Abstract: Disclosed is an apparatus for detection of write protect data written on an optical disk by simultaneously reading the data during writing using differential detection and disabling further writing if write protect data is present. The write protect data is the same format as other data written on the optical disk and is written as the first byte of data on all data fields. The data is written in a fixed-block format defining a symbol having a predetermined number of symbol positions and a predetermined number of holes which may be written at the symbol positions, an equal number of holes at odd and at even positions. The write protect symbol has holes written at symbol position numbers two and five. During the writing of a write protect symbol, the laser is operated at read power before it is operated at write power and a signal associated with the hole associated power of the reflected beam is sampled at position number eight of the previous symbol and at position number one of the write protect symbol. The hole associated power at position number one will be significant if a hole was previously written at position number two. The read signals at positions one and eight are compared to each other. If the position number one signal exceeds that at number eight by a predetermined differential, a hole was previously recorded at position number two, indicating the presence of a previously written write protect byte of data.

Abstract: In a television receiver, a contrast control signal for controlling the amplitude of a video signal is a function of a manual (20) contrast control component provided by a viewer, and an automatic contrast control component provided by a light sensitive circuit (50) responsive to ambient light conditions. A "soft" limiter (80) limits the value of the control signal to prevent a displayed image from being extinguished due to excessive video signal attenuation in response to the control signal. The manual control component is provided by means including a duty cycle control device such as a binary rate multiplier (24) or pulse width modulator.

Abstract: A rubber-modified phenolic resin composition con­tains a novolak-type phenolic resin in which at least one modifying agent selected from the group consisting of an ABS resin and an MBS resin is homogeneously dispersed. The composition has good impact resistance and thermal shock resistance. The composition is pre­pared by adding at least one modifying agent described above to a novolak-type phenolic resin which is heated and melted at its softening point or more, so that the modifying agent is homogeneous dispersed in the resin. The resin composition is suitably used as a curing agent for an epoxy resin encapsulant for sealing electronic devices.

Abstract: A method to detect and avoid erroneous message de­combining in the switching nodes of message combining multistage interconnection networks used to connect the multiple processors to the multiple memory modules of the shared memories used in parallel computing systems. The method assigns a unique ID to each switch and tags each combined message with it. This ID is also tagged to the reply messages. During decombining the message's ID is matched with the switch's ID, if they do not match the message is not decombined. According to a further feature of the invention, it is possible to provide sufficient information in the ID field to allow a routing error to be detected.

Abstract: An image motion vector detecting apparatus includes a low-pass filter (12, 12′) for suppressing a spatial high frequency component of an image signal in one or both of the horizontal and vertical directions, and a high-pass filter (13) for suppressing a spatial low frequency component of an image signal in one or both of the horizontal and vertical directions. Using an image signal which has passed through the filters, a correlation value for discrete shifts is obtained through a matching operation. Based on the obtained correlation values, a correlation value for continuous shifts is estimated through interpolation processing. A shift having a minimum correlation value is calculated to detect an image motion vector.

Abstract: A sensor for use with a rate-responsive pacemaker is disclosed which is responsive to blood oxygen content, thereby allowing the cardiac rate of the pacemaker to closely mimic the natural response pattern of the heat to changing physiological need. The sensor integrates the output from a photosensor driven by blood-reflected light from an LED, and when the integrated output reached a predetermined threshold latches the circuit, enabling the use of time to indicate the level of blood oxygen content. The sensor thus advantageously requires neither a voltage double in the driving circuitry, or an analog-to-digital converter in the output circuitry, reducing both complexity and power consumption of the blood oxygen sensor.

Abstract: A data flow controller (180). A serial communications card (11) provides an interface between a remote transmitter connected to a serial port connector (20) and a host device (10). The card (11) contains a UART (14) which has a buffer. A counter (151) counts the number of bytes received by the UART (14) since the last time that the host (10) read all the data in the buffer. If the number exceeds a predetermined portion of the buffer capacity the counter output (Q11) will go high, thereby disabling the counter and sending a control signal (DTR, RTS) to the remote transmitter to stop sending data. Once the host (10) has read all the data in the buffer the UART (14) provides a signal (-RXREADY) which resets the counter (151), thereby causing the output (Q11) to go low, thereby allowing the remote transmitter to resume sending data. The counter (151) is held in a reset state until the buffer has received at least one byte of data. Data flow control is therefore obtained without the intervention of the host (10).

Abstract: The charged-particle beam apparatus according to this invention is of the type in which a specimen is inserted between the upper and lower magnetic poles of an objective lens (1), and is constructed such that stages (9a, 9b, 11, 12), which are used to move a specimen in a desired direction, are mounted one on top another from the bottom wall of the objective lens (1), thus preventing the specimen from being affected by external vibration. Devices (9c, 30, 31, 32, 33, 100), which do not generate a magnetic field, are used to drive the stages. This enables the drive devices to be directly connected to the stages, so that the stages are moved accurately.
