Title: Automatic control method of powder filling weights
Inventor: NAKAMURA TEIICHIROU
IPC: B30B11/00
Filed: 1978-06-26
Abstract: PURPOSE: To make automatic controlling of filling weights of powder and achieve higher efficiency of work by detecting the position of an upper punch immediate after pressure compression of powder and adjusting the volume of a cavity.  
     CONSTITUTION: A lower punch 2 is fitted to the die 14 of a specified shape and powder is filled in the cavity 15 formed by the die 14 and lower punch 2. This powder is then compression-molded under approximately constant pressure by an upper punch 23. Here, while the green compact is being held in place by the upper punch 23 and lower punch 2 after the former has compressed the powder, the position of the upper punch 23 is electrically detected 27 and the deviation quantity of said position from the predetermined reference position is electrically measured. By the electric signal corresponding to the results of that measurement, a motor 10 is driven to displace either of the die 14 or lower punch 2, whereby the depth of the cavity 15 is adjusted.

Title: Toner for developing electrostatic charge image
Inventor: KAMITAKI TAKAAKI
IPC: G03G9/08
Filed: 1993-03-12
Abstract: PURPOSE:To obtain a toner forming an image faithful to an original and having satisfactory electrostatic charge characteristics, stable chargeability during use, excellent flowability and cleanability by incorporating a silicone modified compd. having a specified m.p. and imparting a specified wt. average particle diameter. CONSTITUTION:This toner contains vinyl resin or polyester resin as the principal bonding resin and a silicone modified compd. having 15-200 deg.C m.p. and has 3-8mum wt. average particle diameter. The silicone modified compd. acts as an anti-offsetting agent and has excellent transparency in the case where this toner is used as a color toner. Since the silicone modified compd. has no plasticizing effect to the bonding resin, excellent shelf stability is ensured. Since the compd. imparts moderate uniform lubricity to this toner, this toner exhibits satisfactory electrostatic charge characteristics and excellent cleanability on a developing drum especially when the particle diameter of this toner is reduced.

Title: Measurement of concentration of dissolved gas in strong acid electrolytic liquid
Inventor: SATO HIDEYUKI
IPC: G01N27/416
Filed: 1989-03-28
Abstract: PURPOSE:To measure a concentration of dissolved chlorine by keeping a working pole within a range of diffusion limit current density potential with respect to a refer ence pole to measure a current value thereof. CONSTITUTION:A strong acid electrolytic liquid 1 is flows in at one end of a densitometer made up of a frame comprising a vinylchloride resin or the like with a constant flow pump forcibly and discharged at the other end thereof. A working pole 4 and an opposed pole 5 both made of pours carbon are arranged in this tank being separated with a diaphragm 3 made up of an anion exchange film and a current collector 6 made of solid carbon is put tight on the poles 4 and 5 to draw a current as a result of an electrode reaction. Moreover, a reference pole 7 is provided on the outflow side of the electrolytic liquid 1 with respect to the hole 4 and to keep the temperature of the electrolytic liquid 1 constant, a thermistor thermometer 8 is pro vided on the inflow side thereof 1. A densitometer thus obtained is used to examine a relationship between a concentration of bonded chlorine dissolved in the electrolytic liquid and a current flowing through the pole 4 by a constant potential electrolysis of the electrolytic liquid 1. This eliminates an effect completely from other oxidation/ reduction species coexisting in the electrolytic liquid 1 thereby enabling measurement of a desired concentration of dissolved chlorine.

Abstract: PURPOSE:To detect accurately the slip rate of a belt by forming a rotation detection mark part at specific positions on the surfaces of a driving and a driven pulley between which the belt is extended, and detecting the passing of it. CONSTITUTION:Mark detectors 20 and 22 in this example emit measurement light to specific positions of rotation track surfaces of respective rotation detection mark parts 16 and 18 and photodetect reflected light generated when the rotation detection mark parts 16 and 18 pass by the position to output rotation passing detection pulses to FFs 24 and 26. Output signals from the FFs 24 and 26 function as gate pulses of NAND gates 28 and 30 and clock pulses from an oscillator 32 are also supplied to the NAND gates 28 and 30, which are opened when inputting H-level signals from the FFs 24 and 26 to output the clock pulses from the oscillator 32 to counters 34 and 36. Those counters count clock pulses corresponding to the numbers of revolutions of the driving and driven pulleys intermittently on every other turn, and a CPU46 calculates the quantity of a belt slip on the basis of the numbers of revolutions of the driving pulley 12 and driven pulley 14.
