Title: Optical waveguide circuit
Inventor: ARAN NATSUTSU
IPC: G02B6/122
Filed: 1986-12-10
Abstract: PURPOSE:To decrease relative interference by leaking light and to improve the operating characteristic, accuracy and reliability of circuits by providing a dummy path having the refractive index higher than the refractive index of optical waveguides for capturing the leaking light from the waveguides to an inter-waveguide region provided with plural pieces of the optical waveguide paths in proximity to each other. CONSTITUTION:The Z-axis direction of the crystal is determined at the thickness direction of a substrate 1 and the waveguides are formed by diffusion of Ti if the substrate 1 is an LiNbO3 crystal. The dummy path 4 increased in the refractive index can be formed in the substrate region between the waveguides 2A and 2B by substituting the lithium atoms in the crystal with hydrogen atoms for the specific width, thickness and length. Light which is the light propagating in the waveguides 2A, 2B, enters the boundary face at the angle above the critical angle of total reflection and leaks to the outside of the waveguides enters the dummy path 4. Since the dummy path 4 has the refractive index higher than the refractive index of the waveguides, the greater part of the leaking light is confined therein and the quantity of the incident light on the adjacent waveguides decreases. The dummy path having the extremely high refractive index as compared to the Ti-diffused waveguide is formable by hydrogen substitution in the Z-axis direction of the crystal particularly when this method is applied to an LiNbO3 substrate. A particularly high effect of confining the leaking light is then obtd.

IPC: B60W10/10
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To suitably prevent occurrence of a shock caused by a speed shift fixing output from a VSC control device. SOLUTION: When a speed shift fixing instruction determining means 166 determines that a turning maneuver control means 158 delivers an instruction for fixing a speed shift stage of an automatic transmission 14, when a speed shift stopping means 168 stops a speed shift of the automatic transmission 14 during advancing, a method of stopping a speed shift of the automatic transmission 14 is changed in accordance with a degree of advancing of the speed shift. Accordingly, it is possible to avoid disengaging a hydraulic frictionally engaging device at once, which has already started the engagement, thereby it is possible to suitably prevent occurrence of a shock caused by a speed shift fixing output delivered from the turning maneuver control means 158.

Title: Trouble shooting apparatus for wheel speed sensor signal system
Inventor: TODA TOSHIHIRO
IPC: B60T8/1761
Filed: 1991-11-13
Abstract: PURPOSE:To enable detection of troubles of disconnection and short-circuiting of a signal line by a method wherein a stabilization voltage and a resistance are used in the signal line to give the line a specified voltage and an input voltage into an A/D conversion input port is monitored with respect to the specified voltage. CONSTITUTION:When a signal line 60 is normal, a line 71 is given a signal voltage which varies centered on a voltage as obtained by dividing a power source voltage Vcc by resistances R4 and R5 and the voltage is introduced into an A/D conversion input port of a microcomputer 51 as reference voltage through a line 73. When a line 60 is disconnected, a capacitor C1 is charged by the current through the resistances R4 and R2 and a voltage Vcc is led out to the line 73, so that an input voltage of an A/D port turns to the voltage Vcc. When the line 60 is short-circuited to a ground potential, the capacitor C1 discharges by the current to the line 60 and input voltages of the line 73 and the A/D port turn to the ground potential. Thus, troubles of disconnection or short-circuiting of the line 60 can be detected by monitoring the input voltage to the A/D port.

Title: Ink jetter
Inventor: YOSHINO MICHIO
IPC: B41J2/045
Filed: 1985-12-26
Abstract: PURPOSE:To prevent effectively the decrease in jet speed following the increase in volume, by generating the pressure pulse having sharp top and rear parts and the inclination part the amplitude of which increases as time elapses between those both end parts in ink. CONSTITUTION:The sharp fall part of a voltage pulse P immediately appears in a lead wire 21 via a capacitor 32. If the electrostatic capacity value of the capacitor 32 is made approx. the same as the electrostatic capacity value of a piezoelement 20, the voltage pulse P sharply falls to the amplitude of approx. one half thereof. When the sharp fall following the charge of the capacitor 32 has ended, the voltage value of the voltage pulse P increases as time elapses at the time constant determined by the product of the electrostatic capacity value of the piezoelement 20 and the resistance value of a variable resistor 33. Thereafter, when the voltage pulse rises (returns), the capacitor 32 and the piezoelement 20 are suddenly discharged via a diode 34 and the voltage pulse P sharply returns. Therefore, the voltage pulse P shows the waveform having sharp rise and fall parts and the inclination part the amplitude of which increases as time elapses in its midway. Thereby, the decrease in jet speed following the increase in volume comes not to be generated.
