Title: Servo control circuit for optical disk apparatus
IPC: G11B7/095
Filed: 1990-01-09
Abstract: An automatic servo gain control system for an optical disk 
player apparatus is capable of controlling an open-loop servo 
gain to be constant, regardless of parameter variations in­
cluding variations in the optical head actuator gain. The 
system includes a gain control circuit that varies a gain 
for a first signal (a) indicative of a positional relationship 
between the optical head and an optical disk based on a second 
signal (b) providing light intensity information. The system 
further includes an oscillator (11) that produces an output 
at a frequency within a servo frequency band of the optical 
head actuator and that is introduced into a servo loop via 
an operational amplifier (7). Signal (e, f) values at an input 
side and an output side of the operational amplifier (7) in 
the servo loop are compared so as to vary the gain for the 
first signal (a) based on a difference between the input and 
output signal (e, f) values. The system operates to control 
the input and output signal (e, f) values to be at a predeter­
mined rate, thereby keeping the open-loop servo gain constant.

Title: Blade sharpener
IPC: B24D15/08
Filed: 1991-09-16
Abstract: A blade sharpener of the kind having a pair of overlapping plates (8) which are relatively arranged to form a vee shaped sharpening recess (10) between them. Each of the opposite sloping sides of that recess (10) is formed by an operative edge (9) of a respective one of the two plates (8), and each of those edges (9) extends between a front face (12) and a back face (14) of the respective plate (8). A relatively sharp corner (13) is formed between each operative edge (9) and the back face (14) of the respective plate (8), and a relatively blunt, e.g. rounded, corner (11) is formed between each operative edge (9) and the front face (12) of the respective plate (8). The plates (8) may be mounted on a member (6) which can pivot between a position at which the plates (8) tilt forward and a position at which the plates (8) tilt back. Spring means (27,28) may be operative to engage the back edge of a blade located in the recess (10) so as to press the cutting edge of the blade against the plates (8). The arrangement is such that longitudinal movement of a blade through the recess (10) in a direction towards the plate front faces (12), causes the sharp edges (13) of the plates (8) to be operative to sharpen the cutting edge of the blade, whereas in the reverse direction of the blade the blunt edges (11) come into contact with the blade cutting edge so that sharpening of that edge does not occur. <IMAGE>

Title: A semiconductor memory with a flag for indicating test mode
IPC: G11C29/46
Filed: 1991-08-12
Abstract: An integrated circuit having a normal operating mode and a special operating mode, such as a special test mode, is disclosed. The special test mode is enabled by a series of signals, such as overvoltage excursions at a terminal, rather than by a single such excursion, so that it is less likely that the special test mode is entered inadvertently, such as due to noise or power-down and power-up of the device. The circuit for enabling the test mode includes a series of D-type flip-flops, each of which are clocked upon detection of the overvoltage condition together with a particular logic level applied at another terminal; multiple series of flip-flops may be provided for multiple special test modes. Additional features include the provision of a power-on reset circuit which locks out the entry into the test mode during power-up of the device. Acknowledgment of the entry into test mode is provided by the presentation of a low impedance at output terminals while the device is not enabled; chip enable of the device causes the device to exit the test mode. Once in test mode, the output enable terminal of the device can provide a chip enable function. <IMAGE>

Abstract: A facsimile machine for single sheets comprises an ink-jet printing head (54) and a line feed device (41) mounted upstream of the printing line (59) to make the sheet (50) advance incrementally. A technical problem of the machine is that of printing adjacent to a trailing edge of the sheet, and that it should be of relatively low cost. An extraction mechanism (82) is provided, having driven rollers (80,85) which may be activated from a state of disengagement with a partially printed sheet to a state of engagement with the sheet. The sheet is drawn forward sufficiently to enable the head to print lines adjacent to the trailing edge of the sheet. The extraction mechanism is actuated when a given reference position of the sheet with respect to the head is detected. A single service motor (84) and suitable cam means (86) drive the special mechanisms of the machine. <IMAGE>
