Title: Float chamber of carburetor
Inventor: EIBINDO BOIESEN
IPC: F02M5/02
Filed: 1994-04-14
Abstract: PURPOSE: To prevent the concentration of mixture from increasing in violently vibrating a vehicle in traveling. CONSTITUTION: A float bowl 12 is extended across the wall of a housing 14 in the front and rear parts of a carburetor. When the oil surface 48 is a desired height and if excessive fuel is added thereto by sloshing and foaming of the fuel in the float bowl, this constitution can reduce the increase in the oil surface and reduce the ill effects affecting on the fuel flow. Extension parts 44, 46 in the frontward and rearward of the float bowl 12 are gradually bent as shown by numerals 50 and 52 in Fig. respectively. The bending of the front extension part 44 and the rear extension part 46 of the float chamber 12 can reduce or prevent the foaming of the stored fuel in abrupt movement of the carburetor generated in a vehicle passing over bumps continued at small intervals.

Filed: 1985-04-12
Abstract: PURPOSE:To obtain stably always the trap attenuation being the severest to the effect of a spurious wave by selecting the thickness of a substrate of a surface acoustic wave device so as to satisfy a prescribed relation. CONSTITUTION:An input electrode 2 and an output electrode 3 are provided on an Li2B4O7X-cut substrate 1 having a plate thickness (t) to constitute a surface acoustic wave device. In the device, in order to avoid the effect of a spurious wave due to the resonance in the broadwise direction onto the trap attenuation, the correlation between the plate thickness and the trap attenuation is obtained and the optimum thickness to a desired frequency is obtained, then it turns out that the effect of the spurious wave due to the broadwise resonance is minimized when the plate thickness (t) satisfies equation of 2.37Xn/t<t<[2.37X(n+2)]/f, where (n) is an odd number, (f) is the trap frequency of the filter pass band and (t) is the thickness of the Li2B4O7 plate. Thus, the surface acoustic wave device eliminating any spurious wave is obtained by using the substrate 1 having a plate thickness satisfying the said equation.

Title: Flat type fluorescent lamp
Inventor: MISONO KATSUHIDE
IPC: H01J61/30
Filed: 1989-03-30
Abstract: PURPOSE:To simplify encapsulation of mercury and reduce crack initiation at the seal part by forming a pair of cold cathodes from Hg alloy, and by forming lead-in terminals from a thin wire or foil having a low thermal conductivity. CONSTITUTION:When mercury is to be encapsulated in a flat sealed vessel 16, a pair of cold cathodes 17a, 17b are high frequency heated upon exhaustion of the vessel 16, which causes evaporation of a certain amount of mercury from the cold cathodes 17a, 17b consisting of Hg alloy, and it is encapsulated in the vessel 16. The heat from high temp. heated cold cathodes 17a, 17b is conducted to Dumet wires 19a, 19b, respectively. Low thermal conductivity of these Dumet wires 19a, 19b suppresses heat conduction from the cold cathodes 17a, 17b to the seal part to lead to prevention of this part from temp. rise, and also crack initiation at the seal part can be reduced. Use of a foil of a conductor in lieu of Dumet wire will provide the same effect.

Filed: 1982-05-07
Abstract: PURPOSE:To simplify the removal of a storage device and to improve the utility value as an external memory, by detecting the mounting of the storage device, attaining the transmission of data with the mounted device main body such as read/write of the storage device through the detection, providing a removal preventing means of the storage device using a signal generated at the data transmission, and protecting the stored data against the mounting and removal of the storage device. CONSTITUTION:In inserting a memory cassette 5 to a word processor main body, each connecting terminal is connected. Even if the power supply of the word processor main body is applied, when no selection signal is outputted, the inserted memory cassette 5 remains in stand-by state as it is. When the memory cassette 5 is inserted correctly and the connecting terminals VCST and GND are connected respectively, since the power supply VCC of the main body is higher in voltage than the voltage applied from a battery 52 in the cassette, hereafter the power is supplied from the main body. In inserting the memory cassette 5, a terminal S of a CPU 11 is a ground level through connecting terminals CSTiN1, 2 and the insertion of the cassette 5 is detected. Since a transistor 71 or 72 is conductive during the read/write, the removal of the memory cassette 5 is prevented with the transistor.
