Abstract: PURPOSE:To enable to reduce the changes in the diameter of a grown crystal and the rate of crack generation by disposing a spiral heat-releasing section in a temperature-holding space on a crucible heated by a high frequency induction heating. CONSTITUTION:A current is applied to a high frequency induction-heating coil to heat a crucible 2 charged with a raw material for melting the raw material. A seed is brought into contact with a melted liquid through the center of a heat-releasing coil 5 comprising a spiral metal pipe disposed above the opening of the crucible 2 and an inert gas is flowed into the coil 5 to exchange the heat of grown crystal 6 with the inert gas. The temperature of the coil 5 is detected with a temperature sensor 3 attached to the coil 5 and the detection signal is inputted to a controller 7 to operate a electromagnetic valve 4, thereby controlling the flow volume of the inert gas in the coil 5 to control the amount of heat from the crystal 6.

Title: Circuit for detecting tip of synchronizing signal side
Inventor: TANAKA SEIICHI
IPC: H04N5/93
Filed: 1988-03-31
Abstract: PURPOSE:To improve the tip detection performance of a synchronizing signal by detecting the tip value of the synchronizing signal side of a video signal when the high frequency component is small in the specified period and storing and updating the detected tip value for each specified period. CONSTITUTION:A video signal of linearity is subject to A/D conversion and a signal LPFY is formed except high frequency noise and a color signal component through an LPF. A minimum value detection circuit 24 extracts the high frequency component of the signal LPFY by an HPL 28 and when the absolute value is smaller than the setting value, an output ENABLE 'H' of the comparator 30 is received. The content of the 1st register built in is transferred to the 2nd register for each prescribed period including at least one synchronizing signal by the input and the 1st register is initialized at a maximum value and the output of the 2nd register reaches a minimum value MIN. The PLL circuit 26 is operated based on the horizontal synchronizing signal and the output is phase-locked with the signal LPFY and its leading controls the detection circuit 24. The leading is set to the back porch of the horizontal blanking period and the signal MIN is shorted and updated to detect the tip value of the synchronizing signal from the video signal with excellent S/N.

Abstract: PURPOSE:To realize an excellent picture processing by preventing a color balance around a threshold level from being unbalanced. CONSTITUTION:A white level discriminator 814 outputs an 'H' level when other color exceeds threshold level data 804 while defining a minimum level among R, G, B colors as a reference level in the case the discriminator 814 is in the level other than 'L' and the discriminator outputs an L level when the level is the threshold level data 804 or below. That is, a white level point at the time of binarization can be set in threshold level data 801-803, and the binarization is implemented with a level difference between the threshold level data 804 and the minimum value, then the binarization is implemented without black level processing from a low density region to a high density region. Furthermore, color slippage hardly takes place.

Title: Synchronizing device for power transmission
Inventor: FUKUHARA YUICHI
IPC: F16D23/06
Filed: 1987-03-31
Abstract: PURPOSE:To reduce diameter and axial dimension and to reduce weight and cost by providing inner and outer conical faces at radially outside of respective power transmission splines and approaching respective power transmission splines of clutch hab and gear each other thereby eliminating a key. CONSTITUTION:Upon application of shifting force onto a sleeve 21 in the direction of a gear 25, a synchronizer ring 23 moves by the distance of a gap, and a projection 28 on the ring contacts with an index spring 24 to produce pushing force. Consequently, the spring 24 enlarges radially and tries to ride over a conical face 23 thus producing axial resisting force which causes frictional torque in rotary direction. Consequently, the projection 28 which had been free in a groove 27a contacts with one side of the groove 27a and positioned in place. Upon further shifting of the sleeve 21, the spring 24 rides over the conical face 34 and thereby the sleeve 21, the ring 23 and the spring 24 advance in shifting direction this contacting a beveled face 38 of the projection 28 with a beveled face 37 formed between the grooves 27a, 27b. Consequently, the ring can be contained in lack of fill portion of gear when the sleeve 21 is shifted, resulting in shortening of axial dimension.

Title: Doctor holder
Inventor: INGO KEEPURAA
IPC: B41F9/10
Filed: 1990-03-29
Abstract: PURPOSE: To uniformly bring a doctor blade into contact with a printer cylinder in an entire length by cutting the cylinder while forming an inclined angle to a lengthwise axis of the cylinder in plane in such a manner that a shorter split line of an ellipse is equal to a radius of the cylinder and a longer split line is longer than the length of the cylinder. CONSTITUTION: When a plane E2 perpendicular to a reference surface and perpendicular to a longitudinal axis A-A of a cylinder 1 of the printing machine passes an arbitrary point Q of a cutting line Q1-Q2, the cylinder 1 is cut in the shape of a circle G' in the shape of a cylinder H' of a sectional elliptical shape. When the plane E2 is folded at 90 on a reference surface, parts of the circle G' and the ellipse H' are obtained. In this case, a shorter split line b' of the ellipse H' is equal to a radius (r) of the cylinder 1, and a larger split line (c) is equal to a length of a line segment T1-T2. Thus, even when a flexible doctor blade of a normal plane shape is used, its edge is brought into contact with the cylinder of the machine over the entire length.

Abstract: PURPOSE:To reduce pump sounds generated by the fluctuation of an outer rotor by ensuring a zero or more distance between the tops of internal teeth of an inner rotor and external teeth of the outer rotor when these tops confront each other. CONSTITUTION:The internal teeth 18a of an inner rotor 18 formed of a trochoid curve mesh with the external teeth 20a of an outer rotor 20, and both rotors 18, 20 are incorporated under the eccentric condition in a receiving section 24 of a pump housing 22. When the rotation of the outer rotor 20 along with the rotation of the inner rotor 18 causes the top 18b of the internal teeth of the inner rotor 18 to confront with that 20b of the outer rotor 20, the center of the outer rotor 20 is set such that a zero or more of distance between both tops 18b, 20b is ensured.
