Title: Interruption control system for facsimile equipment
Inventor: TEZUKA YOSHIAKI
IPC: H04N1/32
Filed: 1992-10-15
Abstract: PURPOSE:To attain quick correspondence by informing a number of its own equipment and a reason of interruption to a destination terminal equipment when the communication is interrupted without sending picture information and displaying and recording the reason at a called equipment. CONSTITUTION:A DIS discrimination means 21 analyzes a received DIS signal to check whether or not the reception capability is enough and whether or not the transmission capability is enough when polling is commanded and starts a TSI signal (transmission terminal equipment identification) signal generating means 22 when both are not compatible, that is, the communication is discriminated to be disable. The means 22 generates a TSI signal based on a TSI signal format. The TSI signal is a transmission terminal equipment identification signal and the transmission terminal equipment is indicated by the international telephone number. A TSI signal transmission means 23 sends the TSI signal generated by the means 22 to a destination terminal equipment. When the picture information is not sent but interrupted, since the destination number and the reason of interruption are recognized at a called party, the called party takes countermeasures such as fault recovery or contact with the opposite party.

Title: Disk device
Inventor: YOKOUCHI HIDEYA
IPC: G11B19/22
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain a device for preventing the hooking between a spindle, driving pin and a disk, shutter by controlling the stop timing of the spindle while synchronizing to an index signal. SOLUTION: The highest part of the spindle 101 is at right angle with the disk inserting direction. Since the vertical dimension 113 of the spindle 101 can be lowered against the highest part of the spindle 101, the spindle 101 does not hit on the vertical part even though the disk 4 is brought into contact with the spindle 101. The disk is lifted up along a slope of the spindle 101 and prevented from hooking with the vertical part 113 of the spindle 101. Also at the time of ejecting the disk 4, similarly, the shutter 6 does not engage with the vertical part 113 of the spindle 101, and the disk 4 is ejected without hooking. Even though the shutter 6 is hooked with the driving pin 103, the disk is ejected without problem, because the spindle 101 is rotated by the ejecting force and the engagement with the driving pin 103 is released.

Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To provide such a film forming device with which the film forming rate can be easily determined according to arbitrary conditions of film forming to device the film forming time and the conditions of film forming can be freely changed. SOLUTION: The reaction gas is supplied to a reaction chamber 13 at specified pressure and high frequency voltage is applied between electrodes 11 to generate glow discharge. Thereby, a desired film can be formed on a substrate at a specified film forming rate. The film forming rate changes when conditions of film forming (such as the flow rate of gas, pressure and electric power) are changed. In this method, by inputting the film forming conditions and the film thickness, the film forming rate according to the database 15 is outputted based on the film forming conditions. Then the film forming time is calculated based on the film forming rate and the film thickness inputted. The high frequency voltage is applied from a high frequency power supply 12 on the electrodes 11 for the film forming time thus determined.  Therefore, a CVD film of desired film thickness can be produced and conditions for the process can be easily changed.

Title: Ferritic heat-resisting stainless steel excellent in weldability and workability in weld zone
Inventor: MIYAZAKI ATSUSHI
IPC: C22C38/00
Filed: 1986-12-18
Abstract: PURPOSE:To improve the ductility, formability, and toughness in a weld zone against wide range of welding conditions, by specifying the components and compositional balance of a ferritic stainless steel. CONSTITUTION:The ferritic stainless steel has a composition which consists of, by weight, <=0.025% C, <=0.8% Si, <=0.8% Mn, 9-17% Cr, <=0.6% Ni, <=0.75% Ti, <=0.025% N, <=0.15% Al, and the balance Fe and in which the relationship between N and Ti is regulated so that it satisfies inequality I and further respective contents of Cr, Si, Ti, C, N, and Mn are regulated so that they satisfy the relations in inequality II. In this steel, it is desirable that C and N contents are as low as possible because C and N cause deterioration in toughness in the weld zone, and, though the above adverse effect can be counteracted by the addition of Ti, toughness in the weld zone and base metal is deteriorated when C and N contents exceed the upper limits. Si content is regulated so that it does not exceed the upper limit in order to satisfy the toughness in the weld zone. Ti improves the workability of the base metal, but the toughness in the weld zone is deteriorated when Ti content exceeds the upper limit. Though Al has a function of securing the yield of Ti addition, deformation of parts is caused and toughness after use is deteriorated when its content exceeds the upper limit.

Title: Ac rectangular wave power source for welding
Inventor: TANIMOTO JUNZO
IPC: B23K9/073
Filed: 1987-11-30
Abstract: PURPOSE:To provide an AC rectangular wave power source for welding with high reliability by a simple circuit by converting the output of a transformer stepped down from the high-frequency voltage into the AC rectangular wave voltage by using a reactor and a control rectifying device and changing a duty ratio of the control rectifying device. CONSTITUTION:The DC voltage rectified by a rectifier circuit 7 and a smoothing circuit 8 is inputted to an inverter circuit 9 and converted into the high-frequency AC voltage. Frequency of an inverter is set by a frequency setting circuit 10 and the high-frequency AC voltage is reduced to the voltage to fit for welding by the transformer 11. The AC voltage is converted into the rectangular wave voltage by a conversion circuit 13 combining the control rectifying device 17 with the reactor 18 and impressed on a torch 6 and an arc 15 is generated to perform welding. A duty setting circuit 12 changes the duty ratio of Ia to Ib of an arc current waveform and controls penetration to base metal. By this method, AC rectangular waves are obtained by the simple circuit combining the control rectifying device and the reactor and since the control rectifying device has the excess flow resistant quantity, the reliability with respect to output short-circuit trouble, etc., can be improved.

Title: Module for optical communication, and its manufacture
Inventor: SUDO RYOICHI
IPC: G02B6/42
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To perform quickly the temporary stickings of fine parts on each other, by protecting or sticking directly or indirectly optical elements on a board through a resin with both photo-curing and thermosetting qualities. SOLUTION: By the thermal diffusion of a Ti based material, a photodetector 2a is disposed on an Si board 1a with a light waveguide 3a to attach an electric terminal 7 to it via an electric wiring 6. For the purpose of the protections of the portions of both the photodetection 2a and light waveguide 3a, a cover 9a comprising, e.g. such a small-sized cap as an alumina cap whereto an adhesive agent 10a is applied previously is stuck on the Si board 1a to cure the sticking agent 10a under the predetermined condition, applying to it a pressure of about 1kg. While the adhesive agents of a photo-curing type resin in the shaded portions by the small-sized cap are left uncured, since a thermosetting type resin is mixed with it, they are cured by its heating to obtain their desired adhesive strengths. Therefore, the temporary fixings of the fine parts on each other (both the cover 9 of the small-sized cap on the board 1a and the 2a on the board 1a) can be performed quickly.
