Title: Semiconductor device and manufacture of the same
Inventor: HASEGAWA KIYOSHI
IPC: H01L23/28
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To avoid the occurrence of warpage in a semiconductor device, to improve flatness and to improve the mounting yield of the semiconductor device by manufacturing the semiconductor device by means of fixing prescribed warpage preventing resin on the other face of a double-faced substrate. SOLUTION: Even if an IC chip 43 which has multiple pins and whose chip size is small is mounted on an interposer substrate 41 whose size is large, the warpage preventing resin 47 formed of a material similar to that of sealing resin 46 along the periphery of the back 41B of the interposer substrate 41, and a chip size package(CSP) 40 is manufactured. When hear stress is given, the occurrence of warpage in CSP 40 can be avoided even if the coefficients of thermal expansion between the interposer substrate 41 and sealing resin 46 differ at the temperature of not less than a glass transfer point temperature. Thus, the long reliability of CSP 40 can be improved and the height of soldering o the interposer substrate 41 can be made uniform.

Title: Method for manufacturing positive electrode for lead storage battery
Inventor: MATSUBAYASHI SATOSHI
IPC: H01M4/57
Filed: 1982-10-29
Abstract: PURPOSE:To improve life characteristics in the charging and discharging cycles of a lead storage battery, by previously applying sulfate such as sodium sulfate to the grating and then applying paste on the sulfate coat. CONSTITUTION:Sulfate such as sodium sulfate or pottasium sulfate is previously applied to the grating and then paste is applied on the sulfate coat. By so doing, pH in the vicinity of the grating becomes higher than pH on the surface of the electrode plate at the time of chemical formation, and therefore, more alpha-PbO2 is formed in the vicinity of the grating. By the formation of the alpha-PbO2 having properties less reactive and not readily reacting there, formation of an oxide layer as a product due to reaction between the grating and the active material (beta-PbO2) is suppressed. Since the formation of the oxide layer between the grating and the active material due to repeated deep charging and discharging is thus suppressed, the improvement of the life characteristics of the battery is achieved.

Abstract: PURPOSE: To enhance insecticidal activity of insect-parasitic nematodes by concomitantly applying the nematodes and an insecticide and control pest insects of lawn grass in extremely effective manner under the suppression of bad effect of the remaining insecticide on the environment to the minimum level by using a smaller amount of the insecticide. CONSTITUTION: Pest insects of lawn grass (especially, larvae of June bug) are controlled by applying insect-parasitic nematodes (e.g. Steinernema or Heterorhabditis) and an insecticide (e.g. a carbamate, an organophosphate, an organohalide, a pyrethroid, a nereistoxin or an insect growth controlling-type insecticide) in combination. It is preferable to mix insect-parasitic nematodes with an insecticide directly before the application.

Title: Control device
Inventor: KUWABARA SHIGEHISA
IPC: H01H13/02
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To achieve both the enhancement of visibility by means of emission of light from entire controls and the thinning of a control device itself and to provide good controllability by forming the switch abutting part of an operating portion on the lower surface of approximately the center of the operating portion. SOLUTION: When the operating surface 21 of a specific operating portion 20 is pressed, a switch abutting part 221 causes a switch 41 to be deformed and moved downward against the elastic force of the switch to turn on a circuit. When the circuit is turned on, a LED 42 placed in proximity to the switch 41 is turned on to emit light upward, with the result that the light is focused and refracted at a recess 222 in the bottom surface 22 of the operating portion 20 as it is guided by the interior wall of a hole 54 in the expanded part 53 of an elastic sheet 50. Part of the light goes straight into the operating portion 20 and out of the operating surface 21, while another part of the light is reflected by an inclined surface 231, with the reflected light further reflected by an inclined surface 241 and allowed to go out of the operating surface 21.  Therefore the entire semitransparent operating portion 20 pressed is made to emit light almost uniformly at predetermined brightness, allowing the on state of the circuit to be visually checked.

Abstract: PURPOSE:To simplify an outside circuit for controlling a memory, to save a mounting space, and to reduce a cost by changing an interface with the outside of a refresh control. CONSTITUTION:A memory 8 incorporates a refresh(Rf) timer 4. When a time out signal 16 is generated from this in a constant cycle, an Rf requesting circuit 5 generates an Rf requesting signal 17 to the outside. When an Rf permitting signal 13 is inputted from the outside, an RAS.CAS generating circuit 1 supplies an Rf starting signal 14 to an Rf address counter 2, and activates the Rf. Then, the Rf of a memory cell 3 is executed by a memory cell controlling signal 15. The timer 4 and the circuit 5 are reset by the signal 13, and turned to be in a state waiting for the next Rf signal 16. And also, the signal lines of an RAS 11 and a CAS 12 and the signal lines of the signals 17 and 13 are separat ed, and set as different pins, so that an only bus controlling circuit 9 is enough for the outside circuit for controlling the Rf. Thus, a simple circuit constitution can be realized by both the circuit 9 and an RAS.CAS controlling circuit 7, and the cost can be reduced.
