Title: Twin tub type washing machine
Inventor: FUSHIYA MITSUJI
IPC: D06F29/02
Filed: 1990-06-06
Abstract: A twin tub type washing machine includes a dehydration tub (21) driven by a dehydration motor (22), a brake (24) including a braking member (29) moved into contact with and away from a rotational member (27) so that the dehydration tub (21) is braked, an operation motor (33) driven to move the braking member (29) into contact with and away from the rotational member (27), and a control circuit. When the dehydration operation is initiated, the control circuit operates to start the operation motor (33) one or two seconds before the start of a dehydration operation, thereby unbraking the dehydration tub (21). When a dehydration tub lid (42) is opened, the control circuit is responsive to a lid switch (45) interlocked with the lid (42) and operates to immediately deenergize the dehydration motor (22) and then, to deenergize the operation motor (33) with a delay of one or two seconds so that the dehydration tub (21) is braked. <IMAGE>

Title: FM receivers
Inventor: ICHIKAWA TOSHIHITO
IPC: H03D1/22
Filed: 1987-09-30
Abstract: An FM multiplex broadcast receiver capable of receiving an FM broadcast signal including a data signal indicating the classification of a broadcast program, is disclosed. The receiver has a data demodulating circuit comprising a first phase-locked loop circuit 16 and a second phase-locked loop circuit 17 for producing a data demodulating clock signal in response to a demodulation output provided by the first PLL circuit. Lock detecting means 20 is provided for detecting a locked state of the second phase-locked loop circuit 17 to provide a lock detection signal. A lock range of the first phase-locked loop circuit 16 is decreased in response to the lock detection signal. This may be done by changing the time constant of a loop filter 8 or by changing the loop gain and is for preventing the synchronisation of the loop from being affected by external factors. <IMAGE>

Title: A method for improving the electrical erase characteristics of floating gate memory cells
Inventor: LAI STEFAN K C
IPC: H01L21/336
Filed: 1990-12-07
Abstract: A method for fabricating floating gate memory arrays with improved electrical erase characteristics and a reduced gate oxide defect density is described. According to the invented method, a protective polysilicon layer (11) is deposited immediately following growth of the tunnel or gate oxide (15). The polysilicon layer caps the gate oxide, protecting it from exposure to defect-causing contaminants and to insure that a uniform tunnel oxide thickness is maintained across the entire length of the channel; especially over the electron tunnelling regions. Erase speed is improved for flash EEPROM devices fabricated according to the present invention by about 5-100 times. <IMAGE>

Title: Encoding and generation of graphics images
Inventor: SOUTHEREN CRAIG RAYMOND
IPC: G06T9/00
Filed: 1991-06-17
Abstract: A graphics signal representing pixels each having a variable characteristic, such as colour or intensity, is run-length encoded as consecutive pixel runs. Each run is encoded with an associated parameter representing a linear relationship between the values of the characteristic for the pixels of the run relative to a value of the characteristic from a consecutive run, e.g. the preceding run. A generator generates the graphics signal by expanding the run-length encoded data from a memory. A linear interpolator interpolates between the values of the associated parameters to determine the value of the characteristic for each pixel in the run. <IMAGE>

Title: Double-walled tubular members and their manufacture
Inventor: BROUGHTON RONALD DAVID
IPC: B29C48/13
Filed: 1992-08-28
Abstract: A tubular member such as a plastics drain pipe is extruded in two linked elements (11,12). the outer one (11) of which is further moulded by endless belts (16) carrying formations (17) which form circumferential corrugations (14) contacting the inner element (12).
