Title: Bubble imaging apparatus by means of ultrasonic wave
Inventor: TAKEISHI MASAYUKI
IPC: G21C17/038
Filed: 1992-04-09
Abstract: PURPOSE:To quickly collect bubble information in a tube or a vessel, simplify and downsize facility and measuring parts, eliminate need of constructing the tube of a specific material and reduce constructing and operating costs. CONSTITUTION:An ultrasonic beam is oscillated from a plurality of transmitting/ receiving transducers 1 provided along a circumferential direction around a pipe 2 or the like toward bubbles 4 in liquid 3 flowing inside the pipe, and the ultrasonic beam reflected against the bubbles 4 is received. This is sent to signal processors 352 to 359, where it is imaged with consideration taken to propagation characteristics of the ultrasonic beam such as transmission/ reception intensity, whereby bubble information in the pipe or a vessel can be quickly collected. In addition since X-rays or gamma-rays are not used for detecting the bubbles in the pipe, facility and measuring parts are simplified and downsized, there is no need to construct the pipe of a specific material and furthermore constructing and operating costs can be reduced.

Inventor: UMEDA TAKUYA
IPC: H04N5/372
Filed: 1995-04-14
Abstract: PURPOSE: To prevent lowering of photosensitivity due to fining of an element and realize high transfer efficiency by forming a structure in which a p-type isolation region between photodiodes protrudes into an n-type impurity well of a CCD channel by a specified depth. CONSTITUTION: A semiconductor manufacturing mask for p-type isolation region formation between photodiodes of a solid-state image pickup device of a usual technique is modified. That is, boron is injected at an acceleration energy of 30 to 100keV and a dose amount of 3×10<11> to 3×10<12> /cm<2> to a position of 0.3 to 0.7μm from a CCD channel n-type well formation mask. As a result a p-type isolation region 10 between photodiodes projects 0 to 0.2μm into a CCD channel n-type well 11. Thereby, it is possible to restrain trap of signal charges at an isolation part cross section position generated during charge transfer and to realize high transfer efficiency.

Title: Power-supply apparatus for vehicle
Inventor: KOZUKA AKIRA
IPC: H02M7/48
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce a starting current to a load and to suppress a transient increase in an output corrent by a method wherein, when a starting command to the load is input, so that an inverter is controlled in such a way that the output voltage of the inverter is made lower than a rated voltage for a prescribed time and a contactor is charged. SOLUTION: DC electric powder which is received by a pantograph 1 charges a filter capacitor 2 is converted into a desired AC electric power by an inverter 3. The output of the inverter 3 is supplied to a load 5 via a contactor 4. A control device 6 controls the contact 4 so as to be charged and released, and it controls the inverter 3. When a starting command 8 is input, the control device 6 controls the output voltage of the inverter 3, so as to be lowered for only a definite time. Then, when the output voltage is stabilized at a voltage which is lower than a rated voltage, the contactor 4 is controlled to be charged. Consequently, since the starting current of the load 5 is proportional to an applied voltage, the starting current of the load 5 in this case can be suppressed more than that in a case in which the load is charged at a rated output voltage.

Filed: 1979-07-13
Abstract: PURPOSE:To prevent a core from falling and floating and decrease the variance in the thickness of products by plunging a pin from the outside of a mold toward the core print part of the core inside thereby fixing the core. CONSTITUTION:When a stationary die 5 is emptied and a core fixing pin 1 is pulled upward, a spring 3 contracts and in this state, a core 7 is put in the stationary die 5. If the core fixing pin 1 is released after this, the tip of the core fixing pin 1 is plunged into the core print part of the core 7 by the force of the spring 3, by which the core 7 is fixed to the stationary die 5. Thence, if a movable die 6 is opposedly fixed to the stationary die 5 and molten metal is poured as specified, the molten metal runs to a product cavity 8, whereby the casting is obtained.

Title: Time expanded video signal generator
Inventor: SHIRATO SHINICHI
IPC: G06T3/40
Filed: 1988-04-13
Abstract: PURPOSE: To obtain a time-extended video signal without any noise by conditioning a memory means for storing M samples expressing one field of a video signal, and reading N samples in the stored samples. CONSTITUTION: M samples expressing one field of a video signal are written in a memory 16 for sample data in a first time period under the control of a memory writing address signal generating circuit 20. N samples in the stored M samples are read from the memory under the control of a memory reading address signal generating circuit 22 in a second time period. The second time period is offset for the first time period, and the N samples read from the memory in the second time period express the information of one field of the video signal. A circuit connected with the memory of the sample data processes the N samples supplied from the memory, and generates the M samples of a time-extended video signal. Thus, it is possible to prevent any distortion generated when a picture includes movement between fields by the extension.
