IPC: A63F7/02
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To easily present an external image or an external voice at low cost and further to effectively utilize it for business. SOLUTION: A game image is displayed on a display part 11 corresponding to the progress of a game and, based on the selection of an image select switch 5, the external image is displayed on the display part 11. Besides, when the display of the external image is selected by the image select switch 5 or no game is played, an image preparing part 25 supplies the external image to the display part 11 but, when the game is played without selecting the display of the external image through the image select switch 5, the game image is supplied to the display part 11. When the progress of the game is moved to any special play state (such as a reach state), however, a CPU 21 controls the image preparing part 25 so as to forcedly switch the supply of the external image to the supply of the game image in spite of this selection.  Thus, the external image is effectively displayed on the display part 11.

Filed: 1986-05-21
Abstract: PURPOSE:To permit easy degassing of packed powder and to improve the quality of the solidified molding of a powder stock by using a container superposed and attached with a net on the inside surface as a container for packing the powder. CONSTITUTION:Two sheets of, for example, 100-mesh nets 7 are stuck to the inside surface of the container 1 and thereafter, a top cap 3 is mounted thereto by welding. After the powder 2 is put into the container 1 from a cylinder 4 to be used as a deaerating pipe, an evacuation device 5 is connected to the pipe and the inside of the container is deaerated to a prescribed vacuum degree by said device. The neck part of the pipe 4 is press-welded and cut by a cutter 6 to hermetically seal the container. The removed air is vented through the upper deaerating pipe 4. Passages are formed between the inside wall of the container and the powder together with the routes between the powder particles so that the air existing between the powder particles near the bottom of the container is also quickly and thoroughly discharged. The evacuated and hermetically sealed container is then subjected to hot hydrostatic pressurization by which the powder 2 is molded to the solidified molding.

IPC: F25B45/00
Filed: 1977-09-30
Abstract: PURPOSE:To automatically supply a liquid refrigerant with a simple constitution by starting the supply of the liquid refrigerant when a liquid refrigerant level sensor detected the lower limit of the level and stopping the supply of the liquid refrigerant when the sensor detected the upper limit of the level. CONSTITUTION:Liquid nitrogen 2 is injected into a cold trap 6 through a siphon 3 as the pressure in a container 1 rises by the heating with a heater 4. When the cold trap 6 is filled with liquid nitrogen 2, a temperature sensor 9 and a meter relay 11 cause a relay circuit corresponding to an upper limit setting indicator 13 to be switched to an H-contact so that the heater 4 and an electromagnetic valve 5 are cut off, thus stopping the supply of liquid nitrogen into the cold trap 6. When an indicating needle 14 reached the level of a lower limit setting indicator 12 as liquid nitrogen evaporates with the lapse of time, the container 1 starts again supplying liquid nitrogen 2 into the cold trap 6.

Title: Electronically controlled fuel injection device for internal combustion engine of vehicle equipped with traction control device
Inventor: KANO KOICHI
IPC: F02D41/04
Filed: 1990-05-09
Abstract: PURPOSE:To prevent over-lean air-fuel ratio so as to enhance driving properties by providing means for correcting the correction factor for the rate of speed reduction in such a manner that the smaller the total number of rotations at deceleration after acceleration, the smaller the rate of speed reduction decided by a speed reduction rate correcting means. CONSTITUTION:If a traction control device works and closes a second throttle valve for the shift to deceleration at the initial period of accelerating operation by means of operation of an accelerator pedal to open a first throttle valve, the total number of rotations is measured by a measuring means from the point when basic fuel injection quantity during acceleration just before the shift to deceleration exceeds a predetermined slice level to that when the basic fuel injection quantity starts to decrease. In such a case, the total number of rotations is small. The rate of speed reduction is therefore decided according to the correction factor for the rate of speed reduction that is corrected by a correcting means in such a manner that the smaller the total number of rotations, the smaller the rate of speed reduction decided by correcting means. As a result, too much speed reduction is prevented and air-fuel ratio becomes proper, thus enhancing driving properties.

In addition, the distances L from the inlet openings of the smoke tubes 1 to the tips of the rod-like members 3 are adequately varied so that the smoke tubes 1 have the natural frequencies different to each other, causing noise due to resonance to be restrained.
