Title: Medical monitoring apparatus
Inventor: MIDORIKAWA YOSHIKATSU
IPC: G08C25/00
Filed: 1994-11-21
Abstract: PURPOSE: To eliminate the time and labor for preparing a receiving unit beforehand by determining whether a normal reception is made or not with a receiving unit which has failed in reception when the frequency of the receiving unit which failed in reception has been changed to that of the normally operating receiving unit, and if normal reception is made, a display of 'transmitter fails' is displayed, or otherwise, 'receiver fails' is displayed. CONSTITUTION: In a processing operation, it is determined with a CPU10 whether normal reception is made or not with each receiving unit through each channel as assigned originally. If normal reception is not made, it is determined whether other normally operating receiving unit exists which receives a signal from a transmitter. If any normally operating receiving unit exists, a local oscillation frequency of a local oscillator is changed to alter the frequency in the receiving channel of the receiving unit which fails to receive so that it conducts reception through the channel corresponding to the normally operating receiving unit. Then, it is determined whether the unit is operated normally or not. If the reception is operated normally, 'transmitter fails' is displayed on a display panel 13.  If the reception is not operated normally, 'receiver fails' is displayed on the display panel 13.

Title: Mounting board inspecting system by fluorescent paint
Inventor: KIKUCHI MASUMI
IPC: H05K3/30
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To decide a defective product by printing so that fluorescent paint is concealed by an electronic component at the time of mounting the component on an electronic board of an electronic equipment, thereby judging a lack, bent or float of the component. SOLUTION: Fluorescent paint 2 is printed between an electronic board 3 and a soldering pattern 1. At the time of mounting an electronic component 4, the board is inserted into a fluorescent lamp emitting case. In this case, when it is at a normal position, the paint 2 is concealed, and not reacted with a light of the lamp, while when it is mounted by a bent, the paint 2 is reacted with the light of the lamp to be observed as lighting. Thus, a place where the component is correctly mounted is not visually observed, but only a defective position reacted with the light of the lamp may be sought. Thus, an inspection of lack, bent or float of the component is simplified, and a defect after soldering can be reduced.

Title: Transmission equipment
Inventor: GOHARA MASAO
IPC: H04L13/16
Filed: 1987-11-16
Abstract: PURPOSE:To increase the buffer effect of a data buffer at the host side of a transmission circuit by providing a data supply control section outputting once a prescribed quantity of data and controlling a transmission section or a buffer section and inputting the result to any of the buffer section. CONSTITUTION:A transmission section 1 receives a prescribed quantity of data, applies a prescribed processing and sends the result and when the data of succeeding prescribed quantity is inputted, then an input wait signal is outputted to a data supply control section 3. The control section 3 inputs a first prescribed quantity of data to the transmission section 1 at the start of transmission, and sends a 2nd prescribed quantity of data to the buffer section 2 succeedingly. Every time an input wait signal is received, the output of the buffer section 2 is inputted to the transmission section 1 and every time the data output signal from the buffer section 2 is received, the prescribed quantity of data from the control section 3 is supplied to the buffer section 2. Since the read from the buffer section 2 and the write to the buffer section 2 are applied alternately, the buffer effect absorbing the effect of delay of the data output from the host side due to the delay in the transient processing at the host side is increased.
