Abstract: A method for cleaning a liquid ejection head, including a flow path forming member forming a liquid flow path, a heat generating resistive element, and a coating layer covering the heat generating resistive element and in contact with the liquid, in which the heat generating resistive element is made to generate heat and the liquid is made to be ejected from ejection ports, the method including: applying a voltage to the coating layer to produce an electrochemical reaction between the coating layer and the liquid, and causing the coating layer to be eluted into the liquid, thereby removing kogation deposited on the coating layer; and causing the heat generating resistive element to generate heat and causing the liquid to be ejected from the ejection ports while a voltage is applied to the coating layer continuously or intermittently, thereby eliminating air bubbles generated due to the electrochemical reaction.

Abstract: A liquid ejection head includes a substrate and a flow path forming member. Energy generating elements that generate energy with which a liquid is ejected are formed on the substrate. The flow path forming member is disposed on the substrate and a flow path which encloses the energy generating elements is formed using the flow path forming member. Plural ejection ports that are in communication with the flow path are formed in the flow path forming member. A groove portion extending obliquely with respect to an X direction in which adjoining ejection ports are arranged is formed between the adjoining ejection ports in the flow path forming member.

Abstract: A clip is provided which allows the lengths of paired leg portions extendable and contractible in the same manner as a pantograph to be shorter in a state where the clip is mounted on a silencer, than in the conventional art. Third hinge portions which connect the second leg portions of the opposed leg portions to the common connection leg portion at a side opposite to first hinge portions which connect the insertion base portion to the first leg portions are formed at an inner side so as to be closer to an insertion axis for a hole of the silencer than the first hinge portions, whereby a folded state is obtained with such a small angle that each first leg portion and each second leg portion are in contact with or close to each other.

Abstract: A liquid discharge head includes a substrate and a flow-path-forming member that forms a plurality of flow paths and discharge ports that are in communication with the flow paths on the substrate. Liquid is to be discharged from the discharge ports. A space is formed between the plurality of flow paths and is filled with a filling material. In the case where a direction in which the liquid is to be discharged from the discharge ports is an upward direction, a top surface of the filling material is positioned at the same height as a face surface of the flow-path-forming member or is positioned higher than the face surface of the flow-path-forming member in the upward direction.

Abstract: Methods, systems and computer program products for implementing a polling process among one or more flash memory devices are described. In some implementations, the polling process may include sending a read status command to a flash memory device to detect the ready or busy state of the flash memory device. A status register may be included in the flash memory device for storing a status signal indicating an execution state of a write (or erase) operation. A solid state drive system may perform the polling process by reading the status register of the flash memory device.

Abstract: A semiconductor device including an electronic circuit, a memory, and an error detecting module. The electronic circuit is configured to receive an input signal having been generated by a test module, and generate an output signal based on the input signal. The memory is configured to store a predetermined output value that is expected to be output from the electronic circuit based on the electronic receiving the input signal, wherein the predetermined output value is stored in the memory prior to the input signal being generated by the test module. The error detecting module is configured to (i) generate a sample value of the output signal, (ii) compare the sample value of the output signal to the predetermined output value stored in the memory, and (iii) generate a result signal that indicates whether the sample value of the output signal matches the predetermined output value.

Abstract: Systems, methods and computer program products for programming data into a multi-plane memory device employ a multi-plane data order. To allow multiple data pages to be programmed without a need to increase the size of page buffers, in some implementations, a data transfer scheme at which the data pages are programmed can be manipulated. Specifically, data across all channels can first be programmed into a first plane of the multi-plane flash memory device in parallel. While the data transfer program operation is in progress, data to be programmed into a succeeding plane (e.g., plane “1”) can be read into and cached in one or more page buffers. After the data transfer program for the first plane is complete, data cached in the page buffers can be immediately latched and programmed into the multi-plane flash memory device.

Abstract: A hot-air type heater apparatus includes an air intake for receiving air from an area to be heated by the hot-air type heater apparatus. In particular, the air intake includes a suction fan for drawing air from a surrounding area into the hot-air type heater apparatus. The air from the surrounding area enters the hot-air type heater through the air intake. The hot-air type heater also includes an air passage to direct the air received from the air intake to a ceramic heater. The air passage allows the air received from the air intake to flow into the ceramic heater. The ceramic heater is then able to rapidly increase the air temperature. Furthermore, the hot-air type heater includes a warm air outlet coupled to the ceramic heater. The warm air outlet outputs the air heated by the ceramic heater into the area to be heated by the hot-air type heater apparatus.

Abstract: A portable heater and humidifier apparatus is provided. The apparatus includes a housing with an inlet for receiving air from an area exterior to the housing. The housing includes an air passage disposed therein with a ceramic heating element located inside the air passage. The air passage includes a partition stationed between the ceramic heating element and a heater outlet that is used to exhaust heated air. A fan within the housing is used to direct air from outside of the housing into the air passage. The fan then directs the air through the ceramic heating element. A portion of the heated air continues to flow within the air passage until the heated air is exhausted from a heater outlet. The remaining heated air is diverted to a humidifier through an aperture located within the air passage. The heated air is then combined with fine water droplets generated by the humidifier to emit water vapor or mist from a humidifier outlet.
