Title: Wear resistant ceramic and its production
Inventor: OKADA AKIRA
IPC: F01L1/20
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To secure wear resistance and strength and to improve durability by coating a surface layer ceramics having fracture toughness of a specified range onto the surface of a base ceramic having fracture toughness of not less than a specified value and constituting at least a specified ratio of the base ceramic and the surface layer ceramic using the same phase. SOLUTION: The fracture toughness of a base ceramic and surface layer ceramic are >=8.0 and 3.0 to 6.0 MPa.m1/2, respectively, and the ratio of the phase constituted of the same phase is not less than 60 wt.%. The wear resistant ceramic is composed of the base ceramic 2 and the surface layer ceramic 3. When a crack C is introduced by accidental impact load into the surface layer ceramic 3, the surface roughness becomes large and the amount of wear rapidly is increased. As the base ceramic 2 has high fracture toughness, propagation of the crack C is stopped by the high fracture toughness and actualization of the surface damage can be prevented. The thicknesses of the base ceramic 2 is >=1 mm and the coating film thickness of the surface layer ceramic 3 is 0.1 to 100 μm, and preferable main phase is silicon nitride.

Title: Clear polyester film for vapor deposition
Inventor: OKADA SHINICHIRO
IPC: B41M1/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To prepare a clear polyester film for vapor deposition which is excellent in adhesion to vapor-deposited metal oxide, esp. adhesion after retorting, by incorporating fine porous silica particles having specified properties into the same. SOLUTION: This polyester film contains 0.005-20 wt.% fine porous silica particles which are substantially mononuclear and have an average particle size of 1.0-10 μm, a micropore vol. of 0.1-1.0 ml/g, an average micropore size of 0.05-100 nm, and an oil absorption of 200 ml/100 g or lower. Pref., the cloudiness of the film is 0-5%. The fine porous silica particles are required to be substantially mononuclear. Silica particles in the form of aggregates are unfavorable since such aggregates have a high moisture absorptivity and each aggregate has an insufficient strength, and as the results, defects in a vapor-deposited thin film layer are liable to occur during retorting and the gas barrier properties are degraded. If necessary, the silica particles may be subjected to a surface treatment for preventing aggregation and then dispersed in a resin.

Title: Analog signal selecting device
Inventor: YANO TAKASHI
IPC: H03K17/62
Filed: 1985-06-29
Abstract: PURPOSE:To reduce crosstalk because of a signal not selected passing a parasitic capacitor by applying logarithmic conversion to plural analog input signals and outputting the selected signal only while being subject to inverse logarithmic conversion. CONSTITUTION:A differential voltage VdA is inputted to transistors (TRs) Q11 and Q12 and a voltage drop in response to the collector current of the TR Q11 is produced between the base and emitter of the TR Q13. The voltage drop is logarithmic compression of the voltage VdA. The voltage drop is impressed to a TR Q15. This is applied also to TRs Q14, Q16. A signal applying logarithmic compression to a differential input voltage VdB is inputted similarly to TRs Q25, Q26. When a high and a low level signal are inputted respectively to a selection signal terminals 1, 2, a current flows between the collector and emitter of the TRs Q15, Q16 but no current flows to the TRs Q25, Q26. As a result, the signal inputted to the TRs Q15, Q16 is subject to inverse logarithmic conversion and a collector current flows to resistors R101, R102, but no collector current of the TRs Q25, Q26 flows. Thus, the current flowing to the resistor is not affected by parasitic capacitors C25, C26.

IPC: H01L27/15
Filed: 1977-11-29
Abstract: PURPOSE: To obtain a luminous element which features the light emission over a wide wavelength range, by sticking the luminous material on the semiconductor substrate of a narrow band gap to cause a high field region on the surface of the substrate and then giving the energy more than the energy barrier to secure the light emission.  
     CONSTITUTION: Reverse conduction-type region 1 featuring a narrow band gap is formed through diffusion on uniconduction-type semiconductor substrate 5, and insulator film 2 is coated on the entire surface. The opening is then provided to film 2 positioned on region 1, and luminous material 3 featuring a wider energy gap than region 1 is coated on the surface of exposed region 1 to form light transmissible conductive gate 4 on the surface. The pulse bias featuring the quick rise, with which no minor carrier is stored on the surface, is applied between region 1 and gate 4. Thus, the high field region is caused on the surface of region 1, and the accelerated carrier enters within layer 3 going over the energy barrier to cause the light emission. Thus, the element array featuring the different luminous colors can be formed on the same substrate.

Title: Backlight correction circuit for video camera
Inventor: SHIMADA MITSUHIRO
IPC: H04N5/235
Filed: 1987-06-08
Abstract: PURPOSE:To automatically eliminate a backlight state at the inside of a video camera without any cumbersome manual operation by detecting a backlight state based on a video signal obtained by a sensor, and automatically correcting backlight state. CONSTITUTION:A microcomputer 10 judges whether or not there is a need to apply backlight correction to a video signal Sp based on comparison signals Sc1, Sc2 from comparators 8, 9. That is, the presence/absence of a white peak part above 100% in the signal Sp is examined, and in case the absence is judged, the backlight correction is decided to be unnecessary, but in case of necessity judged, the black level is compared with a specified value. When the black level is higher than the specified value, the backlight correction is decided to be unnecessary, but when lower, whether proportion occupied by the white peak part is higher than a determined value or not is decided. If the proportion of the white peak part is lower than the value, the backlight correction is decided to be unnecessary, but if larger, the computer 10 decides on the necessity for backlight correction, hence a backlight detection signal S1 is outputted to a processing circuit.
