Title: Thermal head
Inventor: ISHIMA KAZUMI
IPC: B41J29/377
Filed: 1988-12-28
Abstract: PURPOSE:To conduct a cooling with high efficiency and simple construction by providing a cooling liquid flow path for cooling a heating element within a head substrate, an expanded-diametered part in a part of the liquid flow path, and a heat release member in the vicinity of the expanded-diametered part. CONSTITUTION:The rate of flow of a cooling liquid which flows through a flow path from a cooling liquid inlet 6 to a cooling liquid outlet 4 is lowered at an extended-diameter part 3 according to the cross-section area thereof. Therefore, a sufficient heat release time by a heat release fin 5 is ensured. Additionally, if the extended-diameter part 3 of the flow path has the cross-sectional area and length suitable for an ink reservoir, it can also serve as an ink reservoir. If a quantity of heat generated in a heating part is too large, it is preferable that a forcible cooling is conducted by blowing air to the fin 5 by a fan. In this manner, the heating element can be efficiently cooled with a simple construction.

Title: Sample pretreatment device
Inventor: TAKEHARA HIROKO
IPC: G01N1/28
Filed: 1990-11-30
Abstract: PURPOSE:To enable a sample to be decomposed and condensed without being affected by contamination from environment by using a structure which allows decomposition of the sample and condensation of the decomposed sample to be operated continuously using a same container. CONSTITUTION:A specified amount of decomposition liquid 3 is fed to a container 2, a sample wafer 4 is placed on it, a closing lid is placed from an upper part, and then a screw is clamped. When a decomposition device is placed on a heater 1 and then is heated, a decomposition liquid is evaporated, a thin film on a surface of a wafer is dissolved, and then is cooled and dropped. It is repeated while heating for a certain time by a heater and a thin film including a contamination substance on the surface of the wafer is dissolved entirely. When the sample after decomposition operation is condensed by the column condensation method, the container 2 with the decomposition liquid 3 is removed and is connected to a container for condensing column 7. By pressing a pure high-pressure gas from a gas introduction port 8, the decomposition liquid 3 is introduced to a condensation column 10 through a discharge port 9 and a target constituent is condensed, thus enabling an extremely small amount of wafer contaminated object to be analyzed with a high sensitivity and high accuracy.

Title: Housing device for wiper blade
Inventor: TANAKA HIKARI
IPC: B60S1/04
Filed: 1987-12-28
Abstract: PURPOSE:To surely cover a blade with a cover body at the time of housing by providing an elastic element for energizing a housing cover body to an opening or a closing side midway while opening or closing same, and an operating body which is brought into contact with the blade getting in or out of a housing chamber and which operates the cover body to an opening or a closing side. CONSTITUTION:When a cover body 12 is in a posture of being closed or opened, the cover body 12 is energized toward that side by means of an elastic element 13 which acts beyond a fulcrum to maintain the posture in the corresponding condition. When the blade 5 gates out of a case body 11, a bracket 4 is brought into contact with the inner face of the cover body 12 and pushes up same to change the posture thereof to an open side while, on the other hand, at the time of getting into the case body 11, the bracket 4 is brought into contact with an operating body 12c and depresses same to change the posture of the cover body 5 to a closing side. Thus, when wiping is not necessary, the blade 5 is housed in the case body 11 in a condition of being covered with the cover boyd 12. Hence, the opening/closing of the cover body 12 is automatically carried out by means of the getting in/out action of the blade 5 with respect to the case body 11.

Title: Coder
Inventor: SETA HIROYUKI
IPC: H04N1/417
Filed: 1987-12-28
Abstract: PURPOSE:To improve the data compression rate by obtaining the degree of correlation of picture elements between lines of a coded object image, widening the range of distance between change points with the 2-dimension coding system almost to be applied thereto with a low correlation and increasing the rate of application of the 2-dimension coding system. CONSTITUTION:In case of coding image such as a document, the interline correlation of coded object image is obtained by an inter-line correlation calculation section 12. The inter-line correlation is informed to a 2-dimension coding range decision section 13. The decision section 13 decides the 2-dimension coding range in response to the inter-line correlation applied from the calculation section 12 and informs it to a coding section 11. The range is wider as the inter-line correlation is lower. The coding section 11 applies the coding of the coding object image while using the 2-dimension coding and the linear coding system based on the range informed from the 2-dimension coding range decision section 13 switchingly. Thus, in case of the coded object image with a low inter-line correlation, the rate of application of the 2-dimension coding system is increased and the data compression rate is improved.
