Title: Delay circuit
Inventor: SHIMOTASHIRO MASAFUMI
IPC: H03H11/26
Filed: 1992-04-30
Abstract: PURPOSE:To provide the delay circuit employing a semiconductor element suitable for large scale integration in which a frequency characteristic and a delay time are made variable. CONSTITUTION:An emitter resistor (re) of transistors(TRs) Q1, Q2 depends on a current I0 of current sources I1, I2. A transfer function H(omega) and a delay time Td are decided by the resistance R of the emitter resistor (re), resistors R1, R2, R3, R4 and the capacitance of capacitors C1, C2, C3, C4. Through the circuit configuration above, since the resistance of the emitter resistor (re) varies with the current 10, the change of the transfer function H(omega), that is, the frequency characteristic and the delay time Td are attained and the temperature characteristic of the delay time Td is reduced by providing a temperature characteristic to the current 10.

Title: Initial setting method of change-over switch
Inventor: OGAKI HIROYUKI
IPC: H04B10/03
Filed: 1991-05-16
Abstract: PURPOSE:To decrease frequencies of the operation of a change-over switch and to make fast by initial-setting the change-over switch with the prescribed method and switching to the fast part of a preliminary optical transmission device at the time of generating the abnormality of the fast part of a present optical transmission device. CONSTITUTION:In the initial setting, a lower-most order switch 22 of a change- over switch 22 of present transmission devices 32 34 connects a slow part 2 of a its own device to the switch 22 of a higher order device and the switch 22 of other devices 32 and 33 connects the switch 22 at the lower order side to the switch 22 of the higher order device. Thus, when a fast part 12 of the device 34 becomes different and a switch 24 of a preliminary device 31 is changed over, a fast part 11 in place of the fast part 12 is used, and when the fast part 12 of the devices 32 and 33 becomes different and the switch 22 of its own device and a switch 21 of the device 31 are changed over, the fast part 11 is used in place of the fast part 12. Thus, by the small action of the change-over switch, the change-over can be made fast.

Title: Nonvolatile semiconductor storage device
Inventor: TERADA YASUSHI
IPC: G11C17/00
Filed: 1986-05-13
Abstract: PURPOSE:To obtain a memory cell which acts as an EEPROM and a DRAM with simple constitution without increasing the number of elements by providing a transistor that responds to the operation mode between the source of an EEPROM memory cell and the ground. CONSTITUTION:If a mode switching signal line 9 is turned to L and a control gate line 8 to H, an inversion layer is formed and a memory transistor 4 forming the EEPROM goes to on-state regardless of the information it has, but the transistor 5 connecting between the source of the transistor 4 and the ground turns off. Thus a capacitance is formed between the control gate of the transistor 4 and a drain where information signal charges are accumulated, to form a one transistor one capacitor DRAM together with a transfer gate transistor 3. Therefore, there is no need to provided an ERPROM circuit and a DRAM circuit. In such a way, the memory cell that acts as an EEPROM and a DRAM can be produced with simple constitution with the less number of elements.

Filed: 1988-05-10
Abstract: PURPOSE:To prevent the generation of cracks, and to remove the defective oxidation of a lead material by using the lead material having low-temperature softening properties as the lead material for a film carrier. CONSTITUTION:A copper foil and a lead material for a film carrier are composed of high-purity copper, a semi-softening temperature of which is brought to 140 deg.C or lower and purity of which is brought to 99.9wt.%. The semi-softening temperature of the lead material is limited at 140 deg.C or lower because load is increased when a lead exceeding 140 deg.C is pushed against a pad, cracks are generated in an Si chip and the lead material is oxidized and brought to a defective state because of the elevation of a heating temperature and is improper as the lead material for the carrier. The lead material has sufficient strength at the pre-stage of bonding and no defective on bending, etc., is generated, and an impact to the chip is reduced on bonding. Accordingly, the generation of cracks is prevented, and the defective oxidation of the lead material is removed.

Title: Attaching device of solid-state image pickup element
Inventor: OKIYAMA YOSHITATSU
IPC: H04N5/335
Filed: 1981-07-17
Abstract: PURPOSE:To prevent an optical position shift of a solid-state image pickup element, by fixing a substrate containing the image pickup element to a fixing stage and at the same time pressing the substrate to the fixing stage by means of a pressing means. CONSTITUTION:A substrate 12 is fixed to a fixing stage 11 by the screws 15 and 16, and at the same time a plate spring 13 presses the substrate 12 to the stage 11 with the restoring force of the spring 13 and through a projection part 13a. As a result, the flatness of the substrate 12 is well secured. When the external factors such as the temperature and humidity vary, the substrate 12 expands and contracts horizontally as shown by the arrows 17a and 17b or in the opposite direction centering on the attached position of the screw 15. Here nothing controls the expansion and contraction of the substrate 12, and the pressing force still exists. Thus the flatness of the substrate is kept with no change.

Filed: 1981-07-17
Abstract: PURPOSE:To enable to control the flow rate and the temperature of water supplied  from a mixing water tap and to change the direction of water supply through manipulation of a single lever, by combining a pair of valve mechanisms having a valve rod  respectively on the hot-water side and the cold-water side of the tap with a control shaft having a cams for co-operation with said valve rods. CONSTITUTION:A pair of valve rods 22, 22' are both urged by the force of a spring  from the back of respective valve bodies 36, so that they are forced into engagement  with cam surfaces 24, 24' of a control shaft 13. When the control shaft 13 is moved  upward by a lever 16, valve bodies 36 are retracted by the cam surface 24', so that hot  water and cold water are introduced into a mixing chamber 3 from valve ports 37, and  after they are mixed sufficiently in the mixing chamber 3, supplied to the outside via  a valve port 26' and an opening 30. On the other hand, if the control shaft 13 is moved downward by the lever 16, the valve bodies 36 are retracted in the same way. However, since the valve port 26' is closed by a valve 19, the water passage is changed  such that water in the mixing chamber 3 flows from a valve port 26 to a shower head.  Further, the temperature of water supplied from the tap can be controlled simply by turning the lever 16 to the right or left.
