Title: Element isolation by trench
Inventor: HATA SHIYUUGEN
IPC: H01L21/762
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a method for isolating elements by a trench in a semiconductor device by which element isolated areas having an improved profile can be formed. SOLUTION: A second material layer pattern 104B is formed on a substrate 100 wherein trenches are formed, and the second pattern 104B is undercut. Insulating material then is buried in the trenches. Therefore, when the trench buried material pattern 108A is partially etched in the case of wet etching which removed the second material layer pattern 104B and a first material layer pattern 102B, active areas are not exposed. Thereby a problem that active areas may be exposed owing to etching edges of the trench buried material pattern 108A can be protected. This enhances the profile of the edge of the element isolated areas. As result, this method enhances characteristics of semiconductor elements as the leakage current, etc., decreases.

Title: Intake/exhaust device for internal combustion engine
Inventor: HABU NOBUO
IPC: F02B75/00
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of knocking by forming an EGR gas layer over the whole circumference of the peripheral part of a combustion chamber. SOLUTION: Communicating passages 18, 19, 20, 21 are arranged in this intake/exhaust device so that intake ports 6, 7, 8, 9 of air cylinders 2, 3, 4, 5 in an intake stroke and exhaust ports 13, 12, 11, 10 of air cylinders 5, 4, 3, 2 in an exhaust stroke are communicated with each other, thereby exhaust having high exhaust pressure of the air cylinder in the exhaust stroke is supplied as EGR gas to the air cylinder in the intake stroke. The negative pressure of the intake port is large at the time of a light load and blow down pressure is large at the time of a high load, therefore differential pressure between the intake port of a predetermined air cylinder and the exhaust port of the air cylinder corresponding to the predetermined air cylinder is always large.  Therefore, EGR gas pressure can be sufficiently increased, and sufficiently strong intercylinder swirl can be produced in the combustion chamber of the air cylinder in the intake stroke.

Title: Switching type single-line communication equipment
Inventor: TAKEMURA YOSHIO
IPC: H04M11/06
Filed: 1988-03-07
Abstract: PURPOSE:To allow the private band of a telephone circuit to be half by providing a synchronous receiving part and a synchronous transmission part to be operated according to a synchronizing signal to indicate the timings of a transmission and a reception which is set to be two-fold or above that of the maximum frequency of a signal to be carried. CONSTITUTION:Signals outputted from synchronous receiving parts 12 and 22 are signals to be interrupted according to the frequency of the synchronizing signal, and the frequency of the synchronizing signal is set to be two-fold or above that of the maximum frequency of a signal band to be carried by a first carrier. Consequently, the signals to be interrupted are made into signals to contain all information of the information in the signal band, and the information to be carried is outputted from the synchronous receiving parts 12 and 22 without being lost. Since the information in the signal band is interrupted by the synchronizing signal, the transmission of the signal by a second carrier is made into the transmission of the signal to be interrupted, and for the same reason, all information can be transmitted without being lost. Thus, the private band of the telephone circuit can be made half.

Title: Production of tft-lcd
IPC: G02F1/1368
Filed: 1992-03-12
Abstract: PURPOSE:To provide the low-cost TFT-LCD having high reliability by shortening the process for production of the TFT-LCD. CONSTITUTION:An electrode material formed by a sputtering device is deposited on a glass substrate formed with the resist of a reversal mask and is thereafter patterned by a lift-off method. Then, the electrode material formed by the sputtering device is patterned by the lift-off method in this process for production and, therefore, a stage for etching metals is eliminated and since the photoresist is not subjected to an etching liquid for the metals, the peeling of the photoresist is easy. The number of steps of the production process for the TFTs is thereby shortened and, therefore, the low-cost TFT-LCD having the high reliability is obtd.

Title: Charging circuit
Inventor: MIMURA TAKEHIKO
IPC: H02J7/00
Filed: 1990-03-05
Abstract: PURPOSE:To make it recognizable that the secondary battery of portable information equipment has been exhausted by stopping the charging of the battery and issuing an alarm when it is detected that the voltage of the battery does not reach a normal level even when a prescribed period of time has elapsed after starting the charging of the battery. CONSTITUTION:When a reset circuit 13 is released after an AC adapter is set, the levels of the outputs OUTs 1 and 2 of a timer 14 respectively become high levels after 30 minutes and 15 hours. When a battery 11 is normal, the 'ABNORMAL' signal S0 and Q output of an FF 15 become low levels within 30 minutes and the 'WARNING' signal SW also becomes a low level. Regarding the output of a gate 16, the normal current during the 15 hours turns on transistors(Trs) 8 and 6, makes a resistance 4 to short circuit, and detects 3 a drop in potential difference, since the output OUT 2 of the timer 14 is inverted after 15 hours. A control circuit 2 sets a Tr 1 for trickle charge. When the battery 11 is defective, the signal S0 stays at the high level even after 30 minutes has elapsed and the signal SW becomes a high level, resulting in issuance of an alarm. Therefore, it can surely be detected that the battery has been exhausted.
