Title: Photographic lens with variable optical characteristic
Inventor: ENDO HIROSHI
IPC: G02B9/64
Filed: 1986-12-11
Abstract: PURPOSE:To vary image plane characteristics optionally by composing a photographic lens of three lens groups, moving those under specific conditions for high-performance floating while aberrational variation is compensated excellently, and moving a 3rd lens group on an optical axis. CONSTITUTION:This photographic lens has three lens groups, i.e. a 1st lens group I with positive refracting power, a 2nd lens group II with positive refracting power, nd a 3rd lens group III. When focusing is changed from an infinite- distance body to a short-distance body, floating is performed by moving the 1st-3rd lens groups I-III so that two air gaps formed by both of two adjacent groups increase. Then, when the short-distance body is put in focus, only the 3rd lens group III is moved on the optical axis to vary optical characteristics. Consequently, a stopping-down quantity is reduced at the time of, specially, short-distance photography and image plane charcteristics are varied mainly and optionally.

Title: Tape guide device
Inventor: TAKAGI NOBUAKI
IPC: G11B15/60
Filed: 1991-11-12
Abstract: PURPOSE:To prevent the generation of buckling of a tape by flanges and to stabilize the traveling property of the tape by providing a stationary part which does not rotate in the central part of a revolving roller and vertically bisecting the revolving roller. CONSTITUTION:A stationary part 8 which does not rotate is formed on a revolving shaft 3. A revolving rollers 6, 7 are disposed above and below via the stationary part 8. Tapered parts 6b, 7b are respectively provided on the rollers 6, 7. The stationary part 8 is formed to the diameter slightly smaller than that of the rollers 6, 7. Thus, the coefft. of friction with the magnetic tape in the stationary part 8 slightly increases to the coefft. larger than the coefft. of friction in the rollers 6, 7. The force for moving the magnetic tape 5 toward the stationary part 8 is, therefore, generated in the magnetic tape and such force is assisted by tapered parts 6b, 7b. Consequently, the force tending to move a tape 5 to the central part in the transverse direction of the tape is generated at all times in the tape 5 and the restricting force from the flanges 1, 4 is relieved. The traveling of the tape 5 is stabilized.

Title: Test piece for determining component in liquid sample
Inventor: HIRAYAMA KOJI
IPC: G01N33/52
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To eliminate the fluctuation of measurement due to the difference of the color of individual liquid sample by setting the color of cover covering the detecting part of a reagent layer such that the reflected light from the cover has substantially no effect on the wavelength to be measured. SOLUTION: A cover 5 is applied to a support 1 such that a capillary chamber 4 is formed between the cover and a reagent layer 3 serving as a reflection layer. The cover 5 has reflectance lower than 30%, preferably lower than 10%, so that the light reflected thereon has substantially no effect on the wavelength to be measured, and processed to be black or transparent so that the light can be absorbed over a wide wavelength region. At the time of measuring the components in a liquid sample, e.g. a blood sample, the sample is dripped through a sample supply hole 51 and caused to react on the reagent layer 3 and then the reflectance is measured from the porous film 2 side through a through hole 11. The light transmitted through the reflection layer in reagent layer 3 is absorbed by a colored cover 5 thus eliminating excess reflected light.  Consequently, fluctuation in the measurement due to the difference of the color of individual liquid sample is eliminated.

Title: Sewing machine
Inventor: ITO HIDEKAZU
IPC: D05B57/30
Filed: 1990-10-31
Abstract: PURPOSE:To enable synchronous relation between a shuttle and a needle rod, to be normally kept, and improve the reliability of sewing working by detecting the rotational position of the shuttle with a shuttle position detecting means, and by correction-working the shuttle with a shuttle driving motor when the rotational state of the shuttle falls out of a normal state, to control the shuttle so that the rotational state of the shuttle may be reset to the normal state. CONSTITUTION:When a shuttle 1 is set in a locked state at an Original point position and is set in a state that it is not rotated at all, then the shuttle 1 is reversely rotated step by step, and in other words, it is rotated in the direction of an arrow head B. Accordingly, if the shuttle 1 falls out of the locked state and is reversely rotated, the shuttle 1 gets out of the original point position, and so a shutter 11 is removed from the light course of a light sensor 9, and the output of the light sensor is switched to a low level, and the output of original point position detecting signal is not generated. In this step, in order to stop the reverse rotation of the shuttle l straightaway and to return the shuttle 1 to the original point position, the shuttle 1 is driven to be rotated forward by one step, and after that, till the shuttle 1 is returned to the original point position and the output of the original point position detecting signal is generated from the light sensor 9, the shuttle 1 is repeatedly driven to be rotated forward. As a result, even if a load to be applied to the shuttle by the influence of cloth thickness or the like at the time of sewing is fluctuated, synchronous relation between the shuttle and a needle stem can be normally kept, and the reliability of sewing working can be improved.
