Title: Coin delivery device
Inventor: KAKIZAWA TOSHIO
IPC: G07D9/00
Filed: 1992-12-11
Abstract: PURPOSE:To surely send coins from a delivery part and to considerably accelerate speed for feeding coins out by separating coins by temporarily stopping them, and sending the coins one by one by energizing the edges of coins. CONSTITUTION:The coins are delivered one by one by a delivery belt 30 and stopped by stoppers 31 and 32. Then, a sensor 33 detects the coins and after the lapse of prescribed time, the coins are sent while being separated by driving the stoppers 31 and 32. When the sensor 33 continuously detects the coins, the stoppers 31 and 32 are continuously driven but since the delivering speed of the delivery belt 30 is higher, the coins are sent out after they are temporarily stopped.

Title: Dip coating device
Inventor: SAKAMOTO MASAYUKI
IPC: B05C3/02
Filed: 1988-12-27
Abstract: PURPOSE:To reduce the cost of a photosensitive body and to improve the operability by composing a tank for coating liquid of a large capacity tank for stock solution storage and a small-capacity tank for viscosity adjustment. CONSTITUTION:The stock solution of produced coating liquid is stored in the large-capacity tank 1 for stock solution storage separately from the small- capacity auxiliary tank 5 for viscosity adjustment. In the auxiliary tank 5, a solvent when the viscosity of the coating liquid is large or the stock solution when small is added to adjust the viscosity. At such a time, the capacity of the auxiliary tank 5 is small, so the viscosity is uniformed speedily and even if the stirring speed is made slower than that in the large-capacity tank 11, sufficiently stirred to reduce the production of air bubbles. Further, even when the liquid level is high, the amount of liquid to be disposed decreases. Further, the viscosity need not be adjusted in the tank 11 for stock liquid storage, so the stirring speed can be set slow and the production of air bubbles is suppressed, so the lowest liquid level can be lowered. Consequently, the cost of the photosensitive body can be lowered.
