Filed: 2019-10-17
Abstract: To form a device chip without deteriorating quality.SOLUTION: A wafer processing method for dividing a wafer in which a plurality of devices are formed into individual device chips comprises a polyolefin-based sheet arranging step, an integrating step, a dividing step, and a picking-up step. The polyolefin-based sheet arranging step positions the wafer in an opening of a frame and arranges a polyolefin-based sheet in a rear surface or a surface of the wafer and an outer periphery of the frame, the opening housing the wafer. The integrating step heats the polyolefin-based sheet and integrates the wafer and the frame by thermal compression bond via the polyolefin-based sheet. The dividing step forms a shield tunnel in the wafer by irradiating the wafer with a laser beam of a wavelength having permeability to the wafer along the division schedule lines and divides the wafer into individual device chips. The picking-up step cools the polyolefin-based sheet, pushes up the device chips, and picks up the device chips.SELECTED DRAWING: Figure 4

Title: Shower device
Inventor: NONOYAMA MASAO
IPC: A47K3/28
Filed: 2019-11-29
Abstract: To avoid a situation in which hot water flows reversely from a shower head side to an upstream side of a water tap even when a supply pressure of the hot water decreases due to a water supply failure or the like while a shower device is used.SOLUTION: A shower device of this invention includes a check valve 20 on a downstream side of a water tap. The check valve 20 is urged in a valve-closing direction by which a passage 11 of hot water is closed, and meanwhile, opens when a pressure of the hot water on a water tap side surpasses a valve-opening pressure. One end of an open passage 30 is connected to the downstream side of the water tap, and the other end is open to the atmosphere. An open valve 31 is disposed in the open passage 30 and, when the pressure of the hot water that is supplied to the downstream side of the water tap decreases below a predetermined pressure, the open valve 31 opens to introduce the atmosphere. Accordingly, a reverse flow of the hot water can be prevented by closure of the check valve 20 even when the supply pressure of the hot water decreases to a negative pressure due to a water supply failure or the like. Furthermore, since opening the open valve 31 introduces the atmosphere through the open passage 30, a situation in which the hot water flows reversely from the shower head side to the upstream side of the water tap can be avoided.SELECTED DRAWING: Figure 4
