IPC: G02B15/15
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To obtain an objective optical system whose entire length is short and whose lens outside diameter is small through it can realize enlarging observation by moving a 2nd group on an optical axis so that variable power action may be performed and making it satisfy specified conditions. SOLUTION: This optical system is constituted of a 1st group G1 having positive refractive power, a 2nd group G2 having negative refractive power and a 3rd group G3 having positive refractive power in order from an object side. By moving the 2nd group G2 on the optical axis, the variable power action is performed, and the system satisfies the conditional expressions: 0.1<|1/ f2 (DW-DT)}|<2, 1<|(fW.fT)<1/2> /f1 |<2. Provided that f1 and f2 are the focal distances of the 1st and the 2nd groups G1 and G2, DW and DT are intervals between the 1st and the 2nd groups G1 and G2 at a wide angle end and a telephoto end, fW and fT are the focal distances of the entire system at the wide angle end and the telephoto end, respectively.  Thus, the occurrence of aberration in the 2nd group G2 is restrained and the aberration is kept excellent, and the refractive power of the 2nd group G2 is made strong while keeping the aberration excellent.

Title: Vulcanizing tank
Inventor: FUJIYAMA HISANORI
IPC: B29C35/02
Filed: 1979-04-30
Abstract: PURPOSE: To improve the heat dissipation from the fluidized bed by means of an openable shutter provided between the vulcanizing tank and the air exhaust hood arranged at a proper space in the vulcanizing tank employing a granular solid for the heating medium.  
     CONSTITUTION: A bottom ceramic porous plate 1 is arranged in the vulcanizing tank 5 covered with a heat insulator 8. Hot air is blown in through the blow-off port 10 and floats the vulcanizing granular solid to form a fluidized bed 3. An unvulcanized extrusion rubber product 4 is carried into the bed 3 to vulcanize. The lower position of the exhaust duct 6 causes air to flow too fast making the density and height of the fluidized bed unstable. To prevent this, the exhaust hood 7 having the exhaust duct 6 is sufficiently separated from the vulcanizing tank 5. At the same time, a shutter openable with a cylinder 11 is provided to prevent the heat dissipation while facilitating the monitoring of the rubber product 4.

Title: Method and device for measuring pressure for food refrigeration
Inventor: TAKADA TAMOTSU
IPC: A23L3/36
Filed: 1986-03-12
Abstract: PURPOSE:To measure the pressure in food remotely by fixing a pressure receiving part atop of an insertion cylinder inserted into the food and detecting pressure applied to this pressure receiving part. CONSTITUTION:The insertion cylinder 1 is inserted into the food to the position where the pressure is measured and the food is frozen while the pressure receiving part 2 provided atop of the insertion cylinder 1 is brought into contact with the internal surface of the food; and then the food expands in the freezing process and internal pressure is generated in the food. This pressure variation is detected by a pressure sensor 5 as the force of the food surface which contacts the pressure receiving part 2 and pushes the pressure receiving part 2 when the food expands and the pressure sensor 5 sends a signal an electric signal in proportion to the pressure applied to the pressure receiving part 2. Then, this electric signal is pressure-converted 6 into a standard electric signal, which is received by a receiving meter 17 through a lead line 8. The receiving meter 17 records and indicates the pressure variation and adjusts cooling conditions such as the temperature and flow rate of a cooling medium on the basis of the pressure variation. Consequently, the pressure in the food is measured remotely.

Title: Diagonally stringed racket
Inventor: OKAMOTO TAKESHI
IPC: A63B51/08
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To make the tension adjustment of vertical and horizontal strings easy and obtain a uniform repulsive force from vertical and horizontal strings by stretching the strings diagonally to the axis of a racket. SOLUTION: Racket strings 1 are stretched diagonally to the axis 2 of a racket. On such occasion, preferably the strings 1 intersecting each other are stretched non-perpendicularly, thereby making the strings 1 intersecting each other nearly equal in length in a wide range near the center of the face and making the tension of the strings 1 comparable, allowing the tension of the strings to be adjusted easily. As a uniform repulsive force is obtained from both strings 1, it is possible to make strong shots. By making both strings 1 intersect each other non-perpendicularly, the range where both strings 1 have the same length expands further, allowing a racket to demonstrate its great power in a game.

Title: Linearity measurement of d/a converter
Inventor: MATSUDA MASAO
IPC: G01R31/00
Filed: 1982-04-02
Abstract: PURPOSE:To achieve a simple measurement with the removal of noises by inputting a conversion output of a D/A converter into an A/D converter at each one clock as amplification signal of an analog output corresponding to a change of one clock to integrate digital outputs as obtained each clock. CONSTITUTION:A clear pulse is sent out to a counter 3 via a clock generator 2 from a control section 1a and output thereof is inputted into a DUT4 to be converted to analog which is inputted into a differential amplifier 7. As the other input of the differential amplifier 7 is ''0'', the output of the differential amplifier 7 at the current time corresponds to KX1 LSB of the DUT4, where K represents an amplification gain of the differential amplifier. A signal for each clock inputted into the A/D converter is multiplied with the differential amplifier by K times in the unit step of the A/D converter due to a differential voltage between a conversion voltage in a clock and a hold conversion voltage with a sampling hold delayed by one and the voltage thereof is converted to digital. Thus, the results are integrated as digital output value with the control section. For example, setting at a constant value, K=100-1,000 or so can almost override effect of noise.
