Title: Semiconductor device
Inventor: SUZUKI HIDEO
IPC: H01L29/732
Filed: 1990-06-30
Abstract: PURPOSE:To spread a depletion layer, which is generated on the face of the junction between a semiconductor substrate and a second conductivity type resistance region, to reduce the junction capacitance in the resistance region and to reduce the parasitic capacitance between a collector and an emitter by a method wherein a second conductivity type second resistance region having an impurity concentration lower than that of the second conductivity type resistance region is formed under the lower part of the second conductivity type resistance region and on the periphery of the second conductivity type resistance region. CONSTITUTION:An N-type semiconductor substrate 1 having a resistivity of 0.5 to 2.5OMEGA.cm is used as a collector region, a P-type base region 2 having a sheet resistivity of 1 kOMEGA/square or thereabouts is formed in this substrate 1, P- base ring regions 3 are formed on the outer periphery of the region 2 and an N<+> emitter region 4 and a P<+> base contact region 5 are formed in the region 2. On the other hand, a P<+> resistance region 6 having a comparatively high impurity concentration is formed in the substrate 1 as an emitter ballasting resistor and a P- second resistance region 11 having an impurity concentration lower than that of the region 6 is formed on the outer periphery of the region 6 and under the lower part of the region 6 by an ion implantation of boron and the drive-in process of the boron before the region 6 is formed.

Title: Card lock system
Inventor: OKADA NORIKAZU
IPC: E05B35/00
Filed: 1994-07-04
Abstract: PURPOSE:To eliminate a burden on a movable member because the movable member is slid against the elastic force of a coil spring, and to machine a tumbler and a key piece easily by pivotally attaching the tumbler while using a pivotal base end as a pivotal fulcrum and reducing the width of the vertical movement of the pushing section of the tumbler. CONSTITUTION:When a key piece 9 is inserted from an opening, the pushing projecting sections 5b of tumblers 5 projected into an air gap section 2 are pushed by the front end of the key piece 9. When the key piece 9 is further inserted, the pushing projecting sections 5b are fitted into recessed grooves 11a formed to key chips 11. The recessed grooves 11a are formed in arbitrary depth set to each key chip 11 before the fitting into the recessed grooves 11a. Each pushing projecting section 5b is brought to an inserted state into each recessed groove 11a. Movable members 6 are slid vertically in slots 3 by the pivotal movement of each tumbler 5. Accordingly, a large number of card lock systems can be combined only by changing the built-in places of the tumblers and the depth of grooves, into which the key chips coinciding with the built-in places are buried.

Title: Surface acoustic wave resonator
Inventor: ETSUNO MASAYOSHI
IPC: H03H9/25
Filed: 1990-06-30
Abstract: PURPOSE:To prevent spurious resonation due to the influence of a neighboring surface acoustic wave resonator by arranging an accessory pattern which distorts the wave front of a leaked surface acoustic wave at an area outside a grating reflector. CONSTITUTION:The accessory pattern 20 consisting of the same material(Al, etc.,) as that of the IDT 13 or the grating reflector 14 and which distorts the wave front of a surface acoustic wave(SAW) leaked from the grating reflector 14 to the outside is provided in the area outside the grating reflector 14 in a direction to propagate the SAW excited by an IDT 13. Deviation occurs between the upper and lower sides in the wave front of the SAW while the SAW leaking from the grating reflector 14 to the neighboring surface acoustic wave resonator 12 on the left side arrives at the surface acoustic wave resonator 12. When the SAW is reflected on the grating reflector 14 of a neighboring pattern and is propagated again on a propagation path, the deviation occurs further between the upper and lower sides. In such a way, the resonation between the neighboring patterns can be suppressed.

IPC: G06F12/00
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To prevent te body cut of a picture, to simplify the design of a FIFO memory and to reduce manufacture cost. SOLUTION: A comparator 6 compares an input pointer showing a write position into a memory part 2 with an output pointer showing a read position from the memory part 2, and outputs a result signal showing the compared result.

Then, it masks the write permission signal and inhibits a write operation when the input pointer and the output pointer become equal by the result signal. An output control part 5 controls the reading of picture data from the memory part 2 by the output pointer and the read permission signal. An interruption control part 8 generates an interruption signal showing that the input pointer and the output pointer become equal when it recognizes it by the result signal.
