Title: Thermal head
Inventor: TOZAWA KAZUO
IPC: B41J2/345
Filed: 1990-03-13
Abstract: PURPOSE:To markedly reduce the density ununiformity of a printed article by providing individual lead electrodes and a common ground electrode, whose respective lengths and widths are set to have the resistance values of the individual lead electrodes and the resistance value of the common ground electrode so that an electric current flowing through each heating element becomes substantially equal when power is supplied simultaneously to each heating element. CONSTITUTION:Individual lead electrodes 1-1...1-32 are connected to a heating element having a common electrode. A driver IC 2 is bonded on the wiring pattern of the individual lead electrodes via an insulating layer and connected to the individual lead electrodes through bonding terminals by a wire bond and the like. A common ground electrode 3 is connected to the driver IC 2 through ground terminals 3-1, 3-2, 3-3 by the wire bond and the like. In the case where each pattern of the individual lead electrodes 1-1, 1-2,...1-32 connected to the heating element, for example, the pattern width thereof, is held substantially identical, the resistance value of each individual lead resistance electrode is controlled by using, for example, a pattern 'a' formed in an inclined direction in addition to the pattern length formed orthogonally in the X-coordinate direction and the Y-coordinate direction.

Title: Communication method in bus system
Inventor: NAMEKAWA MAKOTO
IPC: G06F3/00
Filed: 1990-03-13
Abstract: PURPOSE:To curtail the current consumption quantity and to prevent the battery voltage drop by not supplying a voltage to a bus interface circuit, when the power source is turned off, and when it is unnecessary to execute a communication. CONSTITUTION:In the case usually a power source switch 5 is turned off, a voltage is not supplied to bus interface circuits 3a, 4a. In such a state, when necessity for executing a communication to other device is generated, a voltage is supplied to the own bus interface circuit, and also, a switch closing enable signal is sent to the other device through a request line 2, and a voltage is supplied to the bus interface circuit of the other device so that a data communication can be executed. In such a way, when the power source is turned off, the current consumption quantity can be decreased, and in the case of an on- vehicle bus system, it can be prevented that the battery voltage drops.

Title: Two-wire/four-wire conversion circuit
Inventor: KITAGUCHI TOSHIYOSHI
IPC: H04B3/03
Filed: 1987-03-19
Abstract: PURPOSE:To increase the quantity of mismatching attenuation on the side of two-wire line by setting the impedance on the side of a four wire to a pure resistance and providing an equilibrium connection network on an infiltrating cancellation line part. CONSTITUTION:For matching the load impedance 12 of the two-wire analogue line in an analogue trunk 11, the impedance 13 on the side of the four-wire is set to the pure resistance, and the equilibrium connection network 14 which prevents a reception signal from a four-wire digital channel 10 form infiltrating into the channel 10 is provided in the infiltrating cancellation line part 15 with the least influence of the impedance on the pure resistance. Thus, the equilibrium connection network 14 does not influence the quantity of mismatching attenuation on the side of the two-wire, and the input impedance 13 on a return loss on the side of the four-wire. Since a two-wire/four-wire conversion circuit can be designed without the consideration of influence on both, the quantity of mismatching attenuation on the side of the two-wire can freely be increased.

Title: Liquid drain apparatus
Inventor: OTSUKA SHIGERU
IPC: C02F1/00
Filed: 1985-03-29
Abstract: PURPOSE:To perform filtering reducing the mixing of solid components by a simple and inexpensive structure, in a liquid drain apparatus for taking out a liquid from a liquid tank storing a dirty liquid containing solid components, by utilizing the capillary sucking-up action by a nonwoven fabric. CONSTITUTION:A nonwoven fabric 5 mainly sucks up a liquid from the dirty liquid 4 in a liquid tank 1 and guides said liquid to the outside of the liquid tank 1 to fall the same in a drain pit 7. The solid component of the dirty liquid 4 is sedimented to the bottom of the liquid tank 1 during this time to be accumulated thereon but, because the sucking-up of the nonwoven fabric is performed over the entire suspended part of the nonwoven fabric 5 in the liquid, there is almost no effect of the sedimentation of the solid component. The drain liquid fallen to the drain pit 7 through the nonwoven fabric 5 is markedly lowered in the content of the solid component by the filtering action of the nonwoven fabric 5. The nonwoven fabric 5 can be easily replaced if necessary.
