Title: Oil infiltration preventing device for heat-driven engine
Inventor: KODA TOSHIHIDE
IPC: F02G1/053
Filed: 1990-09-04
Abstract: PURPOSE:To improve the oil infiltration prevention performance by setting the diameter of a cross head larger than the diameter of a power piston, and communicating the inner space of a crank case and the upper space of the cross head via a check valve and an oil separator. CONSTITUTION:The diameter phiD1 of a power piston 6 is set smaller than the diameter phiD2 of a cross head 8. When an engine is operated, the pressure Pd in the upper space 24 of the cross head 8 and the pressure Pb in the inner space 25 of a crank case are changed respectively. A check valve 28 is installed in the middle of a communicating pipe 26 between the upper space 24 of the cross head 8 and the inner space 25 of the crank case, thus the differential pressure is applied to the cross head 8 by the sucking effect of gas due to the pressure fluctuation of the inner space 25 of the crank case caused by the reciprocating movement of the cross head 8. The oil existing on the sliding face of the cross head 8 and scraped by the reciprocating movement of the cross head 8 is returned to the inner space 25 of the crank case by this differential pressure.

Title: Multi-layered antireflection film
Inventor: FUJINO TAKUO
IPC: G02B1/10
Filed: 1983-12-14
Abstract: PURPOSE:To obtain a stable reflection characteristic by forming, successively from a glass base plate side, the 1st layer consisting of Al2O3, the 2nd layer laminated with the three layers; a ZrO2 layer, ZrO2-TiO2 mixed layer and ZrO2 layer respectively having specific thicknesses with respect to the design wavelength and the 3rd layer consisting of MgF3 as the multi-layered antireflection film for optical parts on the glass base plate. CONSTITUTION:The 1st layer film having the thickness of lambda0/4 the design wavelength and the 2nd layer film laminated with the three layers; a ZrO2 film having lambda0/4, the mixed film of TiO2/ZrO2=0.07-0.13 having the refractive index slightly larger than the refractive index of said film to lambda0/8 thickness and a ZrO2 film having lambda0/8 thickness are formed on a glass plate successively from the base plate side. MgF2 is then formed to lambda0/4 thickness as the 3rd layer film on the 2nd layer film thereby manufacturing the multi-layered antireflection film. There is therefore no significant influence in the reflection characteristic in spite of a minor fluctuation particularly in production conditions and the antireflection film which has high film strength, decreases peak reflectivity and has at the same time a wide low reflection region is thus obtd. with less variance and at a stable and high yield.

Filed: 1988-09-21
Abstract: PURPOSE:To improve the reply frequency of an APC loop of a color signal by inputting a color signal and a 1H delay signal of the color signal to a subtractor for a period other than the burst period of a color signal and subtracting a delay signal from the color signal. CONSTITUTION:A 1H delay circuit 1 retarding an input signal by 1H (H is the horizontal scanning period) and outputting the retarded signal outputs a delay signal 101 having a reference burst part and retarding a signal 100 with a correlation at a prescribed period T by a time T and a switch means 51 gives the delay signal outputted from the delay means 1 for a period other than the reference burst period of the signal 100 to a subtraction means 2. The subtraction means 2 subtracts the inputted delay signal 101 via a switch means 51 from the signal 100 having the reference burst part and correlation at a prescribed period T. Thus, the response frequency of the color signal in the APC loop is increased.

Title: Contact sensor and case detector employing it
Inventor: NAGAI TAKAAKI
IPC: G01N35/04
Filed: 1994-09-29
Abstract: PURPOSE: To detect an object surely regardless of variation in the size or optical properties thereof by emitting a light from a light emitting element toward the surface of a contact piece when the contact piece touches the object and directing the reflected light toward a light receiving element. CONSTITUTION: When a rack 2 moves in the direction of an arrow A, a contact piece 7 touches the cap 3b of a sample case 3 and bent. At that time, a light emitted from the light emitting element in a photointerrupter 6 is reflected on the contact piece 7 and enters into the light receiving element in the photointerrupter 6. When the sample case 3 is not mounted on the rack 2, the contact piece 7 is drooping and the light emitted from the light emitting element does not enter into the light receiving element. Consequently, the photointerrupter 6 can determine presence of the sample case 3 by detecting the light entering into the light receiving element. When the photointerrupter 6 detects the sample case 3, the rack 2 moves a predetermined distance before stopping temporarily and the specimen in the detected case is sampled.

Abstract: PURPOSE:To reduce the capacity of a memory by decoding encoded data into blocks consisting of a different number of words from the encoded data and storing the data in the memory whose memory capacity is three times as large as the different number of words. CONSTITUTION:The data encoded by an encoding method which puts, for example, 16 samples in one block has every four samples decoded so that, for example, four sample data can be decoded at a time. Then the decoded data are stored in the buffer RAM which has 12-sample capacity three times as large as, at least, four samples. Then the stored data are read out of the buffer RAM and converted in pitch. The pitch conversion extends over two sections like sections 1 and 2 at a maximum. Therefore, the buffer RAM needs to have only capacity which is large enough for two sections plus one section to be decoded, i.e., three sections consisting of 12 samples.
