Title: Recordign current mixing circuit
Inventor: TSUJIMOTO MASATOSHI
IPC: G11B20/00
Filed: 1991-07-08
Abstract: PURPOSE:To reduce the power consumption and also suppress an evil influence such as interference on a video signal due to the flowing of a large current by suppressing a current flowing from an amplifier for high-frequency bias signal recording to an amplifier for sound signal recording and a current flowing from the amplifier for sound signal recording to the amplifier for high-frequency bias signal recording by a parallel resonance circuit and a series resonance circuit and increasing a current flowing to a sound recording head. CONSTITUTION:When an FM sound signal and a PCM sound signal are mixed and a high-frequency bias signal is superposed, the parallel resonance circuit 4 which has a resonance point at the frequency of the high-frequency bias signal is connected to the output side of the amplifier 3 for sound signal recording and the series resonance circuit 7 which has a resonance point at the frequency is connected to the output side of the amplifier 6 for high-frequency bias signal recording; and the outputs of both the circuits 4 and 7 are mixed and sent to the sound recording head 8.

Title: Exhaust gas cleanup device of internal combustion engine
Inventor: ONO HIROSHI
IPC: F02D41/04
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To permit efficient elimination of SOx absorbed by NOx purification means, by controlling so as to vary the air-fuel ratio of the mixture between a lean side and a rich side in detecting degradation of the NOx purification means, and keeping the air-fuel ratio on the rich side when the temperature of the NOx purification means becomes higher than a regeneration temperature. SOLUTION: A NOx purification device 16 is interposed in an exhaust pipe 12 of an engine 1. The device occludes NOx in an exhaust gas lean state where the air-fuel ratio of the mixture is set on a leaner side than the stoichiometric air-fuel ratio and the concentration of oxygen in exhaust gas is relatively high (high NOx ratio), and emits occluded NOx in an exhaust gas rich state where the air-fuel ratio of mixture is set at a rich side and the concentration of oxygen in exhaust gas is relatively low. When degradation of a NOx absorbing agent is detected, the air-fuel ratio of the mixture is varied between the lean side and the rich side at a predetermined period. When the temperature of the NOx purification device 16 becomes higher than a regeneration temperature, the air-fuel ratio is kept on the rich side.

Title: Image forming device
Inventor: KUSUMOTO TOSHIHIKO
IPC: G03G15/01
Filed: 1987-07-07
Abstract: PURPOSE:To precisely position a developing device on an image forming device and to pressurize image carriers with appropriate pressure by installing a conveying means so that the developing device is engaged with the conveying means in a standby position and their engagement is released at an image forming position. CONSTITUTION:A 1st conveying gear 7 is provided so that when the developing device 2A is located at the image forming position, the 1st conveying gear 7 of the conveying means M is not engaged with a rack 2a, whereas when the developing device 2A is at the standby position, said gear 7 is engaged with the rack 2a. Thus, when the developing device 2A is pressurized by a pressurizing means P to move the device 2A to the image forming position from the standby position, the engagement of the 1st conveying gear 7 with the rack 2a is released, therefore the conveying means M and the pressurizing means P never interfere with each other. As a result, the developing device 2A is precisely positioned at the image forming position, and abuts on a photosensitive drum 1 with appropriate pressure.

On the other hand, a tip ball 6 is caulked in a seat having a channel part 5b into which ink 19 is allowed to flow in such a manner that the tip ball 6 is embraced in a freely rotating way while being kept in contact with the seat 14. Further, the ball 6 is pressed by a bar shaft part 18a of a spring 18 inserted into the inner hole of the tip 5 and thereby is brought into contact closely with the inner edge of a ball embracing part 5a. In addition, a ball valve 16 is inserted loosely in the valve chest 13 and a conduit hole 15 is tightly closed by means of the valve 16 when the tip side is turned upward.  When the tip side is reversed, the tight closure is removed to form a gap into which the ink 19 is allowed to flow, in the tip 5. The ink 19 to be used is of a shear-thinning type.
