Title: Picture quality adjustment circuit
Inventor: KITAMURA MASAHIRO
IPC: H04N5/205
Filed: 1988-11-28
Abstract: PURPOSE:To attain picture quality adjustment without emphasizing a noise component of an input video signal by using a slicer circuit so as to eliminate noise component from an output of an HPF. CONSTITUTION:A high frequency component of a video signal inputted to an input terminal 1 passes through an HPF 2 and the output of the HPF 2 is sliced by a slicer circuit 3. Since the level of noise component is in general smaller than an output level of the HPF 2 from the video signal, when the slice level of the circuit 3 is set properly, a signal being the result of eliminating noise component from the output of the HPF 2 is obtained. The gain and phase of the output of the circuit 3 are controlled by a gain/phase control circuit 4 and the result is mixed with an input video signal by a mixer circuit 5 and the mixed signal is outputted at an output terminal 6. When the phase of the output of the circuit 4 is in phase with the input video signal, since the high frequency component is emphasized, a video with sharp picture quality is outputted at the output terminal 6. When the phase of the output of the circuit 4 is opposite to the phase of the input video signal, since the high frequency component is attenuated, soft picture quality is obtained.

Title: Spring cam mechanism
Inventor: KASASHIMA YUKINORI
IPC: F16H21/36
Filed: 1988-11-29
Abstract: PURPOSE:To make a spring cam mechanism simple and small-sized and to simultaneously obtain both functions as spring performance and cam mechanism by applying spring property to a movable member to be engaged and controlling the position of the movable member by a cam mechanism. CONSTITUTION:When a transport member 3a is slid in the direction of an arrow F and a conical shape 5c is horizontally moved on a rising guide portion, a cam mechanism K engaged with a hole 5a1 is strongly pressed to the hole bottom portion to be largely deflected, so that the spring force is generated in the arrow direction by the deflecting force and applied to the conical shape 5c. When the transport member 3a is slid in the direction of an arrow F to reach designated positioning places of the vertical moving portion and fixed portion, as the conical shape 5c is put in the uppermost position, the conical shape 5c is lowered and the vertical moving portion and fixed portion and the conical shape 5c are engaged with each other. At this time, the spring force is applied from the cam mechanism K to the hole bottom portion. Accordingly, the transport member 3a is positioned in a designated position.

Title: Image forming device
Inventor: KITAJIMA ICHIJI
IPC: G03G21/16
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To eliminate special reinforcement of a frame with respect to a pressing member at the coupling part of a device main body divided into two upper and lower parts. SOLUTION: The upper main body U is received by the spring force of a spring 18 through a slider 21, a slider shaft 23 and a supporting shaft receiving base 22. When the shaft 23 is elevated, a holding lever 30 pressed by a lever pressing spring 32 is turned with a shaft 31 as the center and the shaft 23 enters a slope 36. Thus, the upper main body U is supported by being shared by the spring 18 and the slope 36 of the holding lever 36 pressed by the spring 32. As the result, the spring force of the spring 18 can be reduced and force added to an upper and a lower frame main bodies 9 and 15 closed in a state where the spring 18 is compressed, can be reduced.

Title: Recorder
Inventor: TOYODA SHOJIRO
IPC: G01F1/00
Filed: 1994-12-06
Abstract: PURPOSE: To obtain an abnormality sensing device which can detect abnormality, of which reliability in flow measurement is high, and maintenance is easy, by changing over from a normal transmission signal of flow quantity control to a check signal at the time when failure diagnosis of control loop is to be made. CONSTITUTION: When failure diagnosis of control loop is made, in a check signal transmission means 11, output signal of a flow meter body 6 is changed over from a normal transmission signal to a check signal, and this output is made. In a diagnosis means 12, change in difference pressure, on the basis of a check signal, is detected. And this is compared with a specific reference value, so that an abnormality of a device consisting control loop is detected and thus a sensing signal is outputted. For example, valve opening of a valve 3 is changed by the check signal transmission means 11, so that this corresponding response inputted to the diagnosis means 12 is compared with a response in normal state. Accordingly, it is easily and at any time sensed whether a lead pipe 7 is not clogged and so is in normal state, or not.

Abstract: PROBLEM TO BE SOLVED: To provide a method capable of inserting a shaft with O-ring into a housing hole without increasing the number of housing hole machining processes and breaking and damaging o-rings. SOLUTION: First, a cross hole insertion jig 60 to which an insertion bar 62 is attached is prepared. The part of the insertion bar 62 of the cross hole insertion jig 60 is inserted into the opening section on the side opposite to the opening section of a cross hole 24 opening facing the inner wall side of a housing hole 22 and is moved in the direction of an arrow mark A. When the tip of the insertion bar 62 reaches the nearly same level as that of the inner wall face of the housing hole 22, the insertion bar 62 is prevented from being inserted further. Through this operation, the opening section of the cross hole 24 having been opened facing the inner wall side of the housing hole 22 is clogged by the insertion bar 62, nearly eliminating the difference in level from the inner wall of the housing hole 22.  With the insertion bar 62 inserted into the cross hole 24, a shaft with O-ring is inserted into the housing hole 22.
