Title: Electronic bulletin board device
Inventor: IWAMI TADASHI
IPC: H04L12/58
Filed: 1989-08-09
Abstract: PURPOSE:To eliminate the need for the retrieval of an electronic bulletin board by the user by automatically informing that a new message is written onto the electronic bulletin board. CONSTITUTION:When a message is newly written in a message bulletin board BBx, a message notice section 5 reads storage information of a user name list Lx corresponding to the board BBx, the user name registered to have a notice is discriminated and the information representing the presence of the message is sent from the message notice section 5 to the terminal equipment of the user name discriminated therefrom. Thus, the presence of new write of a message to the terminal equipment of each user registered as the presence of notice is informed automatically in such a way, then the display based on the notice information is issued onto a display screen of, e.g. the terminal equipment. Thus, each user confirms the presence of write of a new message.

Filed: 1984-09-29
Abstract: PURPOSE:To enable reduction of pulsation of discharge oil and the occurrence of a fluctuation in a pressure, by a method wherein a space, formed between contact parts of inner and outer rotors, is communicated with a groove formed in and open to the end surface of the inner rotor between tooth grooves having ends adjoining to each other. CONSTITUTION:A groove 3, circumferentially extended, is formed in the tooth foot part of the end surface of an outer rotor 2, and the ends of the groove 3 are respectively open to tooth grooves 2a located on both sides of the groove 3. Thus, pressure oil, present in a space S formed between contact parts of teeth 1a and 2A of the inner and outer rotors 1 and 2, is moved in other space S through the groove 3. In which case, the sectional area of the groove 3 is decided in consideration of a reduction in pulsation and a fluctuation in a pressure and lowering of pump efficiency. This constitution enables relieve of momentary high and low pressures, prevents the occurrence of pulsation and a fluctuation in a pressure of discharge oil, and permits sharp decrease of the generation of noise and vibration.

Filed: 1987-08-19
Abstract: PURPOSE:To smoothly execute reproducing, FF and REW operation by setting up the average roughness of the center line of a smooth sheet on the upper half side to a value smaller than that of a smooth sheet on the lower half side and reducing the frictional coefficient of the sheets. CONSTITUTION:The average roughness (Ra1) of the center line of the transparent smooth sheet 14 on the upper half 5a side and the average roughness (Ra2) of the center line of the smooth sheet 15 on the lower half 5b side are set up to Ra1<Ra2. Since the frictional coefficient of the sheet 15 on the lower half side is smaller than that of the sheet 14 on the upper half side, torque at the time of traveling the tape 2 having comparatively small tensile force and capable of easily traveling while being stuck to the surface of the sheet 15 can be sharply reduced. Consequently, reproducing, FF and Rew operation or the like can be smoothly executed. The average roughness of the center line is preferably set up to Ra1<=0.15mum and Ra2>=0.2mum (Ra1/Ra2<=0.75) and Ra1<=0.06mum and Ra2>=1.0mum (Ra1/Ra2<=0.06) are more preferable.
