Title: Reference point deciding circuit
Inventor: TANAKA TADAAKI
IPC: H04N5/21
Filed: 1987-04-22
Abstract: PURPOSE:To improve performance including elimination of near ghost or the like by deciding a reference point from a cross point between a mean value of two point levels apart sufficiently before and after the trailing edge of a vertical synchronizing signal and a level of the trailing edge of the vertical synchronizing signal. CONSTITUTION:A tap gain control circuit uses a 1st base point deciding section 12 to decide the reference point roughly based on the mean value or the like of levels and the read timing of a read section 15 is adjusted coarsely based thereupon. In parallel with the adjustment, a 2nd reference point deciding section 19 decides the reference point with high accuracy based on correlation and the read timing by the read section 15 is adjusted minutely based thereupon. Thus, the reference point is decided with very high accuracy of one sampling interval. As a result, in applying the titled circuit to a ghost eliminating device, the performance including near ghost elimination is improved remarkably.

Title: Automatic frequency control system
Inventor: SATO KEN
IPC: H03J7/02
Filed: 1989-04-19
Abstract: PURPOSE:To always attain stable accurate frequency control by controlling the frequency of an IF signal based on a mean value of frequency deviation of an intermediate frequency(IF) signal for plural frequency reference signal periods. CONSTITUTION:An output of a differential amplifier 10 being the result of comparison between a frequency reference signal and a reference level for each of different frequency reference signals is subject to sample-and-hold by sample-and-hold circuits 14-17 respectively and a mean value of the frequency deviation of the IF signal for four frequency reference signal periods is detected by an adder 18 and a divider 19. Then based on the detected mean value, the oscillated frequency of a voltage controlled oscillator 13 is varied to control (correction of deviation) of the frequency of the IF signal. Thus, fluctuation of the signal level of the frequency reference signal due to noise is cancelled and even when the noise superimposed on the frequency reference signal due to deterioration in the S/N of the demodulated output is increased, the always stable frequency control is attained.

Title: Method and device for casting molten metal close to final dimension
Inventor: RAIMUNTO BURIYUTSUKUNERU
IPC: B22D11/14
Filed: 1995-03-22
Abstract: PURPOSE: To improve the dimensional accuracy of the cross section of solidified metal by acting ultrasonic vibrations of a specific oscillation frequency to a passage for casting the molten metal. CONSTITUTION: The passage 2 is mounted with an inclination of an angle W at the lower part of a metallurgical vessel 1. The molten metal in the passage 2 lower than a molten metal level S is heated by a heater 5 to prevent the solidification of the molten metal. The molten metal in the passage 2 upper than the molten metal level S and lower than part thereof is cooled to solidify by a cooler 6. A vibration generator 7 applies the ultrasonic vibrations of 5 to 20 kHz to the passage 2. The vibration component (a) facing a flow direction F delivers the molten metal or solidified metal in the passage 2 toward an outlet opening 3. The vibration component (b) facing perpendicular the flow direction F acts to prevent the sheath of the solidifying molten metal from sticking to the wall of the passage 2.  The vibration component in a direction transverse to the flow direction F acts to uniformly distribute the molten metal over the entire part of the width of the passage 2. Then, the casting approximate to the dimensions and shape of the outlet opening 3 may be produced.

Title: Split type thermal head
Inventor: ISHIZU AKIO
IPC: B41J2/335
Filed: 1983-06-06
Abstract: PURPOSE:To prevent the separation in the joint part of a ceramic substrate during use, by dispensing with the fixation with a heat sink by an adhesive by forming an intermediate assembly wherein a fixing plate is secured to ceramic substrates over the total length or a partial length thereof including the mutual connection part of said substrates. CONSTITUTION:A fixing plate 5 having the same coefficient of thermal expansion as each of ceramic substrates 2 is secured to the connection part of said substrates 2 by an adhesive. The formed intermediate assembly is placed on a heat sink 3 coated with silicone grease having good heat dissipating property and resistors 1 are secured to the ceramic substrates 2 by a press plate after the positions thereof are determined with respect to the heat sink 3 to form a thermal head. Because the ceramic substrates 2 and the fixing plate 5 have equal coefficient of thermal expansion and no bimetal effect is generated, the warpage of the ceramic substrates 2 is not generated. In addition, because the fixing plate 5 is secured only to a part of the total length of the intermediate assembly, the connection part 4 is hardly separated even if the thermal head generates heat during use. Even if the fixing plate 5 is secured to the ceramic substrates 2 over the total length thereof, the separation of the joint part 4 can be regarded as negligible because the coefficients of thermal expansion of the ceramic substrates 2 and the fixing plate 5 are low.

IPC: H04L12/40
Filed: 1989-04-18
Abstract: PURPOSE:To surely detect a station-down of the called party by providing a means sending mutually to detect the station-down state of the called party and sending a command for check and a means discriminating whether or not just after the opposite station rises with the command. CONSTITUTION:An echo S command from a communicating computer A is a command to be sent for checking a station-down state of the called party when the computer A rises and an opposite station receiving the echo S command returns an echo S answer. If a computer B is in down-state during the check while the echo command is used between the computers A and B and restored, since the computer B receives the first echo just after the leading as a response to an echo R, the echo S response is returned. Thus, the restoration of the opposite station is recognized and the restart processing is executed.

Title: Automatic tube size-adjusting and cutting device
Inventor: OSAWA HIROYUKI
IPC: B26D3/16
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To automate size-adjusting and cutting operations of a tube1 which requires manufacture under an internal pressure-maintained condition. SOLUTION: A tube 1 whose size is adjusted is positioned by a positioning means. The positioned tube 1 is received by clamps 24A, 24B which blockably- clamp the positioned tube 1 for cutting operation. After the cutting process, the end of the tube 1 on the delivery side is welded. After internal pressure is increased by a pressurized air supply means, the tube1 on the size-adjusting side is welded. As a result, cutting and welding operations can be conducted under the condition where the tube 1 is closed so that internal pressure may be maintained by the clamps 24A, 24B, thus it is possible to conduct bundle operation continuously and automatically.

Title: Face to face joining method
Inventor: NAYAMA RISUKE
IPC: B23K26/32
Filed: 1986-04-30
Abstract: PURPOSE:To solder materials which are largely different in the coefft. of thermal expansion without using a buffer material by disposing the materials which are different in the coefft. of thermal expansion in such a manner that the joint surfaces thereof contact each other and irradiating an energy beam on the side of the material having the smaller coefft. of thermal expansion. CONSTITUTION:The material 3 having the smaller coefft. of thermal expansion and the material 4 having the larger coefft. of thermal expansion are disposed in such a manner that the joint surfaces thereof face each other. The energy beam 2 such as laser beam is irradiated on the side of the material 3 having the smaller coefft. of thermal expansion to join the materials. The material 3 is first heated in this case, then the material 4 is heated by heat conduction and therefore, a temp. gradient arises between the materials 3 and 4. The coefft. of thermal expansion between the materials 3 and 4 is, therefore, equalized when the output of the beam 2 is regulated to attain the adequate temp. gradient. Since the generation of thermal stress by a difference in the coefft. of thermal expansion is thereby prevented, for example, an Mo sheet and SUS304 sheet which are largely different in the coefft. of thermal expansion are joined without troubles even if the buffer material is not inserted.
