Title: Optical modulator
Inventor: IMANISHI YASUO
IPC: G02F1/35
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a new optical modulator which can separate and control light mixed with modulated light when a light signal is modulated fast in light form. SOLUTION: Three light pulses of signal light, control light, and compensation light which are linearly polarized are made incident on a signal light input terminal 1, a control light input terminal 2, and a compensation light input terminal 3. The respective light pulses are introduced into a signal light polarizer 4, a control light polarizer 5, and a compensation light polarizer 5 respectively and the signal light and control light after being multiplexed coaxially by a coupler 8 are guided in a tertiary nonlinear optical medium 10. When passing through the coupler, the signal light and control light have such polarization relation that the signal light is at -45 deg. and the control light is at 0 deg..  The nonlinear optical medium 10 modulates the phase of the signal light with the control light to induce modulated light of a component crossing the direction (-45 deg.) of polarization of the signal light at the time of incidence at right angles (+45 deg.). Those output lights are multiplexed by a coupler 9 with compensation light having passed through the compensation polarizer 6 and the control light and compensation light have photoelectric fields removed by canceling each other. The polarizer 7 transmits only the modulated light and outputs it to a modulated light output terminal 11.

Title: Actual-sound monitoring system
Inventor: TAWARA AKIRA
IPC: G01H3/00
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To obtain an actual-sound monitoring system by which effective data can be recorded with high efficiency by a method wherein an effective-value noise signal is recorded preliminary when a measured noise value is at a reference noise value or higher and the effective-value noise signal is recorded formally when the state of the reference noise value or higher is continued for a prescribed reference time or higher. SOLUTION: A weighting network circuit 2 converts the output signal of a sound-level meter 1 into a noise signal which is weighted by an A weighting characteristic of auditory sensation, and an effective-value detection circuit 3 effective-value-detects its output so as to generate a measured noise value. An internal storage medium 4 preliminary records an effective-value noise signal when the measured noise value is at a preset reference noise value or higher. In addition, when a state that the measured noise value is at the reference noise value or higher is continued for a prescribed reference time or higher, the effective-value noise signal which is recorded preliminary is recorded formally as effective data. An external sotrafe medium 5 records the effective data. By this constitution, the effective data on a noise can be recorded with high efficiency.

IPC: F16H61/00
Filed: 1988-12-29
Abstract: PURPOSE:To control rise of the shifting speed according to the size of acceleration demand properly by setting the rise speed of the shifting speed with the through condition value when acceleration demand is sensed from throttle condition value. CONSTITUTION:An ECU 120 senses acceleration demand on the basis of the degree of throttle opening sensed by sensor 161 and its rate of change, and calculates the belt ratio from the numbers of revolutions of a primary and a secondary pulley sensed by sensors 165, 166, and further current mode (L or H) and the system ratio, and it calculates further the target system ratio upper/lower limit values from the degree of throttle opening, running mode, and car speed. It is then judged whether an aux. transmission 40 is to be put in low speed or high speed mode, and the shifting direction and speed in a continuous transmission 30 are judged from the acceleration demand, belt ratio, and system ratio sensed from the rate of change in the degree of throttle opening, to serve for control of the rise of the shifting speed by a CVT shifting motor 101. This prevents drop of the drive force in the initial period of acceleration.

Title: Sewing machine device
Inventor: OGAWA TATSUYA
IPC: D05B3/04
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a uniform degree of contact of thread over a whole area of tight sewing, by making the amount of lateral movement of one seam of each of sewing data shorter than the amount of lateral feeding due to one-time feed dog, and by inserting a combination of a negative needle swinging and a lateral feed of a positive feed dog into a second sewing section. CONSTITUTION:In case a close sewing is done by alternating a section A where needle- swinging and normal and reverse feeding are made and a section B where sewing is made with needle-swinging, a lateral feeding and a normal and reverse feeding combined, in the section A one needle swinging is made to include, e.g. three steps, the length AL of the section A is taken to be AL<W with respect to the maximum amplitude W of the needle swinging. That is, the section B is shortened, and the amount of lateral movement of one stitch (from a needle-falling point to the next needle-falling point) in the sections A and B is set to be shorter than the amount of lateral feeding by one-time feed dog. By so doing, the needle-swinging is returned by -1 step in the section B, 4-step lateral reel is performed by needle-swinging conversion, and while maintaining the pitch of a sewing line at 3-steps, the same as the section A, a needle 21 is enabled in the section B to return to its initial position, thereby enhancing the degree of closeness.
