Title: Digital computer interface for simulating and transferring CD-I data
Inventor: STEWART DAVID
IPC: G11B20/00
Filed: 1991-02-27
Abstract: Provision is made for at least two levels of buffering in compensating for the delays from and out of the Unix workstation, thus achieving the required timebase correction. At the first level of buffering there is an eight Megabyte memory coupled to the VME bus of the Unix workstation over a disc simulator processor, which is sufficient to store about 45 seconds of audio data. The secondary level of data buffering is provided by an interface board which further buffers an additional 1.5 milliseconds between the first level of buffering and the second level of buffering. The outbound interface comprises three separate registers to process the compact disc data when they are retrieved from the digital computer. Each of the registers comprises a plurality of FIFO registers. The first register receives outbound audio samples. The second register receives Q subcode data. The third register receives optionally QRSTUVW or RSTUVW subcode data. Instead of burdening the Unix software with the task of interleaving the subcodes, the interface hardware manages and manipulates the subcodes. An inbound interface similar to that of the outbound interface is also provided for receiving and storing compact disc data. Thus, the storage and replay of compact disc data are achieved simultaneously. <IMAGE>

Title: Semiconductor switching device with reduced switching loss
Inventor: FURUHATA SHOICHI
IPC: H03K17/00
Filed: 1992-02-28
Abstract: A semiconductor switching device including a first semiconductor element such as IGBT A and a second semiconductor element such as IGBT B connected in parallel. The IGBT A has a low saturation voltage and a long fall time, whereas the IGBT B has a high saturation voltage and a short fall time. An input resister R is connected to the gate of IGBT B, and a common drive signal is applied to a gate of IGBT A, and to a gate of IGBT B through the input resister R. The IGBTs A and B are driven by the common drive signal so that the semiconductor switching device is turned off in the short fall time of the IGBT B. The switching speed is increased and the switching loss is decreased. Only a single drive circuit is enough for driving the device, enabling the miniaturization and low cost of the driving circuit. The input to IGBT A also may be via a resister provided its value is smaller than the input resister R. The first and second elements may be bipolar transistors or MOSFETs, integrated circuit details are described (Figs 9A-9C and 10A-10G). <IMAGE>

Title: Rotation control device for sewing machine motor
Inventor: MORI SHUSHIN
IPC: D05B69/18
Filed: 1992-06-09
Abstract: When a sewing machine is locked during stitching of a thick fabric, the rotational direction of a sewing motor (M) is reversed after a predetermined time interval. When motor speed (Sj) is detected in circuit (9b) as falling below a threshold value a circuit (9c) instructs the motor control circuit (7) to reverse the motor after a time interval set by a timer (T). The motor may then be driven in an alternating manner with a cycle set by the timer until the needle has penetrated the fabric or alternatively the motor may be stopped following one or two attempts and manual intervention is required. An alternative embodiment uses monostable multivibrators in the circuit (9c). The motor may be of AC, DC series commutator or DC brushless type. <IMAGE>
