Title: Indicating instrument
Inventor: NOGUCHI MASANORI
IPC: G01D13/22
Filed: 1990-03-31
Abstract: PURPOSE:To enable prevention of deflection of a pointer due to the collision of the pointer with a pointer stopper by providing the stopper at a minus position from a zero indicating pointer position when an input signal from an object of measurement has a value of the lower limit of measurement or below. CONSTITUTION:Receiving a digital value input of the lower limit of measurement or below, a ROM element 21 stores data on the amount of electrification of X and Y coils so that a pointer be driven to an indication angle being plus from an original zero point indication angle. An indicating element 3 is provided with a display of zero point indication at an indicating position of the pointer driven by a driving output when the value is the lower limit of measurement or below, and a stopper is provided on the minus side from the position of this zero point indication display. Since the data of the ROM element 21 are set so that the pointer indicates the zero point indication position when the value of an input signal is the lower limit of measurement or below, the pointer indicates a prescribed zero point. When a vehicle speed decreases rapidly, moreover, the pointer reaches the zero point indication position smoothly even if the operation of the pointer delays, since the operation of the pointer at the lower limit of measurement or below is made so that the pointer indicates the zero point indication position on a dial plate of an instrument, and thus no collision with the stopper takes place.

Title: Incoming state discrimination method for communication line
Inventor: SHIMAOKA YUKINORI
IPC: H04Q1/446
Filed: 1989-04-05
Abstract: PURPOSE:To discriminate an incoming state without using polarity inversion by measuring an input signal from a line, detecting the frequency distribution, consecutive time and repetition and classifying the signal into any of a dial tone, a busy tone and a ringback tone. CONSTITUTION:The detection of an input signal is started via a line from a receiver. A timer set to 1.2sec is started and the count of sampling cycle number and the measurement of the period are started. When the input signal is lost before the time of 1.2sec expires and the time of 1.2sec elapses, the measurement of period is stopped, When the consecutive time is 0.15sec or below and number of sampling cycles is 20 or below, it is discriminated to be a pulse noise. Then whether or not a line specific signal in a single tone is discriminated and the signal is not the specific signal, it is decided to be a consecutive noise. In the case of the specific signal, whether the signal is a dial tone, a ringback tone, a busy tone or any other is decided.

Title: Sequence controller
Inventor: EGAMI NORITAKA
IPC: G05B19/05
Filed: 1989-04-07
Abstract: PURPOSE:To decrease the total number of steps and to reduce the memory size of a fixed data table by using a step resetting means to shift the operation to a stored step or its following one when the prescribed branch conditions are satisfied. CONSTITUTION:A step number storage part (return No 13) stores the original step No when a step is shifted into a sequence table. Then a step resetting means shifts the operation to a stored step or its preceding one when the prescribed branch conditions are satisfied. The value stored in a step No 12 is saved into the place of a return No 13 and then the step No 12 is updated when a monitor timer UP flag of a branch condition No is kept at '1' and in a state except OFFH. Furthermore, the value stored in the place of the return No 13 is shifted to the step No 12 when the branch condition No is kept in an OFFH state. As a result, the number of abnormal state processing steps is decreased together with reduction of the memory capacity.

The computer, for example, utilizes the tank model method that is the outflow analysis method of hydrology for calculating the rainfall amount from the upper, middle, and lower layers or the like of cloud according to a graph with time and rainfall amount as an abscissa and an ordinate, respectively. The obtained characteristics are compared with relation data D2 between a past raindrop and the cloud, and the state of the cloud is grasped. The state of the cloud is compared with relation data D3 between the past cloud and the rainfall amount, thus drawing the hyetgraph of the rainfall amount, and hence estimating the succeeding rainfall amount.

Abstract: PROBLEM TO BE SOLVED: To ensure an easy-to-handle and accurate measurement in using a sample lighting source by focusing an image at a specified position of an optical system in a spectrophotometer on a specified position of a sample measurement base. SOLUTION: A relay lens 35 focuses an image at a diffraction grating of a spectrophotometer 1 or at a sample position on a surface of a diaphragm 31.
