Title: Auxiliary air controller for internal combustion engine
Inventor: SHIMURA YASUHIRO
IPC: F02D33/00
Filed: 1988-06-03
Abstract: PURPOSE:To prevent sound transmission by affording and shutting off communication between a silencer expansion chamber communicating to the upstream side are bypass path and the downstream side are bypass path by a duty ratio controlling electromagnetic valve and setting the ratio of the volume of said chamber to the area of said upstream side bypass path to a predetermined value. CONSTITUTION:In the normal travelling, an air controlling valve 2 is closed and a duty ratio controlling electromagnetic valve 1 is operated so that auxiliary air is sent to a silencer expansion chamber 12 from air bypassing path P3 through an air introducing path P3' and supplied to an engine E through an air introducing port 17, an air discharging port 18, an opening P4' and an air bypass path P4. An amount of supply of the auxiliary air is proportional to the duty ratio of a valve body 16 operated repetitively with high speed, so that the rotational frequency of the idling engine is maintained constant. Intake vibration sound in the operation of said valve 1 is effectively reduced by the predetermined ratio of the volume of said chamber 12 to the area of said path P3 so that it is hardly transmitted to the bypath path P3.

Title: Photo interference angular velocity meter
Inventor: OKADA KENICHI
IPC: G01C19/72
Filed: 1992-05-29
Abstract: PURPOSE:To maintain the stability of input and output scale factors, and a frequency response characteristic against a temperature fluctuation by alternately or intermittently applying a rectangular wave phase modulation as alternate phase modulation to right-turn and left-turn light propagating through an optical passage. CONSTITUTION:A phase modulator 16 performs phase modulation A=pi/4 (rad) for light-turn and left-turn light during the period I, and phase modulation A (rad) in the period II following the period I, alternately with the first rectangular wave modulation signal. Furthermore, phase modulation Bnot equal to A (rad) is applied to both of the light with the second rectangular wave modulation signal in the modulator 16 during the period III, and then phase modulation - B (rad) is applied during the succeeding period IV. This phase modulation with the second rectangular wave modulation signal is inserted alternately or intermittently, together with the phase modulation with the first rectangular wave modulation signal. This selection of phase modulation is performed by a clock CK8. As a result, even if a loss in an optical system fluctuates due to a change in ambient temperature or the like, the scale factors of input and output and a frequency characteristic can be kept stable.

IPC: H04N5/783
Filed: 1987-06-03
Abstract: In a method of recording video information in a record carrier (10), each picture (1) of NxM picture elements being divided into subpictures (2) of nxm picture elements, the video information of each subpicture is encoded in accordance with a transform coding (Ti) and recorded on the record carrier. Moreover, corresponding subpictures 11.1, 11.2, Fig. 4a) of two pictures (B1, B2) are compared with each other. To both subpictures a motion code (mci) is assigned, which motion codes are the same if the subpictures do not differ substantially from one another, but which are not the same (mc1, mc2, Fig.4c) if the subpictures (16.2, 16.3) differ substantially from each other. The motion is recorded on the record carrier (10) together with the coded information of the subpicture. Moreover, different transform codings (T1, T2, Fig.4a) may be applied to the subpictures. A higher-order transform coding yields a more accurate information of the subpicture which is encoded (Fig. 3). The associated transform code (Ti) is also recorded on the record carrier (10). Further, a method of reproducing video information from the record carrier (10) is described (Figs. 5, 6) and apparatuses for carrying out the two methods are described (Figs. 7 to 11).

Abstract: PURPOSE:To measure a component immediately by an enzyme sensor without maintaining a sample liquid in an constant temp. by measuring the temp. of the sample liquid and correcting the signal of the enzyme sensor. CONSTITUTION:The enzyme sensor 1 is brought into contact with the sample liquid 2 and the output from the sensor 1 is amplified with an amplifier 4. The change quantity is converted from an analog to digital value by an analog- to-digital converter 6 and the converted signal is inputted to a signal processing circuit 8. On the other hand, a temp. sensor 3 is brought into contact with the sample liquid 2 to measure the temp. of the liquid 2. The signal from a temp. measuring part 5 is digitally converted by an analog-to-digital converter 7 and the digital signal is inputted to the circuit 8. The circuit 8 takes the change rate of the sensor output by the sensor 1 and the temp. measurement data of the liquid 2 therein. The coefft. of the temp. memorized in the circuit 8 is read out of the measured temp. and the temp. is corrected by multiplying the change rate of the output by the coefft. of temp. The good measurement result is thus obtd. even if the temps. of a cleaning liquid, etc., vary from each other.
