Title: Gas laser equipment
Inventor: TADA TERUSHI
IPC: H01S3/034
Filed: 1994-03-16
Abstract: PURPOSE:To increase output power and improve the life of an optical window, by reducing the thickness of the optical window while maintaining the mechanical strength, and reducing the transmission loss of the optical window. CONSTITUTION:The title gas laser equipment consists of a laser tube 11 in which laser medium is sealed, optical windows 12, 13, and a resonator constituted of an output mirror 14 and a total reflection mirror 15 which oscillate laser light. Since the optical window has a semispherical shape, the thickness can be reduced as compared with a planar mirror. Thereby the loss in a resonator and the deterioration of the optical window can be restrained, and high output and long life are realized.

Title: Electronic wristwatch with pressure sensor
Inventor: AYUSAWA HITOMI
IPC: G01L9/00
Filed: 1986-03-03
Abstract: PURPOSE:To attain reduction in power consumption by enabling the low power operation of an A/D converter, by a method wherein it is detected that the output of an amplifying circuit is a prescribed value or more to change over not only amplification factor but also the number of bits. CONSTITUTION:A counter circuit 6 performs counting through a comparator 5 until the output of a pressure sensor 1 through an amplifying circuit 2 coincides with the output of an integrating circuit 4 integrating the reference voltage from a reference voltage generating circuit 3 and the pressure detection output by the sensor receives A/D conversion to be displayed through CPU10. In this case, when the output level of the circuit 2 reaches a predetermined value or more, the amplification factor of the circuit 2 is lowered by an amplification factor change-over circuit 7 through a level detection circuit 9 and, at the same time, a number-of-bit change-over circuit 8 is changed over and the cycle of the clock counted by the circuit 6 becomes long. By this constitution, A/D conversion is performed by low power operation even if detection output becomes large and the reduction in power consumption is attained.

Title: Catalyst formed in novel cylindrical shape
Inventor: SHIOSAKI KEN
IPC: B01J35/02
Filed: 1980-04-07
Abstract: PURPOSE: To provide a catalyst for a stationary catalyst bed which is specified of the size of a cylindrical shape, is low in resistance, is large in effective surface area, and is good in heat conduction among catalyst particles or between the catalyst and an inactive catalyst diluent.  
     CONSTITUTION: This catalyst is cylindrical in shape which is within the range of 3W6mm outside diameters of the circle, ≥1.0mm inside diameter, ≤1.5mm thickness and 3W6mm heights or consists essentially of the shapes within this range. In this case, the lower limit of the thickness is determined by mechanical strength, and is selected at suitable numerical values that withstand practicable use depending upon used raw material powders, binders, etc. For example, the outside diameter of the circle of the cylindrical shape is selected at 4W5mm, the inside diameter at  1.5W2.5mm and the thickness at 1.0W1.5mm. It is best to accomplish molding with a compression type pellet making machine. It has been revealed that although the initial mechanical strength of this catalyst is somewhat low there are practically no problems as far as the compressive breakdown strength in the diametral direction is around 0.2kg and that powdering is smaller than spherical and columnar shapes.

IPC: B63H3/10
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a blade angle detecting device capable of imparting stable ascending force to a feedback ring (a rotary plate) with simple constitution. SOLUTION: A marine propulsion device comprising a turning cylinder 9, a vertical driving shaft 4, a propeller shaft 3, propeller blades 1 and a servo 14 for setting the pitch of the propeller blades 1, has a blade angle transmitter 23. A guide rod 33, and a rotary plate 31 that can be elevated along the guide rod 33 are provided in the turning cylinder 9. A ring 22 of an input shaft of the blade angle transmitter 23 is slidably engaged with the peripheral edge part of the rotary plate 31. The rotary plate 31 and the servo 14 are connected by a chain 20. A hydraulic cylinder 32 energizes the rotary plate 31 upward so that the chain 20 does not become loose. Since a surface part sliding when the rotary plate 31 vertically moves is not an inner diameter part of a center hole hard to machine but the guide rod 33, the device can be simplified.  Since the independent hydraulic cylinder 32 is used as a hydraulic mechanism for energizing the rotary plate 13 upward, it can be easily miniaturized, and the ascending force of the rotary plate 31 can be easily stabilized.

Title: Operation controller for compressor in car air conditioner
Inventor: SHIBATA TAKANORI
IPC: B60H1/32
Filed: 1981-03-31
Abstract: PURPOSE:To improve the efficiency, durability, and reliability of an electromagnetic coil by increasing the excitation current of an electromagnetic clutch which connects an engine and a compressor using the detection output of a drive shaft acceleration or compressed cooling load increase signal. CONSTITUTION:When an engine performs constant revolution and when the cooling load of a compressor is fixed and lower than a specified value, the output Vr of an OR gate 25 is O. When there is the output of an air ventilator control circuit 26 in this condition, the excitation current Ic of an excitation coil 10 is kept in a small value. In this case, if the number of engine revolutions changes suddenly, and they are detected by detecteors 16 and 17, the number of revoltions is converted into acceleration, input to each comparators 21 and 22, and compared with the reference values alphas and betas. When the acceleration exceeds the reference values, output Vr is output from the OR gate 25. The reference voltage, current ratio, and excitation current are increased. As a result, the efficiency, durability, and reliability can be improved without applying the excitation current that is not required for the operation of the compressor.

Abstract: PURPOSE:To accurately execute matching at high speed without considerably increasing a calculation amount even when an image size is enlarged. CONSTITUTION:Coarse search is executed to calculate a correlation value between a template 41A and an image by moving the template 41A for five picture elements inside the image. An area to maximize the correlation value provided by the coarse search is decided as a first reference area 51A and an area to show the value next to the maximum value is decided as a second reference area 51B.
