Patent JP-H0520204-A (JP)
Title: Semiconductor device
Inventor: TANAKA YOSHIYUKI
IPC: G06F21/79
Filed: 1991-07-11
Abstract: PURPOSE:To protect the secrecy of data by utilizing one bit of a nonvolatile memory cell as an information source for inhibiting reading from a ROM. CONSTITUTION:The one-bit non-volatile memory 7 is a logical value '1' in an erasing state, and when a logical value '0' is written, a read inhibiting signal is activated a reading circuit 4 is not turned to a reading state independently of a reading circuit control signal 5, so that data can not be read out from a non-volatile memory cell group 1. When a reading coding circuit 10 exactly writes data for resetting reading inhibition in a non-volatile memory cell 8 consisting of several bits, the circuit 4 is driven by the circuit 5 and the data of the cell group 1 can be normally read out.

Title: Combustion mechanism utilizing aritifical tornado
Inventor: MATSUI SHIGEO
IPC: F23C7/02
Filed: 1987-07-10
Abstract: PURPOSE:To raise the effect of combustion by drawing the combustion flame in the state of a vortex through an artificial tornado generating mechanism. CONSTITUTION:When air is discharged into a cylindrical body 1 for combustion from an air discharge port 2, the air swirls along the internal side wall of the cylindrical body 1 for combustion, forming an artificial tornado H which stands between a burner 4 and an air suction pipe 3 with its bottom at the burner 4. The flame 5 which is burning from the burner 4 runs upwards in a vortex towards the air suction pipe 3 due to the artificial tornado H. Because in this case the flame 5 makes a long flame running upwards in the air section of the artificial tornado H, the time of combustion becomes longer and because at the same time the air converges to the central section along the whole length of the flame 5, enough oxygen is supplied to the flame 5. As a result it is possible to give complete combustion to the flame 5 from the burner 4.

Title: Manufacture of semiconductor device and bar code reader
Inventor: KIRISAKO TADASHI
IPC: H01L21/027
Filed: 1988-07-08
Abstract: PURPOSE:To make it possible to remove a film which is formed on a bar code pattern without complicating a manufacturing steps by exposing a resist film on a region where a bar code pattern is formed when bar codes are read, and thereafter developing the resist film. CONSTITUTION:An insulating film or a metal film is formed on a wafer 1 in a step after a bar code pattern 5 has been formed. A positive type resist film which is to become a mask for forming a pattern is formed on said layer. At this time, bar codes by which the wafer is recognized are read for the wafer 1 which is conveyed to a recognizing position on a bar code reader. At the same time, light from an exposure light source 15 is projected on a region where the bar code pattern 5 is formed. At this time, the light from the exposure light source 15 is projected only on the bar code region with a cover 17. The light is not projected on the other region. Since the part which has been exposed to light on the positive type resist film is dissolved with developing liquid, the surface of the insulating layer or the metal layer is exposed on the bar code region. Thus the wafer can be recognized without complicating steps.

Filed: 1990-06-29
Abstract: PURPOSE:To shorten useless waiting time of a caller data terminal equipment and to improve the processing efficiency by providing an incoming call rejecting signal monitoring circuit so as to always monitor the power supply state of the data terminal equipment, thereby immediately informing the connection fault to the caller data terminal equipment at the power interruption of a called data terminal equipment. CONSTITUTION:When a data terminal equipment makes a call to an exchange network, the call is sent to a line exchange 101. The line exchange 101 uses an incoming call rejecting signal monitoring circuit 103 to monitor an incoming rejecting signal 107 from the data terminal equipment 104. Since the data terminal equipment 104 is not energized, the incoming call rejecting signal monitoring circuit 103 informs the disabled communication of the data terminal equipment 104 to a line exchange section 102, which sends connection fault to the caller data terminal equipment. On the other hand, when power is applied to the data terminal equipment 104, the line exchange section 102 sends an incoming call signal to the data terminal equipment 104.

Title: Ultrasonic bonding method of thermoplastic resin member
Inventor: AWAZU NAOAKI
IPC: B29C65/00
Filed: 1981-10-29
Abstract: PURPOSE:To bond the thermoplastic resin members using an ultrasonic wave by a method wherein a plurality of projections are formed on the bonding surface of one of the  thermoplastic resin members and a plurality of grooves for allowing a fused part of  resin to flow thereinto are also formed on the same bonding surface, apart from a flash preventive gap formed between two members, so that the bonding strength of the  bonding section is increased. CONSTITUTION:In case where the thermoplastic resin members 1 and 1' (for example,  polyamide resin) are fusion bonded, the projections 3 are formed on the bonding surface of one of the members 1 and 1' while the grooves 5 extending parallel to the projections 3 are formed on both sides of each of the projections 3 and /or both sides of a  part of the surface at which each of the projections 3 comes into contact with the  bonding surface of the other member and the members 1 and 1' are bonded by ultrasonic wave to each other. EFFECT:When an ultrasonic wave transmitting phon signal is applied on the projections  3 through the member 1, the projections 3 and the surface of the member 1' with  which the projections 3 come into contact are softened and fused to flow into the  grooves 5 and to fill the clearance 4 between the members 1 and 1'. That is, the fused parts of the resin members flow into the grooves 5 and the bonding action progresses  as the projections 3 are removed so that the obstruction to ultrasonic energy due to  the fused resin parts does not take place.
