Title: Multi-lead type writing instrument
Inventor: SUZUKI KEIICHI
IPC: B43K24/12
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the scarce movement of a refill or the impossibility of telescopically projecting or retracting of a nib by forming a lubricant layer on the part where refills are brought into contact with each other at the time of projecting or retracting of the refill in a multi-lead type writing instrument that a plurality of the refills alternately project or retract from or into the end of a sheath. SOLUTION: A lubricant layer 9 is formed by coating from the vicinity of a tip press injecting part at the end of a pipe to about an intermediate part with silicone oil. Accordingly, even if refills are brought into contact with each other, frictional resistance is reduced by the lubricant, and an actuator is scarcely failed to be operated. When the outer diameters of the refills are multi-step shape, the layer 9 is formed even on the step, and hence even if the refills are brought into contact with each other, the frictional resistance is reduced by the lubricating action, and scarcely entangled. The lubricant may be, in addition to the silicone oil, silicone grease of mixture of silicon oil and sodium stearate, or machine oil such as olefin polymer oil, or diester oil.

IPC: H04L12/56
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a simple and fast real-time device for processing a queue in a network queue server. SOLUTION: The queue server arranges a queue 10 in a usable memory space. A true head pointer 60 indicates the head of the queue 10 and this pointer 60 is stored in a true head register 70. When the queue server starts the processing of the queue and a false pointer 80 searches and finds a short packet 40 within the queue 10, the false pointer 80 stops moving within the queue 10. Concerning each processing cycle concerning the queue 10, the processing counter 120 is increased. When the processing of long packets 20, 30 and 50 is not completed when the counter 120 counts a threshold value, the position of the long packet is stored in a register within a system. After then, the processing of the short packet 40 is completed and then the processing of the long packets is started again from the stopping position. When the processing of the long packets are completed.  A next packet within the queue 10 is processed.

Title: Selective call communication system
Inventor: SUZUKI YUUJI
IPC: H04W4/00
Filed: 1984-02-29
Abstract: PURPOSE:To attain sure synchronism even if the signal speed of a call and a synchronism word is different by inserting a preamble signal from which (n+1)- time or over polarity change is obtained including a bit synchronizing signal of the synchronism word when the call word just before the synchronism word is an idle word. CONSTITUTION:The call word placed just before the synchronizing word is formed forcibly into an idle word at each several minutes among words transmitted repetitively from the transmission side, the preamble signal is inserted to the idle word and the result is transmitted. The preamble signal consists of a repetitive signal of ''00110011...'' having a bit period of 2.5msec. Thus, the preamble signal is formed apparently into the same constitution as that of the bit synchronism signal having a period of 5msec. On the other hand, a receiver supervises the leading of the reception code at the same time when power is applied, and if the timing of leading satisfies the condition of 5msecXK+ or - 0.625msec to the preceding lead timing, the synchronism is discriminated instantly to synchronize in case the signal speed of the call word and the synchronism word is different.

Abstract: PURPOSE:To obtain a high tensile strength under a normal and high temperature ambient and prevent generation of deformed loop by providing a fine wire of alloy with cerium group rare earth element, Ge, Be, Ca, Au and essential impurity mixed in the specified rate. CONSTITUTION:A cerium group rare earth element is effective for improving tensile strength under a high temperature but if amount of content is under 3/ 10,000%, such tensile strength cannot be acquired and if it exceeds 1/100%, such element shows in turn brittleness. Ge, Be, Ca raise a softening temperature of a fine wire in coexistence with a cerium group rare earth element, suppressing generation of brittleness and deformed loop and also raising a tensile strength under a normal and high temperature. If content is under 1/10,000%, such effect cannot be obtained but it exceeds 6/1,000%, the element shows some  brittleness. Therefore, the fine wire of gold alloy is formed with 0.0003-0.01wt% cerium group rare earth element, 0.0001-0.006wt% Be, Ge, Ca and Au and essential impurity as the remainders.

Title: Metal halide lamp
Inventor: IKE YUUJIROU
IPC: H01J61/52
Filed: 1979-03-30
Abstract: PURPOSE:To improve the emission of electrons and facilitate start at the circumference of a glow tube bulb by forming a heat insulating film over the range from the end of a metal foil conductor in the sealing section facing discharge space to the end in the bulb. CONSTITUTION:When the lamp lights, heat dissipation is checked by heat insulating films 11 and 11 which are coated on the end of a bulb 1 and the temperature rises at the end of the bulb 1. This improves emission efficiency. When the lamp lights off, the heat insulating layers 11 and 11 delay the temperature fall of the end in the bulb 1. This permits a great amount of metal halide gas to quickly adhere to the wall surface in the bulb which is fast in temperature fall and the quantity of adherence to main electrodes 3a and 3b and an auxiliary electrode 8 to be reduced. As a result, the work function of the electrode is reduced. Start is facilitated and starting voltage can be reduced.
