Title: Electronic watermark generating method using quantized encoding parameter and method for the watermark
Inventor: MORIYA TAKEHIRO
IPC: G10L19/018
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To embed watermark information without changing the bit string of a regular compression code and a decoder by changing the value of the parameter of control on the encoding processing of vector quantization in corresponding to watermark information. SOLUTION: An input signal from a terminal 11 is compressed/encoded by vector quantization in an encoder 12 and encoding output is outputted from a terminal 13. Watermark information is inputted to an encoding parameter control part 15, and the control parameter of encoding in the encoding processing is chanted slightly according to watermark information. A compression bit matrix (encoding bit string) outputted from the encoder 12 is changed, and the watermark information is embedded into the compression bit matrix. The weight coefficient (r) of vector quantization is used as the control parameter of encoding. Normally, a value of about r=0.7 is used. For inputting watermark information, it is set to be r=0.65 if watermark information is '0', and to be r=0.75 if it is '1'.

Title: Spectacle frame
Inventor: TAKEUCHI RYOZO
IPC: C22C19/03
Filed: 1994-05-24
Abstract: PURPOSE:To provide a spectacle frame which facilitates attaching and detaching of lenses and prevents dislodgment of the lenses from rims. CONSTITUTION:The rims 2 holding the lenses 1 are disconnected in outside positions and both ends of V-shaped mitres 5 for connecting temples are connected to both ends 3, 4 of the disconnecting parts. These mitres 5 consist of a shape memory alloy and have a shape nearly closed at both ends in the memory state thereof. The rims 2 are reduced in diameters and are fitted into grooves 7 when both ends of the mitres 5 are pushed to open above and below and the mitres 5 are released after the outer peripheries of the lenses 1 are placed along the rims 2. Further, the rims 2 tend to be reduced in the diameters and, therefore, the tightening force acts on the lenses 1 and the lenses 1 are stably held at the rims 2. The rims 2 are expanded in the diameters and the tightening force of the rims 2 by the lenses 1 is released when both ends of the mitres 5 are pushed to open above and below in the state of mounting the lens 1. The lenes 1 are thus removable.

Title: Initial transmission system for scramble data
Inventor: YAMAMOTO KAZUHISA
IPC: H04L7/08
Filed: 1984-05-31
Abstract: PURPOSE:To scramble a data signal securely even in the beginning of signal transmission by starting the scrambling of a frame synchronizing pattern at the head when only the frame synchronizing pattern is sent out without any data. CONSTITUTION:A switch SW26 is placed at the side of a contact (a1) in the beginning of data signal transmission to select the output of an all-0 pattern generator 23. Contacts (b1) and (b2) are switched and broken by an SW27 at a specific period under the control of an SW switching control circuit 25 to select the frame synchronizing pattern from a frame synchronism generator 24 and the all-0 pattern from the generator 23 alternately, generating specific data. A scramble starting circuit 29 monitors the operation of the circuit 25 and closes an SW28 when the SW27 is connected to the contact (b1) to send the frame synchronizing pattern containing 1 to the self-synchronizing type scrambling circuit 30 composed of an exclusive OR circuit 5 and a scramble signal generator 6. Consequently, when a signal which is not the all-0 signal is inputted, the signal is scrambled securely even if following data consists of successive 0s.

Abstract: PURPOSE:To prevent the increase of scale in call processing program and also to facilitate the easy change in program such as addition, deletion, etc., by setting the state (e.g., busy, all) of an upper call and deciding a task according to the upper call state, an input event and a task decision table. CONSTITUTION:In case such a task that has the common state of each call to a specific input event type is designated, the state of a high-order call representing the states of calls is set instead of a case where an input event is set at the state of each call. Then a task is decided. For this purpose, a task decision table 22a is provided to a main memory 22 of a high performance terminal 2. Then a call state table 220 of the table 22a stores states 809 all, 907 busy and 908 all of an high-order call in addition to each call state. While an event type-based table 221 stores the input event types (incoming request, data information request, etc.) for execution of a common task. Furthermore a service counter table 222 stores the task names (transfer service, store service, data information service, etc.) which should be executed according to the stored input event types.

Title: Reproducing device for disk
Inventor: NAKAGAWA MUNEKAZU
IPC: G11B17/04
Filed: 1994-05-24
Abstract: PURPOSE:To control the operation of a reproducing device for disk without making the loading structure of the device more complicated by arranging a mark for detecting disk number and another mark for detecting stopping position on the same straight line along the moving direction of a disk tray. CONSTITUTION:A photosensor 43 is positioned so that the projecting piece (m) or (n) of a mark for detecting stopping position can pass through the space between the light source section 43a and light receiving section 43b of the sensor 43. Therefore, a mark (o) for detecting disk number arranged on the straight line as that of the projecting piece (m) or (n) can also pass through the section between the sections 43a and 43b. When the photosensor 43 is positioned in such a way, the structure of a disk reproducing device can be simplified, because one photosensor 43 can detect both marks for detecting disk number and stopping position.

Abstract: PURPOSE:To stabilize a spindle motor control by providing a changeover circuit and highly setting a gain of a frequency characteristic of a main signal amplifier only at the time of a seek operation for moving an optical pickup from the inner circumference to the outer circumference. CONSTITUTION:In the optical disk reproducing device for optically reading out a signal recorded on a disk at a constant linear velocity, a signal for forcedly moving the optical pickup from the inner circumference to the outer circumference of the disk is also sent to a changeover circuit 4 from a traverse motor control device 12, and when the forced signal is received by the changeover circuit 4, the frequency gain of the main signal amplifier 3 is changed, so as to raise the frequency characteristic gain of the amplifier 3 in a band of high frequencies and small amplitudes of a read signal. By this method, high amplitudes and low amplitudes of the read signal can be equalized, and even when a data slice level is lowered, the spindle motor control by a seek control can stably and promptly be carried out.
