Patent JP-H02196269-A (JP)
Title: Fixing device
Inventor: KURENUMA TAKEROU
IPC: G03G15/20
Filed: 1989-01-26
Abstract: PURPOSE:To prevent a detected temperature from being affected by an ambient temperature by integrally forming a thermistor temperature detecting part, which detects the surface temperature of a fixing part roller, together with a separation nail around the top of the separation nail. CONSTITUTION:The separation nail 6 is supported so that the nail top comes into contact with the face of the fixing part roller 1. In the separation nail 6, the thermistor temperature detecting part protrudes outward in a position close to the nail top, from a detecting part 7 through the inside of the separation nail 6. By this device, a temperature detected by the thermistor is not affected by the ambient temperature, and a strict gap control is not needed. The roller 1 may be damaged by its contact with the separation claw 6, but it is never damaged any more.

Title: Tuning fork type quartz oscillator
Inventor: MOMOZAKI EIJI
IPC: H03H9/00
Filed: 1981-02-04
Abstract: PURPOSE:To reduce the fluctuation of frequency due to the temperature, by using a quartz thin plate which is cut out with a rotation of -15 deg.-+5 deg. around an electric axis. CONSTITUTION:A tuning fork type oscillator having a flectional oscillation is cut out of a quartz plate which turns in a range of -15 deg.-+5 deg. around an electric axis (x) in a quartz crystal. The top temperature of the frequency temperature characteristics varies by changing the W/L (W, L: width and length of arm  of tuning fork respectively). Accordingly a quartz oscillator having good temperature characteristics at a room temperature is obtained in a range of W/ L>=0.13. An electrode structure in which the series resistance can be reduced by  20-30% compared with a basic wave by using a higher harmonic flectional  oscillation as an oscillation mode. Thus the oscillation can be easily obtained.

Title: Low pressure casting
Inventor: MURATA AKIKAGE
IPC: B22D18/04
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To shorten a cast cycle time. SOLUTION: Pouring gate members 5, 5 being arranged in a way to block a molten metal flow channel under a status that outer peripheral edges of the wire net 5a, 5a are buried in the peripheral walls of the pouring gate members are formed with a sandmold casting die. After the gate members are inserted from the above against gate portions 22c, 22c in a bottom die 22 of the mold 2, a molten metal is poured into the mold 2 through a stoke 3, a pouring basin 4, gate sleeves 22d, 22d and the gate members. Because a thermal insulation of the gate portions are carried out by forming the gate member with a sand, even when the bottom die is cooled down, a solidification of the molten metal at the gate portions can be delayed compared with the molten metal of the other portions.  Thereby, generation of a shrinkage cavity in the casting article is prevented by maintaining a riser effect until the molten metal solidification is completed. At the time of the pattern drawing, as the gate members are made to be drawn together with the casted article, a generation of a crack inside the caste article, or the gate break can be prevented by making a drawing resistance small.
