Title: Ink attaching mechanism for wire type dot printer head
Inventor: GOMI YOSHIFUMI
IPC: B41J2/265
Filed: 1980-06-17
Abstract: PURPOSE:To supply stably a proper amount of ink to a printing end surface even in time of high speed operation by a method wherein behind a wire guide near a printing end surface of a wire there is provided on ink passage, from which ink is supplied by means of capillarity. CONSTITUTION:The ink supplied from an ink supply pipe 58 strikes against the wall surface 66 of an ink supply hole 59 and an ink passage 55 and then part of it flows into an ink passage 50 which is constituted so that it may cross ink bypasses 61, 62 and a wire 51, and is exhausted through an ink exhaust 60. At this time, the ink does not flow directly into the ink passage 50 but it is saturated by means of capillary attraction. Therefore, the dynamic pressure of ink by a pump and the like is hard to transmit and a constant quantity of ink is always held stably. Further, the ink in the passage 50 is supplied to the printing end surface of the wire by means of capillary action of the clearance 54 between a wire guide 52 and a guide hole 51 and flows into an ink adjusting-and-collecting groove 69. The groove 69 serves to keep a suitable amount of ink on a printing end surface of a wire.

Title: Crystalline semiconductor film and formation thereof
Inventor: YONEHARA TAKAO
IPC: H01L21/324
Filed: 1989-03-31
Abstract: PURPOSE:To achieve crystal growth with solid phase by providing an additional region, where a substance whose melting point is lower than that of a semiconductor is added, on the film of an amorphous semiconductor film and then performing heat treatment at a temperature below the melting point of the semiconductor. CONSTITUTION:Sn is added to a specified part locally within an amorphous Si 2 which is formed on an SiO2 substrate 1 and then an Sn-containing amorphous Si 3 is crystallized to inducing occurrence of nucleus by performing heat treatment at a temperature where the amorphous Si containing Sn is crystallized. Since the crystallization temperature at other amorphous Si region is much higher than that of the impurities addition region, no nucleus occurs within the inside. Furthermore, heat treatment is allowed to continue, a nucleus whose position is controlled continues to grow and crystallization advances into the amorphous Si region. After that, when heat treatment further continues, a grain boundary 5 occurs nearly at the middle point where nuclei are generated due to collision of crystal grains 4, 4' whose position is controlled. Thus, the grain boundary position of a single crystal semiconductor film or single crystal is controlled, thus forming the crystalline semiconductor film.

Title: Body detector
Inventor: AOKI TAKESHI
IPC: G01F23/22
Filed: 1979-06-27
Abstract: PURPOSE: To attain stable body detection by detecting whether one terminal of a vibrating piece is brought into contact with a body from the variation of an electric current showing the existence of vibration.  
     CONSTITUTION: A flow of an exciting current through driving coil 4 vibrates vibrating piece 1. Once a body comes in contact with vibrating piece 1, the body stops vibrating piece 1 from vibrating, so that the vibration will be caused to stop or decrease in vibration frequency. As a result, the fluctuations of the density of magnetic flux crossing detection coil 5 are eliminated and driving circuit 6 outputs a constant voltage, thereby keeping on flowing the exciting current through driving coil 4. Current detector 7 detects the constant current at that time and outputs control signal SA showing that the body resides.
