Title: Ultrathin plate multiple mode filter
Inventor: ISHII OSAMU
IPC: H03H9/56
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To easily suppress spurious radiation without causing dispersion in the characteristic among devices by providing a spurious suppression electrode at a prescribed interval thereby surrounding electrodes. SOLUTION: Spurious suppression electrodes 10, 10 are formed so as to surround electrodes 4, 4 arranged to a plane side of a vibration section 2 at prescribed positions as soon as the electrodes 4, 4 are formed by the photoplithography method. In this case, the electrodes are not crossing the lead electrodes 6, 6. In the ultrathin plate crystal multiple mode filter with the spurious suppression electrodes 10, 10 formed thereto, spurious radiation at high pass band frequencies is remarkably suppressed, and one reason of suppressing spurious radiation is considered that bipolar charges caused by spurious radiation are cancelled by the spurious suppression electrodes to hardly cause vibration with the increased impedance against spurious radiation.

Title: Synchronizing circuit
Inventor: SUGAWARA MITSUTOSHI
IPC: H03K3/64
Filed: 1981-02-19
Abstract: PURPOSE:To form a synchronizing circuit of simple constitution by transistors (TR) integrated as analog one and a resistances. CONSTITUTION:The 1st signal is inputted to a T flip-flop 8 through a gate circuit 3. The TFF8 inverts an output signal at the rise of an input signal to a terminal T. The 2nd signal is inputted to a resetting circuit 7. When the 2nd signal is at an ''L'', TRs 13 and 14 both turn on to force the base potentials of TRs 82 and 83 to drop to the ''L''. As a result, only when the 2nd signal is at a level ''H'' and the 1st signal rises, an output which synchronizes with the 1st signal appears at an output terminal 6.

Title: Manufacture of semiconductor device
Inventor: KATO TERUO
IPC: H01L21/20
Filed: 1987-02-05
Abstract: PURPOSE:To obtain a crystalline layer proper for forming a device not doped in high concentration by shaping the crystalline layer in low-concentration doping onto an L-SPE layer in high-concentration doping formed onto an insulating film shaped onto a substrate. CONSTITUTION:When an Si film 13 is formed to the surface of an Si substrate 11 to which an silicon oxide (SiO2) film 12 (pattern) is shaped, the formed film is changed into polycrystalline Si on the SiO2 film 12 and into single crystal Si in other sections. Si ions are implanted to the film and the film is brought to an amorphous state, and an impurity is doped to the film. When the Si substrate 11 is lateral solid-phase epitaxy (L-SPE)-grown through heat treatment, a single crystal Si film 13a is acquired, and a position where separate from the end of the SiO2 film 12 at a distance larger than the film 13a is turned into a polycrystalline Si film l3b. When Si is grown onto the substrate in an epitaxial manner, Si evaporated onto said single crystal Si film 13a is converted into a single crystal Si film 14a and Si evaporated onto the polycrystalline Si film 13b into a polycrystalline Si film l4b. Accordingly, an Si layer in low concentration can be shaped onto an Si layer including the impurity in high concentration, thus forming a semiconductor device.

Title: Memory controller
Inventor: KUZUMI SHOSUKE
IPC: G06F12/02
Filed: 1994-01-26
Abstract: PURPOSE:To improve the utilizing efficiency of a high-speed access mode of DRAM. CONSTITUTION:First and second registers 12 and 13 hold line addresses at the times of accessing this and last times and a comparator 14 compares the contents of these so as to detect the change of a line address. Then, when a mode does not become a high-speed access mode though the line address does not change, a control circuit 17 increases the ON-time of a line address strobe signal 8. On the other hand, when the mode is the high-speed access mode though the line address changes, the ON-time of the line address strobe signal 8 is reduced. As the result, when the memory access of an application program is repeated with regard to the same line address, the high-speed access mode is kept long time and when the line addres changes frequently, the high- speed access mode is finished in a short time.
