Patent JP-H0699309-A (JP)
Title: Female screw rolling method
Inventor: UCHIUMI TORU
IPC: B23G7/00
Filed: 1992-09-21
Abstract: PURPOSE:To provide a rolling method for a female screw without threaded engagement failure and with good workability. CONSTITUTION:Metal screw material of which only one part, adjacent to an opening 1, is a small diameter part 3 having an inside diameter smaller than a predetermined hole size before threading, is used for a hole 2 before threading, a tap same as a conventional one is used, and a female screw is rolled in the same way as usual so as to manufacture a female screw. As the small diameter part 3 has enough metal to form a screw thread, a wide recessed part which is formed on the top part of the first screw thread adjacent to the opening and causes threaded engagement failure, is not formed so that an approximately complete screw thread is formed from the first screw thread. Therefore threaded engagement failure rarely occurs so as to perform engagement works smoothly.

Title: Speaker equipment having directivity
Inventor: OYABA TAKASHI
IPC: H04R1/26
Filed: 1989-09-29
Abstract: PURPOSE:To provide directivity at both high and low frequency range by arranging a tweeter in the middle of a full band speaker and supplying a signal to the full band speaker through a phase shift circuit and to the tweeter through a high pass filter circuit. CONSTITUTION:A signal is inputted to a full band speaker SP3 through a phase shift circuit 3. A signal is inputted to a tweeter SP4 through a high pass filter circuit 4 while its polarity is inverted. As a result, the phase frequency characteristic is matched for nearly all the band by selecting circuit components of the circuits 3, 4 properly. Thus, the smooth characteristic not causing any trough on the sound pressure frequency characteristic on the frequency axis is obtained. As a result, the narrow directivity is obtained based on the frequency decided by the interval between both speakers at a low frequency range and over a wide range up to the reproduction limit frequency at a high frequency range.

Title: Charge transfer device
Inventor: ISHIHAMA AKIRA
IPC: H01L29/762
Filed: 1990-09-21
Abstract: PURPOSE:To enhance a transfer efficiency and to make a change in an operating voltage extremely small by a method wherein a gate insulating film is constituted of a triple film by a silicon oxide film, a silicon nitride film and a silicon oxide film which have been formed on a silicon substrate. CONSTITUTION:For example, an N-type buried layer 9 for charge transfer use is formed on a P-type silicon substrate 1; and a silicon oxide film 2 is formed on it by a thermal oxidation operation. After that, a silicon nitride film 3 is formed and a silicon oxide film 4 is formed on it, both by a vapor phase growth method. Then, transfer electrodes 5, 7 are formed via an interlayer insulating film 6; and an interlayer insulating film 8 is formed on the transfer electrode 7. By this constitution, the film thickness of the silicon oxide film is not increased at the edge of the transfer electrodes 5, 7. Consequently, a potential barrier is not formed, and a transfer loss is not caused at a charge transfer operation. Even when a bias voltage is applied to a gate electrode, an electric current is limited by the silicon oxide film 4 and an electric charge is not accumulated at the interface between the silicon oxide films 2, 4 and the silicon nitride film 3. An operating voltage is not changed even when this device is used for many hours.
