IPC: H01L23/50
Filed: 1984-03-30
Abstract: PURPOSE:To improve heat-dissipation characteristics while facilitating handling by making the thickness of a resin sealing section for a lead thicker than the outside of a resin in a resin seal type semiconductor device. CONSTITUTION:A stepped beltlike metallic material is press-worked or etching- worked, and the thickness of frame plates of an island section 1' and internal lead sections 2' in a lead frame is made thicker than external lead sections 3'. The occupying ratio of the metallic material in a section sealed with a resin 6 is increased, and a heat-dissipation effect and the tensile strength of leads can be improved. Since the thickness of the external lead sections 3' is thin, the leads are bent easily on mounting to a printed board, and handling property is not deteriorated.

Title: Faul detector for rotary type magnetic flaw detector
Inventor: KUDOU YASUICHI
IPC: G08C19/00
Filed: 1984-03-29
Abstract: PURPOSE:To detect a faul in a rotary section quickly by adding faul detection filters each having an input channel and a comparator to first and second time- division switches to give an alarm when a comparator output vanishes during the flaw detection. CONSTITUTION:In a first time-division switch circuit 22, a channel 22g added to the outputs of detection elements 10a-10f and integrated with a channel 23. The outputs are led to a stationary section 20 via a slip ring 11 and a brush 15 and separated into elements 24a-24g of the second time-division switch circuit 24. Then, during the detection of flaws, flaws of a material 3 to be inspected corresponding to the elements 10b and 10d appear at Eb and Ed. When the equipment is normal, an output level Eg of a filter 25g always goes higher than the voltage of a set power source 34 and further, a comparator 35 produces an output. But in case of a trouble in side a rotary section 19, the level Eg is below the output of the power source 34 and the output of the comparator 35 vanishes. Thus, any trouble in the rotary section can be detected immediately.

IPC: G06F17/30
Filed: 1987-03-19
Abstract: PURPOSE:To narrow a searching space and to increase the processing speed with a knowledge base processor by using a knowledge filter and a memory means and obtaining an answer out of a knowledge base via an arithmetic processing part and the knowledge filter with use of the horn nodes stored in the memory means. CONSTITUTION:A search tree of a knowledge base 4 is decided when a certain inquiry is received. Thus it is possible to previously choose such nodes that are possibly used in an inference process before execution of the deductive inference out of the base 4 when said inquiry is received. When the inquiry is received, a knowledge filter 1 extracts all horn nodes with which the higher and lower rank relations can be unified out of the base 4 based on the search tree of the base 4. These extracted nodes are stored in a primary memory part 5. An arithmetic processing part 6 chooses the desired nodes out of a small search space narrowed previously at the part 5 and carries on the arithmetic processing.

For one example, when the open circuit state is detected in the case that the reader 4 is not mounted on a device main body 2, 'direct transmission mode' is selected, and if the open circuit state is not detected, 'memory transmission mode' is selected. Besides, when the open circuit state is detected in the case that the reader 4 is mounted on the device main body, the operation mode is set at 'ordinary transmission mode', and when the open circuit state is not detected, it is set at 'copying mode'. Thus, the operability can be improved.

Title: Washing machine having foreign matter removing filter
Inventor: NAKAMURA FUMIO
IPC: D06F21/04
Filed: 1989-03-15
Abstract: PURPOSE:To enable high-efficient and reliable removal of a foreign matter, e.g. thread waste, by a method wherein the opening of a filter is positioned in a level higher than a normal level during standstill and slightly lower than a level up to which water is pumped along with rotational rotation of an inner drum. CONSTITUTION:During mounting and demounting of a filter 111, a filter frame body 114 is inserted between two guide pieces in a state to be guided by two guide pieces 119. In the mounting state of the filter frame body 114, the whole of the opening part of a filter body 118 is arranged in a level higher than a normal level Wn, and in a level slightly lower than the height of a level Wp up to which water is pumped along with rotation of an inner drum 31. Thus, during a washing motion and a cleansing motion, water in an outer drum 15 is pumped from the normal level Wn up to the level Wp along the outer periphery of the inner drum 31. Since the filter body 118 is opened in a level approximately equal to the normal level Wn in the outer drum 15 and thereabove, a foreign matter, e.g. thread waste and button, separated away from the laundry is reliably conveyed from the opening of the filter body 118 to the interior thereof, and the foreign matter is effectively caught by means of the filter body 118.

Abstract: PURPOSE:To execute the suitable indoor temperature control even when a temperature detecting element goes into an abnormal condition by executing the driving and controlling with a driving signal corresponding to the latest memory data stored at a memory circuit before the abnormal condition is obtained. CONSTITUTION:When a thermister 10 comes to be a shorting condition at the time of t1, a control signal, in which a rewriting prohibiting and reading can be executed, is outputted from the output side of an abnormality deciding control circuit 27 to a memory circuit 35, and therefore, the memory circuit 35 prohibits the writing of the driving data from a compressor control circuit 16 and outputs the latest memory data stored at a driving signal output circuit 36 before the thermister 10 comes to be the abnormal condition. Consequently, at the output side of the driving signal output circuit 36, the driving signal appears in which the period of an H level corresponding to the memory data is tau<1> (for example, 8min), the period of an L level is tau<2> (for example, 12min) and a repeating period is T(=tau1+tau2), and the driving signal is supplied through an always opened contact 29 of a changing-over switch 17, a moving piece 19 and a common terminal 20 to a compressor 21. Thus, a suitable indoor temperature control is executed by the driving mode corresponding to the driving signal.

Filed: 1990-03-13
Abstract: PURPOSE:To prevent artificial mis-operation by allowing a centralized management equipment to discriminate a fault notice from a transmission path and a fault of a control path and reconfigurating the transmission path automatically only when they are caused simultaneously. CONSTITUTION:A selection circuit 207 selecting a file 205 or a file 206 selects the file 206 only when a fault detection circuit 208 detects a fault notice 213 from a transmission path and a reply detection circuit 209 detects a control path fault from a control path. The information from the selection circuit 207 is stored in a file 120 in a multiplexer 302A and automatic changeover in response to the information configuration is implemented by the multiplexer 302A. Thus, the network configuration of line changeover taken in response to the content of a fault is implemented by confirming a fault of the control path managed by a central management equipment 101. Thus, the changeover at a fault is ensured and intervention of the mis-judgement by the operator is avoided.
