Title: Surface acoustic wave device, communication system using it and its receiver
Inventor: YOKOTA AKANE
IPC: H04B1/707
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To enhance the S/N with a simple configuration by using a package mounted on a board so as to isolate an input side circuit and an output side circuit on the same board and to eliminate the need for a shield frame thereby improving the isolation between the input and the output. SOLUTION: Input side circuits 10a, 10b and an output side circuit 11 mounted on a board 12 are isolated by a conductive package 9 incorporating a surface acoustic wave element 7. A convolution signal of a surface acoustic wave generated from the surface acoustic wave element 7 is extracted from input and output terminals to the outside and part of the input electric signal is emitted in the air when it propagates to the input side circuits 10a, 10b. However, the package 9 prevents the emitted radio wave from reaching the output side circuit 11 to suppress electromagnetic coupling between the input and the output thereby avoiding crosstalk of the spurious wave. Thus, a shield frame to enhance the isolation between the input and the output of the surface acoustic wave device is not required to obtain the electromagnetic shield effect.

Title: Semiconductor photodetector
Inventor: KOBAYASHI MASAHIRO
IPC: H01L31/107
Filed: 1984-05-31
Abstract: PURPOSE:To dispose the position of a p-n junction of both semiconductor layers substantially on the same surface by providing high and low difference between the surface of the layer for foring an avalanche amplifier and the surface of the layer for forming a guard ring. CONSTITUTION:A high and low difference is formed between the surface of an avalanche amplifying layer 3 and the surface of a semiconductor layer 4 for a guard ring to form a step 9. According to this construction, a p-n junction between the layer 3 for foring the avalanche amplifier AB and the layer 4 for forming the guard ring GR is disposed substantially on the same surface. In this case, an n type InP is used for the layer 3, an n<-> type InP is used for the layer 4, the type utilizing the difference of carrier density is adopted, but this can obtain the same effect even if employing the narrow and wide forbidden band widths with an n type InP for the layer 3 and an n type AlInAs for the layer 4. With this structure, effective guard ring effect can be obtained to increase the degree of freedoms in designing a semiconductor photodetector of this type.

Title: Ink-recovering device for ink jet printer
Inventor: YAMAZAKI HIROSHI
IPC: B41J2/185
Filed: 1980-08-09
Abstract: PURPOSE:To smoothen the recovery of an ink and movements of a printing head by a method wherein a short pipe for an ink-recovering device being moved as one body with the printing head is connected to a liquid-receiving part at a predetermined position only, without using any long ink-recovering pipes. CONSTITUTION:The ink-recovering pipe 33 is connected to the liquid-receiving part 40, only when the ink-recovering device 7 moved as one body with the head is returned to its home position. For instance, a nozzle part 36 opened and closed by a valve 35 having a magnet of the same polarity with that of the liquid-receiving part 40 is provided at the tip of the ink-recovering pipe 33, and the valve 35 being normally closed is opened by a magnetic repulsive force at the time of inserting the tip of the pipe 33, resulting in that the ink is jetted energetically. In addition, a pushing rod 37 rotates a lever 38 to expand an expansion bellows 43 so that the ink is sucked in through a suction valve 42 by a negative pressure. Accordingly, since no long pipes of large diameter are used, such troubles as lowering in stability  of a carriage and dripping of a liquid can be prevented.
