Title: Inkjet recording head
Inventor: TAKEMOTO TAKESHI
IPC: B41J2/14
Filed: 1987-10-20
Abstract: PURPOSE:To make the construction of an orifice and a flow passage simple and reliable, by providing a base plate having a groove for guiding a recording medium, and an upper plate in tight contact with the base plate to form the groove of the base plate in the form of a pipe, and, elastically pressing the base plate and the upper plate. CONSTITUTION:An upper plate 1 is pressed against a base plate 2 uniformly by a leaf spring 6. The upper plate 1 is made of a ferromagnetic material, for example, iron or nickel, and a permanent magnet 8 is placed under the base plate 2. By the suction force of the magnet 8, the upper plate 1 and the base plate 2 are tightly contacted with each other, thereby to form an ink flow passage. A sponge 9 or the like is inserted between the leaf spring 6 and, the upper plate 1 and the base plate 2, so that the pressure is more uniformly applied. In the case of an inkjet recording head having a heat generating element in the flow passage, the jetting force or efficiency of a recording medium (ink) is deteriorated by the heat due to the heat generating element. At this time, however, if the pressing member is made of a material high in heat radiation or formed to have a larger area, the heat by the heat generating element can be radiated, whereby the jetting efficiency of the ink can be maintained continuously stable.

Title: Image memory reading circuit
Inventor: TAMURA YASUHIRO
IPC: G06F12/00
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To read data from the start address to end address of arbitrary internal cell address. SOLUTION: An enable signal is generated from a read start signal and a borrow signal by an enable generating circuit 14. A shaft register 41 shifts the enable signal by from 2<n> clocks to 2<n> +2<n> clocks. A counter enable signal is generated by an AND gate 16. A start shift selector 42 selects the signal shifted by the shift register 41 just for the value of the start address inside a 2<n> + start address. An end shift selector 43 selects the signal shifted by the shift register 41 just for the value of the internal end address of the 2<n> + end address + '1'. A comparator 44 compares the value of the internal start address with the value of the internal end address, and an AND/OR selector 47 selects the AND or OR of the output of the start shift selector 42 and the output of the end shift selector 43.

Filed: 1992-10-05
Abstract: PURPOSE:To facilitate data separation and multiplexing of different data by setting independently a frame position of low speed channel data on a channel and setting a frame length for each channel. CONSTITUTION:A multiplexer 1 allocates a data transmission for each channel in advance and sends low speed data DA, DB, DC together with a high speed clock CK2 at a time decided independently of a frame. On the other hand, a separator 2 demultiplexes the inputted high speed data at a time decided by a separator processing section 22 to allocate the data to a low speed channel and synchronization circuits 23A, 23B, 23C of a terminal interface 23 retrieve an added unique word before multiplexing to monitor a synchronization establishment flag FL. Then the processing section 22 reallocates data of other channel as to a channel whose synchronization is not established. Thus, synchronization is established for all low speed channel data and separated for each channel correctly.

Filed: 1984-12-19
Abstract: PURPOSE:To assure good atomization over a full operation region of an engine without forming a wall flow in a suction tube by allowing injection valve to penetrate a throat part and flow out with the aid of a fuel guide part. CONSTITUTION:A pressure difference is produced in response to opening of a throttle valve in engine operation, whereby air is introduced from the upstream into a nozzle 15 via an air introduction tube 31 and accelerated through a throat part 25 and allowed to flow into an air intake path 17.

Title: Hot-line insertion/extraction connector
Inventor: TANABE HIROHARU
IPC: H01R13/64
Filed: 1993-10-25
Abstract: PURPOSE:To lessen any damage on the contact of a hot-line insertion/extraction connector caused by spark discharge by driving a pin contact at a high speed by, making use of the restoring force of a spring, in the case of the contact opening speed of a power supply terminal. CONSTITUTION:The restoring force of a spring 13 is smaller than the insertion/ extraction force of catching a pin contact 15 that a socket contact 22 shows when the pin contact 15 is connected the socket contact to the contact 15, 22. Accordingly, the spring 13 is left contacted between the flange of the contact 15 and the flange of the cover 12 until the condition right before both contacts 15 and 22 separate from each other. At the instant when both a receptacle 2 and a header 1 separate from each other by driving them relatively right and left, the contact 15 is driven rightward quickly by the restoring force of the spring 13, and both are separated from each other quickly. Accordingly, the spark discharge time is smaller enough than that in the case of separation by man hand, so the spark discharge can be finished quickly.

Filed: 1989-10-13
Abstract: PURPOSE:To prevent the generation of crack in a glass state coating film by eliminating the glass state coating film in a belt type region on the semiconductor wafer periphery, after the glass state coating film is stuck on the whole surface of the semiconductor wafer. CONSTITUTION:An SOG film is formed by spin-coating liquid type spin-on- glass(SOG) 2 on a wafer 1, and baked in a baking furnace. Photoresist is spread on the film, and the resist film in a belt type part on the water 1 periphery is eliminated by photolithography. Next by using the resist film as a mask, the SOG coating film on the wafer periphery is selectively eliminated. Solvent of SOG 2 may be used as the SOG eliminating liquid in the above process, but high speed processing is enabled by using HF based etching liquid. After that, the resist is exfoliated and ordinary process is progressed. Thereby the generation of crack in a glass state coating film like SOG 2 stuck and formed on the water 1 surface can be prevented.
