Filed: 1992-06-09
Abstract: PURPOSE:To prevent noise such as overshoot or undershoot from being generated in an output signal because a current is supplied to a load in a high on- resistance state of a transistor(TR) by the work of a MOS capacitor when a small load is connected to an output terminal DQi. CONSTITUTION:The circuit is an improved output driver circuit 10, which is provided with MOS capacitors 3, 4 arranged respectively between gates of NMOS TRs 1, 2 having a sufficient mutual conductance to drive a large load and points of reference potential of Vref1, Vref2. For example, when an input signal inverse of phi1 falls down, the capacitance of the MOS capacitor 3 is increased as a gate voltage phi1 of the TR 1 rises.

The output of the multiplier 26 is limited in band and, by discriminating the correlation of the signals obtained by limiting the band, the delaying amount corresponding to the time required for radio waves to go to and come back from an object from and to its own vehicle is detected. A distance detecting circuit 36 calculates the distance to the object based on the detected delaying amount. The output of the BPF 32 is further frequency-converted by means of another frequency conversion circuit 40 and converted into a voltage by means of an F-V converter 42. The output of the converter 42 contains a voltage component related to a Doppler frequency and a relative speed calculating circuit 44 calculates the relative speed of the object from the component related to the Doppler frequency.

Title: Tooth-tip sealing mechanism for gear pump
Inventor: TERUYAMA HIDEO
IPC: F04C2/18
Filed: 1981-09-22
Abstract: PURPOSE:To prevent the gear track of a seal block from becoming deep unnecessarily in high-speed, high-pressure operation of a gear pump, by selecting the substantial tooth-tip sealing length of the seal block at a proper value. CONSTITUTION:The length l from a point A to a point B, constituting the tooth- tip sealing length of a seal block 9, is selected to be nearly equal to an adjacent pitch P (but l>P). In the length l from the point A to the point B constituting the substantial tooth-tip sealing length, pressure in the tooth space is changed from the level of suction pressure to the level of discharge pressure, but the process of this pressure change is extremely stable. Therefore, by determining the loading force according to the pressure in the tooth space, it is enabled to prevent the gear track from becoming deep unnecessarily.

Title: Thermal ribbon construction
Inventor: KINOSHITA NAOHISA
IPC: B41M5/42
Filed: 1987-06-17
Abstract: PURPOSE:To clearly print even on a rough paper having low flatness, by laminating a heat-resistant base film, a heat-softenable layer, a porous heat-resistant and flexible intermediate ink layer permeable to the material of the heat-softenable layer, and an ink layer. CONSTITUTION:The heat of a head 8 is transmitted to a heat-softenable layer 3 through a base film 2, and is transmitted therefrom to an ink layer 5 through an intermediate film layer 4. The heat-softenable layer 3 is softened or melted. Since the heat-softenable layer 3 receives a higher pressure at parts corresponding to projected parts of a paper 7 and a lower pressure at parts corresponding to recessed parts of the paper 7, the layer 3 flows to the lower-pressure parts corresponding to the recessed parts of the paper 7. The fluid parts of the layer 3 function to uniformize the internal pressure thereof, whereby the layer 3 permeates into and through a fine part at the lower- pressure parts of the intermediate film layer 4, bulges along the recessed parts of the paper 7, and thereby conforms the ink layer 5 at the parts to the recessed parts of the paper 7. Since the quantity of the fluid material smaller at the projected parts of the paper 7 and greater at the recessed parts of the paper 7, the heat capacity thereof is also greater at the recessed parts, resulting in a sufficient quantity of heat for transfer.
