Title: Ball-dropping guiding device with pinwheel for game machine
Inventor: UWAGAWA HACHIROU
IPC: A63F7/02
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To give various changes in the fall of game balls on a game boar surface. SOLUTION: A game ball, upon entering a ball inlet 25a in the upper end of a ball drop guide device with a pinwheel, reaches a pinwheel member 30 disposed in the intermediate part through a path. Then, the game ball is moved to the lower side of the path by the turn of the pinwheel member 30 to be dropped from an outflow port 25c or discharged from an inlet/outlet of the ball. On the other hand, the game ball going to enter the path from the inlet/ outlet of the ball is moved to the lower side of the path by the turn of the pinwheel member 30 to be dropped from the outflow port or pushed back by the pinwheel member 30 to be again discharged from the inlet/outlet of the ball outside the path.  Thus, various changes including a predetermined regularity are given to the move of the game ball dropped onto a game board surface by a ball drop guide device to add an unexpected property to the game, while a visual interest is also provided. The visual interest can be further enhanced by flickering a lamp 43.

IPC: B60G17/015
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To ensure damping ability of a vehicle even when a load on a spring is increased. SOLUTION: A spring mechanism 50 to vary a spring constant is arranged in series to a damper device 40 between a lower arm (a spring lower member) 23 and a car body (a spring upper member), 21.

Title: Electrophotographic sensitive body
Inventor: YOKOYAMA MASAAKI
IPC: G03G5/07
Filed: 1989-11-30
Abstract: PURPOSE:To provide the photosensitive body which is good in safety, sensitivity, resolution and gradation characteristic and has memory performance by forming a carrier transfer layer of the compsn. composed of polysilane and a low- molecular carrier transfer agent consisting of a compd. having a specific ionization potential. CONSTITUTION:The carrier transfer layer 1 is formed of the compsn. consisting of the polysilane and the low-molecular carrier transfer agent having the ionization potential within + or -0.15eV based on the ionization potential of the polysilane. If this layer is irradiated with, for example, UV rays 4, the region irradiated with the energy rays is converted to an insulator 5 and loses the function as the carrier transfer layer 1 in the long run. The unirradiated region functions as an ordinary carrier transfer layer and loses its charges but the negative charges remain in the irradiated region if the entire surface of the electrophotographic sensitive body having the region converted to the insulator in a part is subjected to exposing with visible light after the surface is electrostatically charged with the negative charges. The safety, sensitivity, resolution, and gradation characteristics are improved and the memory performance is provided.

Title: Image forming device
Inventor: SAKAI HIROAKI
IPC: G03G15/16
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which makes a quantity of heat supplied to a transfer material from a fixing means even, and prints an image which is less in irregularity in gloss obtained after fixing. SOLUTION: A motor control means 41 for a driving means which rotates and drives a fixing roller 1 is provided with a transfer-material-carrying adjustment means which is operated at least one and after the second rotation of the fixing means 2 and decreases carrying speed in a fixing process. After the transfer material enters a fixing nip and the fixing roller 1 makes one rotation to apply heat and pressure to toner on the transfer material at the fixing nip while carrying the transfer material at the speed corresponding to the peripheral speed of the fixing roller 1, the transfer-material-carrying adjustment means is turned on to decrease the speed at which the fixing roller 1 is rotated by the driving means 40 and hence the speed at which the transfer material is carried is made slow, thereby increasing a quantity of heat supplied to the transfer material.  Thus, irregularity in the gloss of the front and rear parts of the transfer material is reduced.
