Title: Plastic container
Inventor: MORI SHIGEKI
IPC: B29C51/08
Filed: 1990-03-12
Abstract: PURPOSE:To prevent injury of appearance due to deformation by a method wherein an upper part of a container body on an open end side is molded in a substantially oblong cylinder having a prescribed height with respect to the entire height of the container without vertical ribs, a lower part of the container body is molded in a shape the cross section of which is a substantially right polygon consisting of a plurality of vertical ribs and panel faces between the ribs, and the respective ribs are formed to be thicker than the panel faces. CONSTITUTION:In a plastic container, a lower body part has a cross section of a right polygon, the container 1 consists of a body 2 and a bottom part 3, and the body 2 consists of an upper body part 4 shaped in a substantial cylinder and the lower body part 4 shaped in a right octagon. The height (h) of the substantially cylindrical upper body part 4 is set to one third or less of the entire height (H) of the container 1, because if the height (h) is too high with respect to the entire height (H), the length of a varietal rib 10 becomes too short to retain the strength of the container 1. If the number of the vertical ribs 10 is increased, the strength against load from the lateral direction of the container 1 cannot be retained, and therefore it is preferable to set the number of the ribs 10 to a dozen or less. On the contrary, if the number of the vertical ribs 10 is too small, the strength against the load from the vertical direction of the container 1 cannot be retained and the container 1 is likely to deform inward or outward, and therefore it is preferable to set the number of the ribs 10 to half of dozen or more.

Title: Array type piezoelectric converter
Inventor: UMEMURA SHINICHIRO
IPC: G01N29/24
Filed: 1991-03-22
Abstract: PURPOSE:To realize excellent resolution in the direction of a short axis while maintaining an enough focal depth by controlling the effective area of the electrode of a piezoelectric element. CONSTITUTION:The effective area of the electrode of piezoelectric elements 1-1 to 1-N is weighted by making the area projected in the direction of a long axis per the unit length in the short axis direction large at the center part of an opening and making it smaller toward the end part. By such weighting in the short axis direction, the transmission sound pressure and receiving sensitivity of an ultrasonic wave in the short axis direction can be made large at the center part of the opening and made smaller toward the end part. At this time, a repetitive pitch in the long axis direction of the shape of the electrode is set below a half wave length. Thus, the formation of grating lobe caused by the weighting in the short axis direction can be prevented.

IPC: H03H17/02
Filed: 1988-03-11
Abstract: PURPOSE:To ensure a stabilized dynamic holding state by sending serially the data on a shift register of the preceding stage to a shift register of the next stage in a shift register block at delay of the signal and otherwise circulating the data on a shift register of its own stage. CONSTITUTION:The data and the enable signal are applied to a serial data input terminal 3 and a switch signal input terminal 4 respectively. The data received via the terminal 3 are serially sent to a dynamic shift register of the first stage as long as the enable signal is kept at a high level. At the same time, those data held by each dynamic shift register are transferred to the dynamic shift register of the next stage and also sent to an arithmetic block 24 via a data output terminal. Thus the data on the dynamic shift registers are held stably even with a long data holding cycle. Furthermore the chip area is not virtually increased despite the increase of the number of stages of the shift registers.
