Title: Detecting circuit of tracking error signal of optical pickup
Inventor: NAKAMURA MASAFUMI
IPC: G11B7/09
Filed: 1982-06-16
Abstract: PURPOSE:To eliminate a high band component and to reduce the noise generated from an actuator, by eliminating the PCM signal leaked into a tracking error signal without changing the characteristic of a tracking servo loop. CONSTITUTION:A delaying device 9 is connected to the output of a detector 4-1 to delay the output of the detector by a time equivalent to the delay time tau between light spots 1 and 2. Both spot 2 and an optical detector 4-2 have the same PCM signal while the outputs of the preceding spot 1 and the optical detector 4-1 are delayed by the time tau. Therefore the PCM signal component is equal among input signals of a differential amplifier 6, and the output of the amplifier 6 contains no PCM signal component. As a result, no PCM signal component is contained in the input signal of a tracking servo actuator 8. Thus no noise is generated from the actuator 8.

IPC: B23H7/08
Filed: 1983-06-07
Abstract: PURPOSE:To improve in the capacity of an electrode wire ever so better and thereby make highly accurate, stabilized electric discharge machining performable, by forming a specified thick insulating film on a surface of the electrode wire with an electrode manufacturing device. CONSTITUTION:An insulating film of 100-1,000Angstrom  in thickness is formed on a surface of an electrode wire for wire-cut electric discharge machining. In order to form the insulating film into the electrode wire, the following method is used that heating treatment first takes place in pressure oxygen gas, pressure air and glow discharge, then temperature and time are controlled and an oxidation film is formed on a base material surface on which an oxided film is formed. For this electrode wire manufacturing device, there are provided a device which controls the shifting and travel of an electrode 1 opposing a workpiece 5 for electric discharge machining while shifting and traveling the workpiece 5 between guides 4 in a state of imposing some tension on it, a tank 6 which stores oxided film forming treatment water 7 where the electrode wire 1 passes through by control of the above-mentioned device, a conductiv electrode 8 opposed to the electrode wire 1 run past the inside of water in the treatment tank and a treatment power source which makes a circuit between the conductive electrode 8 and the electrode wire 1.

Title: Formation of film for information carrier
Inventor: UCHIDA MASAMI
IPC: G11B7/26
Filed: 1987-04-24
Abstract: PURPOSE:To prevent expansion of surface defects originating from the deposited foreign matter, flaws, etc., on a disk surface by spraying a coating liquid for a hard protective film to the region exclusive of the part near a center hole and drying the coating to cure. CONSTITUTION:The center hole 12 of the disk 11 is coated with a disk-shaped label 17 and thereafter, the coating liquid 19 for the hard protective film is sprayed in the form of mists from a nozzle 18 and is coated on the disk at the time of forming the hard protective film 22. The coating is thereafter dried to cure and the label 17 is stripped to form the film 22. The expansion of the defects originating from the deposited foreign matter and flaws is, therefore, obviated even if the surface has such deposited matter and flaws. The small flaws are conversely embedded and the surface flaws are annihilated. Since the coating liquid 19 is not blown near the center hole, the shape of the center hole does not change at all and the generation of a run-out and surface waving is obviated even if the film 22 is formed.

Title: Auto die bonder
Inventor: TAMAKI KIYOUHEI
IPC: H01L21/58
Filed: 1978-08-24
Abstract: PURPOSE: To conduct dies bonding (or joining) operation automatically by utilizing a lead frame, which is formed adjoining a continuously long hoop material, and providing a breaking-conveying-ejecting machanism.  
     CONSTITUTION: A continuously long lead frame of die bonding agent is cut to the preset series numbers N by a cutting mechanism 10. As joints of the lead frame can cause obstruction to package with resin, etc., the cutting position is electrically controlled, and at the same time, careful arrangement is made so that a metal strip (or adhesive) and a die are not attached onto the lead frame of the scheduled position to be cut included in the joints. For instance, when an independent lead frame length of Q,n 1  W n 3  is integrated, it is controlled to become (n 1 +n 2 +n 3 )÷=Q, and when Q is not an integer, a length of a section including a joint is set to PN but if Q is an integer, a joint comes to a cutting position, and therefore, it is avoided by using P(N+1). By taking such a procedure, a joint is detected 12 for selection of position for cutting 10, a long lead provided with a metal strip 42 and a die 43 is cut and conveyed 11, a cut lead frame containing a joint is ejected.

Title: Thickness slip piezoelectric oscillator and its production
Inventor: ENDO HIDEO
IPC: H03H9/17
Filed: 1991-05-08
Abstract: PURPOSE:To enable a thickness slip piezoelectric oscillator to confine energy and to reduce the CI value even when the piezoelectric plate is made compact by making the thickness of piezoelectric devices placed in the periphery of exciting electrode thinner than the thickness of the piezoelectric plates under the exciting electrode and the thickness of the periphery of the piezoelectric plate. CONSTITUTION:A crystal oscillator piece 1 having an exciting electrode 2 and connecting electrode 3 formed using Cr and Ag on the main surface of the present thickness slip is connected to the end section of inner lead 4 passing through a stem 5 and to the end section of the connecting electrode 3 with solder. By using solder to seal the stem 5 and a case 6 in a vacuum chamber, the crystal oscillating piece 1 is maintained in vacuum. Further, although the crystal oscillating piece 1 has the same thickness in the section where the exciting electrode 2 is placed and in the periphery of the crystal oscillating piece 1, the crystal oscillating piece 1 has a groove so that it can be thinner in the periphery of the exciting electrode 2. Furthermore, the method to prepare the groove is that Ar gas ionized by ion beam spattering is focused using electromagnet and is shooted to the exciting electrode 2 and to the crystal oscillating piece 1 to turn out constituting substances therefrom to make the crystal oscillator 1 in the periphery of the exciting electrode 2 thinner.

Title: Echo canceller
Inventor: UMIGAMI SHIGEYUKI
IPC: H04B3/23
Filed: 1982-06-15
Abstract: PURPOSE:To prevent the divergence of an echo canceller at the time of bilateral talking, by detecting the bilateral talking status by using the instantaneous value of a remaining echo. CONSTITUTION:When a signal higher than some level is inputted, the echo canceller EC starts convergence. Level detecting circuits LD1, LD2 detect the signal level and voice A' level of an echo path, these detected values are compared by a comparator CP, and when the signal level of the echo path is increased, a signal to close, an inhibit gate G is outputted through an OR gate OR to inhibit the input of an instantaneous value of the remaining echo from a remaining echo amplitude detecting circuit ED to the echo canceller EC. Consequently, the compensation of the EC is stopped. When the instantaneous value of the remaining echo exceeds some value even if the signal level of the echo path is not ascended, the bilateral talking status is detected and the inhibiting gate G inhibits the input of the remaining echo signal to the echo canceller EC.
