Title: Tube expander
Inventor: URAGAMI KOUICHI
IPC: B21D39/08
Filed: 1978-03-06
Abstract: PURPOSE: To prevent the O-ring from the break to be caused when the O-ring plunges into the clearance generated from the deformation or the movement of the backup ring, by forming a ring type projection on the outer surface of the mandrel, and by setting the backup ring between this ring type projection and the O-ring.  
     CONSTITUTION: The tube 2 is inserted into the hole 1a provided in the tube plate 1, and the mandrel 3 is inserted into the tube 2 so as to be expandable the specified position; the htdraulic medium like as water or oil is introduced through the hydraulic path 6 into the space formed by the O-ring 5, the tube 2 and the mandrel 3. Hereby, the tube 2 expands outside depending on the pressure being sealed by the O-ring 5, and at the same time, the backup ring 4 is compressed by the axial pressure component, and swells toward the outside diameter, and occupies the clearance formed between the backup ring 4 and the tube 2. As a result, the break of the O- ring 5, usually caused when the O-ring 5 plunges into above stated clearance, is greatly prevented. Besides, the backup ring 4 effects a supplementary expanding work against the tube 2, and makes mild the deforming gradient at the end zone of the expanded portion; hereby, the residual stress is greatly reduced.

IPC: G03B27/52
Filed: 1987-02-04
Abstract: PURPOSE:To eliminate defects due to heat generation of a LED array part to correctly form a toner image by exposing only the LED array part of an optical information irradiator to an air current to cool the LED array. CONSTITUTION:A LED array 5 of an optical information irradiator 7 is covered with a cover 20 for air blast. Air is sent to the space, which is formed by covering the LED array 5 with the cover 20, from the aperture part in one end part of the cover 20 in the direction perpendicular to the paper surface by a blast driving source and is sent out from the aperture part in the other end part. Thus, the LED array 5 heated by heat generation due to light emission of LED elements is cooled by the air current at a normal temperature and defects due to heat generation of the LED array 5 are eliminated. Since the air current does not flow to an array lens part 6, foreign matters such as dust are not stuck to a SELFOC lens 6.

Title: Semiconductor integrated circuit
Inventor: HASEGAWA TAKEHIRO
IPC: H03K3/037
Filed: 1991-01-25
Abstract: PURPOSE:To quicken the semiconductor integrated circuit by giving a first-out function to an output buffer so as to eliminate the effect of an internal delay of various FF circuits and a data latch circuit. CONSTITUTION:When a clock CK chances from '1' to '0', data is fetched and a level of a node N1 changes from '0' to '1'. A change in the level of the node N1 causes the falling down of a level of an output node N3 of a NOR gate G51, resulting in causing further the rising in a level of an output node N4 of a NOR gate N52. Then the rising of the level of the input node N1 enters directly an output buffer stage NOR gate G56 and an output Q1 falls down by receiving the rising. That is, a final output Q1=0 is obtained while no gate delay by two stages of NOR gates G51, G52 being components of the FF 1. Then the operation is similar to the case that input data (A=1, inverse of A=0) are inputted and latched by using the clock CK.

Filed: 1985-02-14
Abstract: PURPOSE:To measure simultaneously nuclear magnetic resonance (NMR) and electron spin resonance (ESR) by providing a means which applies pulse modulation on a microwave and setting widths of exciting pulses for ESR observation and exciting pulses for NMR observation. CONSTITUTION:A microwave irradiation coil 3 for ESR and a saddle type detection coil 4 for NMR are provided in a probe 2 for ESR-NMR simultaneous measurement.

Then, microwaves are oscillated to the widths of the exciting pulses for NMR and ESR observation and the intensi ty of a magnetostatic field is varied; and signals of NMR and ESR are sent to memories 17N and 17E and detected. Thus, the modulator 8 imposes pulse width modulation on the NMR and ESR, which are therefore measured simulta neously.
