Title: Life test method for semiconductor device
Inventor: TAKAGI MIKIO
IPC: G01N17/00
Filed: 1978-12-28
Abstract: PURPOSE: To enable to perform the acceleration life test at desired high temperature, moisture and voltage and to avoid the problem of pollution, by using very simple unit consisting of quartz tube, stopper and water, etc.  
     CONSTITUTION: Silicon wafer 2 on the boat 3 is put in the quartz tube 1 and the vessel 4 having a given amount of water 5 is inserted. Further, the quartz stopper 6 is inserted in the quartz tube 1 and vacuum is made while heating the tube. The tube softened with heating is compressed with pressure reduction and molten with the quartz stopper 6 unifiedly. In this case, the water 5 in the vessel 4 is evaporated and the pressure in tube is increased. The pressure in tube is related to the temperature, and if the in-tube is under saturated vapor pressure, the temperature-vapor characteristics is as shown in the curve Ca in Fig. 2. If amount of water is insufficient and saturated vapor pressure is not reached, the characteristics is as shown in the curve Cb. By using the curve Cb, the silicon wafer 2 can be put under the life test at the desired temperature, pressure and the moisture determined with those.

Title: Resistor ladder type graphic equalizer
Inventor: YAMADA YUSUKE
IPC: H03K17/16
Filed: 1991-07-03
Abstract: PURPOSE:To suppress shock noise and to minimize a deviation in the gain by providing a resistor which keeps a potential at a start point of each resistor ladder section equal to an input potential of a noninverting input amplifier to the equalizer. CONSTITUTION:Potential latch resistors 8x, 8y are connected between analog switches 8a, 8b used to connect a resistor ladder section 7 to a noninverting input terminal or an inverting input terminal of a noninverting amplifier 3 at the input side to suppress a rapid potential change. That is, the resistors 8x, 8y whose resistance is 10KOMEGA are connected across the switches 8a, 8b. Then even in the mode where the switches 8a, 8b are opened, an input potential of the noninverting input amplifier 3 is fed to the resistance ladder section 7. Thus, no shock noise is caused due to rapid fluctuation of the potential at the noninverting input terminal and the inverting input terminal by the on/off of the switches 8a, 8b by means of the resistors 8a, 8b.

IPC: H04N1/32
Filed: 1994-07-15
Abstract: PURPOSE:To make possible facsimile reception by accepting a remote signal only for a certain time from a ring signal stops and making a judgement if an attached telephone set is in the on-hook state. CONSTITUTION:When ring signal detection stops before the ring signal is inputted as many times as specified, a control means 17 detects whether or not the attached telephone set 5 is in the off-hook state by a detecting means 9. When the telephone set is not placed in the off-hook state, it is considered that a directly connected telephone set 2 is placed in the off-hook state, a timer 16 clocks the time to detect the remote signal only for a certain time, and when the remote signal is present, it is detected by a detecting means 12 through a monitor means 8 and outputted to the means 17. When the remote signal is detected, a telephone line 1 is closed and a facsimile reception state is entered. When the off-hook state of the telephone set 5 is detected, the remote signal is detected until the telephone set 5 is placed in the on-hook state and the line 1 is closed in response to the presence of the remote signal, so that the equipment enters the facsimile reception state.

Title: Terminal device for battery and stroboscopic circuit
Inventor: HOSAKA TAKAO
IPC: H05B41/32
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain a terminal device for a battery capable of preventing imperfect contact in spite of simple constitution by providing a spherical terminal abutting on the negative pole of a battery. SOLUTION: A terminal for a negative pole 11 constituted by connecting two spheres 11a by a connection 11b is arranged on the right wall of a battery case C. The terminal 11 is connected to a stroboscopic circuit through a lead 11c. Even when the negative pole BM of the battery B is depressed, the sphere 11a of the terminal 11 surely abuts thereon. Since the contact area of the sphere 11a is the same regardless of an abutting direction, stable abutting is secured. Furthermore, the sphere 11a has little permanent set in fatigue even though it is used for a long time, and it is excellent in durability. It is good to use only one sphere 11a or also good to arrange three or more spheres at equal intervals in a circumferential direction. By making a gap D between spheres 11a larger than the diameter of the projecting part of the battery, it is used also as the terminal for a positive pole.

After that, HB is returned to the lower limit D (point B) and the read-out for all bits is made. In this case, driving magnetic field is produced with the driving current a, driving current b flows to the transfer gate 7 to obtain the output signal c from the detector 3. Thus, all the bit information of the minor loop 2 is transferred every one period of HB on the loop 1 by opening the gate 7 to enable to detect the signal c as the vortex bubble.
