on a musical sound parameter setting panel and play input from a play operation element. The sound source 70 is a polyphonic PCM (pulse code modulation) sound source which performs time-division operation and synthesizes two tone colors together to generate one musical sound. The output of the sound source 70 is supplied to the effect addition part 80, which gives effect to the musical sound. The effect addition part 80 is a polyphonic digital effector which performs time-division operation as well and adds independent effect by musical sound channels. Consequently, play wherein the tone color varies finely like a natural stringed instrument or varies very dynamically at the time of down picking or up picking is enabled.

Title: Double loop type heat exchanger
Inventor: YAMAMOTO ITARU
IPC: F28D15/02
Filed: 1990-08-22
Abstract: PURPOSE:To take out optionally once accumulated heat by a method wherein a heat accumulating part of a primary loop may also act as an evaporator of the secondary loop. CONSTITUTION:In the event that heat is accumulated in a heat accumulating part 15 of a primary loop 12, valves V1 and V2 are closed and valves V3 and V4 are released, and then a heating part 14 filled with the working liquid is heated. The heated working liquid circulates automatically within the loop 12 and the heat is gradually accumulated at a heat accumulating part 15. In the event that the accumulated heat is taken out, valves V3 and V4 are closed and valves V1 and V2 are released, the primary loop side 12 is closed and the secondary loop side 13 is opened. The heat accumulating part 15 is a heating part and then the working liquid heated there evaporates and the liquid is thermally transferred to a condensing part 20. The heat is removed there. The liquid is condensed and again the liquid is returned back to operating liquid of liquid phase and circulates back to the heating part. At this time, a supplying of the working liquid is made stable by a liquid reservoir 21 and at the same time a drying-out of it is prevented. Accordingly, the heat taken out at the condensing part 20 is utilized to change water, for example, into hot water.

Title: Input device
Inventor: MIURA KIYOSHI
IPC: G06F3/0488
Filed: 1994-09-16
Abstract: PURPOSE: To provide the thin and light input device with which a sure input is enabled while such problem as an errorneous input or being left uninputted is eliminated. CONSTITUTION: In the case of an input operation by an operator (omitted in the figure) to a resistant film type touch panel input part 2, the operator can physically sense the pressing of the resistant film type touch panel input part 2 by responding to it as reaction due to the elastic force of an elastic packing 6. Therefore, when that reaction is sensed just weakly, the operator can sense that the pressing is weak so that the input error of no input, even with the intention of input, can be eliminated. Moreover, when the pressure is not stronger than the elastic force of the elastic packing 6, the input is not accepted by the operation of a microswitch 8 of a second switch so that the wrong input can be eliminated.

IPC: G06T5/00
Filed: 1990-08-24
Abstract: PURPOSE:To automatically extract horizontal and vertical boundary information by providing this character/graphic plotter with a means for extracting the vertical/horizontal position information of a segment and a means for extracting boundary position information indicating the inside or outside position of a horizontal or vertical stroke. CONSTITUTION:When the inclination of each segment is less than a previously set threshold, a segment information extracting means 11 finds out a (y) or (x) coordinate value. Then, the means 11 decides that the segment is positioned on the vertical side or on the horizontal side by the number of other segments in the positive direction of the (y) axis or in the negative direction of the (x) axis based upon the coordinates of the intermediate point of the segment and writes the position information. A boundary position information extracting means 12 compares the positional information with the (y) or (x) coordinate value of the segment, extracts the boundary position information indicating the inside or outside position of the horizontal or vertical stroke of the segment and writes the extracted result in a horizontal/vertical boundary information table. Consequently, the horizontal and vertical boundary information can simply be obtained.
