Filed: 1987-07-30
Abstract: PURPOSE: To form a string or fundamental tones in consideration of information of a melody line by providing a self-line reference type fundamental tone estimation means, which refers to the just preceding fundamental tone to estimate the current fundamental tone, and a melody line reference type fundamental tone estimation means which refers to the melody line to estimate the current fundamental tone.

At the time of determining the fundamental tone, not only the just preceding fundamental tone as self-line information but also information of a melody line as another line is taken into consideration. That is, not only the just preceding fundamental tone but also information of the melody line are elements to determine the current fundamental tone. Consequently, a fundamental tone string of an accompaniment line is obtained which has a level, which cannot be achieved by a conventional technique, and is plentifully musical and is consistent with the melody line.

Title: Air conditioner
Inventor: TAGUCHI AKIRA
IPC: F24F5/00
Filed: 1988-07-28
Abstract: PURPOSE:To enable execution of efficient heat exchange and to improve appearance by reducing the opening of a strip footing part by a method wherein a ventilating circuit on the discharge side of an outdoor machine contained under a floor is coupled to the strip footing part having an air shield plate and a ventilating port with a blower. CONSTITUTION:Through operation of an outdoor machine 1, a blower 1C is run and draft sucked through a ventilating port 5 forming the suction side is guided to a ventilating circuit 1a on the suction side of the outdoor machine 1. The draft causes a heat exchanger in the outdoor machine to perform heat exchange, and thereafter is discharged through a ventilating circuit 1b on the discharge side and after it flows through a discharge draft chamber A, it is guided to a ventilating port 3 on the exhaust side. In which case, an air shield plate 2 partitioning the ventilating circuit 1a on the suction side form the ventilating circuit 1b on the discharge side is mounted to the outer shell of the outdoor machine 1 and a strip footing 4 having a ventilating port 3 on the exhaust side is coupled thereto to form a closed discharge draft chamber. Thereby, heat-exchanged draft is not returned to a ventilating circuit on the suction side but with a blower 3a run, the draft is forcibly exhausted through the ventilating port 3 to the outside of a building. The outdoor machine and the blower perform efficient heat exchange as an air conditioner.

Title: Engine restarting improver for automobile
Inventor: MATSUNAGA MORISHIRO
IPC: B60K13/00
Filed: 1984-09-10
Abstract: PURPOSE:To obviate a worsening of restarting due to evaporating fuel, by making the evaporating fuel staying in a suction system draw in a negative pressure tank of a brake booster mechanism by suction, when an engine is restarted in time of high temperature. CONSTITUTION:When an engine is stopped in time of high temperature in a suction system, a large quantity of evaporating fuel stays in each line part A of a suction pipe 4 and a carburetor 3. Under this condition, if the engine is restarted, a switch 9 and a temperature sensor 8 are conducted with each other whereby a solenoid valve 61 temporarily opens. In consequence, since a negative pressure tank 53 of a brake booster mechanism 5 and the suction pipe 4 are interconnected through a passage 6, the evaporating fuel is absorbed inside the negative pressure tank 53 owing to a pressure differential whereby the staying quantity is reducible. On the other hand, the evaporating fuel absorbed inside the negative pressure tank 53 flows back to the inside of the suction pipe 4 and is made into combustion with a check valve 52 opened at the point that the engine is started and the suction pipe comes to negative pressure.

Abstract: PURPOSE:To prevent the accompanying rise of a ground improving agent by a method in which a casing is penetrated into the ground, a long bar-like member is inserted into the casing to open the tip of the casing, and a ground improving agent in the casing is pushed out into the ground. CONSTITUTION:The motor 4 of a rotary driver is operated to penetrate a casing 8 along a leader mast 2 into the ground while being turned, and a ground improving agent 13, e.g., sand is packed into the casing 8. A vertically movable motor is driven to pull up the rotary driver and the casing 8, whereupon the cover 10 of the casing 8 opens and the improving agent 13 is discharged to the outside. At the same time, a long bar-like member 11 goes into the casing 8 to press downwards the upper end of the improving agent 13 by its tip to push out the improving agent 13. The improving agent 13 so discharged in order is left in a columnar form in the pit to form a drain.
