IPC: G06K7/10
Filed: 1990-03-02
Abstract: PURPOSE:To prevent the degradation of reading precision by shading light from the outside by a light shading means while, at least, a barcode put on a commodity is read by a reading means. CONSTITUTION:The commodity 1 carried on a carrying passage 2 by a carrying means 20 goes into a tunnel 3, and at least, while the bar code 10 of the commodity 1 is red by the reading means 5, the light from the outside is shaded by a light shading means 8 at one, at least, of the ways in and out 30 of the tunnel 3, and light shading by the light shading means 8 is canceled. Thus, since the bar code 10 is read under a state that the light from the outside is shaded by the light shading means 8 at one, at least, of the ways in and out 30 of the tunnel 3, the degradation of the reading precision due to the influence of the light from the outside can be prevented.

Title: Screening method of semiconductor laser diode
Inventor: WAKITA KOUICHI
IPC: H01L21/66
Filed: 1979-05-01
Abstract: PURPOSE:To remove the reflecting surface deteriorated of a semiconductor laser diode simply without rupture for short time by irradiating opaque emitting wavelength light externally to the active layer of the diode. CONSTITUTION:An AlGaAs-GaAs series double hetero junction laser is employed as a semiconductor laser diode, an Ar laser light is focused in intensity of 0.5kw/cm<2> by a lense and irradiated to the active layer 4 of a specimen 10 to measure the absorption current Ip by an ammeter 9 connected both terminals of the diode 10. The GaAs has very large absorption coefficient such as approx. 10<5>cm<-1> for the wavelength of the Ar laser. Since almost all light is absorbed within the vicinity of 0.1mum of the vicinity from the surface, the absorption current sensitively reflects the state in the vicinity of the reflecting surface. The lower the value of the current Ip, the faster the deterioration becomes. This is similar to the different wafer. Therefore, the screening of the semiconductor laser diode is conducted according to the value of the current Ip.

Title: Method for manufacturing semiconductor device
Inventor: ONO TOSHIAKI
IPC: H01L21/332
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To form a device of a high breakdown voltage and a low resistance by a method wherein an element circumferential part is designed in terms of impurity concentration and the thickness of a substrate, and the inside of the element is constituted so as to reduce a current path length. SOLUTION: With a mask used as an oxide film, P-type impurities are diffused in a stripe shape in a recess part 7 of a low concentration layer 6 and on the entire surface of an outer peripheral part of the surface of the low concentration layer 6 to form P<+> layers 8, 9, and a gate electrode-forming opening part is formed on a surface of an N layer 10 formed on the low concentration layer 6 and the P<+> layers 8, 9 on a silicon layer, and then a part of the N layer 10 becomes a source layer 11. The P-type impurities are diffused to form a P<+> layer 12, and a N<+> ohmic layer 13 is diffused on the surface of a part of the source layer 11 to make an electrode metallization to form a source electrode 15, a gate electrode 16 and a drain electrode 17, and then the thickness of each diffused layer is increased by heat treatment in the process.  Accordingly, as internal resistance is decided mainly by a thickness of an N substrate of an active region, and a current path length is reduced, low resistance can be attained in the same breakdown voltage as in the prior art.

Abstract: PROBLEM TO BE SOLVED: To unnecessitate the recognition of an entry method, etc., one by one by means of an operation manual and to improve convenience in use by obtaining the optimum description position of telephone number information to be automatically recognized in an original from an equipment itself. SOLUTION: When a power source is turned-on, CPU executes initialization in a step S1 and also checks the operations of respective keys of an operation pannel. In the step S107, it is judged whether or not a hand-written key on the operation pannel is operated. After it is judged that the hand-written key is operated, CPU executes a processing in the step S108. That is, it is judged whether an automatic recognizing flag RF is '0' or not. When it is Judged to be '0', CPU judges whether an entry guide flag GF is '1' or not and immediately return the processing to the step S101 unless it is '1'. In the meantime, when GF is '1', the entry guide is printed in the step S184.

IPC: B29C45/02
Filed: 1982-03-31
Abstract: PURPOSE:To prevent the go-round of a resin material for forming a die to the open frame end of the lead frame of a drag, and to improve yield on the manufacture of a semiconductor IC by forming the hold-down section of the open frame end in a floating block mechanism. CONSTITUTION:A groove 17 is formed to the hold-down section II of the open frame end of the drag in approximately rectangular direction to leads 2 and so as to extend while exceeding the width of the open frame end of the lead frame, and a floating block 19 is supported by a spring 18 disposed to the bottom. The floating block 19 is of a metallic material of a rectangular parallelepiped lengthening extending over the full length of the groove 17. According to such constitution, the go-round of the resin material is prevented because the upper surface of the floating block 19 is brought into contact with the lower surface of a cope at all times by the spring 18 even when a hold-down clearance of the lead frame is taken and there is variance in the plate thickness of the lead frame. Such floating mechanisms are formed to all of the hold-down sections of the open frames of the drag.
