IPC: G01N5/02
Filed: 1988-04-14
Abstract: PURPOSE:To obtain accurate equilibrium data and to shorten a determination time by stopping admitting solvent vapor after the relative vapor pressure in an airtight container is maintained within a permissible range for a constant time. CONSTITUTION:A pressure detecting means detects the pressure in the airtight container and a weight detecting means detects the weight of a sample. Then a data sampling means samples pressure and weight data obtained by the pressure detecting means and weight detecting means at a constant period.

Title: Usb controller and device loading the same
Inventor: KATAYAMA TOSHIHIKO
IPC: G08C15/06
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a universal serial bus(USB) interface for a device with which communication is surely enabled just after the cancel of bus reset even when a host immediately issues a bus reset signal by knowing the power source ON of the device. SOLUTION: Concerning a USB controller 1, the pull-up of a signal line D+ for reporting the power source ON of the device to the host can be controlled through a switching element Q1. When the power source of the device is turned on, a CPU 3 of the device performs the initialization of itself and the initialization of a USB controller 1. During this initialization, the USB controller 1 keeps the switching element Q1 in the initial OFF state and prepares a sprious power source OFF state for the host. When the USB controller 1 is completely initialized, the USB controller 1 turns on the switching element Q1 and pulls up the signal line D+. Thus, the host knows the power source ON of the device after the initialization of the USB controller 1 is completed and afterwards, the bus reset signal is issued so that communication can be started.

IPC: H04B1/69
Filed: 1989-04-11
Abstract: PURPOSE:To remove obscurity generated in measuring distances by reproducing a carrier signal of a frequency in a difference and a sum of carriers of signals spectrum diffusing to measure phases of two reproduction signals with a reference timepiece of a receiving station. CONSTITUTION:Intermediate frequency signals as L1 and L2 are multiplied directly with a multiplier [15]. A carrier signal as L2-L1 and a carrier signal as L2+L1 obtained as output of the multiplier are extracted with band pass filters [16, 17] and the signals are subjected to a digital sampling with A/D converters [18, 19] with a signal of a reference timepiece at a receiving point as reference and obtained with a data processing computer to calculate a virtual distance. Obscurity of the virtual distance is generated at each cycle of a frequency of a difference and sum between the L1 and L2 in the cases of O1(tau) and O2(tau). In other words, DELTAt1 and DELTAt2 are removed from a virtual distance measured value by the O1(tau) and O2(tau) and an ionized layer delay time from a measured value. This achieves a significant reduction in measuring time and software.
