Title: Manufacture of lead frame and semiconductor device
Inventor: KUBOTA AKIHIRO
IPC: H01L23/50
Filed: 1982-01-18
Abstract: PURPOSE:To prevent corrosion by overall Ni-plating the surface of a lead frame. CONSTITUTION:A lead frame consists of a frame 1, mount 2 for a semiconductor chip, external terminals 3, coupling section 5 and wire bonding sections 6. The entire surface of the lead frame substrate is subjected to Ni-plating for the prevention of corrosion. Next, the mount 2 and wire bonding sections 6 are plated with Au or Ag, and the external terminals 3 with Sn or solder. Corrosion is prevented because Ni-plating prevents the material forming the lead frame substrate from exposure.

Title: Mirror mechanism of motor drive camera
Inventor: HASHIMOTO AKIHIKO
IPC: G03B19/12
Filed: 1979-01-22
Abstract: PURPOSE: To obviate the transmission of the revolving force of a motor to a mirror- driving gear by releasing the transmission force by the member which releases the transmission force of an interlocking mechanism during the time of shutter charging and film winding operation.  
     CONSTITUTION: A motor 16 which had been revolving counterclockwise is stopped by release operation and shutter operation is effected. When pinion gears 63, 64 are brought to the upper positions by clutch plates 26, 65 after the motor 16 has revolved clockwise, winding of shutter curtain is accomplished, thence the engagement of one end 22a of the release plate and engaging pawl 3a is released and film winding operation is accomplished. When the motor 16 is revolving clockwise, an intermediate gear 19 is revolved counterclockwise by a pinion gear 18 and therefore the gear 19 and drive gear 17 do not intermesh, hence the revolving force of the motor 16 is not transmitted to the mirror-driving gear 25 which is driven by way of the drive gear 17.

Abstract: PURPOSE:To realize effective use of a packet network, by holding the calling of a terminal to be called when the terminal to be called is busy, informing the state to a calling terminal, monitoring the end of communication of the terminal to be called and resetting the call after the end of communication. CONSTITUTION:When a calling request packet CR2 from a terminal T1 is received at a packet exchange PS3 during the communication between data terminals T2 and T3, the exchange PS3 transmits a busy display packet WT2 to a terminal T1 to invite that the terminal T2 is communicated with the other terminal and the call is to be waited for until the communication is finished and monitors the end of communication between the terminals T2 and T3. When the terminal T1 requires the connection of the communication link with the terminal T3 succeedingly, the line is made busy as it is. When the communication between the terminals T2 and T3 is finished and a restoration request packet CQ1 is transmitted, the exchange PS2 transmits a disconnection instruction packet and the communication link is released. Succeedingly the exchange PS2 transmits an incoming call packet CN2 to the terminal T3 with the packet CR2, allowing to attain the communication between the terminals T3 and T1.

Abstract: PURPOSE:To make the height of a terminal low by making the supporting structure of a molded section of a terminal for input and output to which a conductive wire is connected the cantilever supporting structure wherein the conductive wire is supported at only one end which is connected to the terminal for input and output. CONSTITUTION:A terminal for input and output 1, a circuit board for controlling 4, and an element for switching 6 are connected with aluminum wires 5. The connection of these elements are done by ultrasonic welding by using an automatic machine or manual machine.

The flat board is reverse-U-shaped, or letter-U-shaped for increasing the rigidity and the supporting shape of the molded section 5 of the terminal for input and output 1 is changed. By this method, the conductive wires can be connected stably at all times and thereby a module which has a high reliability and the stable life can be manufactured.

Title: Control of combustion at time of switching of hot blast stove
Inventor: NAKAMURA TATSUMI
IPC: C21B9/00
Filed: 1979-01-22
Abstract: PURPOSE: To prevent the fluctuation of calorific value at the time of switching by a method wherein the flow rate of mixed gas for combustion is gradually increased or decreased depending on response time set by the character of flow rate-regulating valves when a plurality of hot blast stoves attached to a blast furnace are switched from combustion to draft or from draft to combustion.  
     CONSTITUTION: Blast furnace gas (BFG) having low calorific value and converter gas (LDG) having high calorific value are mixed with liquefied natural gas (LNG) in a mixing chamber 2 to produce gas having appropriate calorific value which is then supplied to hot blast stoves HS1W3. When the hot blast stove HS1 is switched from draft to combustion and the hot blast stove HS2 is switched from combustion to draft, the calorie of the mixed gas is varied by the difference in the response time to switching of flow rate-regulating valves 14 for the mixed gas and flow rate- regulating valves 11W13 for BFG, LDG and LNG. An increase and decrease rate X of the mixed gas at the time of switching is determined by expression I. By the value obtained, the gas flow rate-regulating valves 12W14 are controlled to prevent the variation of the calorific value of the mixed gas. The imperfect combustion of the gas and the reduction in thermal efficiency can be prevented.

IPC: H04M3/26
Filed: 1981-01-21
Abstract: PURPOSE:To make a complicated testing device unnecessary to simplify the device, by adding the function for testing a trunk circuit and a subscriber's circuit to central control device. CONSTITUTION:A path 16 through which signals are transmitted and received is provided between a trunk circuit 5 and a subscriber's circuit 2, and the function which generates a control signal for the test to circuits 2 and 5 and the function which discriminates whether signals from circuits 2 and 5 are normal or not are added to a central control device 4 of an exchange 1. When the trunk circuit 5 is connected to the service line 15 on a basis of the command from the control device 4 and the hook-on/off detecting function of the subscriber's circuit 2 is normal, the circuit 2 detects the closing of the loop of the line 16 and reports it to the control device 4 with the form of a hook-off signal. In this case, since the hook-off signal is a correct signal, the pass is discriminated by the discriminating function of the control device 4, thus completing the test for the hook-on/off detecting function of the subscriber's circuit.
