Title: Signal processing apparatus
Inventor: HOTTA RYUTARO
IPC: H04L25/03
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a reproducing apparatus by which the equalization error amount or the BER of an equalization reproducing signal is made minimum. SOLUTION: A variable-gain amplifier 15 amplifies an input signal, and a filter 16 outputs an amplified signal at a prescribed transmission characteristic. An equalizer 17 equalizes and outputs a filter output signal at a prescribed characteristic, and a converter 18 analog-to-digital-converts an equalization signal. In addition, a maximum likelihood decoder 19 generates a most likelihood signal train from the output signal of the converter, and a decoder 20 decodes the signal train. In addition, a gain-amplifier control circuit 24 generates the control signal of the variable-gain amplifier 15. An equalization-error detection means 23 detects the equalization error amount of an equalization reproducing signal, and an amplitude correction means 23 gives a signal to the variable-gain amplifier circuit 24 in order to correct the amplitude of the equalization reproducing signal.  An input/output bus 35 gives an instruction signal to the amplitude correction means so as to make the equalization error amount minimum.

Abstract: PURPOSE:To eliminate surface shake for rotation of an information recording medium by directly joining a disk-shaped resin film to a disk-shaped substrate. CONSTITUTION:A disk-shaped resin substrate 11 (21) and a disk-shaped resin film 21 (22) are joined to constitute an information recording medium 10. A hole part 23 is provided in the center of the substrate 21, and a recording layer 24 is provided between an inside peripheral non-recording area 25 and an outside peripheral non-recording area 26, and areas 25 and 26 are provided with annular projections 28-a and 28-b. The film 22 is flexible and is provided with a hole part 29 in the center. The film 22 is brought into contact with the surface on the layer 24 side of the substrate 21 and an ultrasonic wave is applied to projections 28-a and 28-b of the substrate 21 to fuse them and they are joined, thereby producing the medium 22. Since they are joined without a spacer, the medium is not affected by the precision of the spacer and surface shake for rotation is reduced.

Title: Camcorder
Inventor: KUSANO YASUO
IPC: H04N5/232
Filed: 1990-09-03
Abstract: PURPOSE:To prevent erroneous image pickup effectively by using an image pickup stop means connected in series with a video recording start/stop switch electrically so as to interrupt a line of the above switch when the camcoder is tilted at a predetermined angle or over thereby stopping the pickup. CONSTITUTION:For example, when a camcoder is tilted by 90 deg., since a conductive liquid 3 is always kept horizontal, an electrode 2a is exposed from the conductive liquid 3 and a sensor 1 is turned off. Thus, even when a video recording start/stop switch 5 is closed, the circuit is entirely turned off and pickup is stopped. Then the sensor having the conductive liquid 3 having a couple of electrodes 2a, 2b is provided to the camcoder. Then erroneous pickup due to mis-operation of the video recording start/stop switch 5 is prevented by utilizing on/off of the electrodes 2a, 2b due to the tilted camcoder.

Title: Driving method of thermal printing head
Inventor: KATAKURA SHINICHI
IPC: B41J2/36
Filed: 1983-12-13
Abstract: PURPOSE:To enhance the quality of printing by avoiding change of the size of printed elemental points at the speed of spacing by controlling the drive voltage and time of the head as functions of speed by the spacing speed. CONSTITUTION:In a controller 1, prior to printing, the inverse number of square root of spacing speed (printing speed) is calculated and sent out to a D/A converter 9 as head drive voltage control, where the output is converted into analog control signal and sent out to a head voltage generation circuit 10. The control signal for printing is put in the controller 1 through A/D converter 6 by a motor 5, and printing signal at feedback pulse position is sent out to the thermal head drive circuit 2 as time inversely proportional to spacing speed. Voltage generated in the circuit 10 is supplied to a thermal head 3 only for said time period for printing. The change in the size of elemental points printed at the spacing speed can thus be avoided.

Title: Pressure retainer
Inventor: HARA KOICHI
IPC: F15B20/00
Filed: 1987-09-18
Abstract: PURPOSE:To shut off a main circuit quickly by moving a spool to close a variable throttle when something is wrong with a solenoid-controlled valve. CONSTITUTION:During operation of cylinders C1, C2, when a solenoid-controlled valve S1 on one side gets out of order and pressure at the side of a feed-exhaust port 4 goes down, by way of example, a fluid in the cylinder C1 flows back, passing through a variable throttle 22. At this time, a pressure difference is produced in the front and in the rear of this variable throttle 22, thereby front pressure in the variable throttle 22 acts on a pressure chamber 11 at the lower side by way of a flow port 25 and a through port 17, and the rear pressure acts on a pressure chamber 10 by way of a flow port 24 and a through port 16. Consequently, the pressure difference is produced between both pressure chambers 10, 11, and a spool 8 goes up against a spring 14, closing the variable throttle 22 and it holds the load of the cylinder C1.

Filed: 1987-09-18
Abstract: PURPOSE:To evade competition and to maintain a proper operation by disposing flags indicating a resource using state for plural means and changing a cycle for repeating a reference for every means when other means detects the incapability of an access. CONSTITUTION:The plural using state flags indicating whether the plural means A, B use the sharing resource 10 or not under a control of its own are disposed correspondingly to the plural means, and at the time of generating an access request to the resource, the flag relating to the control of its own is changed to 'during using' and the flag of other means in referred to decide an accessibility. At the time of the incapability of the access or the completion of the access, the flag of its own is brought into 'not used' and especially, at the time of the incapability of the access, the reference of the flag of other means is repeated at a cycle different from other means. Accordingly, since the cycle is different, a timing i coincides to bring no incapability of the access.

Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To contrive to facilitate leveling work of an excavated bottom by providing a fit-in section which fits in the tip of a claw of a bucket of a shovel- based excavating machine and an insertion hole into which a fixture is to be inserted on one side of a plate and forming a flat claw on the other side edge. SOLUTION: A flat claw plate 1 forms a fit-in section 2 which comprises the same number and same shape of recessed parts identical to the claws of a bucket on one side 1a of the plate 1 and provides a flat claw 4 on the other side edge 1c. In the case when the plate 1 is fixed with the bucket, the fit-in section 2 is fitted into the claw of the bucket, thereby aligning a through hole 3 with a through hole preliminarily formed in the claw and then a fixing pin is inserted into these through holes. This construction makes it possible to eliminate the need to bring in a heavy clawless bucket to a construction site to exchange and remove the bucket in a short time and easily since the plate 1 is small in size and light in weight and remove the danger which may bury a worker alive and furthermore enhance workability since leveling work of an excavated bottom is mechanized.
