Title: Lead frame for resin-encapsulated semiconductor device
Inventor: NAKAZAWA EIICHI
IPC: H01L21/56
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a lead frame for resin-encapsulated semiconductor device having a structure in which encapsulating resin remaining in a gate runner part after the completion of a resin encapsulation process, is removed easily. SOLUTION: A lead frame is so constituted that an Ni layer, a Pd layer, and an Au layer are formed on Cu material constituting its frame. The lead frame comprises a die pad 1, suspending leads 2, inner leads 3, tie bars 4, outer leads 5, and a frame 6. The gate runner part 7 has no Au layer. In this part, the Pd layer whose adhesion to encapsulating resin s poor is exposed, so that the encapsulation resin which remains in the gate runner 7 can be easily removed only by punching with a weak force from the back of the pilot holes 8, after completion of resin encapsulation process. Therefore, the deformation of the lead frame can be prevented reliably without adding any other member to it.

Title: Electric machine relay
Inventor: SAFUA KIRUMA
IPC: H01H37/32
Filed: 1989-06-30
Abstract: PURPOSE: To simultaneously operate a large number of contacts by applying control electric current to an operational member made of a material having a shape memory property. CONSTITUTION: A spiral operational element 10 made of a shape memory alloy is kept in an extended state from the shape set at the manufacturing time by force of a compression spring 17. When control electric current is applied to the element 10, the element is heated and turned back to the original cntracted state. Thereby resisting the force of the return spring 17, a piston 21 moves toward the stand 27. Consequently, the control member 9 is accompanied with a contact spring 14, separates a contact couple 2, and brings a contact 4 into contact with a contact 3. The opening and closing state is retained until the shape memory property of the element 10 is weakened by shutting the control current and an initial set state is again restored by the spring 17. As a result, a large number of contacts can be simultaneously operated.

Title: Solenoid pump
Inventor: MIZUNO AKIRA
IPC: F23K5/14
Filed: 1979-12-22
Abstract: PURPOSE: To simplify the discharge side piping of a solenoid pump by communicating an air vent with the upstream end on an of-off valve provided in the pump discharge path and providing an air vent mechanism for effecting air vent by opening the on-off valve when the upstream pressure becomes lower than a predetermined value.  
     CONSTITUTION: Liquid fuel is discharged by pump action from a pump chamber 2 through a discharge valve 5 to a discharge port 6. If air is mixed in the liquid fuel, the pressure at the discharge port 6 is low, and an on-off valve 27 remains closed. Thus, air is discharged through an air vent passage 30 to the top of the interior of a fuel tank 4. When air on the upstream side of the on-off valve 27 in the discharge port 6 is almost completely purged, the pressure in this part is now above a predetermined pressure. Thus, the on-off valve 27 is moved to the left to open the discharge port 6 and close the air vent passage 30. With the air vent mechanism assembled in the solenoid pump in this way, it is possible to reduce the size of a liquid fuel combustion apparatus having an solenoid pump.

Title: Phase locked loop circuit
Inventor: AOKI IKUO
IPC: H03L7/18
Filed: 1988-07-06
Abstract: PURPOSE:To realize a phase locked loop circuit with higher resolution more than that of an integral number of multiple of a reference frequency without lowering a reference frequency by controlling the change quantity per unit time of a phase difference signal. CONSTITUTION:An A/D converter 5 and control circuit 6 constitute a differentiating circuit 7 applying differentiation equivalent to an output of a phase difference signal 4. When an output frequency f0 of a voltage controlled oscillator(VCO) 1 is not an integral number of multiple of the reference signal frequency fr, an output of a phase comparator 4 is a sawtooth waveform. Then phase lock is applied by the differentiating circuit 7 so as to apply feedback to the VCO 1 in a way that a differentiating value of the sawtooth waveform is made constant, the A/D converter 5 samples the sawtooth waveform at a proper time interval in the differentiating circuit 7 to apply A/D conversion and the control circuit 6 outputs a control voltage to the VCO 1 so that a difference of a digital output for each sample is made constant. Thus, the phase locked loop circuit with higher resolution more than an integral number of multiple of the reference frequency and with fast response is realized with simple constitution without lowering the reference frequency.

Title: Picture filtering device
Inventor: KANEKO YOSHIKAZU
IPC: H04N1/40
Filed: 1992-06-03
Abstract: PURPOSE:To reduce the blocking noise or the like due to a JPEG algorithm or the like without damaging high-band components of a picture. CONSTITUTION:A decoder 30 decodes encoded picture data 204 encoded in accordance with the JPEG algorithm. A load data arithmetic means 401 adds the results obtained by multiplying coefficient data Y1 to Y64 (picture data expressed by two-dimensional spatial frequencies) outputted from a Huffman decoder 303 by weighting data M1 to W64 and calculates load data. A filtering means 403 selects a filter matrix which has a window size corresponding to the value of load data. When a fine picture is included in the picture block, the filter matrix having a small window size is selected because the value of load data is large. Thus, the filtering means 403 reduces the blocking noise due to quantization error or the like without damaging the fine pattern of the picture.
