Filed: 1990-03-26
Abstract: PURPOSE:To correctly and speedily measure the width of a flange portion by forming a circular marking line on the upper surface of a base where a container main body is placed to measure the width of said flange portion. CONSTITUTION:A container main body 25 is placed upside down on a base 11. Then, a bottom part 27 of the main body 25 is pressed downwards.

Title: Electronic musical instrument
Inventor: OBATA KATSUHIKO
IPC: G10H3/18
Filed: 1988-03-31
Abstract: PURPOSE:To obtain an abundant musical performance effect by detecting the signal intensity at the time of rise of an input waveform signal and its variation degree and controlling a musical tone, based thereon. CONSTITUTION:An intensity detecting means 201 calculates an average value of the maximum peak value at the time of rise of an input waveform signal which has been derived in advance and the next peak value of the same code as said value, and outputs it as a parameter of the signal intensity. Subsequently, an intensity variation degree detecting means 202 for detecting a signal intensity variation degree at the time of rise of the input waveform signal calculates a ratio of the maximum peak value and the peak value of the next same code, and output is as a parameter of the signal intensity variation degree. Accordingly, when the intensity at the time of rise of the input waveform signal and the variation degree of the intensity are varied independently by a musical performance method, at least two characteristics of a musical tone, for instance, the sound volume and the tone color are varied separately in accordance with the signal intensity and the signal intensity variation degree. In such a way, an abundant musical performance effect is obtained.

Title: Image forming device
Inventor: NAMEKATA SHINICHI
IPC: G03G15/01
Filed: 1989-03-30
Abstract: PURPOSE:To reduce a time until copying a black-and-white image is started after toner is replenished by resetting a Toner-end simultaneously when a front door is closed after a prescribed time during which the front door is opened for exchanging a developer after the Toner-end is displayed passes when a black developer is used, and resetting the Toner-end after concentration is recovered after the door is once opened and closed when a color developer is used. CONSTITUTION:When the black developer is used, the Toner-end is reset simultaneously when the front door is closed after the prescribed time during which the front door is opened after the Toner-end is displayed passes, and when the color developer is used, the Toner-end is reset after the concentration is recovered after a prescribed time passes after the front door is once opened and closed. A toner concentration sensor 1 is arranged at a position at which the developer smoothly flows between a developing roller 3 and an agitating paddle 2. When toner concentration is lowered and an operator finishes a toner replenishing work according to such toner replenishing indication as the Toner-end or a Near-end, the front door is closed and image formation is restarted. Thus the image formation by the black developer can be started soon after toner is replenished.

Title: Washing method for metal copper electrolytically collected from chloride bath
Inventor: IORIZAKI MASAAKI
IPC: C25C1/12
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To lessen waste water contg. harmful copper by washing the metal copper to which cuprous chloride adheres with acidic water while bringing acidic water contg. hydrochloric acid into contact with an iron material. SOLUTION: The copper powder to which the cuprous chloride adheres is housed into a washing device 1. Hot water is supplied from a first supplying pipe 8 and the hydrochloric acid from a second supplying pipe 9 into this washing device 1. The acidic water contg. the hydrochloric acid flows over from a partition wall 5 and is blown out of a spraying pipe 2 disposed under copper powder by the effect of a pump 3. The cuprous chloride dissolves into the acidic water and elutes as CuCl. The CuCl reacts with the iron material housed in the basket 6. The reaction formula is 2CuCl+Fe→2Cu+FeCl2 . The cuprous chloride turns to metal copper and iron chloride soluble in neutral water. The hot water is additionally supplied from the first supplying pipe 8. The washing water flows over from a siphon pipe 7 together with iron chloride and turns to the waste water.  The copper is precipitated as metal copper and is, therefore, not included in the waste water.

Title: Electric control circuit for car
Inventor: ARIGA HISAO
IPC: B60Q1/04
Filed: 1981-05-23
Abstract: PURPOSE:To enable the unlighting and the stopping of engine from the outside of a car, by providing an out-of-car switch on the out-of-car door or other panel while constructing the control circuit with PNP transistor such that the in-the- car switch, ignition switch, etc. can be controlled. CONSTITUTION:Upon closing of the out-of-car switch SW2, a pulse signal is applied through a one shot multi-vibrator 2 to a NPN transistor Tr2. When said pulse signal is high, the base current will flow through the transistor Tr2 to turn on the transistor while to turn off the thyristor SCR. When it is low, the transistor Tr2 is turned off. When SW1 is closed and the transistor Tr2 is conducting, the ON-OFF of the transistors Tr1, Tr2 are synchronized. Consequently the power supply to the load 1 is interrupted. The capacitors C1, C2 are charged through the switches SW2, SW1 and discharged when opening. Consequently the electrical system can be stopped through the out-of-car operation.
