Patent JP-H05203404-A (JP)
Title: Positioning device
Inventor: YOKOYAMA KAZUO
IPC: G12B5/00
Filed: 1992-01-23
Abstract: PURPOSE:To stabilize the scanning operation of a probe head by bringing the housing of the probe head into contact with a contact plane through point- contact legs while urging the housing through a leaf spring. CONSTITUTION:Three point-contact sections are formed on the bottom of the leg section of the housing 10 of a probe head 12 by fitting three steel balls 11 to the bottom. In addition, the housing 10 is connected to a fixed table 36 which is the enclosure of the title positioning device by means of a leaf spring 13 arranged in parallel to a contact plane and the spring 13 is fixed to the table 30 with screws 17. When the relative position between a sample 4 and the probe head 13 is controlled by the three-point contact in such way, three degrees of freedom are ensured in the X-and Y-directions in the plane of the sample 4 and the revolving motion around Z-axis and the remaining motions are constrained. By using the spring 13 as means for constraining the remaining degrees of freedom, all of the degrees of freedom of the head 12 can be constrained without estranging the stable three-point contact. The head 12 can be set at a high resonance frequency by utilizing the properties of the spring 13 and, as a result, not only a high vibration-proofing effect can be obtained, but also the scanning operation of the head 12 can be stabilized.

Title: Log information collecting method and communication processing system using the collecting method
Inventor: NISHIDA SHINICHIRO
IPC: G06F11/34
Filed: 1994-02-01
Abstract: PURPOSE:To provide a log information collecting method which can take out the log information on the details of the abnormality processing in a reference/ analysis state. CONSTITUTION:The log information on the abnormality processing that stops the collection of the log information is previously registered for each processing. Then it is decided whether the collected log information is equal to the log information on the abnormality processing registered previously (S101). If decided so, a log information stop flag is turned on (S102) so that the collection of the log information is stopped together with the collection of the log information on other processing related to the processing that stopped the collection of the log information (S103). When the collection is stopped for the log information on the relevant processing, a series of log information are saved to a prescribed storage area (S105).

Title: Phase locked loop
Inventor: HOGEBOOM JOHN GORDON
IPC: H03L7/113
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To provide the phase locked loop(PLL) with small jitter and power consumption that is operated even with an input signal of a non-periodic structure such as data. SOLUTION: The PLL is provided with a voltage controlled oscillator(VCO) 118, charge pumps 120, 130, a phase detector 114 and a frequency detector 128. The phase detector 114 detects a phase difference between an input signal and a VCO signal. A frequency difference between the input signal and the reference signal is detected by the frequency detector 128 independent of the phase detector 114. In a process to attain phase synchronization, the phase detector 114 and the frequency detector 128 are operated simultaneously. When the input signal is in existence, the VCO signal is phase-locked to the input signal. When no input signal is in existence, the VCO 118 is frequencylocked to a large number of reference signals to keep a frequency close to a desired bit speed. Thus, in the case that an input signal is received successively for a period without the input signal, the PLL assists considerably quick phase locking with reliability by avoiding extreme reaction of the system.

IPC: H04N5/52
Filed: 1992-01-24
Abstract: PURPOSE:To arrange unarranged demodulation video signal levels caused by a difference of a frequency shift (modulation) from each satellite to the same level in a receiver able to receive transmission radio waves from both a broadcast satellite (BS) and a communication satellite(CS). CONSTITUTION:An amplifier circuit 2 whose amplification factor has been constant in a conventional method is revised to be an amplification factor variable type amplifier circuit. Which satellite the user selects is made clear by a satellite selection section 47 and a level correction quantity is clarified by a frequency shift decided for each satellite. Thus, an amplification factor control section 3 changes the amplification factor of the amplifier circuit 2 for each satellite by an amplification factor control signal 4 generated corresponding to the selected satellite and outputs a video signal of a prescribed level independently of each satellite to a terminal 51. As to how to arrange unarranged video signal levels from a demodulation section 45 to the same level, there are a method matching a video level of other satellite with a reference level which is a video level of one satellite and a method setting the levels to entirely other level.

Title: Zinc alkaline battery
Inventor: MIURA AKIRA
IPC: H01M4/42
Filed: 1987-01-20
Abstract: PURPOSE:To increase the corrosion resistance of a zinc alloy used in a negative electrode and to decrease the amalgamation rate of negative zinc by utilizing a synergetic effect produced by the combination of added elements. CONSTITUTION:A zinc alloy containing 0.01-0.5 wt.% thallium, 0.01-0.5 wt.% bismuth and/or tellurium, and 0.01-O.2 wt.% aluminum is used as active material. Thallium has a high effect on increasing hydrogen overvoltage, is well alloyed with mercury at room temperature, and increases the hydrogen overvoltage on the surface of zinc. Bismuth retards the diffusion of mercury from the surface of amalgamated zinc to the inside through grain boundaries and retains high mercury concentration on the surface of zinc. Addition of aluminum increases the corrosion resistance of zinc. Therefore, a zinc alkaline battery whose amalgamation rate is low but practicality is high can be obtained.

Filed: 1995-01-27
Abstract: PURPOSE: To allow the system to multiplex and integrally manage multi-cast communication and 1:1 communication through one communication channel by sending data of multi-cast transmission to the channel at a prescribed period and sending data of 1:1 transmission at each gap of the periodic transmission of the multi-cast communication. CONSTITUTION: A multi-cast(MC) transmission request is issued after designating transmission data, a transmission destination MC group(MCG) and a transmission level. The system receiving this request connects transmission data to a queue of a transmission level designated by a request destination MCG. A period start transmission routine is started when not being started. When this routine is started, An MCG# and a transmission level having been sent previously are received. When transmission wait data are in existence in a succeeding queue, a transmission channel of a transmission MC pattern is decided. When the transmission buffer is not fully occupied, the transmission data are set to a transmission channel buffer. The transmission processing is conducted to all channels registered in the MC pattern in this way and the MCG# and the transmission level sent this time are saved.  Finally when MC transmission queue transmission wait data are in existence, a timer to start this routine period is set.

Abstract: PURPOSE:To prevent the double feed of sheets due to excessive insertion of the sheet or the defective feed of the sheets by protruding a tip blocking member to the feed belt side by means of a sheet absent signal from a sheet detecting sensor and moving aside the tip blocking member by means of a sheet present signal. CONSTITUTION:A sheet feeding device is provided with a tip regulating member 9 to regulate and match the tip of a sheet S and a sheet detecting means 5 to detect the presence of the sheets S on a sheet loading means 3. In the sheet feeding device, when the absence of the sheet is detected by the sheet detecting means 5, a tip blocking member 7 with which the tip regulating member 9 is formed is moved to a position below a sheet loading lowermost surface. By eliminating a gap between the tip regulating member 9 and the sheet loading lowermost surface, the sheet tips are trued and reliable loading is effected. When the presence of the sheets is detected by the sheet detecting means 5, the tip blocking member 7 is moved upward so as to part from the sheet loading lowermost surface by a specified distance, and the sheet S is brought into a state to be fed from the sheet loading means 3. This constitution prevents the occurrence of a trouble, e.g. the double feed or the defective feed of the sheets S.
