Title: Infrared absorption composition
Inventor: SUZUKI YOSHIAKI
IPC: C09K3/00
Filed: 1984-09-13
Abstract: PURPOSE:To provide an infrared absorption composition suitable for a filter by incorporating a specific complex compd. as an active component with the composition so as to absorb an infrared light, especially at a long wavelength range. CONSTITUTION:More than one kind of the complex compd. shown by the formu la is incorporated with the infrared absorption component in an appropriate amount. In the formula, R and R' are a hydrogen atom, an alkyl group, an aryl group and a heterocyclic ring group; [Cat] is a cation for neutralizing the complex compd.; M is Ni, Pd and Pt. The above-described composition shows the max. absorption at the long wavelength range, especially >=900 n m wavelength range and has a high solubility for an organic solvent and a good compatibility for a film forming binder. Therefore, the above-described composition is preferable to use to a plastic film for a photodetector in a semi conductor laser. Besides, a metal element shown by the symbol M in the formula is useful to fine-adjust the interrelation between the max. absorption wavelength of the metal element and a molecular extinction coefficient.

Title: Semiconductor pressure difference detector
Inventor: SHIMAZOE MICHITAKA
IPC: G01L9/04
Filed: 1982-11-04
Abstract: PURPOSE:To make the relationship between pressure and output linear even at the measuring time for low pressure, by providing regions having different thicknesses in a strain yielding part, and forming strain sensitive elements on the thick strain yielding parts. CONSTITUTION:The diaphragm part of a semiconductor pressure difference detector comprises two stepped parts having different thicknesses, i.e., convex strain yielding parts 34 having a relatively thick size and diaphragm parts 36 having th thickness thinner than the part 34. The end parts of the convex strain yielding parts 34 are connected to a fixing part 30 and form a cross shape. Gage resistors 38 in a P shape are formed on the upper surfaces of the convex strain yielding parts 34 and take out full bridge outputs by pressure. In this constitution, the convex strain yielding parts 34 can yield large strain based on small forces, i.e., low pressures. Therefore, the relationship between the pressure and the output can be made linear even at the measuring time of the low pressure.

Title: Sheet material carrying device and image reading device
Inventor: OKUBO AKIO
IPC: H04N1/00
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To move a stopper member without using a solenoid by providing a drive transmission means with a delay transmission mechanism which transmits drive force of a diving means to the stopper member, and then transmits the drive force to a preliminary carrying means. SOLUTION: When documents are deeply inserted in the direction of the arrow G, the leading ends of the documents butt against a stopper member 68. When an instruction to send a signal is given on the operation panel of an operating part, a drive motor rotates to rotate and drive a required gear. Consequently an ejecting roller and a carrying roller 17a are rotated in a sheet carrying direction and also a separating roller 16a and a preliminary carrying roller 51 are rotated in the sheet carrying direction with delay caused by a mechanical timer.  Thus, while the documents held between the preliminary carrying roller 51 and a preliminary carrying press plate 77, constituting a preliminary carrying part are handled by the preliminary carrying part, they are sent between the separating roller 16a and separating piece constituting a document separating part, where they are separated one by one, and each is sent to the carrying roller 17a.

Title: Cloth feed mechanism of sewing machine
Inventor: HORI MASAYUKI
IPC: D05B27/02
Filed: 1990-07-19
Abstract: PURPOSE:To reduce the difference in feed per stroke between forward feed and backward feed by forming a feed arm supporting portion whose surface is in the form of a circle of a radius of curvature corresponding to the distance between the respective center axes of a stanchion and a connecting shaft, and providing the feed arm supporting portion in such a manner that the position where it is disposed is movable in its longitudinal direction. CONSTITUTION:A feed bar D on which a feed dog H is formed is supported to a horizontal feed arm 21 in such a manner as being movable in the vertical direction. The feed bar D is vertically displaced by a vertically driving mechanism for the feed bar D and is vertically displaced when the motion of the horizontal feed arm in its longitudinal direction is transmitted thereto. The feed bar D is not slanted but almost horizontal because of the roughly parallel movement of the horizontal feed arm 21 regardless of the oscillating position of a connecting shaft, so reducing the difference in feed per stroke between forward feed and backward feed. As the position where a feed arm supporting portion is shifted in the longitudinal direction of the feed arm, the roughly parallel movement of the horizontal feed arm is slightly changed so that the degree of slanting of the feed bar is slightly changed. The difference in feed per stroke is further reduced by the change in the degree of slanting of the feed bar.

Title: Device for detecting level of liquid surface
Inventor: TOYODA EIJI
IPC: G01F23/60
Filed: 1983-10-19
Abstract: PURPOSE:To measure the level of a liquid surface accurately with rapid response by detecting the passage and interruption of light by a float floating in liquid. CONSTITUTION:The float 29 consisting of a material interrupting the penetration of light is arranged inside a guide pipe 6 set up in a case 1 so as to be vertically moved in the guide pipe 6. When the level of the liquid surface is moved and reaches the upper or lower limit, an optical signal from the detection of the upper or lower limit is interrupted by the float 29 and the optical signal is erased from an optical fiber 27A or 27B. Therefore, a voltage signal S/A or S/B of an opto-electric converter 31A or 31B is reduced in accordance with the erase of the optical signal and the output signal of a comparator 32A or 32B is turned to ''0'' and the reach of the liquid surface level to the upper or lower limit is detected. Thus, the level of the liquid surface can be measured accurately with rapid response.
