Title: Lan interface selection processing method for lan terminal equipment
IPC: H04L69/14
Filed: 1992-04-01
Abstract: PURPOSE:To eliminate working load and to construct a LAN system having high efficiency by deciding a LAN interface connected normally to a cable and then deciding the use of the LAN interface. CONSTITUTION:LAN interfaces IF 6a-6c are provided to secure the connection of the LAN 2a-2c respectively. A LAN terminal equipment 10 automatically selects the desired one of those interfaces IF 6a-6c of different rules. In this case, the IF 6c of a 10BaseT rule for example, is selected and a link signal is received. Thus, the use of the IF 6c is decided. Meanwhile the IF 6b of a 10Base5 rule is selected if the link signal is not received. Then, the IF 6b transmits a packet which is addressed to its own LAN terminal equipment. Thus, the use of the IF 6b is decided if an SQE signal is received via the IF 6b. If the reception of data is confirmed, the use of the IF 6b is decided after decision of the normal connection between the IF 6b and a transceiver 7b even though the function of an SQ test sequence is turned off and on SQ signal is received.

Title: Method and apparatus for automatic vibrating inspection
Inventor: HOSOKAWA RIYUUJI
IPC: G01N21/59
Filed: 1978-06-30
Abstract: PURPOSE:To perform the vibration inspection for liquid with high accuracy by a simple operation, by using a pair of light emitting and photo detecting elements and detecting the time aging of the test piece in the tube based on the amount of light reception. CONSTITUTION:The test piece tube 4 containing a suitable amount of liquid test piece 8 is placed on the upper part of the vibrating stand 3 and it is supported with the fixture 10 from the upper part. When electric power is applied to the vibrating stand drive unit 1, since the major shaft 2 reciprocates left and right in a given period, the test piece tube 4 repeats the vibrating operation. When light is projected from the light emitting element 5 during this vibration, the light transmits the test piece 8 in the test piece tube 4 and it is received in the photo detector 6. But, when the test piece 8 is changed with the vibrating operation, the light is absorbed. Since the amount of transmitted light is changed for the share, the output from the element 6 is also changed. Accordingly, the vibrating inspection can be made with high accuracy by displaying the state of change on the display unit 7.

Title: Magnetic ink transfer medium and printing method by said medium
Inventor: FUKUSHIMA HITOSHI
IPC: B41J31/00
Filed: 1988-03-31
Abstract: PURPOSE:To increase thermal efficiency at the time of transfer and prevent paper to be transferred from being soiled by ink, i.e. ink sticking to the part requiring no printing by using a magnetic ink transfer medium of magnetic ink at less than 20dyn/cm of surface tension when the ink is thermally melted and causing the magnetic ink to stick to a medium to be transferred with the application of magnetic force and heat to the magnetic ink transfer medium. CONSTITUTION:The surface tension of magnetic ink is adjusted by adding a surfactant as an ink component. The surface tension of the magnetic ink at the time of thermal melting is set to less than 20dyn/cm. The surface tension of the adjusted magnetic ink at the time of thermal melting varies according to measurement temperature; and the higher temperature, the less surface tension. Consequently, the surface tension should be measured at 120 deg.C (test value). When the surface tension of this heat-melting magnetic ink exceeds 20dyn/cm, the size of transfer dots of magnetic ink becomes irregular (poor dot reproducibility) and subsequently, the printing quality becomes inferior and the transfer efficiency decreases. Consequently, the ink transfer medium easily generates poor transfer results as a whole.

Abstract: PROBLEM TO BE SOLVED: To realize a recorder low in cost and high in productivity by forming an image having stable density without being influenced by temperature and humidity as an electrophotographic recorder for forming an electrostatic latent image by radiating image light to an electrified photoreceptor. SOLUTION: By combining the photoreceptor whose potential attenuation factor by exposure has positive characteristic to the temperature and the humidity with a electrifying device whose initial electrification potential has the positive characteristic to the temperature and the humidity, an area where the light discharge characteristic curves of the photoreceptor at a high temperature and high humidity and low temperature and low humidity cross is given. The exposure at a quantization level 1 in a multilevel error diffusion method is set to this cross area. A developing device having the characteristic that developing weight is saturated in an area where developing contrast potential is comparatively low is used as the developing device, and the exposure at the quantization level 2 is set to the saturation area.  Thus, the stable image having no density fluctuation to environmental change is obtained.
