Title: Erroneous reading prevention device in bar code reader
Inventor: TSUTSUMOTO KOUJI
IPC: G06K7/10
Filed: 1989-06-22
Abstract: PURPOSE:To surely prevent erroneous reading even when a defective spot exists on a bar code by providing plural read sensors provided in parallel along the direction of length of a bar element, and a judging means to decide a read signal according to prescribed majority logic based on the read output of each read sensor. CONSTITUTION:When the defective spot such as dust with different reflectance from that of a space element exists at a position corresponding to a reading locus on the space element, a large number of read sensors out of the read sensors S1-Sn read the white of the space element and output read data representing the white. Also, it happens that a few number of read sensors read the defective spot and output the read data representing black. The judging means 8 judges that the read data of the white is a true bar code element read data by a large number of read sensors S1-Sn according to the prescribed majority logic, and also, that the read data of the black is defective spot read data by a few number of read sensors. Thereby, the erroneous reading of the bar code can be prevented.

IPC: C04B35/638
Filed: 1989-06-21
Abstract: PURPOSE:To obtain the powder compact excellent in degreasing property and workability and without deforming a sintered body even when the compact is embedded in a fibrous inorg. material and sintered by using a fibrous inorg. material as a degreasing material in the compact consisting of a ceramic, metal powder and an org. binder. CONSTITUTION:An org. binder is added to the ceramic and metal powder, the mixture is formed into a powder compact, and the binder is then removed from the compact to produce the powder compact. In this case, the powder compact is embedded in a fibrous inorg. material and heated to remove the org. binder from the compact. The fibrous inorg. material used as above can be more easily handled in the process than the powder. Furthermore, when the compact is degreased and then sintered, the fibrous material is deformed in follow-up to the contraction of the compact in sintering, and the compact is perfectly held.

Abstract: PURPOSE: To obtain a navigation apparatus by which a road to be selected at a crossing can be known easily even during a driving operation by a method wherein, when the position of a vehicle is judged to have approached a prescribed distance from the crossing on the basis of the position of the vehicle and on the basis of map data, the enlarged figure of the crossing is indicated. CONSTITUTION: On the basis of the position of a vehicle by a positioning means 1 and on the basis of a drive route by a route-setting storage means 6, a control means 8 judges that a vehicle has reached a part before a crossing in which the vehicle changes its advance direction. Then, the control means detects a first crossing on the basis of map data, and, in succession, it investigates whether a second crossing in which the advance direction is to be changed exists or not. When it is judged that the crossing is not continued, an enlarged- figure creation means 7 creates a more enlarged figure than image data on the basis of the image data on a crossing stored in a data storage means 2, and the enlarged figure is outputted to an image display means 3.  When it is judged that the crossing is continued, the means 7 creates respective enlarged figures in order to simultaneously display two continued crossings, and the enlarged figures are outputted to the means 3.

Title: Non-magnetic substrate for magnetic head
Inventor: ITO EIJI
IPC: C01G51/00
Filed: 1989-06-23
Abstract: PURPOSE:To obtain the characteristics of both a thermal expansion coefficient and hardness approximately equal to a magnetic film structure by composing mixed ceramics of MgO and CaO at specific mol% or less and CoxNi2-xO2 as the remainder and forming the mixed ceramics in rock salt type structure in the mixed ceramics having a composition consisting of MgO, CaO, CoO and NiO in the non-magnetic substrate for a non-magnetic magnetic head for evaporating a metallic magnetic film. CONSTITUTION:A composition in which each of MgO and CaO is contained at 30mol% or less is employed while CoxNi2-xO2 (where 0.2<=x<=1.8) is used as a basic composition. Both MgO and CaO are substances having a sintering promotion effect, and the hardness is increased. Both thermal expansion coefficients of these substances of 30% or more are not desirable because the thermal expansion coefficients are lowered remarkably and segregation is generated and density is reduced. A dense sintered body having rock salt type structure is acquired through a powder metallurgical technique while using each oxide as raw materials.
