Title: Mold for sealing semiconductor with resin
Inventor: MIYAMOTO MITSUGI
IPC: B29B7/00
Filed: 1982-08-18
Abstract: PURPOSE:To seal a semiconductor with resin of high quality containing no void and high moisture resistance by providing a resin reservoir in a mold. CONSTITUTION:A resin reservoir gate 14 is opposed to a gate 12 in a cavity 11 in the lower mold of separable molds and formed to communicate at the other end with a resin reservoir 15.

Title: Microwave filter
Inventor: SAKA HIROSHI
IPC: H01P1/203
Filed: 1990-05-31
Abstract: PURPOSE:To obtain a band stop filter characteristic at an image signal frequency by selecting the length of thee end open stubs connected in parallel to three positions of a main line at an equal interval to be almost 1/4 wavelength with respect to the frequency of the image signal, and selecting the length of the innermost stub to be longest. CONSTITUTION:End open stubs 13-15 whose length is respectively l1-l3 are connected in parallel with a main line 12 tying an input terminal 10 and an output terminal 11 for a high frequency signal at an equal interval l0. The lengths l1-l3 are selected respectively to be almost 1/4 wavelength with respect to a frequency of an image signal so that an attenuation pole comes in the band or in the vicinity of the band of the image signal. Then the lengths l1-l3 and the interval l0 are selected respectively to satisfy the condition of l2/4<l0<l1<l2 and l2/4<l0<l3<l2 or l2/4<l0<l1=l3<l2. Thus, the dimension and the insertion loss at a high frequency signal are reduced, the image signal is suppressed and the high frequency signal is passed without loss.

Title: Sheet-material treating apparatus
Inventor: MATSUO KAZUHIRO
IPC: B65H39/11
Filed: 1984-07-10
Abstract: PURPOSE:To permit a large amount of sheet material to be accommodated and loaded in non-collation by shifting a tray to the position lowered at least by one shift in non-collation in comparison with in collation. CONSTITUTION:A tray 41 is used in common as the tray used in non-collation and as the first tray used in collation, and since the much more sheet material is accommodated and loaded in non-collation in comparison with in collation, the sheet material transported from transport rollers 3a and 3b is accommodated at the position lowered by one shift than the position of the tray 41 in collation. While, in collation, tray group 41, 42... are lowered by the reverse revolution of a motor 10, and when the sheet receiving port of the uppermost tray 41 is opposed to the nipping parts of the transport rollers 3a and 3b, this fact is detected, and the motor stops. When the sheet is accommodated into the tray 41, a detection lever 14 and a detection sensor 22 detect said accommodation, and the tray 41 is raised, and the succeeding trays 42 are raised successively similarly.

Title: Disk driver
Inventor: SATO KEIICHI
IPC: G11B17/04
Filed: 1988-06-13
Abstract: PURPOSE:To decelerate the rejecting speed of a cartridge and to prevent the cartridge from being jumped out by providing a jumping-out preventing member in contact with the cartridge in the case of rejecting the cartridge. CONSTITUTION:As soon as a magnetic disk cartridge 17 accommodated in a cartridge holder 8 is lifted up to the eject position in the ejecting, a lock part is removed from a cam of a slide plate and the lock plate is made movable. Then the tip of the cartridge 17 is pressed by a press contact part 16 of the eject lever 13 to eject the cartridge from the cartridge holder 18. In case of ejecting, since a contact part 30 of a guide member 21 is pressed into contact onto the upper face of the cartridge 17 by the energy of a torsional coil spring 25, a friction resistive force is exerted to the cartridge 17 to weaken the ejecting speed thereby preventing the cartridge 17 from being jumped out of the cartridge holder 8.

Title: Measuring apparatus for flow rate for liquid chromatograph
Inventor: KASAI MASANOBU
IPC: G01F1/00
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a measuring apparatus by which the absolute value of the flow rate of a liquid can be always measured by a method wherein a change in the height of the level of the liquid in a reservoir is measured and the flow rate of the liquid which flows into, and flows out from, the reservoir is found on the basis of the amount of the change per unit time and on the basis of the volume of the reservoir. SOLUTION: When a liquid is guided to a reservoir 1, the time in which its level is passed between a sensor 4 and a sensor 5 is measured by using a light source 2 and a light source 3 and by using the sensors 4, 5. The flow rate of the liquid which flows into the reservoir 1 is found on the basis of the height difference between the sensors 4, 5 and on the basis of the cross-sectional area of the reservoir 1. Inversely, the liquid is stored in advance in the reservoir 1 until its level is detected by the sensor 4. The liquid is made to flow out in a state that the inflow of the liquid is stopped. The time elapsed until its level is detected by the sensor 5 is measured, and the flow rate of the liquid which flows out from the reservoir 1 is found. A clocking function in this case is born by a CPU.  By this method, even when the physical-propery value of the liquid is different, the absolute flow rate of the liquid flowing inside a flow passage can be measured without being affected by it.

Title: Adjusting method for shift error on weighing apparatus
Inventor: SHIMADA YOSHIAKI
IPC: G01G3/142
Filed: 1979-11-06
Abstract: PURPOSE: To permit the shift error on a weighing apparatus to be speedily adjusted by changing the variation tendencies of the resistance values of the first and second variable resistors to the same direction for each load cell in order to compensate the variation of the zero point, the first and second variable resistors being inserted between an exciting power and one power input terminal of each load cell and between the exciting power and the other power input terminal respectively.  
     CONSTITUTION: One balance test weight of a track scale is successively loaded on corners IWIV of a track mounting table C to check the parallel sum output VOUT. From the deviation between said parallel sum output and the output obtained when the weight is loaded on the center V, a load cell to be adjusted is decided. The variation tendencies of the resistance values of the first and second variable resistors VR 11  and VR 12  of, e.g., a load cell LC 1  decided by said operation are changed to the same direction to compensate said error. Such an operation is repeated until there is no deviation when the weight is loaded on any one of the four corners, to adjust the mutual relation between the load cells.
