Title: Disk reproducing device
Inventor: MORIAKI MASAYUKI
IPC: G11B21/08
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To always fix a running characteristic of an optical pickup by adjusting a level of a drive voltage according to a value of a drive current. SOLUTION: An MPU 32 outputs a thread kick signal in response to a power supply. The thread kick signal is amplified by a variable gain amplifier 26 to be supplied to a transfer motor 16 as the drive voltage. The transfer motor 16 is driven by the drive voltage, and the optical pickup is moved from an innermost periphery of a disk to the outermost periphery. Counter electromotive force becomes large as the rotational speed of the transfer motor 16 becomes fast, and the drive current flowing through a coil L becomes small. In the outermost periphery, the rotational speed becomes maximum, and the drive current becomes minimum. The MPU 32 detects the minimum value of the drive current to compare it with a reference value. Then, the MPU 32 corrects a thread gain according to the comparison result. The drive voltage is changed according to fluctuation in a load.

Title: Infrared detector
Inventor: ONO KATSUHIRO
IPC: G01J5/06
Filed: 1987-07-21
Abstract: PURPOSE:To obtain a detector whose inner tube member has a high machining precision and whose input/output terminals can be joined easily, by a method wherein a stem member, the inner tube member and an insulating plate are formed of free-machining ceramic while a cover member and the input/output terminals are formed of an iron-nickel alloy. CONSTITUTION:A vessel having a Dewar structure is constructed by using free-machining ceramic whose heat conduction loss is small and which can be machined with high precision, and by using an iron-nickel alloy which has a thermal expansion coefficient approximating to that of said ceramic. Herein an inner tube member 4 is formed precisely by cut machining, so that the matching with the sizes of a cooling unit can be attained easily. A cover ember 6 can be formed on the iron-nickel alloy. Accordingly, an excellent mechanical strength is attained and high reliability can be secured even when strict vibration-proof and shock-proof properties are demanded. Since the thermal expansion coefficients of these materials approximate to each other, moreover, the security of airtightness of joined parts against a change in temperature can be maintained for a long period.

Filed: 1981-11-14
Abstract: While using a metering apparatus which comprises a metering pump (1) including a vertical, elongate pump cylinder (2), and a piston (3) arranged for axial movement in said cylinder, an accurately determined volume of liquid is transferred from a first vessel (6) to a second vessel (7). The pump (1) is lowered into the first vessel (6), so that the pointed part (2a) of the pump cylinder (2) extends down into the liquid contained by the first vessel (6), and the piston (3) is withdrawn through a distance such that a volume of liquid substantially exceeding the volume to be transferred is drawn into the pump cylinder (2), whereafter the pump (1) is raised. The piston (3) is advanced in the cylinder (2) in order to return part of the liquid, whereafter the piston (3) is withdrawn through a short distance, so that any droplet which may have adhered to the pointed part (2a) of the pump cylinder (2) is drawn into the cylinder (2). The pump (1) is then moved to a position above the second vessel (7) and the piston (3) advanced through a distance which corresponds exactly to the volume of liquid to be transferred plus the distance through which the piston (3) was withdrawn in the preceding procedural step. In this way, the desired amount of liquid is dispensed to the second vessel (7).

Title: Voice storage retrieving system
Inventor: YOSHIDA TAKASHI
IPC: G10L13/02
Filed: 1986-08-04
Abstract: PURPOSE:To reduce a cost and to simplify the program searching of voice message at reproduction by recording a voice message to one side of channel of a sound recording medium and recording an acoustic signal for retrieval to the other one side channel. CONSTITUTION:The sound recording of a backup device is started through a voice input line and a hatched part 13 in the voice message 11 and a hatched part 13 in a retrieval tone signal 12 are recorded through the voice input line and the retrieval signal input line after a proper interblock recording (silent period of nearly 5sec). In listening to the recording, a stereo device provided with a conventional program searching reproduction function is used to apply recording while program-searching. Since well known program search function of a stereo sound recording device detects a part 15 to which both tracks are silent simultaneously, even if the long time silent part 16 exists in the voice message, the program searching function does not malfunction. Thus, since the conventional stereo recorder is used for backup of the voice storage retrieving device, the voice message is program-searched inexpensively surely.
